Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with ant icorros ion addi­
tives (50% for USA models; 60% for Canadian models) . This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling.
It a lso raises the boil­
ing point of the coo lant.
D o not reduce the concentration o f the coo l­
ant in the summer by adding plain water .
The
proportion of coolant add it iv e mu st be at
lea st 50 % but not mo re than 60 %
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31° F(-35°C)USA
- - 40 ° F ( -40 °C) Canada.
I f you must add coo lant, use a m ixture of wa­
ter and coolant addit ive. Mixing the coolant
addit ive wi th dist illed wate r is recommended.
_& WARNING
Before yo u check any thing in the engine
compartment, always read and heed all
WARNINGS
¢ &. in Working in the engine
compartment on page 213.
(D Note
- Before winter se ts in, have the coolant
checked to see if the coolant additive in
-
your vehicle is sufficient to meet the cli­ mate conditions . This is especia lly impor ­
tant if you live in a reg ion where the win­
ter is extreme ly cold. If necessary, in­
crease the proportion of coolant add itive
to 60% .
- When adding coolant additive to your
cooling system , remember :
- We recommend us ing on ly coolant ad­
d it ive G12 ++ or G1 3 (check the labe l)
for your vehicle . This coolant additive is
avai lable at autho rized Audi dea lers .
Other types of antifreeze can signifi­
cantly reduce corrosion protection. The
resu lting corrosion can cause a loss of
coolant and serious engine damage .
- Do not add any type of rad iator leak seal­
ant to your vehicle's engine coolant.
Add ing radiator repa ir flu id may adverse ­
ly affect the function and performance of
your cooling system and could resu lt in
damage not covered by you r New Ve hicle

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

INGS
¢ &_ in Working in the engine compart­
ment on page 213.
.,. Park your vehicle on a level surface .
.,. Switch off the ignition .
.,. Read the engine coo lant level from the coo l­
a nt expansion tank¢
fig . 191, ¢ page 215, ..,.

fig. 188. With a cold engine, the coolant
lev el should be between the "min" and
"max" markings. When the engine is warm,
the level may be slightly above the "max"
marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus ­
t ration
<=> page 215.
To obtain an accurate reading , the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System<=>
page 15 will
illuminate until you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolant level
from time to time .
Coolant loss
Coolant loss may indicate a leak 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 .
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
&_ WARNING
-
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to 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 ap ­
plying light, downward pressure on the
top of the cap.
Checking and filling 221
-To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system
or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire .
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle 's engine coolant. Add-
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS <=>.&. in Working in the engine compart­
ment on page 213.
"'Turn off the engine.
"'Let the engine cool down .
"' Place a thick rag over the coolant expansion
tank
<=> page 220, fig. 191 and carefully
twist the cap counter-clockwise <=>_& .
"'Add coolant mixed in the correct ratio
<=> page 220, Coolant.
"'Twist the cap on again tightly.
Replacement engine coolant must conform to
exact specifications <=>
page 220, Coolant.
We recommend using only coolant addi-
tive G12++, G13 or in an emergency G12+. Do
not use a different additive. In an emergency
use plain water until you can get the correct
additive and can restore the correct ratio. This
should be done as soon as possible.
If you have lost a considerable amount of
coolant , then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex -
cess coolant will be forced out through the ..,.
