| Removing and installing parts of cooling system |
WARNING | When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions: |

| t
| Ensure sufficient clearance to all moving or hot components. |
|
Note | t
| When the engine is warm, the cooling system is under pressure. If necessary, release pressure before beginning repair work. |
| t
| Hose connections are secured by spring-type clips. If repair work is carried out, only use spring-type clips. |
| t
| Spring-type clip pliers -VAS 5024- or hose clip pliers -V.A.G 1921- are recommended for installation of spring-type clips. |
| t
| When installing, route coolant hoses tension-free and avoid any contact with other components (note marking on coolant connection and hose). |
