How to replace the timing chain of a Nissan X-Trail? When to replace the timing chain Nissan x trail: t31, t30 Timing chain replacement interval

On a Nissan X-Trail, timing chain replacement is required after a mileage of 180-200 thousand kilometers. It’s one thing when you have the X-trail in your own hands and the mileage doesn’t add up, but buying a car second-hand is another thing. It is highly advisable to have the timing chain on the X-Trail checked by diagnosticians, especially since replacing the chain is a common procedure. There are several algorithms for analyzing the remaining service life of the chain, as well as its stretching, for this they use the analysis of oscillograms of desynchronization of the crankshaft and camshaft sensors.

It is worth noting that the timing chain lasts much longer than the timing belt and is not afraid of a break; at the same time, the procedure for replacing a chain is significantly different from replacing a timing belt. As a rule, owners put off replacing it until the last minute, and someone tries to deceive the control unit and put out the eyesore of the X-Trail engine control lamp.

If there are strong doubts about whether the timing chain on the X-Trail has stretched or not, change it and only with a new one, do not skimp on matches. Someone manages to flip the teeth of the camshaft sprocket, but this does not solve the problem. When replacing the chain, the sprockets also need to be changed. By removing the side cover, you can see the output of the timing chain tensioner and if it is stretched, almost the entire tensioner comes out and the difference is 1-1.5 centimeters with a new chain installed.

To replace the chain with your own hands on the X-Trail, you need to remove the valve cover and remove the water pump, front end with oil filter. In general, the replacement process takes about 5 hours and is an expensive job, so the production of gears and guides should be taken into account in order to avoid unnecessary costs. If you decide to replace the timing chain with your own hands on the x-trail, then the chain itself, the tensioner and two long guides will be required for replacement. The performance of the machine can already be assessed during operation by engine noise, increased dynamics and fuel consumption.

The timing chain (gas distribution mechanism) is considered more popular among car manufacturers than the belt. It is equipped with many different engines. The Nissan X-Treal engine was no exception. Although the chain is considered more reliable, it, like any other unit, requires replacement sooner or later and it will be more profitable to do it yourself.

Most malfunctions in the gas distribution mechanism are related to the chain. Most often it simply stretches from wear and tear. But there are cases when the chain tensioner fails, which leads to excessive free movement of the chain and, as a result, its wear. One way or another, any timing fault makes itself felt almost instantly. A problem in the timing belt can be identified by several symptoms:

Excessive noise when the engine is running. At idle speed, the rumble of the chain is clearly audible.
Drop in power and throttle response. Unstable operation of the power unit at idle.
Increased fuel consumption

If one or a number of similar symptoms occur, the gas distribution system should be inspected. This is not difficult to do: you will need to remove the cover and inspect the tensioner. It should not be in the extreme position, and if so, then the chain should not have any play.

IMPORTANT. It is not always possible to judge the condition of the timing chain by inspection alone. Before replacing the chain, if you are not sure of its feasibility, have the car diagnosed at a service station.

Necessary spare parts for timing belt replacement

Since this process is very painstaking, it makes sense to replace all the gas distribution mechanism units at once. Required parts:

oil pump chain,
oil pump chain tensioner,
timing chain,
three chain dampers,
hydraulic timing chain tensioner,
crankshaft oil seal.

In some cases, replacement and acquisition also require: timing stars and a phase regulator. You will also need engine oil and antifreeze in the cooling system.

Which company to choose consumables is up to you to decide, but when it comes to choosing basic spare parts, there is no particular alternative. Only original spare parts from an official representative.

For several reasons at once: firstly, the quality of these parts is an order of magnitude higher than fakes, and secondly, more or less normal fakes still need to be looked for.

Carry out all work on a completely cooled engine.
Before starting the process, disconnect the battery terminals.
Carry out assembly carefully.
Any bolt must be tightened very carefully to avoid stripping the threads.
After assembly, wait several hours for the sealant to completely cure.

Safety regulations

To obtain the proper result and prevent possible injuries and accidents, you must adhere to the following safety rules:

Perform any manipulations only with a completely cooled engine.

Before working with the battery, disconnect its terminals.

Assemble engine components with extreme care and thoroughness.

Do not use excessive force to tighten the bolts to avoid stripping their threads.

Having completed the assembly, do not immediately turn on the mechanism, but wait until the sealant has completely hardened (this usually takes several hours).

Nissan X-Trail is a modern and improved car, as easy as possible to operate and maintain. But in case of breakdowns or the first signs of malfunction (including circuits), you cannot rely on your own strength, especially if you do not have all the necessary tools.

If you have the slightest doubt, it is better to seek help from specialists at a service station. At the same time, the Garage auto service guarantees the reliability and speed of the work performed. There is no need to skimp on the health of your car, because the lives of the driver and passengers often depend on it.

Video: Replacing the timing chain Nissan Xtrail (Nissan x trail)

Replacing the timing chain on a Nissan Xtrail is a rather labor-intensive process that requires some knowledge. If you are not confident in your abilities, or the necessary tool is missing, then it is better to contact a service station. In auto repair shops, such work is estimated at about 8 thousand rubles.

The main advantage of a timing chain drive compared to a belt drive is its much longer service life. On average, the need for a timing chain arises only after 200 thousand kilometers. Replacing a Nissan X Trail T30 timing chain is more complex than replacing a belt, but after checking out the material we offer, you will be able to handle it without any help.

When purchasing a car with significant mileage, be sure to pay attention to the degree of wear of this unit. Also, when replacing the chain (only replace it with a new one), be sure to also replace the sprockets.

How to install timing marks and timing chain on Nissan?

Excessive noise when the engine is running. At idle speed, the rumble of the chain is clearly audible.
Drop in power and throttle response. Unstable operation of the power unit at idle.
Increased fuel consumption

IMPORTANT. It is not always possible to judge the condition of the timing chain by inspection alone. Before replacing the chain, if you are not sure of its feasibility, have the car diagnosed at a service station.

When is it time to change?

It is not difficult to determine the degree of wear on the timing chain on a Nissan X Traill with a QR20DE engine; you just need to remove the cover and inspect the tensioner. The further it is extended, the more wear there is. If you find that the tensioner has pulled out almost completely, then this means only one thing - it’s time to replace it.

Required Tools

two sets of wrenches: spanners and open-end wrenches;
a set of spanners with curved ends;
set of heads;
gate;
pulley puller, you can borrow from someone for a while;
sealant 150 grams;
installation;
carburetor cleaner or similar fluid;
degreaser (alcohol and acetone will do);
new chain;
a pair of guides;
tensioner;
rags;
gloves.

Stages

At a service station, replacing the timing chain on a Nissan X Trail will cost you about 10 thousand, and in modern times even more. Therefore, you can try to cope with this work yourself.

Let us immediately warn you that replacing the timing chain on a Nissan X Trail is a rather troublesome process and it will not be possible to complete it in a day. When starting work, immediately think about the fact that you may have to leave the Trail overnight at the repair site.

To work better, placing the Nissan X Trail on an overpass is the best option. But you can also use a lift or build something else. Important! Make sure the vehicle is parked securely.

The first step is to remove the right wheel.
If protection is installed, dismantle it.
Use a wrench to pull back the tensioner and remove the belt.
We remove the pulley.
We do not remove the power steering pump. Simply unscrew the bolt from below and move it towards the interior.
Unscrew the two bolts and remove the tensioner.
The compressor can be left in place. But you need to unscrew a couple of bolts from the bottom and loosen the top ones. This must be done so that it does not press the pallet.
We support the motor from below.
We remove the right power unit cushion with fastenings. To do this, you need to unscrew four bolts from the motor and three from the spar. Using a screwdriver, unclip the wires that go to the generator.
Removing the power steering reservoir of the Nissan X Trail.
Remove the expansion tank.
Important! Leave the two unscrewed bolts remaining in their places in place. When assembling, place the pillow together with them, otherwise you won’t be able to fit them in!
Using the collar, unscrew the six bolts, disconnect the hose and remove the ski.
Unscrew the two exhaust pipe bolts.
The tray can be removed for convenience, but you can also leave it in place.
We unscrew the exhaust pipe fastening so that it can go as low as possible to make it easier to remove the pan.
We remove the dipstick. If the rubber band is damaged, this area can be filled with sealant during assembly.
Unscrew the pan bolts.
Using a pry bar or a screwdriver, tear off the sealant.
We remove the small hatch in the side cover.
Remove the side cover. Be careful with the bolts and the filter!
Now is a good time to check the guides.
Find and remove the tensioner. It is a small metal thing with a piston. It is located on the left and is held on by a pair of bolts.
Now you can remove the old timing chain.
We check the condition of all elements; perhaps some need to be replaced.
Proceed to assembly.
If replacement of sprockets is not required, then further work is performed in the following order.
The guide is placed on the right.
We install the tensioner.
When putting on the Nissan X Trail chain, pay attention to the following points.
On the chain itself there are 2 links painted one color and one link painted another. We combine a pair of links painted in the same color with the marks on the intake and exhaust camshafts, and a link painted in a different color with the mark on the crankshaft. Marks of different colors on the chain
We install the left guide.
Attention! When tightening the bolts, you must be careful, otherwise the thread of one of them may be stripped.
Install the side cover.
The edges must be degreased.
Apply the sealant carefully and evenly.
We install the pillow without screwing it to the spar. If you screw it on, you won't be able to fit the tray underneath.
We screw the pallet.
Further components and parts are installed in the reverse order.

Attention! When installing the hatch on the side cover, be sure to install the guide!
After completing the assembly work, wait a couple of hours to allow the sealant to dry.
Bolts must be lubricated with grease before screwing in!
The crankshaft on the Nissan X Trail cannot be rotated counterclockwise.

As you have seen, the chain process on the Nissan X Trail is not easy, but doable. But if you learn how to do it yourself, you will save a decent amount of cash, which can be spent on other purposes. If you have any questions, look at the photo report and video.

The company's engineers have ruled out the structural possibility of a break - the Nissan Xtrail timing chain is replaced if it is stretched or displaced. There is no need to worry that a break will occur and work related to engine restoration will be required.

The replacement procedure is not cheap and car owners, as a rule, react without enthusiasm to information that the chain is unsuitable for further use. Especially when they find out about the need to replace a certain number of related parts:

tensioner
guides
crankshaft and camshaft oil seal
valve cover gaskets
spark plug well gaskets
chain damper
stars

Oil and antifreeze are also changed completely.

With such an impressive amount of work, we need a 100% guarantee of correctly diagnosed faults. In those. Professional employees vouch for the accuracy of determining the cause of a breakdown, and if the chain has not exhausted its service life, the source of the problem will be found as quickly as possible.

If chain wear is confirmed, work on repairing the timing system is postponed, while the car continues to be used, all conditions are created for a major overhaul of the engine, which is not commensurate with the cost of replacing the chain.

Replacing the Chain on Nissan Xtrail QR20 part 2

- remove the oil receiver

— remove the dipstick (since it is removed with force, you may have to hit it from the bottom, the rubber will break, during assembly, fill it with sealant after cleaning it from dirt) do not forget to unscrew the bolt!

— unscrew the pan (there are a lot of bolts, be careful! 2 of them are hidden under a small cover through which the flywheel is visible, 4 are screwed into the box from the end) the numbers describe the order of loosening the bolts (assembly in reverse order) Attention! For some reason there are no 4 bolts screwed to the box in the picture.

when you unscrew it, you will need to tear off the sealant, you will need the help of an installation worker, you can pry it off in the area of 9 and 10 bolts, you can also carefully drive it in in places with a flat-head screwdriver. (I couldn’t remove it for a long time, I was afraid of breaking it, I loosened the fastenings of the box with the engine, a gap of 2 mm appeared, and then the current was given with force).

(don’t pay attention to the jack!) — remove the hatch in the side cover.

— now you can remove the side cover (be careful! There are a lot of bolts, if you miss even one, you risk breaking the cover when you peel it off the sealant) bolts numbered 1, 2, 3, 4. These are the bolts where the cushion was attached. You may ask: why did we remove the entire pallet? - because in the cover there is an oil pump from which one tube goes to the oil receiver and protrudes 2-3 centimeters to the bottom, and in the cover there are very tight guides, as well as a bushing on the shaft for rotating the pump, which will not allow you to tilt the cover to pull it out from the groove, plus sealant on all sides. (purely in theory, you can drill out the guides and somehow pull the sleeve off the shaft, it moves easily, tear off the sealant with force, but I didn’t do this)

When you remove the cover, do not lose the fine filter, it may fall out unnoticed! — there are guides on the left and right sides of the chain, remove them (to check for wear).

— on the left side behind the guide there is a tensioner (a small metal thing with a protruding piston) held on by two bolts, remove that too. - Next, remove the chain itself. (hang out the new and old chains and you will see how much the old chain stretches) in my case it is 2 mm. i.e. the chain does not need to be changed. The cause of my noises was the top guide. it fell apart into pieces, which I found in the oil receiver; the fastening of the right guide also broke, because of this the chain rubbed against the metal in places, and was all covered in small teeth.

the sprockets had a small wear (acceptable 0.15 mm) and I left them, I also left the old tensioner, since it had almost no wear (you can check this way: plug the oil hole in its body, clamp the piston inward and plug the hole in the piston with your finger, then Why, if the piston is released without opening the hole, the vacuum created inside should not allow the spring to eject the piston completely, at least immediately) this is a check for the tightness of its seal. besides, the old one looks much cooler than the new one, it even has its own filter. I also left the left guide, it is also much better than the new one, it has a good seat for the tensioner, I just had to sharpen it with sandpaper from the beatings. (old on top, new on bottom)

Assembly. If there is no need to change the stars, then we do everything in the following order: - install the right guide. - install the tensioner back (so that the piston does not jump out, insert the needle, since it is inserted into the new one. (for this there is a small hole on the body, and a groove on the piston)) - put on the chain. (on the chain there are two links of one color and one of another . two links must be aligned with the marks on the intake and exhaust camshafts, and a link of a different color with the mark on the crankshaft)

When to change

The maintenance schedule does not cover replacing the timing chain on this Nissan model. As a rule, with proper maintenance and subject to compliance with the manufacturer's recommendations, the drive produces up to 200 thousand km. Poor quality oil contributes to premature chain wear.

Replacement due to the degree of “fatigue” may be required after traveling approximately 120 thousand km.
If you purchase a used car and not directly from the owner.
With increased oil consumption in the internal combustion engine
If typical symptoms are detected indicating a malfunction of the timing belt.

Signs of trouble

Problems with the chain in gas distribution equipment are indicated by well-recognized manifestations of vehicle systems. If, upon visual inspection as much as possible, the extended tensioner does not convince of the need to install a new element, other arguments will soon be added to it.

Extraneous sounds. Clanking, metallic noise, knocking in the engine never bodes well for positive forecasts; if you notice them in the operation of the power unit, do not delay in contacting specialists.

Traction, revolutions. When these indicators are not stable, one of the reasons may be a stretched chain. Carrying out diagnostics at a car service is the only right decision.

Check. A light on the dashboard that comes on will leave no hope for the reliability of the timing drive. The signal will also indicate that the drive is stretched and the timing phases are shifted.

Additionally

The replacement procedure involves considerable expenses and a number of actions necessary for the full operation of the Nissan. The dismantling of a large number of vehicle mechanisms facilitates the implementation of complex, associated labor-intensive maintenance work, which makes it possible in the future to ensure efficient, normal operation of the engine, while spending a minimum of money and time. These include:

changing engine oil. Consult with Tech masters. about the quality of the composition used. If the lubricant does not meet the manufacturer’s recommendations, you should switch to a composition with more acceptable performance. This also applies to antifreeze.
flushing radiators: engine, air conditioner, variator, automatic transmission (if the transmission is automatic). This procedure should be carried out not only in the case of chain replacement work, but also during the operation of the car; usually, when using the car in off-road conditions, it is recommended to perform it every 10 thousand km, and for moderate driving it is enough to repeat the procedure every 30 thousand km.

Important!

The engine gas distribution system is one of the main ones, which allows for efficient and normal operation of the engine. It is not recommended to experiment or try to repair them yourself.

using a professional tool
thorough understanding of the operation and relationships between devices
the ability to quickly solve any problems that arise during the process

These are the main advantages of service at a car service center that specializes in providing Nissan repair services. Replacing the timing chain of a Nissan X-Trail outside a specialized service center is the responsibility of the car owner.

For Nissan X-Trail, replacing the timing chain is necessary as it wears out. The life of the chain is much higher than that of the belt, this is a serious plus. Replacement is required on average after 200,000 km. mileage

To determine the degree of wear, remove the cover and inspect the tensioner. The further it extends, pulling the chain, the higher the degree of wear.

Replacing a Nissan X-Trail timing chain requires the following equipment:

chain for oil pump;
oil pump chain tensioner;
crankshaft oil seal;
sealant;
seals;
timing chain;
hydraulic timing chain tensioner;
engine oil;
antifreeze;
because the oil filter will also have to be replaced during operation; a new filter will be required;
rags, work gloves, wrenches, screwdrivers;
It is more convenient to use pneumatic impact wrenches, which provide high-quality loosening and tightening of bolts and nuts. If you have the skill to work with this tool, the risk of stripping threads and tightening bolts crookedly is close to zero.

Many operations require significant physical force. If the repair is carried out by a woman, it will be impossible to do without pneumatic tools.

Timing chain

Replacing a Nissan X-Trail chain is not fun for half an hour or an hour. Almost half of the car will have to be disassembled. For untrained mechanics, assembly and disassembly alone takes several days. Correct assembly may take even longer, as it requires reading the manuals and reading the service instructions.

Replacing the Chain on Nissan Xtrail QR20 part 3

The lower chain is the balancer chain, we did not touch it. — after the marks are aligned, put on the left guide and remove the needle from the tensioner to remove it. the spring tensioned the chain.

Be careful when tightening the bolts, otherwise there may be trouble. I had the thread of the left guide fastening bolt torn off, to fix the problem you can use special bronze caps of larger diameter, which have threads inside, I didn’t have those, so I had to take a brass tube from the camera inside, a thread was cut into 6, from the top to 10, in The block has a hole drilled to size 9 and threaded. It turned out perfect.

this way you can solve most problems with rolled threads. — next we install the side cover (since the work of disassembling and assembling is very labor-intensive and time-consuming, be very careful when degreasing the edges and applying the sealant so that you don’t have to swear later! Apply the sealant in an even layer on the cover, and spread a thin film on the block itself with your finger made of sealant, for better adhesion) since the 4 bolts of the side cover are attracted by the cushion fastening, we install the cushion, but do not screw it to the spar! otherwise we won’t fit the pallet from the bottom. - screw the pallet. — we put everything in reverse order. — when you install the hatch on the side cover, don’t forget to put a guide!

It is advisable to let the sealant dry for at least 2-3 hours after assembly. It is not necessary to change the oil seal located under the pulley (but it is advisable), you can always reach it without problems (it leaked after assembly and had to be replaced). Along the way, while the belt has been removed, you can diagnose the tensioner and compressor bearings; there should be no noise or play during rotation (for reference, the tensioner contains bearing No. 203, costing 150 rubles, so it is not necessary to change the entire tensioner!) ALL BOLTS during assembly Lubricate with grease! NEVER ROLL THE CRANKSHAFT COUNTERCLOCKWISE, especially after assembly, since the tensioner is installed on the left side (if you look at the end of the engine) and when tensioning the chain in the other direction, it will be pushed through, the chain will gather at the crankshaft sprocket and there is an almost one hundred percent chance of slipping. This also applies to most “chain” motors! (I checked it myself with the cover removed!)

I also wanted to attach the factory instructions for repairing the engine, but the engine website does not support files larger than 600 kilobytes (the instructions are 25 megabytes) PS. During the repair, I used a cheap set of Chinese keys, broke the heads at 10, 12, 14, 17. - in general, complete G., although the keys and ratchets are good.

Preparatory stage

We turn off the power when the car is warm, and in the standard manner, carefully drain the engine oil and antifreeze into previously prepared containers. Be careful, the oil may be hot.

It is forbidden to drain used oil onto the ground, into reservoirs, or ditches. Taking this opportunity, it makes sense to remove the magnet trap for metal particles under the bottom of the car and thoroughly rinse and wipe with a rag.

Disassembly

The right front wheel will have to be removed. Protection, if installed, too. The lockers can be removed without any problems.

We remove the intake tract receiver and the upper engine mount along with the brackets.

Then the crankshaft pulley, accessory drive belt, tension rollers of attachments, power steering pump, generator, air conditioning compressor, power steering, exhaust pipe and everything that prevents access to the chain, bars and tensioner are removed.

Quite often along the way you will have to peel off the glued gaskets. Mark these places so that they can be coated with sealant during subsequent assembly.

Power steering reservoir

How to remove and replace a chain

When removing the chain, you first need to remove the tensioner located on the left. It is secured with bolts that need to be unscrewed.

After removing the chain, it is very advisable to inspect all components looking for damage, stuck metal fragments, debris, breaks, or cracks. Replace any damaged parts. It is advisable to replace the sprockets.

How to use tags on a chain? The chain itself has the following marks. 2 links have the same color markings and one link is painted a different color.

It is necessary to align the marks on the intake and exhaust camshafts; a mark of a different color must be aligned with the mark on the crankshaft.

Some carry out the procedure on jacks. This is inconvenient and not reliable. The vehicle must be securely secured. We recommend using a lift or, better yet, an overpass with special fastenings. This is safer and speeds up the process by an average of 3 times. A machine mounted on a lift can be inspected from all sides, with full access to the suspension, engine, and attachments.

When doing your own repairs, don’t be lazy to photograph each step in detail. This will be very useful for you during reassembly. Take photographs, even if it seems ridiculous and stupid to you, because everything seems to be completely obvious and understandable.

When replacing the chain, use Nissan X-Trail timing marks. How to set the marks can be found in the service instructions for the Nissan X-Trail engine. It is necessary to align the chain marks with the marks on the camshaft and crankshaft.

The use of a chain is more justified in terms of better controllability, reliability and strength of the Nissan X-Trail compared to a belt drive. However, replacing a chain on any Nissan X-Trail model is much more difficult than replacing a belt.

Drive belt replacement interval

The manufacturer recommends changing the drive belt on a Nissan X-Trail once every 50-60 thousand kilometers. The frequency of replacement may vary, as well as the need to change other consumables in the vehicle.

Factors affecting the frequency of drive belt replacement:

Weather;
Driving style;
Load on the power unit;
Load on auxiliary units.

About once every 15 thousand kilometers you need to monitor the tension of the drive belt. If necessary, it should be tightened.

Depending on the vehicle configuration, the length of the transmission element may vary. You can purchase original consumables or high-quality analogues from the following manufacturers:

The original belt has the Nissan name. An equally high-quality manufacturer is Gates.

Replacing the drive belt on a Nissan X-Trail T31 can be done directly after selecting the appropriate element. The vehicle can be taken to a garage or other warm, dry place.

What questions do car enthusiasts ask when it becomes necessary to replace a chain?

Question: What is a timing belt? Answer: This is a gas distribution mechanism.

Question: Is it possible to supply a used and reconditioned timing chain when replacing it? Answer: No, you can't. Only a new chain can be installed.

Question: What else will have to be changed when replacing the chain? Answer: Sprockets, oil filters, seals, gaskets, seals.

Question: How long will it take to replace a chain on a Nissan X-Trail? Answer: You will have to leave the car at the service station for several days. You may have to wait in line. In an emergency, you can replace the chain within a day. If you are traveling on your own, expect at least 2 days. For this reason, you should not start repairs on the cozy path under the windows. The car will be in a semi-disassembled state and it is better to carry out repairs in a workshop or in a spacious garage.

Question: Is special equipment required? Answer: Yes. You will need a good professional set of tools and special equipment for removing pulleys.

Question: What are the savings when repairing a car yourself? Answer: The workshop will charge you about 10 thousand rubles plus components for the operation of replacing the chain. If you already have the tools and don't make any mistakes, you may be able to save this amount, although it will cost you a lot of time. If there are no tools, purchasing them will cost more than the cost of repairs. In addition, tools take up a lot of space and need to be stored. Best of all, in special iron boxes.

Every time you try to repair the Nissan X-Trail yourself according to the instructions, you should remind yourself that stuntmen and circus performers are people too. They have exactly the same arms and legs as everyone else, which means that everything they can do is within the capabilities of any other person. Theoretically, this is true. In practice, anything goes.

Replacing a Nissan Xtrail timing chain is a technically complex process. More difficult than any trained person can do is backflip, for example, or play the violin. Everyone can. If he studies every day, with teachers, in a special educational institution. You will be surprised, but all installers, turners and mechanics at car service centers have a special education that allows them to perform high-quality car repair work.

If you don’t want to take risks, it’s better to leave the Nissan X-Trail in the hands of professionals. Eliminating unprofessional repair errors is usually more expensive than simply performing the necessary replacement of components. For this reason, auto repair shops strongly encourage videos and instructions for do-it-yourself repairs. Take instructional videos and car repair instructions with a grain of salt. They are no more effective than any other training videos, and you are risking your own rather expensive property completely independently and of your own free will. By the way, attempts to repair a car yourself are not insured events.

On the other hand, you can simply study the subject so that later, perhaps, you can perform some car maintenance work yourself.

Replacing the Chain on a Nissan Xtrail QR-20 (PHOTO REPORT)

Replacing the Chain on a Nissan Xtrail With a mileage of 220 thousand, I began to notice a gradually increasing sound similar to a grinding sound when starting the engine (until oil was pumped into the tensioner) and during sharp accelerations, at one hundred they said they urgently needed to change the chain, there was no money and no special desire, so While I was getting ready, I drove another 10 thousand, in the end the roar did not give any rest, it rattled like crazy at 2 thousand revolutions. Having looked through the Internet, I only found instructions for installing the chain itself. Purchased: chain - 3000 rubles. tensioner - 1200 rub. oil seal - 300 rub. and 3 guides - 1600 rub.
