Serpentine belt: that it is necessary to know about drivebelts.
Drivebelts transmit twisting moment from a pulley of a cranked shaft to the generator, the liquid pump (viscous clutch the fan), the pump of the hydraulic booster of steering management and the compressor of a central air of air (depending on updating the car). Worn out or polluted drivebelts can cause bad cooling of the engine, insufficient force a charging current of the generator; unsatisfactory work of the hydraulic booster of steering management and a central air of air and consequently require in the constant control and duly adjustment or replacement.
For different devices of drives various methods of a tension of belts depending on the equipment and type of the engine are used. Pair drivebelts it is necessary to replace belts in pair even if one of them is worn slightly out.

The liquid pump - the generator. At replacement drivebelt it is necessary to weaken fastening of the generator and to move it in a direction to the engine for reduction of a tension of a belt that by pressing it in an average part between pulleys the deflection made 5-10 mm. Not weakening a tension of a belt, it is necessary to tighten a nut and a bolt of fastening of the generator.
On cars with the tension device it is necessary to watch not drawing a belt, and on the models which have been not equipped by the tension device, it is possible to use the lever for a tension of a belt at moving the generator from the engine. To put on or remove a belt from pulleys it is necessary with use only wooden or plastic levers.

The pump of the steering hydraulic booster. Replacement drivebelt of the pump of the steering hydraulic booster is similarly carried out. Difference consists in a different arrangement buckles and adjusting bolts and nuts. At V-shaped engines access to the pump of the steering hydraulic booster is better, than at straight the engine.

The compressor of a central air. At cars on which the compressor fastens on buckle for possible regulation, replacement drivebelts is similar to their replacement by the liquid pump (generator). However the deflection of a belt should be only 1-2 mm.
At models of cars on which the compressor is installed motionlessly, the tension of a belt is carried out by a choice of number of adjusting washers which are installed between components of a pulley for change of a stream of a pulley of a cranked shaft.
For removal drivebelt it is necessary to turn away a pulley from a nave, to remove components of a pulley and a washer then the belt can be removed. At installation of a belt it is necessary to pick up washers of corresponding thickness. Thus it is necessary to consider, that at installation of washers between components of a pulley the tension of a belt decreases, and in front increases. After selection of internal washers the remained washers can be installed in a forward part of a pulley for their further use.
