Cooling System Components, Removing and Installing

Cooling system components, removing and installing

CAUTION: When performing repair work, especially due to the confined conditions in the engine compartment, pay attention to the following:
^ Route all types of hoses/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 the pressure before beginning repair work.
^ Hoses are secured with spring-type clips. In case of repair, only use spring-type clips.
^ Assembly tool VAS5024 or hose clip pliers VAG1921 are recommended for installing spring-type clips.
^ When installing coolant hoses, route 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 VAG1274 and adapters VAG1274/8 and VAG1274/9.
