4.1.6. Radiator fan

Check

An electric food to the fan of cooling moves via the lock of ignition and the fuse. Management of the fan is made by a temperature-sensitive element established on the right side in a radiator.

The fan should turn on at excess of working temperature of the engine, that is some minutes prior to an entrance of an arrow of the index of temperature of the engine in red sector. If the fan does not turn on, remove wires from a temperature-sensitive element, connect them among themselves and include ignition. If the fan after that earns, possibly, the temperature-sensitive element which is subject to replacement failed. In case the fan still does not work, check, whether tension to a temperature-sensitive element moves. If tension on a temperature-sensitive element is absent, damage of wires is possible, or fused the fuse. If tension moves, check reliability of connection with mass of the second wire of the sensor. If the temperature-sensitive element and electroconducting in a good condition, means, possibly, the fan electric motor is damaged. The electric motor can be checked by tension giving on it additional wires from the accumulator.

Removal

MODELS WITH PETROL ENGINES WITHOUT AIR CONDITIONING

PERFORMANCE ORDER
1. Remove the electric socket from the engine of the fan of a radiator and release electric wires from support brackets.
2. Unscrew the top bolts of fastening of the fan of a radiator to a back part of a radiator.
3. Take the fan assembled from the bottom fastening and remove it from a motor compartment.
4. Unscrew nuts, remove a lock ring and remove the electric motor of the fan of a radiator from a casing.

MODELS WITH PETROL ENGINES WITH AIR CONDITIONING

PERFORMANCE ORDER
