added, the correct ratio between water

itself
The radiator fan is driven by the engine via the
V-belt . The viscous clutch regulates the speed
of the fan accord ing to t he 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
c:;, &. , 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

er touch the radiator fan . -
The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
