Renault Sandero 1.6 16V

Engine:1.6

I took Sanechka for recycling in an Auto-mailer in New Riga in November 2011, I had to wait six months in Moscow, in Oryol the Vozrozhdenie officials had 8 thousand rubles just for an auto transporter from Framos they ripped off, and they didn’t work with recycling workers, but for me I had to sell my Opel Oksanka, by the way, in this case, the Meager's dealers helped, because they did not have our region on the list for scrap cars, they decided everything in Moscow, and my Oksanka was also removed there. I took the car in Prestige, issued a comprehensive insurance there, even threw off almost 2 thousand rubles, and the insurance cost 27 thousand rubles. Registration with the installation of protection along the arches and everything else took place in 2 days (it was a weekend), I managed with all the special stages (leather steering wheel, passenger airbag, molding, windows in a circle, total 534 - 47 \u003d 487 thousand rubles .. taking into account the bonus In the salon Eagle put the signalization, which is great added convenience to the central lock.

The first thing that surprised me was that the capacity of the tank against the declared 50 liters consumes 62 liters. 700 gr. - checked at three gas stations in Bryansk, Smolensk and Vitebsk - confirmed by gas station sensors. I fill 95, it was in the tank and in the cabin. The brushes on the driver's side need to be changed immediately, I took a frameless one 5 cm longer than the standard one, and I'm quite satisfied. I took winter tires in the cabin Nordovskaya with a car, summer was Amtelka, slightly noisy, but serpentines and along the gorges in Abkhazia showed very decently. By the way, driving long distances of 1600 km on the back (and I'm 50 years old) in the seat did not affect, thanks to the adjustments in 2 planes. As for the inconveniences with the rear window lifters, I don't see any big problems, and I don't have to use it often. As for the kondeya, I especially felt the charm of his presence in the Sochi gassed tunnels when traveling to Abkhazia, and when from the sea, tired of the sun, it also invigorates great. On the track, I didn't really feel that he was pulling the car. The ascent to Dzhugba 2-3, the transfer of my mechanical five-step, quite clearly picked up. I specially tried the doors to close on a car hung out on a diagonal on mountain gravel serpentines (those who went to Kamany to the grave of John Chrysostom, they represent), usually close without straining. Before joining the lock, the back door has to be held so as not to slam.

I was surprised by the trunk, with a passenger sitting in the back (16-year-old daughter) and two backs folded, 6 boxes with glass containers and two decent trunks with things, plus a 50-liter metal tank were placed. By the way, few wrote about optics in the dark, neither Polo nor Rio shine so impressively, long-range players respectfully switch at a respectable distance, seeing Sanechka's optics, lupata, which is what it is.

For almost two years of operation, sores in the near, parking light did not touch me, but I had to tinker with the cigarette lighter fuse, thanks to Renovodov they prompted that on the fuse cover it is designated as an autoradio, this is a nude, although it is possible by typing or a tester, if such a glove box available. As for the driving experience: overview, informative. More attentively when turning 90 degrees, at a speed of 90, the roll is noticeable, although with its clearance the machine is not a rally car.

After 3,000 km of run on the road to Moscow beyond Tula, I decided to test for speed - I spun up to 170 km / h jeeps with their own weight did not risk on these potholes, after takeoff from the jolt they had to fly for a long time in an uncontrolled flight.

Now about the spare wheel: who was not too lazy or how life made me that there was already a lesson. After a trip to Lipetsk in the rain in the dark, I caught such a dent with the driver's wheel that I was even surprised in the morning when examined, the outer visible part of the disc and the rubber itself without a flaw and tubeless did not lower, which means the original is a disc (20 thousand rubles per circle) and not the great Chinese duralum. But miracles do not happen in the world and the inner part of the rim had to be straightened already in Orel. There, in the autumn, in the rain, I felt all the delights of replacing with a spare wheel, but if I wiggle a couple of three times, then this spare wheel from the underworld of Sanka's backside is not so scary.

General impressions of Sanechka - GUD. Casco itself, by the way, also paid off with a head, in the parking lot the neighbors were teranuli, on the paint without a dent 10-12 cm along the top of the rear wheel arch and a bit of the side of the rear bumper. The official "Renault Renaissance" Eagle estimated at 26,000 rubles. for this, moreover, only the plastic mounting plate for the mudguard was replaced, and everything else was painted - moreover, the rear bumper was repainted right up to the number, such as so that the parts did not differ in color. Plus, when I drove from Moscow from the passenger compartment, a stub of a cable jumped out from under the truck near Serpukhov, a loop with a piece of a loose hedgehog, on the cliff the speed was low, about 90-100 km / h, the car was only from the passenger compartment, and I drove, passing between wheels this flying lump. In the saloon of the officials on the lift, where I presented the machine for checking, it was revealed that the corrugation of the outer anther was punctured (after all, a piece of cable hooked it), repairs under insurance without replacing iron, it did not suffer, but only for dismantling, filling grease and replacing the boot cost a ticket to Ingosstrakh for 5,600 rubles. It's up to you to judge whether a new car needs a CASCO or not, under warranty from the officials

For compact models Renault Sandero, the French manufacturer Renault has provided the following options for equipping power plants:

• 1.2-liter "four";
• engine 1.4;
• a more uprated version with a 1.6 engine.

The last of the indicated units has two versions of the block head:

• 8-valve design;
• more progressive 16-valve mechanism.

All motors with 8 and 16 valves are impressively reliable and will delight you with an outstanding resource. This is confirmed by a galaxy of reviews that tested the car in practice by the owners.

Despite this pleasant fact, one should not remain silent about the presence of some common problems in engines with 8 and 16 valves. This applies to the "tripling" of the unit, as well as unstable operation at idle and during acceleration.

If the working volume is 1.149 cubic meters. cm?

This unit is factory marked "D4F" and is the smallest among the engine family. It is endowed with a modest power - only 75 liters. sec., which is achieved when the tachometer needle "rests" at 5.5 thousand revolutions. The maximum torque that the engine is capable of is 107 Newtons. This modest value is realized in practice at 4250 rpm.

The power supply system is quite modern, since distributed injection is present in its design. The in-line arrangement of the cylinders and the 16-valve timing mechanism are the distinctive attributes of this unit. Each of the cylinders has a diameter of 79.5 mm. Such an indicator as the compression ratio is 9.8 units.

Note that the engine in question is present only in the second generation Renault Sandero, including the Stepway version. The timing is driven by a belt, and there are two camshafts in the head of the block.

Important! One should not neglect the need to comply with the scheduled frequency of belt replacement, because when it suddenly breaks, there is no alternative "meeting" of 8 and 16 valves with pistons, which involves the owner's wallet in the "game" with the intriguing name "overhaul"!

Many owners of a 1.2-liter Renault Sandero, including the Stepway version, have noted the "sluggish" dynamics of the car, but practical users will appreciate this modification with modest fuel consumption. According to the specialists of the manufacturing company, the resource of the designated motor is approaching a fantastic "bar" - 1 million km. Here, practice puts everything in its place, since subjective factors of operation have a significant impact on the formation of the resource indicator.

This motor is not devoid of flaws, manifested in the tendency to "triple" or upset with the appearance of extraneous sounds.

Moving on to a volume of 1.390 cubic meters. cm.

Versions, when the 1.4 engine of the 5-door Renault Sandero, including the Stepway version, proudly represented the first generation of the model. The power of these “fiery hearts” is also hopelessly modest. It is equal to 75 "horses" (or 55 kW), which are fully "open" at 5500 rpm. The "bar" of torque here is slightly higher (than in 1.2) and amounts to 112 Nm. This torque maximum is reached at 3000 rpm.

Among the design features, we single out the 8-valve timing mechanism. This version of the engine, based on feedback, shows an increased sensitivity to fuel quality. This circumstance can provoke the "desire" of the engine to "triple" and not maintain the stability of the idle speed.

The compression ratio here is equal to 9.5: 1. The timing belt is activated by means of a belt, which should be replaced with a new analogue every 60 thousand kilometers traveled. The resource of the unit is also significantly large. Its peak, as in the previous version, is approaching 1 million km. When the mileage of the car considered here becomes "respectable" and "triplet" with unstable revolutions become permanent attributes of the unit, it is recommended to visit the specialists. First, it is advisable to examine the timing belt drive, since when its wear is close to critical, a jump (by 1-2 "teeth") is possible, which is likely to provoke the appearance of these symptoms.

Among the unpleasant features of the Renault Sandero car, including in the Stepway version, the owners also note an insufficient level of accelerating dynamics. The faulty ones will help to aggravate the position of the "pilot":

• throttle assembly;
• the Lambda probe;
• candles, fuel filter, etc.

Hope for a volume of 1.598 cc cm.

As previously noted, Renault Sandero's 1.6-liter "hot hearts" had 2 variants of the design of the motor heads (according to the number of valves). In view of this, their power parameters are different, namely:

• 82 l. from. (60.5 kW at 5000 rpm) are present in the 8-valve version;
• 102 "horses" (75 kW at 5750 rpm) harnessed a 16-valve unit.

The cylinder diameter for each version is identical - 79.5 mm, and the compression ratio differs: 9.5 to 1 and 9.8 to 1, respectively.
The torque of the "eight-valve" reaches 134 Nm at 2800 rpm, and 16 valve versions have 145 Newtons at 3750 rpm in the arsenal.

Both engines are modern and "armed" with an electronically controlled multipoint injection system.

Similar to the previous versions, the timing drive of these motor versions is activated by means of a belt drive.

Among the unpleasant features, the owners distinguish:

• unstable speed during warming up;
• short-term dips during idle.

The most common reasons are failures of sensors: "lambda", idle sensor, mass air flow sensor, etc.

Due to the presence of a threat similar to previous versions of the timing belt breaking in a timely manner, we strongly recommend not to delay this procedure when the replacement date is approaching.

Top volume - 1.998 cubic meters cm.

The uniqueness of this modification for the European continent lies in its purpose to officially please only Latin American motorists. The debut of the version took place in Buenos Aires. The 2.0-liter Renault Sandero with the exciting 'RS' logo already has some serious potential. Its 145-horsepower naturally aspirated engine with the F4R index is capable of realizing a serious torque indicator - 198 Newtons. The timing of the "fiery motor" is similarly driven by a belt. As a power system, there is a multipoint distributed injection.

The design of the block head implies:

• A 16-valve version of this assembly;
• in-line arrangement of 4 cylinders, the diameter of each of them is 82.7 mm;
• the maximum piston stroke is 93 mm;
• the compression ratio is surprising - 11.2 to 1.

So far, one should not make premature forecasts in terms of the resource of this unit due to the novelty of the modification. There is a hope that the developer has taken a set of targeted measures to eliminate the disadvantages of engines indicated here, belonging to the indicated modifications of Renault Sandero.

Let's take an interest in the experience of car owners

1. “I leaned towards choosing the Renault Sandero with a 1.2-liter unit. Despite the many complaints about the weak towing power, I can optimistically note that this modification is optimal for city traffic. The level of fuel consumption, when compared when the engine is 1.4 and engine 1.6, is guaranteed to please. The car is simple in terms of performing maintenance measures. Sometimes it can "triple", but as a reason I tend to low-quality fuel. "
2. “A couple of phrases about the engine - a 16-valve 1.6 engine. Recently, triplets have become more frequent during warming up. Masters recommend checking the throttle assembly and sensors, which I plan to do in the near future. Overall, Renault Sandero did not disappoint. ”
3. “If we compare 1.2 with when the engine is 1.6 or even the engine 1.4, then undoubtedly the palm should be addressed to the latter. 1.2-liter volume is not enough, especially the lack of recoil is noticeable on the track or in a long climb. But on the other hand, the units are reliable and resource-intensive, which is good news. "

Renault Sandero is a modern and economical hatchback that meets the most modern requirements. The price of this car is extremely low, which allows it to stand on the level of the most popular cars in the Russian market. The secret of its success is a range of economical engines designed for a long service life.

At the moment, there are three different 1.6 liter engines with 8 and 16 valves: 82, 84 and 102 horsepower. Let's get to know them in more detail and consider them from all sides.

Small but smart: an overview of the lowest-powered motor in the lineup

This engine has 82 "horses" at its disposal with a volume of 1.6 liters. It is offered only in basic configurations and is positioned as one of the cheapest and simplest.

Acceleration time to hundreds of engine 1.6 16kl. layout is impressive: with its low power, it is able to accelerate Sandero to the specified figure in just 11.9 seconds. And this despite the fact that instead of direct injection, a distributed system operates here. The tank of such a car can be filled with both 95 and 92 gasoline. True, as practice shows, passport data approximately resemble real ones only if a higher octane is used.

With regard to power, it is 60.5 kilowatts, which is equivalent to 82 horsepower. At 5,500 rpm, the engine delivers an impressive 134 Newton meters of torque, allowing the driver to feel confident in hard starts and uphill driving.

According to the manufacturer, top speed with this 82-horsepower 8-cl. motor is 171 kilometers per hour. Consumption cannot but rejoice: on 95 gasoline in a city traffic jam, a car will consume a significant 9.8 liters per 100 kilometers, and on the highway the appetite is almost halved and will amount to "funny" 5.8 liters.

Reviews of motorists who were lucky enough to become the owners of Renault Sandero with this engine tell about the driving performance of the car ambiguously. Opinions agree that the motor is clearly not intended for active driving and is more suitable for those who are used to saving money: “I bought a car, mainly for leisurely trips to the country house and barbecues in the summer, so I don’t complain about sluggish dynamics. Yes, the car is really not very sporty, but the consumption cannot but rejoice: never in my memory did it exceed 9 liters, judging by the on-board computer. As for the rest, for 50 thousand kilometers, oil consumption and malfunctions were not noticed, I am satisfied with the car. "

Middle brother: exploring the sweet spot in the engine range

The second 84-horsepower engine is of the greatest interest, since it is in extremely high demand among the buyers of this car. At the heart of the design, it has all the same 8 valves and a working volume of 1.6 liters.

The first thing you should pay attention to in 1.6 8kl. motor with 84 "horses" - acceleration time. If you believe the official documentation, at 84 forces, the car reaches 100 kilometers per hour in just 11.5 seconds: almost half a second less than in the case of the 82 hp unit.

The second but no less important note for the 82 hp motor is torque. Already at 5500 rpm, this figure is about 128 Newton meters, which, oddly enough, is almost ten less than in the first case.

The maximum speed that a car equipped with this power unit can reach is 174 kilometers per hour, which is three units higher than that of an 82 hp engine with 8 valves.

The passport consumption of the engine in the urban cycle is rather big 10 liters of 95 gasoline per 100 kilometers. Outside the city, the car promises to consume 5.6, which makes it possible to judge it as not the most economical option in the entire line.

Reviews of this 82 hp engine are generally positive. The only thing that can be a reason to think about it is the periodic oil consumption, which sometimes begins with the odometer overcoming the 120-150 thousand kilometers mark: “My 2012 car is equipped with an 84 hp K7M unit. In general, the car raises no objections and goes exactly as I need. A fly in the ointment was an unexpected oil consumption after the mileage exceeded 140,000. I think this is due to the use of inexpensive oil, but I will not buy this motor again. "

"Top" motor in detail

The largest potential and the highest technical characteristics have an engine with a capacity of 102 hp, having a volume of 1.6 liters and not the usual 8, but 16 valves. The 102-horsepower engine is offered as a pair with a five-speed manual and four-speed automatic transmission.

Acceleration of a car with a 102-horsepower engine to hundreds of kilometers per hour takes place in a record for Renault Sandero 1.6 16kl. 10.5 seconds. At 5500 rpm on a 102-horsepower engine with 16 valves, a torque of 145 Newton meters is achieved, and the maximum speed is impressive and reaches, judging by the documentation, at 16 liters. layout 180 kilometers per hour. Fuel consumption in the city, thanks to the use of not 8, but 16 valves, is low and only 9.8 liters per 100 kilometers, and outside the city the car will require no more than 7.1 liters.

It is also necessary to change after 15 thousand km, then it is better to combine these works, because it will be easier to turn the crankshaft when checking the belt. The surface of the toothed part of the belt should not have folds, cracks, undercuts of teeth and peeling of fabric from rubber. The underside of the belt should be free of wear, exposing the cords, and burn marks. There should be no delamination or fraying on the end surfaces of the belt. The belt must be replaced if traces of oil are found on it.

Gas distribution mechanism drive:

• 1 - toothed pulley of the crankshaft;
• 2 - timing belt;
• 3 - tensioner roller;
• 4 - toothed pulley of the camshaft drive of the exhaust valves;
• 5 - toothed pulley of the camshaft drive of the intake valves;
• 6 - support roller;
• 7 - toothed pulley of the coolant pump

Remove the protection of the power unit and the right mudguard of the engine compartment.

We substitute an adjustable stop (for example, a jack) under the oil pan through a wooden block. Without using an adjustable stop, you can slightly raise the right side of the engine with a mounting paddle (by the oil pan, resting the paddle on the subframe).

Raising the oil pan, insert a wooden wedge between the subframe and the oil pan.

With a spanner wrench "18" we loosen the tightening of the bolt fastening the support to its bracket.

We take out from the two holders located on the support bracket, the fuel supply pipe to the rail, the fuel vapor removal pipe from the adsorber and the wiring harness.

Using the "16" head, unscrew the three bolts securing the support bracket to the upper timing cover ...

… And three bolts securing the support to the body.

Remove the right support of the power unit assembly with the bracket.

Using the "13" head, unscrew the three bolts and two nuts securing the upper timing cover.

Remove the upper timing cover.

Using the “18” head, turn the crankshaft clockwise by the bolt securing the accessory drive pulley and visually assess the condition of the timing belt.

The belt tension can be estimated by the location of the automatic belt tensioner indicators.

With normal belt tension, the movable indicator should coincide with the notch of the fixed indicator of the tensioner (for clarity, shown with the lower timing cover removed).

If the movable pointer is offset from the fixed one:

• counterclockwise - belt tension is insufficient;
• clockwise - the belt will be tightened.

To adjust the belt tension, a hatch closed with a lid is provided in the lower timing cover (shown on the removed cover for clarity).

Pulling up, remove the hatch cover.

Having loosened the tightening of the tensioner fastening nut with a “13” wrench, turn the roller clockwise with a “6” hex, tightening the belt.

Holding the roller in this position, tighten the tensioner mounting nut. Turning the crankshaft two turns clockwise by the bolt securing the accessory drive pulley, check the belt tension again and, if necessary, repeat the adjustment. Install the removed parts in reverse order.

To replace the timing belt, remove the accessory drive belt.

Remove the upper (see above) and lower timing cover.

To remove the lower timing cover with the "8" head, unscrew the four bolts of its fastening.

Remove the bottom cover.

When unscrewing the bolt securing the accessory drive pulley, it is necessary to block the crankshaft from turning. To do this, the assistant must engage fifth gear and press the brake pedal. If at the same time it is not possible to unscrew the pulley mounting bolt due to crankshaft turning, then the shaft must be locked. The crankshaft position sensor must be removed to gain access to the flywheel ring gear.

To do this, turn off the two bolts with the head "10".

We remove the sensor.

We insert through the window in the clutch housing a mounting blade between the teeth of the flywheel crown, designed for starting the engine with a starter.

Attention! Do not damage the surface of the teeth required for the operation of the crankshaft position sensor (they are much larger).

Using the "18" head, we unscrew the bolt securing the accessory drive pulley.

We take out the bolt and washer.

Remove the accessory drive pulley.

If it is difficult to remove the pulley, we evenly pry it from different sides with a mounting blade.

There are no special alignment marks on the crankshaft and camshaft pulleys.

In order not to disrupt the valve timing, before removing the timing belt, it is necessary to set the crankshaft and camshafts to the TDC (top dead center) position of the compression stroke of the 1st cylinder.

To turn the crankshaft, screw the bolt of the accessory drive pulley into place, installing a spacer (bushing or set of washers) between the bolt washer and the shaft end.

Attention! From this stage on, the work can be done in two ways.

• The first method is "academic", accompanied by the manufacture of a device, the need to purchase two plugs for holes in the cylinder head, removed by the destructive method.
• The second method is "popular", which allows to carry out work with minimal labor costs, but requires the obligatory presence of an assistant, high thoroughness of the work and subsequent careful verification of the result. A prerequisite for carrying out work in this way is your confidence that no one has disassembled the engine before you, even to a small extent. Then all the details will be installed in the "factory" positions.

The first way to replace the timing belt of a 16-valve Renault Logan / Sandero engine

To determine the position of the camshafts, it is necessary to remove two rubber-metal plugs from the holes in the left end of the cylinder head.

We remove the resonator of the air path.

In the center of the plug (rubber array) we pierce a hole with a screwdriver.

Using a screwdriver as a lever, we remove the plug from the hole in the cylinder head.

Similarly, we extract another stub.

We turn the crankshaft clockwise by the bolt securing the accessory drive pulley until the grooves on the ends of the camshafts take a horizontal position (parallel to the plane of the cover and cylinder head connector) and are displaced downward relative to the axes of the camshafts.

To fix the camshafts when replacing the belt, a device should be made from a metal plate 5 mm thick (see sketch).

2267–3_Tex_obslugivanie.indd

Camshaft locking tool.

We install the device in the grooves of the shafts.

To check whether the crankshaft is in the TDC position of the pistons of the 1st and 4th cylinders, a hole with an M 10 thread is provided in the cylinder block, into which a special locating pin with a thread length of 75 mm must be screwed. When the crankshaft is in the TDC position of the pistons of the 1st and 4th cylinders, the finger should rest against the milled area on the crankshaft cheek and block the shaft when trying to turn it clockwise.

Using the "E-14" head, we unscrew the technological plug from the threaded hole in the cylinder block located on the front side of the block, in the area of \u200b\u200bthe 1st cylinder - under the oil pressure alarm sensor (for clarity, it is shown on the removed engine).

The bolt of the upper fastening of the gearbox to the cylinder block can be used as a locating pin (shown on the removed power unit for clarity).

We screw two M10 nuts onto the bolt and lock them so that the length of the threaded part is 75 mm.

The manufactured device - screw the adjusting pin into the threaded hole of the cylinder block.

When the crankshaft is in the TDC position of the pistons of the 1st and 4th cylinders, the locating pin 1 will screw into the hole to the end of its thread and rest against the milled area 2 on the crankshaft cheek (for clarity, it is shown on the dismantled engine and with the oil pan removed).

In this case, the crankshaft cannot be turned clockwise.

If, when screwing in the adjusting pin, you feel that it has rested, and the end of the nut on the finger does not touch the end of the hole boss in the cylinder block (there will be a gap between the nut and the boss), then slightly turn the crankshaft counterclockwise by the pulley mounting bolt. Then we screw the adjusting pin into the block hole to the end (until the ends of the finger nut and the hole boss in the block come into contact) and turn the crankshaft clockwise until the shaft cheek pad stops in the finger.

Having loosened the tightening of the tensioner fastening nut with a key "13", we turn the roller counterclockwise, reducing the tension of the timing belt.

Remove the belt from the tension roller ...

… And then from the pulleys of the coolant pump, crankshaft and camshafts.

When replacing the belt, the tensioner assembly and the idler roller must also be replaced.

We unscrew the nut securing the tensioner and remove it.

Using the Torx T-50 wrench, unscrew the screw that secures the support roller.

Remove the support roller and roller sleeve.

Install the new support roller in reverse order.

When installing a new timing belt with arrows on it, orient it so that the arrows coincide with the direction of movement of the belt (clockwise).

We install the belt on the crankshaft toothed pulleys, coolant pump and camshaft pulleys.

Then we simultaneously put the belt on the tensioner roller and install the device on the stud of the coolant pump housing.

When installing the tensioner, insert the bent end of the bracket into the recess of the coolant pump housing.

We turn the setting pin out of the hole in the cylinder block. We take out the plate from the grooves of the camshafts.

We turn the crankshaft two turns clockwise by the bolt of the accessory drive pulley until the grooves on the ends of the camshafts coincide.

We screw the adjusting pin into the hole in the cylinder block to check the correct installation of the crankshaft in the TDC position of the 1st-4th cylinders. If necessary, repeat the installation of the timing belt.

We unscrew the locating pin from the hole in the cylinder block and install the screw plug in place. Install the removed parts in reverse order.

With light blows of a hammer with a plastic striker, we press new plugs into the holes of the cylinder head.

We carry out further assembly of the engine in the reverse order. Replace the accessory drive pulley mounting bolt with a new one and tighten it to 30 Nm, then turn it by 80 ± 5 °.

The second way to replace the timing belt of a 16-valve Renault Logan / Sandero engine

We remind you that by this moment we have dismantled the crankshaft pulley and there is free access to the entire belt and rollers.

For a bolt with washers or a sleeve, which is screwed into the end of the crankshaft, just as in the first method, we turn the engine crankshaft and, accordingly, the camshafts - to the position shown in the photo below.

Focus on the position of the Renault signs (rhombus). At the same time, the assistant must fix the end of the piston lift in the first or fourth cylinder using a long, thin and, most importantly, clean screwdriver inserted vertically into the spark plug hole of one of the corresponding cylinders.

In this position, we apply marks with bright paint that uniquely determine the relative position of the pulleys.

We no longer turn the crankshaft. Let's move on to marking the flywheel.

In the window of the clutch housing, we apply a mark with a bright helmet on the flywheel and on the edge of the window of the clutch housing.

So we fixed the position of the crankshaft.

This is where some complexity awaits us. The fact is that the camshafts, as soon as they are no longer tied by a belt, spontaneously turn at small angles under the action of the valve springs. For now, we leave them in those positions in which they themselves stopped. In no case do we change the position of the crankshaft. We replace the rollers and, after putting the belt on the camshaft pulleys, ask the assistant to turn the camshafts until the marks on them are precisely aligned.

We remind you that the shafts spontaneously turned only at very small angles.

Moreover, the pulley, which, overcoming the resistance of the springs, must be rotated clockwise (the shaft of the exhaust valves), can be turned with a spanner wrench "18" for the pulley fastening nut. (The nut will work in the direction of tightening, which is not scary.) Another pulley often does not require adjustment, and if one is needed (in the direction of unscrewing the nut), then the pulley can be turned with the simplest device made from a piece of pipe with holes drilled in both walls at one of the ends at a distance of 55-65 mm. Insert M8 bolts of sufficient length into the holes (to increase rigidity, you can fix them with nuts). Having hooked the bolts to the spokes of the pulley, we turn it to the desired angle with a piece of pipe as a lever.

The liter has two versions, one with 8 valves and the other with 16 valves. In technical terms, the engines differ only in the design of the cylinder head and of course in power. Sandero 1.6 8 valves produces 87 hp. (Euro-2) or 82 hp (Euro 5) 16-valve version 102 horsepower.

The eight-valve version of the engine is simpler, since it has only one camshaft, however, it is periodically necessary to adjust the valve clearance. In the 16-valve version, there are hydraulic lifters that provide automatic valve clearance. Both Sandero 1.6 engines are also installed on Renault Logan. We will not talk about the 8-valve power unit, because. Let's focus on 16-valve Renault Sandero 1.6 engine.

Renault Sandero 1.6 16V engine device

The power unit is called K4M, it is an atmospheric gasoline, four-stroke, four-cylinder, in-line, 16-valve, with two overhead camshafts. The order of operation of the cylinders: 1-3-4-2, counting from the flywheel. The power supply system is a distributed fuel injection.

The cylinder block is made of cast iron, the block head is cast from an aluminum alloy. The gas distribution mechanism has two camshafts and 16 valves. Connecting rods - steel, I-section, processed together with caps. The caps are attached to the connecting rods with special bolts and nuts. Piston pin - steel, tubular section. The pin pressed into the upper connecting rod head rotates freely in the piston bosses. The piston is made of aluminum alloy. The piston skirt has a complex shape: in the longitudinal section it is barrel-shaped, in the transverse section it is oval. In the upper part of the piston, there are three grooves for the piston rings. The two upper piston rings are compression rings, and the lower one is oil-filled.

Renault Sandero 1.6 engine cylinder head - aluminum alloy, common to all four cylinders. It is centered on the block with two bushings and secured with ten screws. A non-shrinkable metal gasket is installed between the block and the head. The camshafts are driven by a toothed belt from the crankshaft. A valve train with a hydraulic support that automatically provides clearance-free contact between the camshaft cam and the valve lever roller, compensating for wear on the cam, lever, valve stem end, seat chamfers and valve disc. Spark plugs are centered on each combustion chamber, and the valves are V-shaped. Further photo of the valve mechanism of the Sandero 1.6 engine 16 valves.

• 1 - the Camshaft
• 2 - Candle well
• 3 - Hydro support
• 4 - the valve Lever

The hydraulic supports of the valve levers are installed in the seats of the cylinder head. A hydraulic compensator with a ball check valve is installed inside the hydraulic support housing. Oil into the hydraulic support comes from a line in the cylinder head through a hole in the hydraulic support housing.

Replacing the timing belt Renault Sandero 1.6 (Renault Logan 1.6) 16 valves

Replacing the timing belt in a 16-valve Sandero / Logan engine a rather complicated procedure, so be patient and attentive for its implementation. To begin with, a photo of a 16-valve timing drive for a general understanding of the design and device.

• 1 - crankshaft toothed pulley
• 2 - timing belt
• 3 - tension roller
• 4 - toothed pulley of the camshaft drive of the exhaust valves
• 5 - toothed pulley of the camshaft drive of the intake valves
• 6 - bypass roller
• 7 - toothed pulley of the coolant pump

To replace the timing belt, you need to remove the right support of the power unit, the right mudguard of the engine compartment, by the way, for the convenience of the process, it is advisable to perform work on a pit, overpass or lift. Unscrew the upper timing cover. Then we unscrew the lower timing cover. Using the "18" head, unscrew the crankshaft pulley mounting bolt. Remove the pulley and bottom cover.

In order not to disrupt the valve timing, before removing the timing belt, it is necessary to set the crankshaft and camshafts to the TDC (top dead center) position of the compression stroke of the 1st cylinder. To turn the crankshaft, screw the crankshaft pulley bolt into place, with the help of it we will turn the engine without removing the belt.

To determine the position of the camshafts, it is necessary to remove two rubber-metal plugs from the holes in the left end of the cylinder head. Under the plugs are the ends of the camshafts with special grooves. See the photo

It is necessary to insert a special metal plate into these grooves, which will block the camshafts from turning. The grooves should be horizontal, as in the photo.

Now it is necessary to block the crankshaft of the 16-valve engine from scrolling. For this, a special technological hole with a plug is provided in Sandero or Logan, in the cylinder block under the oil pressure alarm sensor. We unscrew the plug and screw in a bolt suitable for the thread there. The main thing is that the thread of this bolt is at least 75 mm. This bolt also blocks the crankshaft from turning in the TDC position of the pistons of the 1st and 4th cylinders.

After we have blocked the camshafts and crankshaft at TDC of the first cylinder, you can remove the old timing belt and put a new one. Let's say right away that when replacing a belt, it is necessary to change the tension and idler rollers. We loosen the tension roller nut and weaken the belt tension with a special cutter of the appropriate size. Using the same facet, when installing a new timing belt, we tighten the belt. We look at the photo.

After replacing and adjusting the belt tension, do not forget to unscrew the bolt from the cylinder block that kept the crankshaft from rotating, as well as remove the plate that kept the camshafts from rotating. Another important thing, when installing the new Logan / Sandero 1.6 16V timing belt, on which the arrows are applied, we orient it so that the arrows coincide with the direction of movement of the belt. And the belt, like all pulleys, rotates clockwise.

This manual will be useful to many owners of various Renault models. Since the Renault K4M 1.6 16-valve engine with a timing belt is installed on Logan, Sandero, Sandero Stepway, Duster, Megan, Fluence and other models of the French manufacturer.
