Repair Volkswagen Passat B3-B4/Passat B3-B4>> Engines>> Diesel engines>> Belts of the drive of auxiliary units
Maple belt of the drive of the pump  of the hydraulic booster of steering
Removal of a maple belt is carried out in the following order:
– disconnect a wire from the negative plug of the rechargeable battery;
– slow down the car the parking brake;
– lift a forward part of the car and establish it on supports;
– remove the case of the air filter;
– remove the top casing of the engine (AFN engine);
– turn forward wheels against the stop to the right. For improvement of access to belts of the drive of auxiliary units remove a forward right wheel;
– weaken bolts of fastening of the pump of the hydraulic booster of steering and turn the pump around the top support to the engine;
– take off maple a belt from a pulley of the pump of the hydraulic booster of steering;
– examine maple a belt on existence of damages and if necessary replace it.
Installation of a maple belt is carried out in the sequence, the return to removal. The tension of a maple belt on early models is regulated by means of a tension bolt. For this purpose weaken nuts and bolts of fastening of the pump of the hydraulic booster of steering. Establish by rotation of a tension bolt the required tension of a belt and tighten a lock bolt. Tighten nuts and bolts of fastening of the pump.
On late models change of a tension of a belt is carried out by rotation of an adjusting bolt at which there is a turn of a pump housing. After adjustment tighten the fixing tension mechanism nut.
Repeatedly check a tension of a maple belt after a pro-collar of a bent shaft for two whole revolutions.
Flat belt of the drive of the generator
Carry out removal of a flat belt in the following order:
– disconnect a wire from the negative plug of the rechargeable battery;
– lift a forward part of the car and establish it on supports;
– turn forward wheels against the stop to the right and remove the right forward wheel;
– remove the plastic air ducts located in a zone of the right forward wheel;
– on the cars equipped with the hydraulic booster it is necessary to take off an auxiliary V-shaped belt of the drive of the pump of the amplifier of steering;
– note the direction of its movement on a flat belt.
For the cars equipped with the automatic mechanism of a tension
By means of an adjustable wrench turn the tension mechanism roller lever clockwise and take away a roller on the maximum distance from a driving belt.
For the cars which are not equipped with the automatic mechanism of a tension
Turn bolts of fastening of the generator on 1–2 turns;
overcoming spring resistance, turn the generator around the top support.
For all cars
Take off a flat belt from a pulley of the generator and then from other pulleys.
Installation and tension of a flat belt Is carried out in the following order:
according to a tag of the direction of the movement of a flat belt establish it on a pulley of a bent shaft so that edges of a belt got to the corresponding grooves of a pulley;
For the cars equipped with the automatic mechanism of a tension

Fig. 3.68. Head of the block of cylinders: 1 – a head of the block of cylinders, 2 – laying of a head of the block of cylinders, 3 – the directing valve plug, 4 – a forward cover of the bearing of the camshaft, 5 – a bolt of fastening of a head of the block of cylinders, 6 – a maslootrazhatelny plate, 7 – laying of a cover of a head of the block of cylinders, 8 – a cover of a head of the block of cylinders, 9 – a plate, 10 – a stopper of an oil-filling mouth, 11 – the union of the valve of the regulator of ventilation of a case


By means of an adjustable wrench turn the tension mechanism roller lever clockwise, overcoming resistance of a spring (fig. 3.68) ;
establish an auxiliary driving belt on pulleys in the following order: pump of cooling liquid, compressor of the conditioner and generator;
remove an adjustable spanner. The mechanism will make a tension of an auxiliary driving belt.
For the cars which are not equipped with the automatic mechanism of a tension
Turn the generator around the top support before full compression of a spring and track that it freely came back to a starting position. Otherwise turn off fastening bolts for a half-turn;
turn the generator around the top support before full compression of a spring and establish an auxiliary driving belt on a generator pulley then release the generator. At the same time there will be a tension of a driving belt;
connect the accumulator and start the engine on 10 with in the idling mode;
switch off the engine and tighten at first the lower then top bolts of fastening of the generator the required inhaling moment.
For all cars
There where is available, establish an auxiliary V-shaped driving belt of the drive of the pump of the hydraulic booster;
establish plastic air ducts on the places;
establish the right forward wheel and remove the car from supports.
