Ribbed belts
Ribbed belts drives the generator, water pump, air conditioning compressor, power steering pump and engine cooling fan. On some models, the drive water pump is a separate V-belt.
Withdrawal Disconnect "weight" from the storage battery. When removing the V-ribbed belt is necessary to consider the following:
A WARNING Chalk, markers or paint mark the direction of rotation of poly V-belt. After setting the belt rotates in the opposite direction, which may result in its destruction. |

1. Install the pulley-damper V-ribbed belt 7 (Fig. 3.1.28) on the crankshaft is only possible in one position. 2. A bolt with a special head 14 is installed before installing the generator bracket. 3. The bolts 25 fastening the generator bracket are of different lengths and are fastened in a specific sequence. 4. When installing a pulley power steering pump 31 protruding end surface of the pulley should be directed to the front of the car. Cars with air conditioning Drive by a separate air conditioner compressor Poly-V belt.

Wrench, turn clockwise to the V-ribbed belt tensioner alternator, fan and water pump. As a result, the tension will ease (Fig. 3.1.30). Remove ribbed belt from pulleys and V-ribbed belt tensioner release.
Setting Put on a belt at first on the crankshaft pulley and then on a pulley power steering pump. Wrench, turn clockwise tensioner V-ribbed belt, put the belt on the alternator pulley. Slowly release the tensioner to tighten the belt.

When installing the V-ribbed belt, pay attention to its location right on the pulleys (Fig. 3.1.31). Install the air conditioning compressor belt and adjust its tension. To do this, a torque wrench to the hex head belt tensioner air conditioning compressor in the "7 hours", create a pre-tension 25 N ?� m (see. Fig. 3.1.29) and in this position, tighten the tensioner bolts to 20 N ?� m . Start the engine, check the location and fluidity belts.
