| General instructions for charge air system |
WARNING | When undertaking all installation work, particularly in the engine compartment due to 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
| Inspect the air filter housing, the air filter element and the intake hoses for contaminations. |
| t
| Inspect the whole charge-air routing 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. |
| 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
| Assembly of hose connections with push-fit couplings → Chapter. |
| t
| Observe markings on the hoses and components. |
| t
| Use pliers for spring strap clamps to fit the spring strap clips. |
| t
| Before screwing on the oil feed line, fill the exhaust gas turbocharger on the connection fitting with engine oil. |
| t
| After installing the turbocharger, run engine at idling speed for about 1 minute to ensure that oil is supplied to the turbocharger. |
