The Renault K7M 1.6 8V engine is used for installation on Renault Logan 1.6 8V (Renault Logan), Renault Sandero 1.6 8V (Renault Sandero), Renault Clio 1.6 8V (Renault Clio), Renault Symbol 1.6 (Renault Symbol).
Features. The Renault K7M 1.6 engine does not differ structurally from, all the difference is in the volume increased to 1.6 liters. The increase in volume was achieved by increasing the radius of the crankshaft crank (other dimensions are the same), the piston stroke as a result increased from 70 mm to 80.5 mm. The cylinder block height has increased, but all geometric parameters are identical to the K7J. The Renault K7M and K7J engines have the same cylinder head and connecting rods. Engine resource - 400 thousand km.
On the basis of the K7M engine, a motor with a 16 valve cylinder head was created. This engine has more advanced characteristics and technologies.

Service

Oil change for Renault K7M 1.6 engine. It is necessary to change the oil on Renault Logan, Sandero, Clio, Symbol cars with the Renault K7M 1.6 engine once every 15,000 km or a year of operation. With intensive engine wear conditions (driving in city traffic jams, working in a taxi, etc.), it is advisable to change the oil every 7-8 thousand km.
What oil to pour into the engine: type 5W-40, 5W-30, Renault-approved Elf Excellium 5W40 oil filled from the factory.
How much oil to pour: when replacing with a filter, 3.4 liters of oil are required, without replacing the oil filter - 3.1 liters.
Original engine oil filter: 7700274177 or 8200768913 (both filters are interchangeable).
Replacing the timing belt needed every 60 thousand km. Do not postpone this procedure, if the timing belt breaks, the valve bends. Replacing the timing belt can be combined with adjusting the valves (there are no hydraulic lifters on Renault 1.6 8V).
Air filter must be replaced every 30 thousand kilometers or 2 years of operation. In dusty conditions, it is recommended to replace the air filter more often.

Hello everyone! After reading this article, you will learn how the oil is changed in a Renault Logan 1.4 and 1.6 liter engine.

It's no secret that a timely replacement of engine oil significantly extends the engine's life. The fact is that special additives are added to engine oils, which lose their properties over time. And if you do not change the oil for a long time to a new one, then the engine wear will increase, which will damage it much faster. In this article, we will talk about the correct oil change in the engine. So let's get started.

The frequency of oil change in the Renault Logan engine is 15,000 km or 1 year, whichever comes first. However, it should be understood that weather conditions and fuel quality in our country leave much to be desired. Therefore, it is better to reduce the replacement interval to at least 10 thousand km, or even better to 7.

Oil change in Renault Logan engine - what to fill?

Thank God that now is no longer Soviet times and there is no deficiency with motor oils. Come to the store and choose what your heart desires. You want Liquid Moli, you want Mobile, you want Lukoil ... And so you can go on for a very long time. I didn't have enough fingers and toes to list all the brands of oils that are available in modern car oil stores. And there are also all sorts of inscriptions like 5W40, 5W30, 10W40, etc ... Synthetics, semi-synthetics ... The head is spinning. The common man does not always fully understand these designations. Let's figure it out together.

According to Renault, this is the best choice. If your car is not under warranty, then you can use any brand of engine oil, but with a viscosity of 5W40 all year round, or 10W40 in the summer, and use less viscous motor oils in winter. According to the API standard, everything is democratic here too. Ordinary semi-synthetics or synthetics (hydrocracking) with a quality class of at least SL are poured into Logan.

For replacement, we need no more than 4 liters of fluid and a new oil filter. By the way, you can additionally use flushing, or you can do without it if the oil was changed in a timely manner.

Oil change in Renault Logan engine - stages of work

First of all, we start the engine and wait until the temperature rises to working temperature. By doing this, we heat up the oil so that it becomes more liquid. When the temperature arrow rapidly crawled up, we turn off the engine and go down under the car.

Of course, it's ideal if you have a hole in your garage ... Or, at least, there is at least a garage!

Usually, the engine protection (armor) on a 1.4l engine has a technological hole for changing the oil in the engine and box. If there is none, as for example on a 1.6l engine, then you will have to remove the protection in order to get close to the engine crankcase. If there is, then we simply unscrew the drain plug, substitute some container and drain the mining. To unscrew the drain plug, we need a tetrahedron.

The next step in changing the oil in a Renault Logan engine is removing the oil filter. You may need an oil filter remover, or you may be able to unscrew it with your hands or improvised means. In general, the main thing is the result. Be careful as some more lubricant will flow out when you unscrew the filter. Keep a waste container handy and avoid scalding. All. Now we are waiting for the oil to drain completely.

We wrap the drain plug in place and tighten with effort. We install a new oil filter, having previously lubricated the sealing ring with fresh oil. Pull the filter out by hand with some effort.

We take a funnel and pour fresh oil into the engine. For a 1.4 engine, a little less than 4 liters of fluid will be required, and for a 1.6 engine, 4.5 liters. Consider this point. The oil level is checked with a dipstick. This is done as follows. First, fill in engine oil up to the maximum mark on the dipstick. After that, close the filler neck and start the engine. Wait until the oil pressure lamp on the dashboard goes out and turn off the engine. Wait 2-5 minutes for the oil to drain into the crankcase. Then check the level again. Ideally, the oil level should be between the minimum and maximum marks. Top up with the required amount of oil if necessary.

After the work done, we remove the leaks of engine oil from the engine and its components and do not forget to write down the mileage at which the replacement was performed. That's all, oil change in the Renault Logan engine can be considered finished. Thanks for reading and don't forget to read our other articles.

Renault Logan 1.4 is a popular car among taxi drivers. The first versions of the Logan are now in strong demand in the aftermarket. It is this fact that confirms that the car is quite reliable and unpretentious to use. Of course, there are many nuances inherent in budget models, but the overall impression from Renault Logan is purely positive. This can be said about the possibility of self-service, but even experienced motorists may have questions here. For example, one of the most common Renault Logan repair procedures is changing the engine oil. But a much more difficult task is the choice of the oil itself, how much to fill it, and how to choose the right one based on the best parameters and brands. In this article, we highlight the best engine oils using the example of Renault Logan with a 1.4-liter engine.

When to add new oil

At first glance, the answer to this question can be obtained by looking at the desired item in the Renault Logan operating instructions. The official regulations for changing the oil for this car are set at around 15 thousand kilometers. On the other hand, oil changes may occur earlier if the vehicle is operated in difficult harsh conditions. For example, if the car often moves on bumpy roads, in light off-road conditions, under the influence of low temperatures, etc. In this case, the replacement schedule is reduced to 10 thousand kilometers. This is a completely optimal indicator at which the engine oil will not have time to lose its useful properties. If the Russian owners follow only the official data (we are talking about 15 thousand km), then there may be problems with the reliability of the internal combustion engine.

How to know when it's time to change the oil

In addition to the official regulations, you can understand the need for an oil change by the following signs:

• the oil stinks burnt
• the oil is dark brown
• oil contains metal shavings
• gears are included with a delay
• high fuel consumption
• the engine is not able to develop maximum speed
• high level of noise and vibration emanating from the internal combustion engine and gearbox

How much oil to fill

The amount of lubricant to be poured depends on the working displacement of the power plant. In our case, we are talking about the basic 1.4-liter 8-valve modification of the Renault Logan. For such a car, it is preferable to fill in 3.3 liters of fluid... Therefore, it will be beneficial to purchase a 4 liter canister. The remaining oil can be topped up gradually every 600-700 kilometers.

Selection of oils by types, parameters and brands

Renault has provided several types of original lubricants especially for Renault Logan. There are three types:

• Synthetic - the most fluid and liquid oil, very resistant to low temperatures. Such a lubricant composition is best suited for Renault Logan with low mileage. The replacement schedule for such an oil is the longest, which is one of the key advantages. In addition, with such an oil, fuel consumption is lower, the engine power is higher and the cooling of the internal combustion engine components is better.
• Mineral is the thickest oil, extremely unsuitable for modern cars. It can only be filled in as a last resort - for example, with high mileage or lack of funds for at least semi-synthetic oil.
• Semi-synthetic oil is an economical option for those who do not want to spend money on expensive synthetics, and at the same time prefer a more modern product than cheap mineral water.

It can be concluded that for Renault Logan with a 1.4-liter engine, synthetics or semi-synthetics will be the best oil.

In addition, viscosity characteristics also influence the choice of oil. So, especially for "Logan" you need to select the viscosity parameters 5W-40 and 5W-30. Original oil for Renault Logan - Elf Evolution SXR. Alternatively, you can pick up an equally high-quality analogue, but only among brands with a good reputation. Of these, Castrol, Mobil, Rosneft, Lukoil, ZIK and others can be distinguished.

Renault Logan in Russia began to be produced in 2005. The creators based the model on the principle of simplicity and unpretentiousness, which corresponds to the corporate concept of "strength and quality". And in many ways (if not all) the idea came true. In 2010, the company offered the market an updated Logan

Renault Logan is sold only with a sedan body. The engine range includes engines of 1.4 (75 hp) and 1.6 liters (84 hp). Both are aggregated with a 5-speed "mechanics", which has long and well proven itself on the Clio and Kangoo models.

It is obvious that a simpler car, both in terms of design and performance, is difficult to imagine today.

Renault Logan Manual

If the 1.4 engine is still rather weak, then the 1.6 eight-valve is enough for the eyes. Particularly pleasing is its high-torque at the bottom.
In fact, Logan has nothing to break under the hood. Still, some troubles do happen.

: 1 - radiator outlet hose; 2 - radiator supply hose; 3 - additional resistor; 4 - fan; 5 - radiator; 6 - fan casing; 7 - thermostat housing; 8 - the outlet pipe of the cylinder head; 9 - steam hose; 10 - coolant temperature sensor; 11 - heater radiator supply hose; 12 - air outlet fitting; 13 - heater radiator outlet hose; 14 - expansion tank; 15 - inlet hose; 16 - supply pipe of the coolant pump

Firstly, in winter cold the gas pedal can suddenly stick. And it's not that she will stay on the floor - there is no such thing; but the revolutions, especially after opening the throttle to full, refuse to fall below 2-3 thousand revolutions.

According to Renault servicemen, the accelerator is likely to stick either due to a poorly lying mat, or due to the fact that the cable sheath is deformed into a strong minus. In the first case, it is recommended to change the rugs, but in the second - to lubricate the cable. They say it helps ... Secondly, at a run of 10-15 thousand, the engine may start to malfunction - symptoms of "triple formation" appear. But after reaching the operating temperature, everything returns to normal. As a rule, the culprit is either the electrical connector of the crankshaft position sensor (contact repair is a quick and inexpensive procedure), or spark plugs. In fact, this is only a consequence. And the reason is poor quality gasoline.

However, candles are still half the trouble: on TO1 they are still changed without fail. Troubles also happen. For example, the "demise" of the camshaft oil seal, which, by the way, can happen with almost any run.

At 30-40 thousand km, a pump is capable of causing trouble. A characteristic whistle will be a sure signal that it is time to replace it. The cooling system pump changes with such a run under warranty, together with a roller and two drive belts.

TransmissionRenault Logan

: 1 - differential side gear shaft; 2 - clutch housing; 3 - primary shaft; 4 - a dustproof cover; 5 - gear shifting mechanism; 6 - clutch release drive plug; 7 - holder for wiring harnesses; 8 - clutch release cable sheath bracket; 9 - back cover; 10 - breather hose fitting; 11 - hole for the vehicle speed sensor; 12 - housing of the inner hinge of the left wheel drive; 13 - reverse light switch; 14 - gearbox housing; 15 - oil filler plug

On Renault Logan a very elderly 5-speed manual gearbox is installed. And this is just its essential plus: the box is very reliable, unpretentious and durable. Nevertheless, Logan owners have operational questions every now and then. So, one of the popular complaints is the crunch when reverse gear is engaged. However, it should be remembered that the box of this machine is devoid of a reverse gear synchronizer. To eliminate an unpleasant sound when turning on, you need to take a short pause after pressing the clutch. That's all.

A more significant problem is the noise of the gearbox, especially in a hot state, after 50-100 km of run. You can evaluate it by squeezing and releasing the clutch several times. In general, except for discomfort, noise is not fraught with anything. According to Renault specialists, it is possible to cope with it for a while by changing the oil in the gearbox. For the sake of objectivity, we note that there have been cases of warranty repair of boxes.
In addition, the service statistics are familiar with the facts of premature failure of the release bearing. However, we emphasize that this is more the exception than the rule.

The clutch is guaranteed to nurture more than 100 thousand km of run and change assembly.

: 1 - stretcher; 2 - suspension arm with silent blocks and ball joint; 3 - steering knuckle with hub and bearing; 4 - shock absorber rack; 5 - bar of the anti-roll bar

: 1 - bracket for attaching the beam arm to the body; 2 - beam; 3 - arm bracket; 4 - beam lever; 5 - shock absorber; 6 - compression stroke buffer; 7 - pillows and washers of the upper fastening of the shock absorber to the body; 8 - bolt fastening the shock absorber to the lever; 9 - bottom spring gasket; 10 - spring; 11 - upper spring gasket; 12 - rear wheel brake mechanism; 13 - rear wheel trunnion; 14 - brake drum assembly with rear wheel bearing; 15 - cap; 16 - wheel bearing nut; 17 - silent block of the beam lever; 18 - bolt and nut for fastening the beam lever to the bracket

In general, neither the suspension, nor the steering, nor the braking system cause serious complaints. But, as with other Renault Logan units, there is always a place for little things. The front hub bearings should be recognized as not the strongest link: quite often they have to be changed already for 30 thousand kilometers.

With power steering: 1 - steering wheel: 2 - steering column: 3 - left steering knuckle assembly with a hub; 4 - left tip of the steering rod; 5 - intermediate shaft; 6 - bolts of fastening of the steering gear housing to the subframe; 7 - steering gear housing; 8 - hydraulic booster drain line; 9 - hydraulic booster reservoir; 10 - filling line of the hydraulic booster; 11 - hydraulic booster injection line; 12 - power steering fluid pressure sensor; 13 - power steering pump; 14 - stretcher; 15 - right tip of the steering rod; 16 - right steering knuckle assembly with a hub

There were also cases of complaints about shock absorbers - the warranty replacement reassured the owners. Less often, by 50 thousand km of run, ball joints can knock. Much depends on the operating conditions and driving style.

Steering problems, as a rule, are limited to replacing steering tips for 50-60 thousand km. Otherwise, both the mechanism itself and the power steering serve faithfully.

The braking system works quite reliably, but the "frog" of turning on the stoplights regularly spoils the mood. Often it has to be adjusted at almost every MOT. Agree, though a trifle, but rather unpleasant.
As for the brake pads, the service life of the front ones can vary from 25 to 40 thousand kilometers, depending on the driving style. Discs are usually replaced with every second pad change. Rear pads and drums last twice as long as
front.

Body and interior

There are several complaints at once. First, the quality of the paintwork leaves much to be desired. However, let's be fair: today it is a common problem, not just Renault.

Secondly, there is poor interior ventilation. Complaints that in bad weather it is necessary to lower the glass almost completely for the sake of elementary visibility are by no means a rarity. In winter, there were cases when the seal froze to the door, broke when opened, after which it began to siphon in the cabin.

The native wiper blades are of very poor quality. Often they have to be replaced before the first maintenance.
Finally, according to statistics, a lot of complaints are caused by the noisy operation of the air conditioner ..

Essence of the question: How much oil to pour into the engine on Renault Logan?

Please tell me how much oil to fill in an 8-valve engine with a volume of 1.6 liters? Because different meanings are written everywhere, I would like to know for sure !?

The following two tabs change content below.

I own a Renault Megan 2 car, before that there were Citroens and Peugeots. I work in the service area of \u200b\u200ba dealership, so I know the car's structure "inside and out." You can always ask me for advice.

If you recently became the proud owner of Renault Logan, then sooner or later you will think about the question of when to change the oil in the car. And here you can refer to the operating instructions for your car, or read this manual to the end.

Filling volumes for 3 Renault Logan engines

As you know, Renault Logan was produced in three different engine options:

K7J - 1.4 liters with 8 valves.

K7M - 1.6 liters with 8 valves.

K4M - 1.6 liters with 16 valves.

Thus, for two types of engines with 8 valves, 3.4 litersoil, and for a 16-valve brother, whole 4.8 liters... All this is due to the fact that the working volume of the "head" with 16 valves is much larger, and, consequently, the need for lubrication of all working elements and parts becomes higher. it's up to you, the 16-valve is more whimsical, but also more dynamic.

Engine oil selection

You can read about which oil is better to fill in, you can read more about oil filters and the procedure for changing oil on Renault Logan in
