Only the simplest verification is allowed on your own.
Examination
1. Warm up the engine and move to idle.
2. The fan should turn on after no more than 2 minutes (the arrow of the temperature gauge should be on the edge of the red sector).
3. Otherwise, stop the engine and disconnect the connector from the fan.
4. If the fan does not turn on when 12V is connected directly to the connector output, then the electric motor is faulty.
5. If the fan turns on with direct voltage, then the wiring, control unit or thermal switch is faulty (check procedure see subsection 4.6.1).
6. The rest of the checks are performed in the car service.
Removing
1. Disconnect the battery from the ground.
2. Disconnect the connector from the motor.
3. Loosen the screws, lift and remove the fan assembly with the shroud.
Installation
Installation is carried out in the reverse order.
