A viscous fan drive clutch is installed on the car

The clutch reduces fuel consumption, reduces fan noise, and contributes to a better warm-up of a cold engine.

The viscous clutch is removed in case of malfunction, if the clutch does not turn on or does not turn on completely.

You will need the key "on 32".
