Cooling System Components, Removing and Installing

Cooling system components, removing and installing

WARNING!
When performing repair work, especially due to the confined conditions in the engine well, pay attention to the following:
^ Route all types of lines (e.g. for fuel, hydraulics, EVAP system, coolant, refrigerant, brake fluid and vacuum) as well as electrical wiring so that the original positions are restored.
^ Ensure sufficient clearance to all moving or hot components.

Note:
^ When the engine is warm the cooling system is under pressure. If necessary release pressure before beginning repair work.
^ Hoses are secured with spring-type clips. When repairing only use spring-type clips.
^ Always replace clamp-type clips with springtype clips. Assembly tool VAS 5024 or hose clip pliers V.A.G. 1921 are recommended for installing spring-type clips.
^ When installing coolant hoses route them stress-free so that they do not come into contact with other components (observe markings on coolant connection and hose).

Perform cooling system leakage test with cooling system tester V.A.G. 1274 and adapters V.A.G. 1274/8 and V.A.G. 1274/9
