Cooling System, Servicing

Cooling system, servicing

CAUTION!
When doing any repair work, especially in the engine compartment, pay attention to the following due to the confined conditions:
^ Route all the various lines (e.g. for fuel, hydraulic system, EVAP system, coolant, refrigerant, brake fluid, vacuum) and electrical wiring so that the original positions are restored.
^ Ensure that there is 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. In case of repair, only use spring-type clips.





^ To install spring-type clips spring type clip pliers VAS 5024 A or hose clamp pliers V.A. G 1921 are recommended.
^ 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 a leak test of the cooling system with cooling system tester V.A.G 1274 and adapters V.A.G 1274-8 and V.A.G 1274-9.
