| Carefully observe the following „6 rules“ for cleanliness when working on the fuel supply/injection system: |
| t
| Thoroughly clean the connection points and their surroundings before releasing. |
| t
| Place removed parts on a clean surface and cover with a clean cloth. Do not use fuzzy cloths! |
| t
| Carefully cover or close opened components if the repair is not completed immediately. |
| t
| Only install clean parts. Remove spare parts from their wrapping immediately before fitting. Do not use any parts which have been stored unwrapped (e.g. in tool boxes etc.). |
| t
| If the system is opened, avoid working with compressed air and avoid moving the vehicle. |
| t
| Also make sure no diesel fuel runs onto the coolant hoses. If this is the case clean the hoses immediately. Contaminated hoses must be replaced. |
