ATTENTION: Danger of poisoning!
^ Coolant additives and cleaning liquids are toxic.
--> Swallowing coolant additives and cleaning liquids must be urgently avoided.
--> Do not consume any food or drink while working (danger of accidental mixing).
--> If swallowed, observe the warning information on the containers and contact a doctor. If necessary, show the doctor the warning information on the packaging.
ATTENTION: Danger of scalding with hot coolant!
--> Never open the cooling system when it is hot. Emerging coolant may be very hot and can cause scalding.
--> The cooling system must be depressurised before being opened.
--> Allow engine to cool down.
DANGER: The vehicle fans can continue running or start up automatically.
^ Injuries which can lead to the loss of body parts.
--> The power supply to the fans must be disconnected before starting work on the radiator, radiator fans, or the belt drive.
--> 'Work instructions after disconnecting the battery'
ATTENTION: Risk of damaging the cooling system!
--> Do not relieve the system pressure of the cooling system and then run the engine.
--> Relieving the system pressure and subsequently starting the engine can cause severe damage to components in the cooling system. If the cooling system must be opened when it is hot, allow the cooling system to cool down before starting the engine again.
Note:
^ The coolant filled in at the factory is intended to suffice for the entire service life. As long as the coolant is not contaminated by foreign bodies or other fluids it need not be changed.
^ Different coolant additives must not be mixed and doing so may damage the cooling system. Only use original Porsche coolant additives.
^ The coolant must be set to antifreeze protection of -37°C. This corresponds to a mixing ratio of 50:50 (coolant additive:water). This mixing ratio provides optimum corrosion and antifreeze protection.
^ Coolant additives, coolants and cleaning agents must be disposed of according to the respective, applicable national laws.
^ Seals in the cooling system must be replaced by new ones following disassembly.
Maintenance Cover:
