Note!
Only a guideline, depends on vehicle
settings and equipment.
Viscous fan
The vehicle must be driven directly to a garage if the
coolant temperature or coolant level warning diode
comes on while driving and there is a fault with the fan
so that the fan can be checked.
Note!
Never cover the radiator. The
engine is fitted with a charge air
cooler and is therefore very sensitive
to air flow blockage (overheating
and reduced power). Do not
therefore cover the radiator (charge
air cooler) with boards, radiator
blinds etc.
Electrically controlled fan
On electrically controlled fans, it is not just the coolant
temperature that decides when the fan should start.
