To assure that the windshield washer and the
headlight washer systems also function at
freezing temperatures, anti-freeze/cleaning
solution must be added to the water be-
forehand. Follow the instructions on the can
for the right amount to be used.
Do not use engine coolant antifreeze or
any other solution that can damage the
car paint.
Cooling system (B)
For year round driving, anti-freeze is added
at the factory for temperatures down to:
-23° F/-30
0
C for U.S.
-40° F/-40
0
C for Canada
Because of its anti-corrosion properties, an-
tifreeze should also remain in the cooling
system for summer operation. Cooling sys-
tem capacity and specified anti-freeze and
water ratios are listed under "Filling
Capacities".
Use any quality phosphate-free anti-freeze
containing ethylene glycol, available at your
Porsche dealer. Anti-freeze other than
specified by Porsche for aluminium en-
gines and radiators may cause corrosion
of the cooling system, leading to engine
overheating and damage.
Only for topping up coolant, a small amount
of anti-freeze containing ethylene glycol and
phosphates may be used if recommended.
The anti-corrosion properties and the antif-
reeze consistency will diminish gradually. We
recommend renewing the coolant mixture at
least every 2 years.
WARNING
Even after the engine has stopped, the
radiator fan may continue running until
temperature of the coolant has dropped to
a certain level. Therefore, never touch the
fan blades as they will rotate spontane-
ously when the thermostat turns the fan on,
even with ignition off.
Checking coolant level in expansion tank
A correctly functioning cooling system re-
quires only minor care. The coolant level
should be checked from time to time, and
always before going on a longer trip.
The expansion tank with filler cap opening
is located in the right rear of the engine com-
partment (see illustration). Since the expan-
sion tank is transparent, it is not necessary
to unscrew the filler cap.
When the engine is cold, the coolant level
should reach the manufacturing seam on the
expansion tank. When the engine is warm,
the coolant level will be above the manufac-
turing seam.
Since the closed cooling system loses almost
no coolant, topping up is normally not re-
quired. An obvious loss of coolant indicates
leakage. The fault will be indicated by a fault
message in the information system display.
Top up the coolant and contact your dealer.
