Cars manufactured by Nissan are distinguished not only by comfort, ease of use, but also by the highest reliability. But for a number of reasons, some components sometimes fail, for example, the clutch on the Nissan X Trail, if used incorrectly or after its resource has been exhausted, may fail, and then it may need to be replaced.
Replacing the clutch on a Nissan X Trail is no more difficult than replacing this assembly on any other car, and after studying our instructions, you can handle it yourself. It is better to do the work with an experienced partner - it will be difficult to cope with some operations alone, and the procedure itself requires the dismantling of many nodes.

Causes of pedal failure
The clutch on the Nissan X Trail can fail for various reasons, but, like on other cars, they are all standard. This is, first of all, overexposure of the pedal, frequent slippage, work at increased loads.
DIY replacement instructions
By itself, the process of replacing the clutch on the Nissan X Trail is not difficult, and by carefully studying the instructions, you can handle it - there is no need to be an auto mechanic for this.
What will be needed?
Steps
Everything on the Nissan X Trail, of course, is best done on a special car lift, but a pit or overpass would be a good option. If this is not possible, then, taking precautions, you will have to jack up the car and resort to installing various supports. Be sure to block the rear wheels so that the car does not roll.

Overheating does not depend on the time of year. It is clear that in the summer the likelihood of such a nuisance is greater. But even in winter you should not relax.
First of all, malfunctions lead to an increase in temperature, as well as a violation in the operation of the unit itself. The amount and condition of the coolant must be constantly monitored. Its deficiency raises the temperature above the norm, and its absence leads to overheating.
It is better to use a liquid with a high boiling point and a low freezing point. It is necessary to change it within the time limits set by the manufacturer or in case of loss of antifreeze properties, such as density and color.
Sometimes an air lock does not allow the coolant to circulate throughout the system, thereby raising the temperature. Some vehicles have air bleed plugs. In their absence, a thin hose is usually removed in the area of \u200b\u200bthe intake manifold.
A valve is installed in the radiator cap, which is designed to relieve excess pressure. When it breaks, the system boils up to the rupture of hoses or weak points of the radiator. This can also be caused by using a plug with an inappropriate pressure parameter. If antifreeze is poured into the system only through an expansion barrel, then the valve is located in the lid of this barrel.
The thermostat can become a cause not only because of its breakdown, but also because of the opening temperature. In hot weather or in traffic jams, early opening of the thermostat leads to overheating of the motor, and its failure in any weather.
A good radiator cooling fan with a sufficient number of blades is required to keep the temperature down. With a mechanical rotation drive, the fan may stop due to a broken belt or a broken impeller.
With electric control, the fan activation temperature sensor and the electric motor are responsible for switching on. In a hydraulic or hydromechanical system, the viscous coupling most often fails.
The coolant pump ensures constant circulation of fluid through the system. Its stop may be caused by a broken belt or broken internal parts.
Improper operation of the engine increases the stress on its parts and causes an initially elevated temperature, which a healthy cooling system cannot cope with. These include:
breakdown of the cylinder head gasket;
- incorrectly set and adjusted ignition or fuel injection system;
- intake valve burnout;
- detonation;
- high engine speeds;
- lack of lubrication of motor parts.
But sometimes, indirect reasons can become the basis for overheating of the motor. The lack of a counter flow of cold air may occur due to the insulating cape not removed from the radiator grille.
External contamination of the radiator increases the temperature of the liquid in it. This is due to the fact that flying insects and dirt during operation close up the air cells in the radiator. The stove radiator also requires periodic external cleaning.
Dirt and deposits inside the cooling system also provoke overheating.
To prevent overheating, it is necessary to regularly monitor the health of the cooling system. Since the overheating and temperature indicator on the instrument panel gives a signal when the engine temperature has already warmed up to a critical point.
Overheating due to windscreen in winter
It is advisable to insulate the engine compartment in winter, and it would be nice to protect the radiator from the wind. The barrier on the way of drafts helps to warm up the engine faster. Also, one of the main things is that the wind protection prevents the formation of condensate at the points of contact of hot vapors with supercooled parts.
Most often, cardboard is placed in front of the radiator to protect against cold air. If there are no gaps between the surface of the cardboard and the surface of the radiator, in other words, the cardboard is close to the radiator, then there will be no room for air circulation. This is exactly the case when the road to hell is paved with good intentions.
Overheating an engine with a tightly packed radiator is easy. Even more than that, overheating the motor can lead to cracks in the metal. After that, it will be necessary to change the damaged part, in fact, this is almost an overhaul of the engine. And if the owner leaves at least a centimeter of space between the radiator and the cardboard, then the car will drive and drive.
Is the coolant not freezing?
It is also worth remembering such a moment: did you add water to the expansion tank in the summer or maybe even went on water. If enough water is left in your cooling system during the winter, that water can freeze.
Let's see what happens in this case: when the engine is started and warmed up, the temperature will begin to rise rapidly. There will be no circulation of the coolant in the system, since instead of the liquid in the pipes there will be frozen or viscous slurry. In such a situation, instantaneous overheating of the engine is precisely ensured, so if in doubt, measure the density of the coolant, and it is best to flush the system in advance and replace the coolant at the end of summer.
On Nissan X-Trail vehicles with a manual manual transmission, a hydraulically actuated friction-type disc clutch is installed. The driver of the car, pressing the clutch pedal, actuates the clutch master cylinder, which in turn pressurizes the clutch fluid.
The working fluid of the clutch drive mechanism enters the clutch master cylinder. The rod of the working cylinder acts on the clutch fork, which in turn presses on the release bearing. The bearing, mating with the petals of the basket, releases the clutch disc, interrupting the transmission of torque from the engine to the gearbox. In contact with each other, under the action of the clutch basket, the clutch disc and flywheel form a frictional transmission of torque from the engine to the gearbox.
On later models (31 bodies), a clutch with a release mechanism can be installed, which is a hydraulic release bearing that combines the clutch slave cylinder. In this case, the clutch fork and the outer working cylinder are missing.
The main malfunctions of the Nissan X-Trail clutch
According to statistics, car owners most often turn to repair and replacement of the clutch at service stations Nissan X-Trail with 2 liter engine. On this model of car, a clutch mechanism with a driven disc measuring 225 mm is installed.
More powerful Nissan X-Trail with 2.5 liter engine equipped with a clutch mechanism with a driven disc with a diameter of 240 mm.
Signs of a Nissan X-Trail clutch failure are:
- the appearance of incomplete engagement of the clutch, while slipping of the clutch disc occurs, which is expressed, in the engaged gear, in a sharp increase in engine speed when trying to accelerate and there is no acceleration of the car;
- the appearance of an incomplete disengagement of the clutch mechanism, which is expressed in difficult gear shifting;
- the appearance of vibration when turning on and off the clutch mechanism;
- the appearance of a persistent burnt smell during clutch operation;
- the appearance of noise when the clutch mechanism is turned on and off;
- the occurrence of jerks during clutch operation.
Car clutch problems can be divided into two groups:
- malfunctions of the hydraulic drive of the clutch mechanism
Malfunctions of the clutch itself
The main malfunctions of the hydraulic clutch of a car:
1. Leakage of the hydraulic drive line, which leads to air locks in the line;
2. Insufficiency of the stroke of the piston of the working cylinder, due to the low pressure of the working fluid in the hydraulic system;
3. Malfunction of the master or slave cylinders of the clutch.
The main malfunctions of the mechanical part of the clutch:
1. mechanical wear of the friction linings of the clutch disc;
2. disc wear and, as a result, uneven adjoining of the disc to the flywheel;
3. oil getting on the disc friction linings;
4. wear of clutch basket petals;
5. Damage to the damper springs of the clutch disc;
6. wear of the release bearing;
7. mechanical wear of the clutch fork;
8. mechanical wear of the flywheel surface.
Main Causes of Nissan X-Trail Clutch Failure
There are several points that can be distinguished as the main reasons for the breakdown of components and clutch mechanisms of a Nissan X-Trail car:
1. Driving style
Proper operation of the clutch mechanism involves smooth starting without an unreasonable increase in engine speed. Increased wear and tear occurs when these basic operating rules are violated. So, for example, the resource of the clutch mechanism is significantly reduced with a sharp start.
2. Poor quality parts and components of the clutch mechanism
When repairing the clutch mechanism, it is necessary to use high-quality parts. Only the use of original spare parts can guarantee stable operation throughout the entire service life.
Nissan X-Trail clutch - original or good analogue?
Some time ago, car owners preferred to buy cheap analogues that are not inferior in quality to the original Nissan X-Trail clutch. Now the situation on the spare parts market has changed somewhat, and we can say that the dumping prices of official spare parts manufacturers are often comparable to the prices of high-quality analogues. There are not many companies on the market that offer a non-genuine clutch on the Nissan X-Trail.
The clutch is a part of the vehicle mechanism, which is very dependent on the operating conditions of the vehicle. It cannot be unequivocally said that a non-original clutch is worse than the original. The AutoPride service network recommends purchasing an original Nissan X-Trail clutch or a high-quality Japanese equivalent from Exedy.
The compact crossover Nissan Xtrail has earned the respect of motorists due to the endurance of its transmission and excellent technical reliability in general. But even such a reliable car from the Japanese automaker has its weaknesses, one of which is the clutch. Repairing this part of a Nissan car is not an easy task, so it’s worth understanding in more detail how this is done.
In fact, clutch replacement is a standard procedure associated with restoring the performance of this assembly. In addition to repairing this mechanism, other technical problems may arise that require the intervention of a master. Malfunctions in the clutch of a car can significantly complicate the control of the vehicle, becoming the culprit of significant problems.
Often the cause of clutch failure is failure to follow the basic rules for operating a car and ignoring regular maintenance. Due to ignoring problems at the first stage, when the motorist waits until the last moment for a serious breakdown to occur, the mechanism can wear out so badly that a complete replacement is indispensable.
Another important factor affecting the durability of this unit is the driving style of the motorist.Aggressive driving with unreasonable gas shifts, abrupt starts and stops have a very negative effect on the operation of this mechanism. Here, the car owner himself becomes the culprit that a Nissan Xtrail clutch replacement may be necessary.
Do-it-yourself clutch repair or restoration in an unreliable auto repair shop also does not lead to anything good.
With such low-quality repairs, in an attempt to save money, spare parts are often installed that are not of the best quality, which have a short service life. For this reason, if you have problems with the clutch, it is more correct to visit an auto repair shop for diagnostics and repairs.
Clutch replacement symptoms:
- Insufficient free travel of the clutch pedal;
- Slipping and freezing when shifting gears;
- Difficulty shifting or skipping gears;
- Spontaneous transition to neutral gear;
- Malfunction notice on the instrument panel.
If you have problems with the free play of the clutch pedal, then you need to check it and make adjustments. If slipping or freezing when shifting gears, it is more likely that it will have to be completely replaced. Most often, the first sign of slipping is a clear and unreasonable increase in engine speed at the time of climbing a steep hill.
It is important to be able to independently determine the first symptoms of the need for clutch repair and to know the approximate frequency of service and repair.
Clutch replacement interval
The automaker sets the approximate timing for checking the clutch mechanism of a Nissan Xtrail car, and the frequency of its replacement depends entirely on the operating conditions of this unit. This applies, first of all, to specific road conditions and driving accuracy, which depends on the driver personally. Therefore, it is not always possible to determine for certain when a replacement may be needed.
Undoubtedly, maintenance is carried out more often than replacement. The engine hours that the motorist spends in traffic jams and warming up the engine during the cold season are necessarily taken into account. Most often, the replacement of this element of the car's transmission needs to be replaced after about 40-50 thousand kilometers or if you notice obvious signs of a malfunctioning mechanism.
It is important not to wait for your car's clutch to completely fail, but to maintain it regularly and replace it at the first sign of such a need.
Necessary spare parts for clutch replacement
Replacement means the installation of a number of new parts and mechanisms that are an integral part of this vehicle assembly. Some of them may fail more often, while others practically do not make themselves felt throughout the entire period of operation of the vehicle. To determine exactly what needs to be replaced for you, they will be able to help in a car repair shop.
List of replacement parts:
- Clutch disc;
- clutch basket;
- Release bearing;
- Crankshaft oil seal.
The clutch disc must be changed after about 150 thousand kilometers, subject to careful operation. If the car was driven by an inexperienced driver or a fan of extreme driving, then such a replacement may be required much earlier. It is imperative to change it in time so that the flywheel or basket is not damaged.
The clutch basket changes much less frequently than the disc, subject to careful operation and timely replacement of adjacent parts and mechanisms that fail. You should especially carefully monitor it if the car is not new and has been operated before you do not know how long.
A failure of the release bearing can be identified by the characteristic signs that manifest themselves in increased noise when the clutch is released. It must be changed in a timely manner, because if this is not done, then other components of this assembly may be significantly affected.
Replacing the crankshaft oil seal is not necessary, but it will not be superfluous, since during the replacement of the clutch, repair work is still carried out next to it. In order not to subsequently deal with such a replacement separately, it is better to perform it immediately. The crankshaft oil seal serves for a long time, but it is still better to combine such work.
It is important to install spare parts of original quality or high-quality analogues that are not inferior in their characteristics, so that repairs do not have to be carried out again after a short period of time.
The procedure for replacing the clutch
All Nissan Xtrail modifications, regardless of engine and gearbox type, have the same replacement procedure. The cost of such work is also approximately the same for all Nissan models. Careful observance of the order of work will help to avoid mistakes during repairs.
Work order:
- Raising the car on a lift or installing it on a viewing hole.
- Removing the front wheels.
- Carrying out complex work on the dismantling of the checkpoint.
- Unscrewing the pressure plate casing bolts and removing it together with the disc.
- Removing the driven disk.
- Installation of a new disk and its centering.
The assembly of the already repaired mechanism with the replacement of all worn parts is carried out in the reverse order. It is necessary to pay attention to this stage of work so that you do not have to return to the repair again. Be sure to check the result of the work performed.

When repairing a Nissan Xtrail clutch, it is desirable to use original spare parts, but not mandatory. The main thing is to know which of the analogues have the appropriate quality and they should be selected according to the VIN code. If you have little experience in this, then it is better to seek the advice of specialists.
During the replacement of the Nissan Xtrail clutch, it is also recommended to carry out related repair work. Most often, a new oil seal is required on the crankshaft and gearbox input shaft. The cost of repair and maintenance can be determined only after the diagnosis.
