Unscrewing of the central bolt of fastening of the fan of a radiator

Arrangement of bolts of fastening of a pulley of the water pump

Arrangement of the left bolts of fastening of the electromagnetic coupling on early models
1–case of the electromagnetic coupling;

2–electric sockets


Arrangement of a bolt of fastening of the electromagnetic coupling on early models

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator. On 4-cylinder petrol engines merge cooling liquid from cooling system, remove a radiator and the air filter.
2. Remove from a pulley of the water pump an auxiliary driving belt.
3. Unscrew the central bolt of fastening and remove the radiator fan from an axis of the water pump (see fig. Tightening of the central bolt of fastening of the coupling of the fan of a radiator, Unscrewing of the central bolt of fastening of the fan of a radiator).
4. Unscrew bolts and remove a pulley from the water pump (see fig. Arrangement of bolts of fastening of a pulley of the water pump).
5. On early models unscrew three bolts, fixing the coupling case to the water pump, remove the coupling, disconnect electric sockets and take the coupling from a motor compartment (see fig. An arrangement of the left bolts of fastening of the electromagnetic coupling on early models, the Arrangement of a bolt of fastening of the electromagnetic coupling on early models).
6. On later models unscrew fastening bolts on a back part of the case of the electromagnetic coupling, fixing the coupling to an arm. Remove an electromagnet the ny coupling, disconnect electric sockets and take the coupling from a motor compartment.

Installation

Arrangement of washers on a bolt of fastening of the fan of a radiator
1–bolt;

2–washer;

3–laying



PERFORMANCE ORDER
1. Installation is made in sequence, return to removal. Check that washers on a bolt of fastening of the fan of a radiator are correctly located (see fig. An arrangement of washers on a bolt of fastening of the fan of a radiator) also tighten all bolts of fastening the demanded moment.
