2015 AUDI RS7 SPORTBACK engine coolant

218 Check ing and filling
fig . 188. With a cold engine, the coo lant
l evel should be between the "min" and
"max" markings . When the engine is warm ,
the leve l may be slightly above the "max"
mark ing .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
9 page 213.
To obtain an accurate reading, the engine
must be switched off .
The expans ion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning l ight in the Auto-Check System
9 page 15 w ill
illum inate unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time .
Coolant loss
Coolant loss may indicate a le ak in the cooling
system . In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
s ealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scald­
ing from hot coolant by followi ng these
steps .
- Turn off the engine and allow it to coo l
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 carefu lly in
a counter-clockwise direction w hile ap­
plying light, downward pressure on the
top of the cap . -
To avoid being burned, do not spi ll anti­
freeze or coolant on the exha ust system
or hot engine parts. Under certain cond i­
tions, the ethylene glycol in engine coo l­
a nt can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your veh icle's engine coolant. Add­
i ng radiator repair fluid may adverse ly af­
fect the funct ion and pe rformance of you r
cooling system and could result in damage
not cove red by your New Veh icle Limited
War ran ty.

Be very careful when adding engine coolant.
Befo re you check anyth ing in the eng ine com­
partment,

If you have lost a consi derable amount of
coolant, then you should add co ld antifreeze
and cold water only when the engine is co ld .
Always use
new engine coolant when refi lling.
D o not fi ll coolant above the "MAX " mark . Ex­
cess coolant will be forced out th rough the
p ress ure rel ief valve in the cap when the en­
g ine becomes hot .
A WARNING ,_________
-The cooling system is under press ure and
can get very hot . Reduce the risk of
sca ld ing from hot coo lant by following
these steps.
- Tur n
off the eng ine and a llow itto cool
down.
- Protect your face, hands and arms from
escap ing f lu id a nd steam by cover ing
the cap wi th a la rge, thick rag.
- Turn the cap slow ly and very ca refully
in a cou nte r-clockw ise d irect ion while
a pply ing ligh t, downw ard p ress ure on
the to p of the cap.
- To avo id being burned, do no t sp ill an­
tifreeze or coolan t on t he exhaust sys­
tem or ho t engine parts . U nder certa in
conditions, the ethylene glyco l in en­
gine coolant can catc h fire .
- Antifreeze is poisonous . Always store an ­
tifreeze in its original container and we ll
o ut o f the reach of children.
- If you drain the coolant , it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
@ Note
- Do not add coolant if the expansion tank
i s empty . Ai r could enter the cooling sys­
tem and damage the engine. If this is
the case, do not continue driving. Seek professional assistance.
- Coolant po llutes the env ironment and
could cause a n engine fire. Excess coo l­
ant wi ll be forced out through the pres­
sure re lief valve in the cap when the en ­
gine becomes hot.
Checkin g and fillin g 219
-If, in an emergency, on ly wate r can be
added, the correct ratio between water
and antifreeze ¢
page 217 must be re­
stored as soon as possible.
@) For the sake of the environment
Drained coolant sho uld not be reused. A l­
ways d ispose of used coolant while observ­
i ng a ll environmental regulations.
, Radiator fan
The radiator fan switches on automatically by
itself .
An auxiliary electric radiato r fan switches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing cond it ions.
After yo u switch the eng ine o ff, the aux iliary
f an can continue running for up to 10 m inutes
- even with the ignition off. It can even switch
on aga in later by itself¢ .&. , if
- the temperatu re of the engine coo lant rises
du e to the h eat build -up from th e engin e in
the engine compa rtment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlig ht.
A WARNING ~
- To reduce the risk of persona l inju ry nev-
er touch the radiator fan .
- The a uxiliary electric fan is tempe rat ure
contro lled and can switch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan sw itches on a u­
tomatically when the engine coo lant
reaches a certai n temperature and will
continue to ru n until the coo lant temper­
ature drops. •
