| Removing and installing parts of cooling system |
Caution | When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions: |
| t
| All conduits (for example for fuel, hydraulics, carbon filter, liquid cooler and cooling agent, brake fluid, low pressure) and the electric cables must be placed in such a way that they return to their original position. |
| t
| Ensure that there is 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
| hose connections are secured with spring-type clips. In case of repair, only use spring-type clips. |
| t
| For fitting spring-type clips, it is advisable to use pliers -T20029- or pliers -T20174-. |
| t
| When installing, route coolant hoses without tension and not touching other components (note marking on coolant connection and hose). |
| Verifying the cooling system seal: check with the coolant system tester -SAT 1274-, adapter -VAG 1274/8- and adapter -VAG 1274/9- → Chapter. |
