Clean Working Conditions

Even minor contaminations can lead to malfunctions in the fuel injection system. When working on coolant supply and fuel injection system, observe the following rules of cleanliness:

• Before loosening, connections and surrounding areas must be cleaned thoroughly with engine or brake cleaner, and then cleaned area must be dried completely.

• Immediately seal off lines and connections with clean plugs or protective caps.

• Place removed parts on a clean surface and cover them with lint-free cloths.

• Only install clean components: Only unpack replacement parts immediately prior to installation. Do not use parts that have been stored unpackaged (e.g. in tool boxes etc.).

• If system is open, do not work with compressed air and do not move the vehicle.

• Protect disconnected electrical connectors from dirt and moisture and only connect if dry.
