the fan according to the temperature of the cool­
ant.
An auxiliary e lectr ic radiator fan * switches on and
off depending on coo lant temperature and other
veh icle operating conditions.
Afte r you switch the engine off, the a uxiliary fan
can cont inue running for up to 10 minutes -even
with the ignition off. It can even switch on again
l ater by itself
Q .&. , if
- the temperature of the engine coolant rises due
to the heat bui ld-up from the eng ine in the en­
