Note:
The manufacturer recommends replacing the drive belt with a Nissan X-Trail once every 50-60 thousand km. run. The frequency of replacement can also vary, as can the need to change other consumables in the vehicle.
Signs that a Nissan X-Trail Drive Belt Needs to be Replaced:
- insufficient belt tension;
- overheating of the car engine;
- a strong squeal when the gas pedal is pressed sharply, powerful energy consumers and the air conditioner are turned on;
- smell of burnt rubber;
- detection of cracks on the belt;
- detection of belt abrasions up to the cord;
- detection of other mechanical damage;
- signals on sensors: notification of poor battery charge and poor performance of the generator.
Nissan X-Trail drive belt replacement (MR20DE engine)
1. Loosen the wheel nuts about 1/2 turn using a 21 mm socket or socket wrench.
2. Raise the front of the vehicle with a jack and place it on secure supports.
3. Finally turn away nuts of fastening, and remove the right wheel.
4. Pry with a flathead screwdriver, pull out the tabs and remove the 6 holders of the engine side mudguard.
5. Remove the side mudguard of the engine compartment and put it aside.
6. To loosen the Nissan X-Trail drive belt, put a 14mm ring wrench on the hex tab of the tensioner.
7. Turning the key clockwise, remove the tension roller from the belt.
8. Insert a metal rod into a special hole in the tensioner, thereby fixing the roller in this position.
9. Remove the Nissan X-Trail drive belt from the crankshaft pulley and pull it out of the engine compartment.
Note:
If the belt is in good condition and the work is not related to its replacement, first put a mark indicating the direction of rotation of the belt. When assembling, it will help to install it in the same position.
10. Examine a condition of the removed belt.
11. If there are signs of severe belt wear (disappearance of two or more adjacent ribs of streams in a section longer than 13 mm), longitudinal or transverse cracks, breaks, rubber peeling or oiling, replace the Nissan X-Trail drive belt with a new one.
12. Using the moment, check up a condition of the bearing of a tension roller. If during rotation of the roller the bearing has noticeable play, sticks or makes a lot of noise, the roller will need to be replaced with a new one.
13. Install the Nissan X-Trail drive belt in the reverse order of removal. Check that the belt lies correctly on all pulleys. Lastly, pull it over the pump pulley.
Note:
Observe the auxiliary drive diagram.
14. Check the mutual tension of the tensioner marks. With a new belt, the arrow will point to the top of the range. Over time, as the belt wears and stretches, mark 1 will gradually shift.
Note:
If the marks with the new belt do not match, the tensioner is most likely defective (the spring in its mechanism has broken or weakened). This tensioner will need to be replaced.
15. Install all removed parts in the reverse order of removal.
