- If you use engine oil that does not ex-
pressly conform to Audi oil specification
VW 507 00, very serious and very expen-
sive damage to your vehicle 's engine will
occur . Engine damage caused by using
the wrong engine oil is not covered by
your New Vehicle limited Warranty .
- Not all commercially available oils con-
form to this very rigid Audi oil quality
standard even though they may be syn-
thetic-based and have the same viscosi-
ty.
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 water and the manufacturer's gly-
col-based coolant additive Gl2++ antifree ze
with anticorrosion additives (50% for USA
models; 60% for Canadian models). This mix-
ture both assures the necessary frost protec-
tion and protects metal components in the
engine 's cooling system from corrosion and
scaling.
It also raises the boiling point of the
coolant.
Do not reduce the concentration of the cool-
ant in the summer by adding plain water.
The
proportion of coolant additive must be at
least 50% but not more than 60% to main-
tain antifreeze protection and cooling efficien-
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi-
cle heating and engine cooling system.
Checking and filling 203
For year-round driving, antifreeze is added at
the factory for temperatures down to:
--31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
You can mix the Gl2 ++ coolan t additive with
other additives Gl2 + or Gl2. Always check
with your authorized Audi dealer .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS~
& in Working in the engine
comportment on page 194.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli-
mate conditions. This is especially impor-
tant if you live in a region where the
win-
ter is extremely cold. If necessary, in-
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad-
ditive G 12++ (check the label) for your
vehicle. This coolant additive is availa-
ble at authorized Audi dealers. Other
types of antifreeze can significantly re-
duce corrosion protection. The result-
ing corrosion can cause a loss of cool-
ant and serious engine damage.
- Do not add any type of radiator leak seal-
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse-
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
