a quick glance .

expansion tank
Before you check anything in the engine com­

INGS ¢ A in Working in the engine compart­
ment on page 165.
.,. Park your vehicle on a level surface.
.,. Switch the ignition
off .
.,. Read the coola nt level at the coolant expan­
s ion tank
¢ page 167, fig . 130. With a cold
engine, it must be above the "min" mark.
With a hot engine, it can be a l ittle above
the indica ted range.
The location of the coolant expans ion tank
can be seen in the engine compar tment illus­
tration
¢page 167.
To obtain an accurate read ing, the eng ine

The expans ion tank in your vehicle is equipped
with a n electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System¢
page 17 will
illum inate 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 leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool­
i ng system should be inspected immediately
Checkin g and fillin g 173
by your authorized Audi dea ler . It is not
enough merely to add coo lant .
In a
s ealed system, losses can o ccu r on ly if
the boiling point o f the coo lant is exceeded as
a res ult of overheating.
