radiator AUDI A5 CABRIOLET 2014 User Guide

Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot .
_& WARNING
-The cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps .
- Turn
off the engine and allow itto cool
down.
- Protect your face, hands and arms from escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap .
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con ­
tainer clearly marked "poison".
(D Note
- Do not add coolant if the expansion tank
is empty. Air could enter the cooling sys­
tem and damage the engine. If this is
the case, do not continue driving . Seek
professional assistance.
- 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
¢ page 213 must be re­
stored as soon as possible.
Checking and filling 215
'
@) 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 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
du e to the h eat build-up from th e engin e 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 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. •
