Cooling System Components, Removing and Installing

Cooling system components, removing and installing

WARNING:
When doing any repair work, especially in the engine compartment, due to the cramped conditions, pay attention to the following:
^ Route all sorts of hoses/lines (e.g. for fuel, hydraulics, evaporative emissions system, coolant, refrigerant, brake fluid and vacuum pipes and hoses) and 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 commencing repair work.
^ Hoses are secured with spring-type clips. In cases of repair only use spring-type clips.
^ VAG1921 pliers are recommended when 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.
^ Parts of cooling system body side.
^ Parts of cooling system engine side.
^ Coolant hose connection diagram.
^ Draining and filling with coolant.
^ Coolant mixture ratios.
