| Removing and installing parts of cooling system |
Caution | t
| When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions: |
| t
| All the various lines (e.g. fuel, hydraulic system, active carbon filter system, coolant, refrigerant, brake fluid and vacuum pipes and hoses) and electrical wiring must be installed in their original positions. |
| t
| To avoid damage to lines/wiring, ensure sufficient clearance to all moving or hot components. |
|
Note | t
| When the engine is hot the cooling system is under pressure. If necessary, relieve pressure before commencing repair work. |
| t
| Hoses are secured with spring-type clips. In case of repair, only use spring-type clips. |
| t
| To fit spring-type clips, hose clip pliers -VAS 6340- or spring-type clip pliers -VAS 5024A- are recommended |
| t
| Coolant hoses should be free from tension when installing, 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 B- and adapter for cooling system tester -V.A.G 1274/8- and adapter for cooling system tester -V.A.G 1274/9-. |
