Cooling system components, removing and installing
WARNING: This page is about a different car, the 2006 Volkswagen Golf, 2005 Volkswagen Jetta, 2005 Volkswagen Golf, 2004 Volkswagen Jetta, and 2004 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
- Route all the various lines (e.g. for fuel, hydraulics, EVAP system, coolant, refrigerant, brake fluid and vacuum) and electrical wiring in their original positions.
- 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 the pressure before beginning repair work.
- Hoses are secured with spring-type clips. In case 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 the hoses stress-free so that they do not come into contact with other components (observe markings on coolant connection and hose).
Check for leaks in cooling system using cooling system tester V.A.G 1274 and adapters V.A.G 1274/8 and V.A.G 1274/9.
