The electric motor of the fan of the cooling system GPB 0 130 303 204 (dv. ZMZ-4062) or 70.3730 (dv. 3M3-402) - collector, with excitation from permanent magnets

The electric motor is switched off via a relay by a TM108 temperature sensor installed in the radiator tank.

Design, check and replace the GAZ-3110 fan motor 3110

  • 1. Disconnect the wires from the electric fan switch switch
  • 2. Turn on the ignition and close the contacts

Replacing the radiator electric fan

3. If the fan starts working (and it didn’t turn on before when the engine overheated), then the sensor is faulty.

In this case, drain the coolant from the radiator and replace the sensor.

If the fan is not working, check that the 30 amp main fuse for the electric fan is good; check the fan motor.

The main fuse of the electric fan is installed in a common block with the main fuse of the on-board network.
