Coolant
level
Follow the instructions in the "Cautions" chapter.
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 j- 35°C (Nordic
countries - 40°F j- 40°C).
Only use antifreeze authorized by Porsche.
Checking coolant level
The expansion tank with its filler orifice is in the
engine compartment.
~
Check the coolant level regularly through the
transparent expansion tank.
When the engine is cold and the car is level the
fluid level must lie between the "Min." and "Max."

Warning!
Danger of serious personal injury from
scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
~
Do not open the cap of the expansion tank
while the engine is hot.
~
Allow the engine to cool down before opening
the cap and protect your hands, arms and
face from any possible escape of hot coolant.
~
Keep coolant out of children's reach.
~
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 con-
tainer. Coolant can be deadly to pets if con-
sumed.
1. Switch engine off and let it cool.
See the chapter on the "Cooling system".
2. Cover the expansion tank cap with a thick
rag.
Open cap slowly and carefully and allow over-
pressure to escape.
Then unscrew cap completely.
3. 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 j- 35°C
60% gives protection down to - 58°F j- 50°C
4. Screw cap firmly on.
If in an emergency pure water has been added,
the mix ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant indicates leakage in the
cooling system.
The cause should immediately be remedied at
an authorized Porsche dealer.
