Checking Cooling System

Engine maintenance: Checking cooling system

Coolant: Checking the level and antifreeze protection content







1. Protect the luggage compartment floor against soiling with a suitable cover.

NOTE:
- The engine cooling system is factory-filled with a coolant which does not need to be changed. The coolant should not be mixed with other coolants
- Only Original Porsche anti-freeze should be used when changing or topping up the coolant.
- A conclusion about the anti-freeze content can not be made on the intensity of the coolant colour in the expansion tank.

CAUTION:
- Danger of scalding
- Coolants can be extremely hot and pressurized.
- Wear suitable protective equipment.
- Carefully open the lid on the expansion tank.







2. Carefully undo the lid on the coolant expansion tank.
3. Check the anti-freeze content with a frost protection testing device. If it is lower than - 35 degrees C it should be corrected accordingly.







4. Check the engine coolant level. This should not lie below the minimum marking when cold.







5. Check the cooling system for leaks. To do this, apply a test pressure of approx. 1 bar using the cooling system test device and check the hose connections for leakage or tighten the screw hose clamps. Subsequently remove the cooling system test device.







6. Check cooling device for external dirt. The cooling device should not contain too much dirt. If necessary, it can be cleaned with a vacuum cleaner.







7. Replace the cover on the coolant expansion tank and tighten.
