WARNING
|
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 | Hose clip pliers -VAS 6340- are recommended to install 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 expansion tank -V.A.G 1274/8- and adapter for sealing cap -V.A.G 1274/9-. |
Note| As of week 22/09 a 4/2-way valve has been introduced; this contains the thermostat and ensures an improved flow of coolant through the cylinder head. Schematic diagram for vehicles with 4/2-way valve → Chapter. |
