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 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 cases of repair only use spring-type 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 VA G 1274/8 and VA G 1274/9.
