Cooling System: Service and Repair: Overview

Cooling system components, removing and installing

Note:
^ * When the engine is warm the cooling system is under pressure. If necessary release pressure before starting repair work.
^ Hoses are secured with spring-type clips. In cases of repair only use spring-type clips.
^ VAS 5024 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 VAG 1274 and adapters VAG 1274/8 and VAG 127419.
