Cooling System: Service Precautions

Cooling System Components

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, 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.

• When the engine is warm the cooling system is under pressure. If necessary release pressure before commencing repair work.

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

• Pliers for spring clamps (VAS 5024A) or hose clamp pliers (V.A.G 1921) 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).

Perform leak test of cooling system cooling system tester (V.A.G 1274) and adapters (V.A.G 1274/8 ) and (V.A.G 1274/9).
