Cooling System: Service Precautions

Cooling System Components

CAUTION!
Risk of scalding due to hot steam and hot coolant:

• When the engine is warm the cooling system is under pressure.

• Wear protective goggles and protective clothing to prevent damage to eyes and scalding.

• Reduce the pressure by covering the coolant reservoir cap with a rag and opening it carefully.

CAUTION!
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

• Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.

• Ensure sufficient clearance to all moving or hot components.

• Secure all hose connections using hose clamps appropriate for the model type.

• Hoses are secured with spring-type clips. In cases of repair only use spring-type clips.

• Pliers for spring clamps (VAS 6362) or hose clamp pliers (VAS 6340) are recommended for installing spring clamps.





• When installing coolant hoses, make sure they are free of stress and do not come into contact with other components (observe markings on coolant connections and hoses).
