Parking/Auxiliary Heater And Fuel System Clean Working Conditions

Follow these five "rules" when working on the fuel supply/injector system:

• Always clean the connection locations and the area around them before loosening.
• Place removed parts on a clean surface and cover them. Use a lint-free cloth.
• Carefully cover or plug unpacked components if repairs cannot be performed immediately.
• Only install clean components: Remove the replacement parts from their packaging just prior to installing them. Do not use parts that have been stored loose (for example, in tool boxes etc.).
• When the system is open: do not work with compressed air.
• Do not move vehicle.
• Seal off any open lines and connections immediately with plugs, for example, take from Engine Bung Set :VAS6122  .
• Protect the disconnected connectors from dirt and moisture and only connect when they are dry.
