Turbocharger, Removing And Installing, Vehicles With A Turbocharger: Removing
When working on the whole exhaust system:
- Follow the safety precautions when working on the exhaust system.
If mechanical damage (such as a destroyed compression wheel) is found on the turbocharger, just replacing the turbocharger is not enough. To avoid damage later, perform the following steps:
- Check the air filter housing, air filter element and air guide hoses for contamination.
- Possible cause for mechanical fault in the turbocharger can be foreign objects from the exhaust manifold.
- Check the entire charge air circuit and charge air cooler for foreign objects.
- If there are foreign objects in the charge air system, clean the charge air circuit and replace the charge air cooler if necessary.
Follow all the rules of cleanliness.
