Procedures
Checking cooling systemCoolant - check antifreeze and fluid level
Note: The coolant filled in at the factory is intended for lifetime cooling and, thus, need not be changed.
1. Open cap on coolant expansion tank.
WARNING: Coolant is corrosive and hazardous to health.
^ Skin and eye irritation
^ Wear protective gloves and goggles.
^ If you come into contact with coolant, wash off immediately with plenty of warm water.
ATTENTION: Mixing coolant.
^ Corrosion of components and flocculation of coolant
^ Do not mix Porsche coolant with other coolants.
^ When replacing or topping up coolant, use only original Porsche coolant (see Porsche Parts Catalogue).
2. Check antifreeze content with a commercially available antifreeze tester. If this is below - 35°C, correct the anti-freeze content by raising the proportion of pure coolant accordingly. ;
3. Screw on cap and tighten it. Do not tilt lid.
Checking On cooling system for leaks
WARNING: Danger of scalding from hot pressurized coolant.
^ Only work on the coolant system when the engine is "cool".
^ Wear protective gloves and goggles.
1. Open cap on coolant expansion tank.
2. Check the cooling system for leaks. To do this, apply a test pressure of approximately 1 bar using the cooling system test device and check hose connections for leakage .
3. Screw on cap and tighten it. Do not tilt lid.
Cleaning the cooling air guides
ATTENTION: Soiling and damage to radiator surface (vanes).
^ Engine overheating due to lack of cooling performance.
^ Clean radiator surface regularly.
^ Do not use a high-pressure steam cleaner to clean it.
1. Check cooling air guides and radiator for foreign bodies such as leaves. If necessary, carefully clean the cooling air guides and radiator surfaces at the front using a vacuum cleaner with a single nozzle, see Vacuum cleaner nozzle, long crevice tool for cleaning cooling air inlet shafts NR.160.If a high-pressure steam cleaner is used, the steam jets can cause additional particles of dirt to attach to the radiator surface and the cooling vanes can be bent. The engine becomes overheated due to lack of cooling performance.
