^ Wear protective gloves.

Caution: Danger of poisoning!
^ Materials used during installation work, such as silicones, greases and oils, are toxic and must not be swallowed.
^ Observe the specifications on the containers. If swallowed, seek medical advice and show the information on the containers.

Note:
^ When working on the crankshaft, absolute cleanliness is essential.
^ Any seals which have been removed must always be replaced.
^ Only the auxiliary and assembly equipment recommended for the repair may be used for the particular assembly work.
^ Only the auxiliary materials recommended by Porsche (such as lubricants or sealants) may be used.
^ All screw fittings must be tightened according to the prescribed torque or torque angle.

Group 13- Crankshaft, pistons

Caution: Danger of poisoning!
^ Materials used during installation work, such as silicones, greases and oils, are toxic and must not be swallowed.
^ Observe the specifications on the containers. If swallowed, seek medical advice and show the information on the containers.

Note:
^ Work on the crankshaft pistons must be carried out very carefully and in clean conditions.
^ A dirty engine should be cleaned before opening.
^ No dirt may enter the engine when opened.
^ During interruptions in work, the open engine or components must be covered to protect them from dirt.
^ Any seals which have been removed must always be replaced.
^ Only processing materials (silicones, oils and greases, etc.) approved by Porsche may be used.
^ All screw fittings must be tightened according to the prescribed torque or torque angle.

Caution: Danger of injury!
^ Never reach into running drive belt or rotating components.

Warning: Risk of damage!
^ Never remove the drive belt when it is hot.
^ If the drive belt is removed when it is hot, it can be deformed and damaged.

Caution: Danger of injury!
^ The vehicle fares can continue running or start up automatically.
^ The power supply to the fares must be disconnected before starting work on the radiator, radiator fan or drive belt.

Note:
^ Only auxiliary materials (silicones, oils and greases, etc.) approved by Porsche may be used.
^ All screw fittings must be tightened according to the prescribed torque or torque angle.
^ Never remove the drive belt when it is hot.

Group 15 - Cylinder head, valve drive

Caution: Danger of poisoning!
^ Auxiliary materials used during installation work, such as silicones, greases and oils, are toxic and must not be swallowed.
^ Observe the specifications on the containers. If swallowed, seek medical advice and show the information on the containers.

Note:
^ Work on the valve drive must be carried out very carefully and in clean conditions.
^ A dirty engine should be cleaned before opening.
^ No dirt may enter the engine when opened.
^ During interruptions in work, the open engine or components must be covered to protect them from dirt.
^ Any seals which have been removed must always be replaced.
^ Only the auxiliary materials recommended by Porsche (such as lubricants or sealants) may be used.
^ All screw fittings must be tightened according to the prescribed torque or torque angle.

Group 17 - Lubrication

Caution: Danger of poisoning!
^ Engine oil is toxic.
^ If swallowed, observe the warning information on the containers, contact a doctoral necessary and show the information on the containers.

Caution: Danger of scalding!
^ Engine oil and components of the oil circuit can become very hot!
^ Avoid contact with the skin and eyes.
^ Wear suitable protective clothing.

Warning: Danger of fire!
^ Do not pour engine oil over very hot components (e.g. turbocharger).
^ Never place cloths soaked with oil on hot engine components.
^ In the case of fire, use CO2 or dry powder fire extinguishers.

Note:
^ Only oils with the appropriate viscosity and approved by Porsche may be used.
^ A mixture of different oils is not permitted.
^ During an oil change, the old oil must be drained from the engine via the drain plugs provided. Extraction by suction is not recommended.
^ Engine oil and oil filters must be disposed of according to the respective, applicable national laws. Seals in the oil circuit must be replaced by new ones following disassembly. Observe the torques specified.

Group 19- Cooling

Caution: Danger of poisoning!
^ Coolant additives and cleaning liquids are toxic.
^ If swallowed, observe the warning information on the containers and contact a doctor. If necessary, show the doctor the warning information on the packaging.

Caution: Danger of scalding!
^ Never open the cooling system when it is hot. Arty escaping coolant may be very hot and can cause scalding.
^ The cooling system must bedepressurizee before being opened.

Caution: Danger of injury!
^ The vehicle fares can continue running or start up automatically.
^ The power supply to the fares must be disconnected before starting work on the radiator or radiator fan.

Warning: Risk of damage!
^ Do not relieve the system pressure of the cooling circuit and then run the engine.
^ Relieving the system pressure and subsequently starting the engine can lead to severe damage to components in the cooling circuit. If the cooling circuit must be operated 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.
^ It is not permitted to mix different coolant additives and doing so may lead to damage to the cooling circuit. Use only original Porsche coolant additives.
^ The coolant must be set to an antifreeze protection of -37°C. This corresponds to a mixing ratio of 50:50 (coolant additive: water). This mixture provides the optimum corrosion and frost protection.
^ Coolant additives, coolants and cleaning liquids must be disposed of according to the respective, applicable national laws.
^ Seals that have been removed in the oil circuit must be replaced by new ones.
