CAMPAIGN: POWER STEERING INLET HOSE

SUBJECT: POWER STEERING GEAR INLET HOSE

MODELS: 1992-93 Chevrolet LT1 Corvette

TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain late 1992 and early 1993 Chevrolet Corvette model vehicles equipped with LT1 engines. These vehicles were assembled with a power steering gear inlet hose which may fracture. Since the fluid within this hose is under pressure, fracture of the hose could cause power steering fluid to spray out of the hose and, if an ignition source is present, an engine compartment fire could occur.

To prevent this condition from occurring dealers are to replace the power steering gear inlet hose on involved vehicles.

VEHICLES INVOLVED:

Involved are CERTAIN late 1992 and early 1993 Chevrolet Corvette model vehicles built within the following VIN breakpoints:

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
