Porsche 911 Carrera - Manual (Page 235)

Coolant Level
General information
Please observe the chapter ”EXERCISE
EXTREME CAUTION WHEN WORKING ON
YOUR VEHICLE” on page 232.
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 .
Only use antifreeze authorized by Porsche.
Checking coolant level
The expansion tank with its filler orifice is on the
left-hand side of 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”
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.
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 container.
Coolant can be deadly to pets if consumed.
1. Switch engine off and let it cool.
Please observe the chapter ”COOLING
SYSTEM” on page 101.
2. Cover the expansion tank cap with a thick
rag. Open cap slowly and carefully and allow
overpressure 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 /-35°C
60% gives protection down to -58°F /-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.
Engine-compartment blower, radiator fan
The radiator and radiator fans are in the front of the
car. The engine-compartment blower is mounted
on the engine compartment lid.
