The Chevrolet Cruze is one of the best-selling cars produced by the independent division of General Motors, Chevrolet (1911). The model first appeared in the car market in 2008 and, constantly improving, is still being produced.

In general, the range of engines that can be used to power Chevrolet Cruze vehicles is very diverse. However, in Russia, models were initially supplied, equipped only with atmospheric engines F16D4 and F18D4, having a cylinder volume of 1.6 and 1.8 liters, respectively. A little later (2010), a turbocharged power unit A14NET / NEL with a cylinder volume of 1.4 liters was added to them, which comes only with an automatic gearbox and is capable of developing power up to 143 liters. from. In this case, the F16D4 engine (EcoTec series) is considered the base engine of the Chevrolet Cruze.

One of the questions that worries buyers of any car is how the gas distribution mechanism (timing) of the power unit is activated. Cars of the Chevrolet Cruze model range are no exception, on which engines with different timing drive mechanisms can be installed.

Timing drive mechanism

The timing drive is one of the most critical components in an internal combustion engine (ICE). It is with its help that the camshaft of the power unit is activated, the rotational movement of which is transmitted from the crankshaft. In modern automobile engines, a rubber belt or metal chain is used for this.

Belt drive

In naturally-aspirated engines used for Chevrolet Cruze vehicles, the timing camshaft is driven by a rubber belt.

Among the advantages of a belt drive, experts note:

• ease of replacement;
• no additional lubrication;
• lack of noise;

A high-strength rubber belt fits over exposed crankshaft and camshaft gears. For more precise synchronization of their rotation, the inner surface of the belt has teeth, which ensure engagement with the teeth of the gears.

The main disadvantage of a belt drive is a small (compared to a chain) service life, which is no more than 90 thousand km of run. At the same time, it is recommended to replace them every 50 ... 60 thousand km. In addition, during the operation of the car, it is necessary to constantly monitor the condition of the belt surfaces and, if cracks appear, immediately replace it. This will avoid more serious engine damage that could occur if the rubber belt breaks unexpectedly.

Chain drive

In the A14NET / NEL engine, the camshaft is driven by a steel chain.

The advantages of a chain drive include:

• long service life (more than 180,000 km. run);
• strength;
• increased reliability.

As for the disadvantages, the use of a chain drive leads to increased noise and the need to install a number of additional parts (tensioner, damper), with which, during operation, the chain is tensioned and its vibrations are damped. In addition, the chain requires lubrication during operation.

The tensioning of the chain is a complex process and is provided by special tensioning rollers. In this case, the tensioner is paired with a special spring and, in addition, the engine oil pressure is used. The steel toothed chain drives the camshafts by contacting the teeth of the sprockets attached to them. The condition of the chain and its service life largely depend on the pressure of the engine oil in the lubrication system of the power unit. The use of high-quality consumables also has a significant impact on the operation of the timing chain drive.

Which is better: a chain or a belt

It is impossible to unequivocally answer the question which is better - a steel chain or a rubber belt. In practice, both chain and belt drives occur at approximately the same frequency. And if previously the presence of a belt in the timing drive was met with misunderstanding, now the belt drive has begun to dominate over the chain drive.

Important! This is due primarily to the fact that the quality of the drive belts has improved significantly.

For their manufacture, the most modern synthetic materials with high technical characteristics are used. They retain the necessary elasticity, while withstanding severe operating conditions, characterized by high mechanical loads and ambient temperature drops in the range from 45 to + 120 ° C.

Many are attracted by the fact that the service life of the chain is more than double that of a belt drive, but we must not forget that the chain stretches during operation and requires periodic maintenance.

Car owners who choose an internal combustion engine with a timing belt drive believe that it is better to replace the belt several times, since this procedure is much easier and cheaper. It is easy to carry out with your own hands.

Chevrolet Cruze 1.6 engine, 1.8 Chevrolet Cruze 1.4 turbo, belt or chain?

Any Chevrolet Cruze engine provides decent dynamics and smoothness for this vehicle. Initially, Russia offered two gasoline atmospheric Chevrolet Cruze engines of 1.6 and 1.8 liters, later a turbo engine with a working volume of 1.4 liters appeared.

The turbo engine provides quite a lot of power, good torque and at the same time is very economical. It is worth noting that in many countries, the Chevrolet Cruze engine has diesel versions of 1.7 and 2 liters. The power units of the Chevrolet Cruze EcoTec series are 4-cylinder 16-valve motors with two camshafts on top, that is, it is DOHC.

An important question that worries many. Is there a belt or chain in the timing belt of Chevrolet Cruze engines? There is a strong belief that the chain is more reliable and does not need frequent replacement. However, modern belts are also quite reliable today. So let's reveal the big secret in the Chevrolet Cruze engines the timing belt. According to the manufacturer, the belt itself has an increased service life.

Photo of the Chevrolet Cruze engine under the hood.

The base engine for Cruz is a 1.6-liter engine. The most interesting thing is that the sedan and hatchback have a power unit of 109 hp, while the Cruze station wagon has 124 hp. The difference is explained by the fact that the version of the car in the universal body has a large mass and carrying capacity, so the base engine must be more durable. Detailed engine characteristics of the Chevrolet Cruze sedan and hatchback further.

Engine characteristics Cruz Ecotec 1.6 (109 hp)

• Working volume - 1598 cm3
• Power - 109 hp at 6000 rpm
• Maximum speed - 185 (manual transmission) and 177 (automatic transmission) kilometers per hour
• Acceleration to the first hundred - 12.5 (manual transmission) and 13.5 (automatic transmission) seconds
• Combined fuel consumption - 7.3 (manual transmission) and 8.3 (automatic transmission) liters

And the parameters of the station wagon motor.

Engine characteristics Cruze SW 1.6 (124 hp)

• Working volume - 1598 cm3
• Power - 124 HP at 6000 rpm
• Torque - 150 Nm at 4000 rpm
• Maximum speed - 192 (manual transmission) kilometers per hour
• Acceleration to the first hundred - 12.6 (manual transmission) seconds
• Combined fuel consumption - 6.5 (manual transmission) liters

More powerful petrol engine with a working volume of 1.8 liters and 141 hp. provides good dynamics, both on the Cruise sedan and on the station wagon and hatch.

Engine characteristics Chevrolet Cruze Ecotec 1.8 liter

• Working volume - 1796 cm3
• Power - 141 HP at 6000 rpm
• Torque - 176 Nm at 3800 rpm
• Maximum speed - 200 (manual transmission) and 190 (automatic transmission) kilometers per hour
• Acceleration to the first hundred - 11 (manual transmission) and 11.5 (automatic transmission) seconds
• Combined fuel consumption - 6.8 (manual transmission) and 7.8 (automatic transmission) liters

Well, the most interesting engine is a turbo engine with a volume of only 1.4 liters. The small volume ensures minimum fuel consumption. At the same time, the presence of a turbine makes the power unit very dynamic. At 140 horsepower, the torque is 200 Nm, recall the atmospheric 1.8 produces 141 horses, but the torque is only 176 Nm, plus increased fuel consumption. At the same time, all the torque of the turbocharged engine is available already from 1,850 engine rpm, and the aspirated 1.8 will have to be turned up to 3800. That is, already at the bottom 1.4 turbo is ready to give maximum. In addition to efficiency (5.7 liters on the highway), the Chevrolet Cruze turbo engine is also more environmentally friendly. Here are the characteristics of this motor.

Ecotec 1.4 Turbo engine specifications

• Working volume - 1398 cm3
• Power - 140 HP at 4900 rpm
• Torque - 200 Nm at 1850 rpm
• Maximum speed - 200 (automatic transmission) kilometers per hour
• Acceleration to the first hundred - 10.3 (automatic transmission) seconds
• Combined fuel consumption - 5.7 (automatic transmission) liters

The Ecotec 1.4 Turbo engine is offered with the Chevrolet Cruze automatic transmission only.

Engine characteristics

Several different powertrains were installed on the Chevrolet Cruze. They differ in technical characteristics, this allows you to choose a car based on the requirements of a particular driver. For convenience, we have summarized all the main indicators in a table.

As you can see, technically, all motors are quite diverse, this makes it possible to choose the most suitable options for the motorist.

At the moment, in accordance with the law, there is no need to check the number of the power plant when registering a car. But, sometimes it is still required, for example, when selecting certain types of parts. All engine models have a number stamped on the ebb of the cylinder head. You can see it directly above the oil filter. Please note that it is prone to corrosion. This can destroy the lettering. To avoid this, periodically inspect the site, clean it from rust, and lubricate with any grease.

Service

To begin with, it is worth considering the scheduled maintenance of the internal combustion engine. This is a mandatory procedure to ensure proper engine operation. According to the manufacturer's recommendations, the minimum mileage between base maintenance is 15 thousand kilometers. But, in practice, it is better to do it every 10 thousand, after all, the operating conditions usually differ from ideal for the worse.

During basic maintenance, a visual inspection of all engine elements is performed. Computer diagnostics are also mandatory. If breakdowns are detected, they are eliminated. Also, be sure to replace the engine oil and filter. The following greases can be used for replacement.

To ensure the smooth operation of the ignition, the spark plugs are changed every 30 thousand kilometers. If they are of high quality, then they serve all this time without any problems and failures.

The timing always requires increased attention. All motors except M13A use belt drive. They replace it on the run of 60 thousand, but sometimes it may be required earlier. To avoid trouble, you should check the condition of the belt regularly.

The M13A uses a timing chain drive. It is more reliable when used correctly. As a rule, replacement is required after 150-200 thousand kilometers. Since by that time the engine is already quite worn out, the replacement of the timing drive is combined with a major overhaul of the power unit.

Typical faults

Any motor has its own shortcomings and malfunctions characteristic of it. This must be taken into account and the problems that arise should be resolved in a timely manner. Let's look at what difficulties may lie in wait for the owners of the Chevrolet Cruze.

The main disadvantage of the A14NET is the insufficiently powerful turbine, it is also demanding on oil. If you fill it with low quality grease, the risk of failure increases. Also, do not constantly drive this engine at high speeds, this will also lead to the premature "death" of the turbine and possibly piston. There is also a problem, characteristic of all Opel engines, with leaking grease from under the valve cover. The pump bearing fails quite often, it is worth replacing it.

On the Z18XER engine, the phase regulator sometimes fails, in which case the engine starts to rattle like a diesel engine. It is solved by replacing the solenoid valve, which is installed in the phase regulator, you can try to clean it from contamination. Another problematic unit here is the thermostat, it lasts no longer than 80 thousand kilometers, but in practice it often fails much earlier.

The problem of the F18D4 engine is the rapid wear of the main elements of the unit. Therefore, it has a relatively short service life. At the same time, there are practically no minor breakdowns.

Considering the F16D3 power unit, one can generally note its reliability. But, at the same time, problems may arise with the failure of the hydraulic valve lifters, they fail quite often. The engine also has a separate exhaust control system. This unit also tends to fail regularly.

The most reliable is the M13A. This engine has a large margin of survivability, which saves the driver from many problems. If you take care of it properly, there are practically no breakdowns. Sometimes there may be a problem with the crankshaft position sensor, this is probably the most common malfunction of this motor. Also, when using low-quality fuel, the check lights up and an error occurs in the power system malfunction.

Tuning

Many drivers do not like the standard characteristics of the engines, so many ways have been invented that help increase power or improve other engine performance. We will analyze the most suitable for each specific power unit.

For the A14NET engine, chip tuning is the optimal solution. Here it is most effective, as a turbine is used. With the correct flashing of the control unit, you can get a 10-20% increase in power. It makes no sense to make other improvements on this motor, the increase will be small, and the costs are significant.

There are much more opportunities for improving the Z18XER motor, but here you need to remember that most of the work will cost a lot. The simplest option is chip tuning, with which you can add about 10% power to the motor. If you want to get a more significant increase, you will need to install a turbine, as well as replace the connecting rod-piston group, at the same time the cylinders are bored. This approach makes it possible to obtain power up to 200 hp. In this case, you will need to put another gearbox, strengthen the brakes and suspension.

The F18D4 usually requires a fairly large investment in tuning, and the results will be very controversial. Even chip tuning has no effect here, to achieve an increase of 15%, you will need to replace the standard exhaust pants with a "spider". For a greater effect, it is worth looking towards the turbine, it gives the greatest increase in power. But, in addition to this, it is desirable to install new parts of the connecting rod-piston group that are resistant to such loads. Otherwise, the engine will have to be overhauled very often.

The F16D3 motor is mainly accelerated by cylinder bore. This allows you to achieve increased power at a minimum cost. At the same time, chip tuning is also required.

M13A is most often overclocked using chip tuning, but this does not give the desired power increase, usually no more than 10 hp. It is more efficient to use short connecting rods, this gives a significant increase in engine volume, and, accordingly, more power is obtained. This option is the most effective, but you have to pay for it with increased fuel consumption.

SWAPO

One of the popular tuning methods is SWAPO, that is, a complete replacement of the engine. In practice, such a refinement is complicated by the need to select an engine that fits the mountings, as well as fitting some standard units to the motor. More powerful options are usually installed.

In fact, such work is practically not carried out on the Chevrolet Cruze, the reason is the small number of suitable power units. Most often, the z20let or 2.3 V5 AGZ is installed. These motors require practically no modifications, while they are quite powerful and reliable.

Forum: Chevrolet Cruze Sedan (2008-2015)

Hello everyone!
Over the past 3 years, I managed to ride on Cruises with all types of engines and transmissions (except for diesel and turbocharged engines)
1600 automatic
This was my first acquaintance - the dealer was taking a test drive. Externally and internally, I liked the car very much, but in terms of driving characteristics - nowhere at all. I could hardly pull, in order to accelerate it was necessary to re-gas. the on-board computer had about 15 liters of average consumption per 100 km. in general, a 1.6 automatic - I do not advise anyone. People buy, and then the sites are filled with ads for the sale of such machines.
1600 mechanics.
A friend had one. Get behind the wheel, it is quite acceptable if you drive calmly. Of course traction is not enough, but the city is the most it. Although the price of 1.6 mechanics is lower, a friend complained about the average consumption.
1800 automatic
I visited it, skated 5 t.km in 8 months. Rides, pulls, but instant acceleration (overtaking, sudden changes of lane, etc., etc.) - does not like, the machine does not have time, a few seconds of ideas, the roar of the engine when switching to low, and Cruz flew.
Consumption on the highway 8.5, in the city consumption 12-13 liters per 100 km.
Pros: automatic - convenience in the city, low fuel consumption on the highway; tiptronic.
Cons: thoughtfulness during overclocking, long downshifts; high consumption; low reliability - several friends complained about breakdowns, which the dealer still admitted.
1800 mechanics.
This is the engine and the box that this car needs. Everything else presented in Russia is just disadvantages. I have owned such a Cruise for more than two years, I still am not overjoyed! I can't say anything negative. Just go for it, at any moment you are driving a car, and not a machine gun trying to adjust to the desired pace. The handle does not bother driving in traffic jams - probably such a car that it is even pleasant to drive in traffic jams.
Average consumption (mainly in the city) - 9-9.5 liters. per 100 km.
I have the LS equipment - the difference from the maximum speed is only the lack of climate control (in principle, not needed) and cruise control (also a useless thing: if you drive a little on the trails, you don't need it, if you do a lot, it's better to go yourself, less likely to fall asleep).
I am completely satisfied with the car, my Kuzya never let me down. A friend who sold his Cruz a year ago is still licking his lips at mine.
Comfortable beautiful salon, everything you need is at hand, nothing superfluous. The trunk is huge, it fits everything you need. My wife really likes the car, the whole family does not have tea.
Who doubts: Cruz or something else, I advise everyone: definitely Cruz. Only advice: do not take the 1.6 engine, you will regret it, it is better to pay a little extra and immediately buy a normal configuration

Essence of the question: what timing mechanism is installed on the Chevrolet Aveo?

Hello. I choose Aveo for myself now after restyling, many haut, but I like this non-standard design. Heard that there is a chain? Is it true? Which of the Aveo engines is the chain on?

In your case, there will only be a belt. Chains were put on the past generation.

Motor without chain.

On an aspirated volume of 1.2 liters of 16 valves on the Chevrolet Aveo, a chain gas distribution mechanism is installed. But such an engine was on the previous generation of cars.

Timing chain engine 1.2 16 valves.

Change the chain after the vehicle has passed 150,000 kilometers ... In most cases, the chain can not only be changed, but also tightened, which cannot be done with a belt that must be completely replaced.

Chain resource

The chain life can depend on many factors.

Including from the operating conditions of the engine. In general, the reviews of the owners confirm this, the timing chain can go through the order 200,000 kilometers without repair.

For this reason, many believe that a chain is more reliable than a belt. But the belts themselves on the latest Aveo models are distinguished by their reliability and quality. They can easily rotate two camshafts (85 kW and 115 hp engine) and sixteen valves. Also, such motors are distinguished by an improved gas distribution system and economy.

Which is better to choose: a chain or a timing belt?

Timing belt on the Chevrolet Aveo.

Replacing a timing chain or belt is a rather complicated procedure that requires certain skills, and therefore it should only be trusted by professionals at a service station.

It should be noted that the condition of the chain and its resource will largely depend on the oil pressure in the engine, its condition and quality. If you follow certain operating conditions that are spelled out in the manual for the car, then the chain can last long enough. It is also important to use quality consumables and oils.

Timing belt on a 1.4 liter engine.

A modern car can clearly independently track all changes that occur in the timing belt, and also signal this to the driver with a message on the instrument panel.

Overview of the chain motor on the Chevrolet Aveo

conclusions

If the machine is repaired and maintained in a timely manner, as a result of which all timing parts are changed on time, this will help to avoid costly repairs of the entire engine, which can be caused by damage to the timing chain or belt.

The surface of the toothed part of the belt should not have cracks, undercuts of teeth and peeling of the fabric from the rubber, and the reverse side of the belt should not have wear, exposing the cords, and traces of burning. The end surfaces of the belt should not be delaminated or frayed. If damaged, the belt must be replaced. The belt must also be replaced if traces of oil are found on it (before replacing the belt, the cause of oiling should be eliminated) or when replacing a failed belt tensioner or guide roller.

Upon reaching a mileage of 150 thousand km, the belt must be replaced regardless of its condition.

We carry out the work with an assistant on a viewing ditch or overpass.

We start by removing the protection of the power unit.

From the bottom of the car with the head "13" we unscrew the four bolts securing the protection of the power unit to the subframe of the front suspension.

We remove the protection of the power unit, supporting it with an adjustable stop.

We take out two pistons that simultaneously connect the flap and the right wheel fender.

Using the "8" head, turn off the three self-tapping screws for attaching the shield to the subframe.

Sliding the right flap down, we take it out from under the wheel arch liner and remove it.

We unscrew the self-tapping screws for fastening the fender liner of the right front wheel to the front bumper and fender and take out the clips for attaching the front part of the fender liner to the body, bend the front part of the fender liner and put it behind the brake disc.

To check the condition of the belt with the E-10 head, unscrew the two screws securing the upper timing cover.

Remove the cover.

Turning the crankshaft with the E-18 head clockwise by the screw securing the accessory drive pulley, ..

… Evaluate the condition of the timing belt.

The operation to replace the timing belt is quite complicated. At authorized dealer services, when replacing the belt, a special tool and devices are used to set the engine timing. Therefore, we recommend that you only replace the belt yourself by an experienced contractor who has the appropriate skills to repair modern engines.

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

To access the timing belt, dismantle the right support of the power unit.

We install a height-adjustable stop through a wooden block under the engine oil pan.

Remove the air filter.

Using the “15” head, we unscrew the two bolts securing the right support of the power unit to the side member, three bolts securing the support to the engine bracket and the nut securing the support to the mudguard of the body.

We take out the support from the engine compartment.

Right support of the power unit.

To access the ends of the camshafts, remove the cylinder head cover.

Pulling upwards, remove the covers for the wiring harness of the engine management system from the cylinder head cover holders.

We move the spring clip of the crankcase ventilation tube tip.

Remove the tube tip from the cylinder head cover fitting.

Using the E-10 head, unscrew the 11 screws securing the cylinder head cover.

Remove the cylinder head cover.

For clarity, we show further operations on a dismantled engine.

Before removing the belt, we set the crankshaft and camshafts to TDC (top dead center) of the compression stroke of the first cylinder.

To do this, turn the crankshaft clockwise by the screw securing the accessory drive pulley until the mark on the accessory drive pulley coincides with the mark on the lower timing cover.

In this case, the grooves made on the shanks of both camshafts should be located parallel and practically at the same level with the surface of the cylinder head, adjacent to the head cover.

If the grooves on the camshaft shanks do not occupy the indicated position, turn the crankshaft one more revolution (360º) clockwise and again check the correct installation of the crankshaft and camshafts.

Using the E-18 head, unscrew the screw that secures the accessory drive pulley. In order to keep the crankshaft from turning, we put stops under the wheels of the car, turn on the fifth gear in the gearbox and ask the assistant to firmly press and hold the brake pedal.

If it was not possible to unscrew the pulley fastening screw in this way, then, by unscrewing the two bolts with the head "15", dismantle the dirt-protection plate covering the gap at the junction of the gearbox housing and the engine oil pan - next to the housing of the inner hinge of the right wheel drive.

We insert a slotted screwdriver through the gap between the flywheel teeth and rest it on the differential bearing cover, thereby blocking the crankshaft from turning.

Having unscrewed, we take out the screw securing the auxiliary drive pulley.

Remove the pulley.

Using the "15" head, unscrew the three bolts securing the bracket for the right support of the power unit (the coolant pump pulley has been removed for clarity).

Remove the bracket.

Using a slotted screwdriver, release the retainer of the middle timing cover on one side ...

... and on the other hand.

Lift and remove the middle timing cover.

Using the E-10 head with an extension cord, unscrew the four screws securing the lower timing cover.

Remove the cover .

We again check the correctness of the engine camshaft timing.

With the accessory drive pulley removed, check the coincidence of the mark on the crankshaft toothed pulley with the mark on the cylinder block cover.

The marks on the toothed pulleys of both camshafts must be opposite each other.

If necessary, turn the crankshaft to the required position using the screw for securing the accessory pulley, screwed into place through a suitable thrust bushing.

In order to secure the camshafts from turning when replacing the belt, it is necessary to make a device from a metal plate or angle.

2290-6_Dvigatel.indd

Camshaft locking tool.

We insert the device into the grooves on the camshaft shanks.

The plate will fix the shafts relative to each other.

Attention! To avoid damage to the drive discs of the camshaft position sensors, install the plate so that it does not touch the discs. For this, two recesses are made in the plate.

To loosen the belt tension, insert the “6” hexagon into the roller hole and, turning the roller clockwise with the hexagon, release the belt tension and pull the belt off the roller.

Remove the timing belt from the camshaft and crankshaft toothed pulleys.

Timing belt, number of teeth 146, width 24 mm.

Caution: After removing the belt, the crankshaft must not be turned to avoid the valves sticking into the pistons.

If it is necessary to replace the tension roller with a Torx T-50 wrench, unscrew the screw that secures it.

We shoot the video.

To replace the belt guide roller with a Torx T-50 wrench, unscrew the roller fastening screw.

We shoot the video.

When installing the tension roller, we introduce the protruding end of its spring (on the reverse side of the roller) ...

… Into the corresponding groove on the cylinder block cover.

Before installing the belt, check by the coincidence of the alignment marks (see above) that the crankshaft and the camshaft actuator housings of the phase control system are installed correctly. If necessary, turn the crankshaft and camshaft pulleys to the desired position. We put the belt on the toothed pulleys of the crankshaft and camshafts and wind the belt behind the guide roller. Turning the tension roller clockwise, start the belt for it and release the roller. This will automatically tighten the belt.

We take out the fixing device from the grooves of the camshaft shanks. We turn the crankshaft two turns clockwise for the screw securing the accessory drive pulley.

We again check the valve timing. If the timing marks do not match, we repeat the procedure for installing the timing belt.

Tighten the screw securing the accessory drive pulley first to a torque of 95Nm. Next, turn it 30 °, and then another 15 °.

All other parts and assemblies are installed in the reverse order.
