Checking the drive belts of mounted units
1. Check the drive belt for damage and excessive wear and make sure it is properly seated in the pulley grooves. If the belt "squeals" or slips, check the condition of the contact surfaces of the pulley and the belt tension. If defects are found, replace the drive belt.
Attention: if the belt tension is loose, this will cause a slipping sound and rapid wear of the belt.
Note:
- It is not allowed to peel off the rubber from the cord on the inner (from the side of the ridges) and the outer surfaces of the belt, exposed or damaged cord, peeling of the ridges from the rubber base, the presence of cracks, peeling or wear on the sides of the belt and the ridges of the belt.
- After installing the V-ribbed belt, make sure that the treadmills of the belt fit correctly in the grooves of the pulleys.
Note:
- Term "used belt" refers to a belt that has been running for more than 5 minutes.
- Perform the belt deflection test when the engine is cold or at least 30 minutes after the engine has stopped.
- After installing the belt, start the engine and let it run for 5 minutes, and then check the belt tension again.
2. Check that the belt does not slip off the tensioner roller. Check the surface of the tensioner roller and its smoothness of rotation. If necessary, replace the tensioner.
3. (Engines 2.0 l / 2.4 l) Check the belt deflection at the points indicated by the arrows in the figure by pressing in the center of the belt span between the pulleys with a force of 98 N. Adjust the belt deflection if it does not correspond to the nominal value given in the table "Checking and adjusting the drive belts of mounted units".

Alternator Drive Belt Adjustment (engines 2.0 l / 2.4 l)
Attention:
- If the belt tension is loose, it will cause a slipping sound and the belt will wear quickly.
- Too much tension can damage the coolant pump or alternator bearings.
1. Loosen the nut "A" alternator pivot and locking bolt "IN" generator adjuster.
2. Turn the adjusting bolt to adjust the belt tension and deflection to nominal values.
3. Tighten the lock bolt "IN" generator adjuster.
4. Tighten the nut "A" articulated generator.
Tightening torques:
- screw "A": 35-55 Nm
- Bolt "IN": 20-25 Nm
- Adjusting bolt 8-12 Nm
5. Check belt tension or deflection and readjust if necessary.
Power steering pump and air conditioning compressor drive belt adjustment (engines 2.0 l / 2.4 l)
1. Loosen the lock bolt "A" on the tensioner pulley bracket.
2. Adjust the belt tension by turning the adjusting bolt "IN".
3. Tighten the lock bolt "A".
4. Turn the engine crankshaft one revolution, then check the belt tension. If necessary, repeat the adjustment.
Checking the tension of the accessory drive belt (engine 2.7 l)
Note: since an automatic tensioner is installed, it is not necessary to adjust the tension of the attachment drive belt.
Models with air conditioning.
1. Check that the adjusting mark of the tensioner is between the positions "MIN" And "MAX".
2. If the position of the mark does not match that shown in the figure, then replace the belt.
- A) Put a new belt on the tensioner roller and install the tensioner on the engine (if the tensioner is already installed, loosen its fastening bolts to install the belt.)
- Tightening torque: 20-27 Nm
- b) Install the belt on the pulleys in the following sequence:
- generator pulley;
- power steering pump pulley, control;
- crankshaft pulley;
- air conditioning compressor pulley.
- V) Using a 16mm wrench, turn the tensioner arm clockwise about 14 degrees and slide the belt onto the idler.
- G) Make sure the belt treads are properly seated in the pulley grooves.
- d) Check that the adjusting mark of the tensioner is between the positions "MIN" And "MAX".
