Coolant LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 196.
The cooling system is filled at the factory with a
permanent coolant.
It provides year-round protection from corrosion
and freezing down to –31 °F/–35 °C .
f Only use antifreeze authorized by Porsche. Checking coolant level The expansion tank with its filler orifice is located
in the rear luggage comp artment under the serv-
ice flap.
f Check the coolant level regularly.
When the engine is cold and the car is level the
fluid level must lie between the “MIN” and “MAX”
markings.
Topping off coolant
Warning!
Danger of serious personal injury or death
from scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
f Do not open the cap of the expansion tank
while the engine is hot.
f Allow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
f Keep coolant out of children’s reach.
f Also, keep coolant away from your pets.
They can be attracted to it should there be a
spill, or to used coolant left in an open contai-
ner. Coolant can be deadly to pets if consu-
med.
Risk of damage from overflowing coolant.
f Take care while topping off coolant not to soil the luggage compartment or items of luggage.
1. Switch engine off and let it cool. Please see the chapter “COOLING SYSTEM” on
Page 88. 2. Open the service flap by pulling the handhold.
3. Cover the expansion tank cap with a thick rag.
Open cap slowly and ca refully and allow over-
pressure to escape.
Then unscrew cap completely.
4. Only add a mixture of antifreeze and water in
equal parts, and do not exceed the ”Max.“
mark.
Antifreeze in coolant:
50% gives protection down to –31 °F/–35 °C
60% gives protection down to –58 °F/–50 °C
5. Screw cap firmly on.
6. Close service flap.

Maintenance, Car Care
If in an emergency pure water has been added, the
mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant in
dicates leakage in the
cooling system.
The cause should immediately be remedied at an
authorized Porsche dealer.

After the engine is switched off, the engine-
compartment temperature is monitored for
approx. 30 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
may continue to run or start to run.
f Carry out work in these areas only with the en-
gine off, the ignition off, and exercise extreme
caution.
Risk of injury. The radiator fans in the front
end of the car may be operating or
