MFI Turbo Engine, Campaign Label, Replaced Parts & Information

MFI TURBO ENGINE (RPO LT3, VIN CODE M)

1. CAUTION: To reduce the risk of fire and personal injury, it is necessary to relieve fuel system pressure before servicing fuel system components. Have a dry chemical (Class B) fire extinguisher near work area.

To relieve the fuel system pressure do the following:

- Remove "Fuel Pump" fuse from fuse block in passenger compartment.

- Crank engine. Engine will start and run until fuel supply remaining in fuel lines has been consumed. Engage starter for 3.0 seconds to assure relief of any remaining pressure.

Unless this procedure is followed before servicing fuel lines or connections, fuel spray could occur.

2. Disconnect negative battery cable.

3. Use a backup wrench when loosening the screw coupling fittings at fuel line ends.

CAMPAIGN IDENTIFICATION LABEL

Each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label." Each label provides a space to include the campaign number, the five (5) digit dealer code of the dealer performing the campaign service and the date the vehicle was campaigned. This information may be inserted with a typewriter or a ballpoint pen. Install the label only on a clean, dry surface of the radiator baffle where it is readily visible.

Replaced parts must be held for disposition by Buick Field or Branch contact personnel. Parts must have a claim tag attached showing the repair order and the VIN of the vehicle from which they were removed.
