Coolant Level

  • Please see the chapter "EXERCISE EXTREME CAUTION WHEN WORKING ON YOUR VEHICLE" on page 186.

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 located in the rear luggage compartment under the service flap.

  • 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



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.
