Radiator fan and thermal switch

To check the operation of the radiator fan, disconnect the wire connector from the thermal switch, install a short jumper between the wires and turn on the ignition - the fan should start working

The fan together with the shroud can be removed without removing the radiator from the vehicle. Disconnect the wire before removing the fan "masses" from the battery.

The fan motor is attached to the casing with three nuts and can be removed quite easily.

The fan motor cannot be disassembled, but the fan impeller can be removed by unscrewing the bolt on the impeller hub and carefully pressing the impeller off the motor shaft.

Installing the fan is carried out in the reverse order.

To replace the thermal switch that controls the operation of the fan, you need to drain the liquid from the cooling system, disconnect the wire connector and carefully unscrew the thermal switch from the radiator tank. On engines of 1.1 and 1.3 liters, the thermal switch is located in the right tank of the radiator, and on larger engines - in the left tank.

When unscrewing the thermal switch, be careful not to damage the radiator. Always use a new gasket when installing.

Remember that since August 1978, thermal switches have been installed with a higher response temperature than on engines of previous releases.
