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 cramped conditions:
^ All the various lines (e.g. for fuel, hydraulic system, EVAP system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring are to be installed in the original way.
^ 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 stress-free so that they do not come into contact with other components (observe markings on coolant connection and hose).

Perform leak test of cooling system with cooling system tester V.A.G 1274 and adapters V.A.G 1274/8 and V.A.G 1274/9.
