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.
Checking coolant level
The expansion tank with its filler orifice is located in the rear luggage compartment under the service flap.
When the engine is cold and the car is level the fluid level must lie between the "MIN" and "MAX" markings.
Topping off coolant
Hot Engine Coolant
Coolant gets very hot when the engine is running. The coolant reservoir is pressurised. Hot coolant can spray out suddenly if the coolant reservoir is opened without due care.
Swallowing Engine Coolant
Coolant is hazardous to health. Coolant can be deadly to children or pets if consumed.
Risk of damage from overflowing coolant.
Antifreeze in coolant:
50% gives protection down to –31 °F/–35 °C
60% gives protection down to –58 °F/–50 °C
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.
