CAMPAIGN:LOOSE FUEL TANK ATTACHMENT. Buick Coachbuilder 1994

For 1990-2009 cars

# CAMPAIGN:LOOSE FUEL TANK ATTACHMENT

U.S. Campaign Number Cross Reference

Chev Buick Cadillac 94-C-54 94-C-54 94-C-54

#### Models: 1994 Chevrolet Caprice 1994 Buick Roadmaster 1994 Cadillac Fleetwood

#### TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1994 Chevrolet Caprice, Buick Roadmaster and Cadillac Fleetwood model vehicles. These vehicles were shipped with fuel tank attachment strap fasteners below the specified torque. Under normal operating conditions, these "loose" fasteners could, in time, become completely detached. As the fasteners become detached, the operator may notice the fuel tank strap sagging below the normal vehicle silhouette, or while driving, may hear a "clunking" noise. If the operator was never alerted by these warnings, eventually the fuel tank could sag down to the point of striking something in the road or the road surface. This could result in fuel tank leak and possible under-vehicle fire.

To correct this condition, dealers are to torque the fuel tank strap fasteners to the proper specifications.

#### VEHICLES INVOLVED:

Involved are certain 1994 Chevrolet, Buick and Cadillac model built within the following VIN breakpoints:
