Audi Q5: Radiator fan

The radiator fan switches on automatically by itself.

The radiator fan is driven by the engine via the V-belt.

The viscous clutch regulates the speed of the fan according to the temperature of the coolant.

An auxiliary electric radiator fan switches on and off depending on coolant temperature and other vehicle operating conditions.

After you switch the engine off, the auxiliary fan can continue running for up to 10 minutes - even with the ignition off. It can even switch on again later by itself, if

  • the temperature of the engine coolant rises due to the heat build-up from the engine in the engine compartment, or
  • the engine compartment heats up because the vehicle is parked in intense sunlight.

WARNING

  • To reduce the risk of personal injury never touch the radiator fan.
  • The auxiliary electric fan is temperature controlled and can switch on suddenly even when the engine is not running.
  • The auxiliary radiator fan switches on automatically when the engine coolant reaches a certain temperature and will continue to run until the coolant temperature drops.
