General information
Depending on the vehicle's configuration, the auxiliary drive belt is used to drive devices such as the alternator, steering pump and air conditioning compressor from the crankshaft pulley.
On some models, the multi-ribbed auxiliary belt is equipped with an automatic tension adjustment device (depending on the route of installation and the number of components supplied). On other models, belt tension is adjusted by changing the position of the generator.
When installing the belt, care should be taken to adjust its tension.
Removal
1. Park the car on a level surface, set the parking brake and chock the rear wheels. Loosen the nuts securing the right front wheel.
2. Jack up the front of the car and place it on supports. Remove the right front wheel.
3. Remove the belt cover mounting screws.
4. Check the belt for factory indications of rotation direction. If necessary, apply the appropriate marking yourself.
Models with automatic auxiliary belt tensioner
Place an open-end wrench on the tensioner's central nut and turn the tensioner clockwise, overcoming the spring force.
Models without automatic auxiliary belt tensioner
1. Loosen the upper and lower generator mounting bolts one or two turns.
2. Move the generator down until it stops, rotating it around the upper support and overcoming the resistance of the spring.
All models
Remove the belt from the generator pulley, then from the other pulleys.
Installing the belt and adjusting its tension
Attention! When installing the belt, observe the direction of its rotation, using the corresponding marking as a guide.
Place the belt on the crankshaft pulley. Make sure that the belt ribs are correctly positioned in the corresponding grooves of the pulley.
Models with automatic tensioner
1. Using a spanner, turn the belt tensioner clockwise by the central nut.
2. Place the belt with the flat side under the tensioner roller, then throw it over the corresponding pulleys. Make sure that the belt ribs fit correctly into the pulley grooves.
3. The belt will be tensioned automatically when the tensioner is released.
Models without automatic tensioner
1. Overcoming the resistance of the spring, move the generator down several times until it stops, checking that it returns to its original position when released. If necessary, loosen the bolts another half turn.
2. Holding the generator in the depressed position, put the belt on its pulley. Release the generator - the belt should be tensioned under the action of the spring.
3. Without tightening the generator bolts, start the engine and let it idle for about 10 seconds.
4. Stop the engine and tighten the lower bolt first, then the upper bolt, to the required torque.
All models
1. Replace the belt cover. Tighten the bolts securely.
2. Install the right front wheel and lower the vehicle to the ground. Tighten the wheel nuts to the required torque.
