coolant temperature AUDI Q7 2012 Owner´s Manual

268 Checking and filling
-If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the environment and
could cause an engine fire . Excess cool-
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze
c:::> page 265 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
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 accord ing 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 aux iliary
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
t he engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunligh t.
_&. WARNING
- To reduce the risk of personal injury nev­
er 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 au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

The fluid level may drop slightly after some
time due to the automatic adjustment of the
