| 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
| Route all the various lines (e.g. for fuel, hydraulics, activated charcoal filter system, coolant and refrigerant, brake fluid and vacuum) and electrical wiring in their original positions. |
| t
| Ensure that there is 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
| Hoses are secured with spring-type clips. In case of repair, only use spring-type clips. |
| t
| Spring-type clip pliers -VAS 5024A- or hose clip pliers -V.A.G 1921- are recommended for installation of spring-type clips. |
| t
| 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). |
| Test for leaks in cooling system using cooling system tester -V.A.G 1274- and adapter for cooling system tester -V.A.G 1274/8- and adapter for cooling system tester -V.A.G 1274/9-. |
