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.

  • 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.


  • Check coolant level.
    If necessary, add coolant and have fault remedied at an authorized Porsche dealer.
    Please see the chapter "COOLANT LEVEL" on page 181.

Information
To prevent excessive temperatures, the cooling-air passages must not be restricted by coverings (e.g. films, "stone guards").


If the coolant level is too low, the warning light flashes.

Additionally, a warning is displayed in the on-board computer.

  • Switch engine off and allow to cool.
  • Add coolant after the engine has cooled to the touch.
  • Have the cause of the fault remedied at an authorized Porsche dealer.
    Please see the chapter "COOLANT LEVEL" on page 181.
