| General instructions for charge air system |
WARNING | Please observe the following when undertaking all assembly work, particularly in the engine compartment, due to its cramped construction. |
| t
| Lay lines of all kinds (e.g. for fuel, hydraulic fluid, cooling fluid and refrigerent, brake fluid, vacuum) and electrical lines in such a way that the original line guide is re-established. |
| t
| Ensure that there is adequate free access to all moving or hot components. |
|
Caution | In case a mechanical damage to the exhaust gas turbocharger is found, e.g. damage to the compressor wheel, it is not sufficient to only replace the turbocharger. In order to avoid consequential damage, perform the following tasks: |
| t
| Change engine oil and oil filter. |
| t
| Check air filter housing, air filter element and charge air pipes as well as charge air hoses for soiling. |
| t
| Check all air guides and charge air cooler for foreign bodies. |
| If foreign bodies are detected in the charge air system, the charge-air routing must be cleaned and the charge air cooler must be replaced. |
|
| t
| The charge-air system must be tight, check → Chapter. |
| t
| Always replace self-locking nuts. |
| t
| Hose connections and hoses for charge air system must be free of oil and grease before being installed. The gasket ring and the sealing surface must be slightly oiled only for push-fit couplings → Chapter. |
| t
| Observe assembly markings on the hoses and components. |
| t
| All hose connections of the charge air system are secured with spring strap clamps or push-fit couplings. |
| t
| Use pliers for spring strap clamps to fit the spring strap clips. |
| t
| Assembly of hose connections with push-fit couplings → Chapter. |
| t
| Before screwing on the oil feed line, fill the exhaust gas turbocharger on the connection fitting with engine oil. |
| t
| after installing the exhaust gas turbocharger run the engine approx. 1 minute in idle and do not increase speed immediately in order to ensure the supply of oil to the exhaust gas turbocharger. |
