Gasoline engine Nissan Qashqai 2.0 liters of the MR20DE series can be found not only on Nissan models, but also on Renault vehicles under the M4R designation. The power of the gasoline aspirated varies from 133 to 147 hp. depending on the settings. The motor is quite modern, its development was completed in 2005. The engine is assembled mainly in Japan. 
The device of the Qashqai 2.0 liter engine.
The inline 4-cylinder 16-valve gasoline engine has an aluminum cylinder block. Timing chain drive, there is a variable valve timing system with a phase shifter on the intake camshaft. There are no hydraulic compensators in the cylinder head. It is necessary to adjust the valves manually by selecting pushers-washers of different thicknesses.
Nissan Qashqai 2.0 Engine Cylinder Head
Nissan Qashqai block head made of aluminum alloy. Two camshafts rotate in the bearing housing, which press with their cams directly on the valves through special pushers. The camshafts are not attached with separate covers, but with a common pastel. Candle wells have very thin walls, an overabundance of force when tightening the candles leads to cracks in the cylinder head. The mechanism for changing the phases of the gas distribution on the intake shaft is implemented using hydraulic system... The increase in pressure causes an increase in the deviation of the camshaft from the nominal position relative to the valve axes. The oil pressure level is controlled by a solenoid valve controlled by the electronics of the Nissan Qashqai engine.
Timing drive of the Nissan Qashqai 2.0 engine
Timing drive Nissan Qashqai 2.0 chain... There are two chains. One bigger size rotates the camshaft sprockets, the second small sprocket of the oil pump. With intensive use, the chain begins to stretch after 100,000 runs. This leads to a phase shift that even the automation that controls the phase shifter cannot correct. The timing diagram is further in the photo.

Replacement timing chains on Nissan Qashqai
Chain The timing belt rotates the engine shafts, whereby air is mixed with fuel in the right proportion and enters power unit vehicle, and the exhaust gases in this case are removed with its use. The operation of the gas distribution mechanism directly affects the performance of the engine, therefore, its condition must be carefully monitored and, if the slightest sign of malfunction is detected, solved. When chain in other words, the timing belt breaks, then expensive car repairs are inevitable.
Features of the chain mechanism on the Nissan Qashqai
Timing for Nissan Qashqai with engine displacements of 1.5 and 2.0 liters, in addition to other petrol chain-type units, although the gas distribution system Nissan Qashqai 1.6 l, which uses diesel for fuel, has a timing belt.
Replacement chain mechanism Nissan Qashqai 3.5.0 l, 1.3.2 l, 1.5 l should be performed according to the regulations every 150-200 thousand km of run, and the belt on 1.6 l diesel engines should be changed after the same time interval.
The chain mechanism is more reliable and durable in comparison with the belt, and, you, you have to change it less often than is usually indicated in the manual. For the most part, it effectively fulfills its purpose even after 150 thousand km and can serve up to 250-300 thousand km without any complaints.

However, in contrast to the belt, the chain system contributes to a higher noise level during the operation of the motor, in addition, it is more difficult to work when changing this element.
How to replace the chain of the mechanism
When working with the timing chain, Nissan Qashqai 2l differently others gasoline engines performed at home, you need to follow the following sequence of actions:
- Remove the right front wheel.
Attention! It is important to carry out the full range of work with a cold engine!

The next step is to install new part gas distribution mechanism.
Conclusion
Replacing the timing belt, which is installed on diesel versions of the car Nissan Qashqai, is produced in a similar way. If the owner is not sure of his competence, then it is better to entrust the repairs to replace the timing chain Nissan Qashqai 4.5.0 l and other engine modifications to professionals. The quality of the belt installation, in other words, the chain depends on how long the engine will last without damage and complex repairs.
The lion's share of cars on the "secondary" are 5-seater "cats" - so affectionately call their pets by the participants of Internet forums. And if you look properly, you can even come across "Qashqai + 2", which, due to the elongated base and a pair of seats in the trunk, allows you to take on board additional passengers (small, however, in stature) or a couple of extra suitcases.
The choice of engines is small: there are only two. The basic "Qashqai" with a 1.6-liter engine has front-wheel drive and, until recently, was equipped exclusively mechanical box... The two-liter version with a 140-horsepower unit is produced both with a front and a plug-in four-wheel drive... In addition, two liters suggested a choice between the "mechanics" and the variator.
The configurations of "Kashkaya", like all other "Nissans", are strictly fixed. Air conditioning, power accessories, ABS and 6 airbags are included in any version, and in the top one you can even find such delights as leather upholstery, panoramic roof, xenon headlights and navigation.
The price plug for a three-year-old car ranges from 550 to 850 thousand rubles. If we compare these figures with the prices for new cars in 2009, it turns out that Qashqai has fallen in price by only 15–20% in three years - that is, Nissan turns out to be very liquid, which cannot but rejoice.
Body and electrical equipment
Little troubles
Buying a three-year "Qashqai", you don't have to worry about the quality of the body. Even on the very first copies that set foot on our land five years ago, it will not be possible to detect rust - the only exceptions are cars that have been in an accident. A layer of paint reliably covers the metal from an aggressive environment.
In some cases, drivers notice that they start tapping trunk lid... Such a nuisance is observed both on the regular and on the extended version. This ailment is treated with a simple adjustment, but we advise not to pull with this procedure: if the door is not adjusted in time, it can damage lock... Other little things worth noting brake pedal creak, which is solved by simple lubrication - this is generally a penny problem.
The second owner shouldn't have much trouble in terms of electrics. All troubles, as a rule, provoke optional equipment , which is installed on "gray" car services by not too qualified craftsmen.
Transmission
Do not slip!
With correct and competent operation, the "Kashkaya" transmission does not cause any problems. Clutch generally reliable: the average service life on machines with "mechanics" is usually 100,000-150,000 km. You can kill him earlier only if you constantly abuse the slip - this is typical of inexperienced drivers. In theory, it is possible to change a burnt clutch separately - a box, a basket and release bearing- but in practice dealers change the assembly.
Variable speed drive he also keeps a stiff upper lip, and if he is not tested for strength, furrowing the mud, then he will hold out 200,000 km or more. But replacing it, if something happens, will cost a pretty penny: a new unit costs more than 200 thousand rubles. So take care of the transmission from your youth.
Engine
Centenarians
Representatives of the branded service cannot say anything bad about motors. Both the 1.6-liter power unit and its more powerful counterpart can be safely called centenarians. The very first "Qashqai" cars sold in our country have already managed to run more than 200,000 km, avoiding any serious problems. Here we must pay tribute to the dealers who are extremely sensitive to the passage Maintenance... They do not allow customers to pour their oil and bring in spare parts bought on the side, even if they are original ones. Recently, the deadline for the mandatory replacement of candles has been tightened. If earlier they were forcibly changed every 30,000 km, now the term has been reduced to 15,000 - that is, at each MOT, regardless of the state.
Valve train chain change not according to the regulations, but according to the state: the need for replacement happens to 150,000 km. Drive belt attachments requires replacement on average every 100,000 km.
Of the minor troubles that await the owners of a 1.6-liter engine, it is worth noting the whistle alternator belt... This is due to the ingestion of reagents that are sprinkled on the streets in winter.
Considering offers when looking for a suitable "Kashkaya", you can find cars with diesel engines volume of 1.5 or 2 liters, and all - exclusively on "mechanics". They came to us from Europe and were never officially sold in Russia. Mechanics cannot say anything definite about the reliability of these motors, since diesel modifications very rarely come to the official service. Many of these "Qashqays" are also sold with twisted mileage, so we advise you to avoid such options.
Chassis and steering
Change - so completely
It may seem that "Kashkai" has no chronic diseases. However, alas, this is not the case: a fly in the ointment is still present in the ointment.
Suspension turned out to be the problematic place of "Kashkaya". Shock absorbers rarely live longer than 30,000 km, and their mileage does not depend too much on operating conditions. Therefore, since 2009, the Qashqai began to install parts from the X-Trail. Now the shock absorbers last much longer and can go 75,000-100,000 km without replacement. But only the front-rear still have to be refreshed every 35,000-50,000. The problem is the weak bushings, which do not change separately, only assembled with a shock absorber.
Reliability does not shine and steering rack ... In the early years, there was even a recall campaign. And although the declared service life of the unit is already 350,000 km, on many machines the rail dies already at 100,000 km. the main problem- in the steering rods. The first symptom of an early replacement is a knock on the steering wheel. Technically, it is possible to change the rods separately from the rail, but Nissan prescribes to change the entire assembly.
Pads in front, on average, they walk 30,000 km, and the rear - 45,000-60,000. Brake discs Like many other cars, they last twice as long as pads.
BUYING?
Apart from the individual troubles that the suspension and the variator can cause, the car has no serious flaws. But if you want to continue driving without knowing the problems, we recommend servicing the car at an authorized dealer after the warranty expires. Yes, you will have to put up with not always justified replacements of consumables, but, as you know, you have to pay for a quiet life. Besides official dealers offer a 30% discount on repair work for non-warranty machines.
FUNCTIONAL PURPOSE OF THE TIMING CHAIN
The timing chain drive of the Nissan Qashqai is part of the timing mechanism and is involved in the transmission of torque from the crankshaft to the camshaft. The chain can connect them directly or participate in the work indirectly, for example, connecting the camshafts to each other, if there are two of them, while functional purpose it remains unchanged.
Monitoring the timing chain condition, replacing "dampers" and tensioners, is part of routine vehicle maintenance and plays an important role in engine operation vehicle... It is necessary to monitor the condition of the gas distribution system regularly, as this directly affects the vehicle's power, sensitivity when supplying gas and fuel consumption.
FEATURES OF CHAIN REPLACEMENT
In most engines of old car models, chains with roller links were used to transmit torque, often the components went in two or three rows, this made the timing chain a very reliable, almost eternal mechanism that did not need constant maintenance. Often the car traveled up to 300,000 km. and the chain of the mechanism received only lateral play, and the worst thing that could happen to the gas distribution mechanism was the jumping of the links, breaks were extremely rare. Over time, the trend in the creation of cars has become the production price, efficiency, environmental friendliness and the weight of the car's engine, which affects its power. In these conditions, manufacturers began to strive to replace the timing chain with a lighter, cheaper and easier to maintain timing belt. And those motors, in the design of which the chains were preserved, the roller components were replaced by light plate links, more reliable than timing belts, but still not as strong as roller chains.
The Nissan Qashqai timing chain has a number of features that fundamentally distinguish it from the timing belt.
1. The chain is a durable mechanism, its wear takes much longer than the timing belt, breaks occur, but much less often than in belt-driven engines.
2. An open circuit of the gas distribution mechanism occurs quite rarely, and therefore an engine breakdown, which requires an expensive overhaul, does not occur often.
3. Timing chains are quite noisy, but with the current level of car sound insulation, this parameter becomes not very important.
4. When the chain is worn out, its backlash and lateral runout occur, this indicates the need to replace the old chain with a new one. Since the metal part is sagging and lateral beating is accompanied by strong noise, it is simply impossible not to notice and not attach importance to it. The noise under the hood will be the first "call" indicating the need for vehicle maintenance.
5. The main disadvantage of replacing the timing chain of the Nissan Qashqai is that it is located inside the cylinder block and it is rather difficult to assess its condition without training and experience. In addition, dismantling and replacement, with such a device, is a long and laborious process, which means it is expensive.
6. Tensioners and dampers are involved in the timing chain - these are consumables that wear out quickly and need more frequent replacements than the timing chain itself.
TYPES OF FAILURES
1. At the timing chains, with full serviceability, a natural course is observed, which is compensated by the tensioners when the oil pressure is applied. A malfunction is considered to be a strong lateral beating of the timing chain, which appears when the links are stretched. It is possible to determine the real degree of chain stretching only with a qualified inspection of the gas distribution mechanism.
2. Backlash is a direct stretching of the chain, which is observed during long-term operation, can lead to jumping of the chain links and malfunction of the gas distribution mechanism, this leads to a decrease in the sensitivity of the engine when the accelerator pedal is pressed and an increase in fuel consumption.
3. Opening the timing chain of Nissan Qashqai - is the most dangerous damage to the engine, in the case of a chain drive of the motor it is not common, but it does take place. In the event of such a malfunction camshaft ceases to be associated with the crankshaft and can stop completely arbitrarily in such a position in which any of the valves of the gas distribution mechanism will be open. In this case, the piston, moving upwards, may collide with the valve, which will lead to its deformation and the car engine will face serious repairs. It should be noted that the timing chain breakage does not happen unexpectedly, almost always this is accompanied by changes in the operation of the vehicle, a decrease in its power, a change in gasoline consumption and the occurrence of extraneous noise.
To prevent and prevent the operation of the gas distribution mechanism, it is necessary to periodically troubleshoot the timing chain, this will save the car engine from damage, prevent premature engine wear and increase its service life.
CAUSES OF WEAR
1. Operation of the car Nissan Qashqai in extreme conditions. Frequent driving on unpaved roads, towing trailers, heavy loads, moving at high speeds leads to an increase in the load on crankshaft, untwisting it to maximum speed, which leads to stretching of the timing chain.
2. Since the timing chain is located inside the cylinder block, it is completely washed engine oil and as a result is very sensitive to its quality. In the case of using high-quality synthetic oil containing specialized detergents in its composition, the service life of the timing chain is significantly increased.
3. The timing chain involves parts that regulate the tension of the chain, they are consumable and need to be replaced periodically. During maintenance of the car, it is necessary to check the degree of wear of the tensioner and "damper", untimely replacement these parts can cause the chain to stretch and the links to skip.
SYMPTOMS OF MALFUNCTIONS
1. Increased consumption of gasoline by car;
2. Decrease in engine power; 3. The appearance of clanking and noise under the hood of the car when the engine is running;
4. Complete stop of the car on the move, when trying to start the engine does not start, and the starter rotates easier than usual;
5. Unstable operation of the Nissan Qashqai engine on Idling and in motion;
6. The appearance of shots in the receiver of the injector and the exhaust pipe.
All these malfunctions may indicate a shift in valve timing and a loosening of the chain tension. If on your car you notice one or more signs and this list - immediately contact the service station for an inspection.
HOW OFTEN DO YOU NEED TO REPLACE THE TIMING CHAIN
Frequency of replacement for any Supplies for Nissan cars Qashqai depends on the driving style and the mode of operation of the car. With extreme driving style and aggressive use of the vehicle, it is necessary to replace the timing chain as it looses and wears out.
Under normal operating conditions, it is necessary to replace the timing chain as planned, every 100 - 150,000 km. mileage. If your car has an analog belt, it must be replaced a little earlier than the time recommended by the vehicle manufacturer.
Trust your car only to professional specialists who are able to correctly troubleshoot the timing chain, assess lateral runout and backlash, replace and correct the operation of tensioners, chain drive “dampers” and replace the Nissan Qashqai timing chain.
