CAMPAIGN: POWER STEERING HOSE ROUTING. Oldsmobile Omega 1981

CONDITION

GENERAL MOTORS HAS DETERMINED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN SOME 1981 OLDSMOBILE OMEGA MODELS EQUIPPED WITH A V6 ENGINE AND POWER STEERING. THE INVOLVED VEHICLES MAY HAVE BEEN ASSEMBLED WITH THE POWER STEERING HOSE(S) INCORRECTLY ROUTED. IF THIS CONDITION IS NOT CORRECTED THE POWER STEERING HOSE MAY CONTACT THE EXHAUST MANIFOLD, RESULTING IN POSSIBLE DETERIORATION OF THE HOSE. HOSE FAILURE WOULD RESULT IN POWER STEERING FLUID LEAKAGE ONTO THE EXHAUST MANIFOLD. UNDER CERTAIN CONDITIONS SMOKE AND/OR AN UNDERHOOD FIRE COULD THEN RESULT. SUCH A FIRE COULD, IN TIME, SPREAD TO THE PASSENGER COMPARTMENT AND CAUSE BURN INJURIES TO OCCUPANTS REMAINING IN THE VEHICLE.

CARS AFFECTED

CERTAIN 1981 OLDSMOBILE OMEGA MODELS EQUIPPED WITH V6 ENGINE AND POWER STEERING BUILT AT WILLOW RUN (W) ASSEMBLY PLANT FROM THE START OF PRODUCTION UP TO AND INCLUDING THE FOLLOWING VIN:

BW109869

DEALER ACTION

DEALERS ARE TO INSPECT AND REPLACE THE POWER STEERING HOSE(S) AS REQUIRED.

ON CARS EQUIPPED WITH AIR CONDITIOING THE POWER STEERING PRESSURE HOSE IS TO BE REPLACED AND THE RETURN HOSE IS TO BE INSPECTED FOR PROPER CLEARANCE AND REPLACED IF NECESSARY. (REFER TO THE SERVICE PROCEDURE FOR AIR OCNDITIONED CARS.)

ON NON AIR CONDITIONED CARS THE PRESSURE AND RETURN HOSES ARE TO BE INSPECTED FOR PROPER CLEARANCE AND REPLACED IF NECESSARY. (REFER TO THE SERVICE PROCEDURE FOR NON AIR CONDITIONED CARS.)

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.
