Cooling System Components, Removing And Installing: Notes

WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2006 Volkswagen GTI, 2005 Volkswagen Jetta, 2005 Volkswagen GTI, 2004 Volkswagen Jetta, and 2004 Volkswagen GTI. However, it is still accessible from the selected car via links, so may be relevant.

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 lines (e.g. for fuel, hydraulics, evaporative emissions system, coolant, refrigerant, brake fluid and vacuum lines and hoses) and electrical wiring so that the original positions are restored.
Make sure 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.
Assembly tool VAS 5024 or hose clip pliers V.A.G. 1921 are recommended for 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 V.A.G. 1274 and adapters V.A.G. 1274/8 and V.A.G. 1274/9.
