EMS 5635 - radiator fan error
Fault

the speed of the radiator fan deviates from the speed set by the control unit.
Cause:
- Error in the fan clutch.
- Too little or no oil in the fan clutch.
- The oil viscosity in the fan clutch has changed.
Notes: The fan clutch is not working properly, reducing cooling capacity. Driving at high power for a long time is not possible.
Corrective Actions:
Check the fan clutch, you should feel a slight resistance when turning the fan by hand. If the fan can be turned freely, the clutch is damaged and also check that there is no oil leakage from the fan clutch. Oil leakage indicates clutch failure.
