Auxiliary drive belt tensioner (models with air conditioning)
1. Curved 7.0mm square rod
2. Square hole on the front side of the eccentric idler pulley
3. Bolt with an eccentric fastening of the idler pulley
4. 8.0mm hole for installing the automatic belt tensioner
Removing, installing and checking the tension of the drive belt is the same as for cars with gasoline engines, with the exception of cars with air conditioning.
Removing, installing and adjusting the tension of the auxiliary drive belt (models with air conditioning)
Removing
1. Disconnect the negative terminal from the battery.
2. Apply the handbrake and raise the front of the vehicle. Remove the right front wheel.
3. Unscrew the screws, disconnect the brackets and remove the protective arch from under the right front fender to gain access to the crankshaft pulley bolt. Remove the front mudguard if necessary.
4. Loosen the idler pulley eccentric bolt (see fig. Auxiliary drive belt tensioner (models with air conditioning)).
5. Insert a bent 7.0 mm square rod into the square hole of the tensioner eccentric.
6. Using a pin, turn the eccentric tensioner until the holes in the idler pulley bracket and in the hanger behind the bracket are aligned. After aligning the holes, install the appropriate rod in them (M8 bolt or rod with a diameter of 8 mm).
7. With the tensioner locked, turn the eccentric until the belt is completely loose. Remove the belt.
Installation and tension
8. Install the drive belt around the pulleys in the following order:
- air conditioning compressor;
- crankshaft;
- tension pulley;
- power steering pump;
- alternator;
- eccentric pulley of the tension mechanism.
9. Check the correct installation of the belt on the pulleys.
10. Rotate the tensioner eccentric pulley towards the drive belt until the lock is released. Without changing the position of the eccentric pulley of the mechanism, tighten the tension bolt.
11. Remove the bracket fixing bolt and turn the crankshaft four turns in the direction of its working rotation.
12. Check the alignment of the holes in the machine's tensioner and hanger bracket by reinserting the bolt.
13. Connect the negative cable to the battery, install the wheel arch and mudguard. Install the wheel and lower the car.
