| General instructions for charge air system |
WARNING | When undertaking all installation work, particularly in the engine compartment because of its cramped construction, please observe the following: |
| t
| Lay lines of all kinds (e.g. for fuel, hydraulic fluid, cooling fluid and refrigerant, 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, air filter insert and charge air hoses as well as charge air pipes for soiling. |
| t
| Check all the air guides and the charge air cooler for foreign bodies. |
| If foreign bodies are detected in the charge air system, the complete charge-air routing must be cleaned and if necessary the charge air cooler must also be replaced. |
|
| t
| The charge-air system must be tight, check → Chapter. |
| t
| Replace the gaskets, the sealing rings and the self-locking nuts. |
| t
| Hose connections and hoses of the charge air system must be free of oil and grease before being installed. |
| t
| Observe assembly markings on the hoses and components. |
| t
| All hose connections of the charging system are secured with screw clamps. |
| t
| Observe the instructions for installing the charge air hoses and tightening torques of the screw clamps → Chapter. |
| t
| Before screwing down the oil feed line, fill the exhaust turbocharger via the connection fitting with engine oil. |
| t
| After installing the exhaust turbocharger, run engine at idling speed for about 1 minute to ensure that oil is supplied to the turbocharger bearing. |
