CATALYTIC CONVERTER ODOR (NEW CATALYTIC CONVERTER P/N)

MODELS: 1988/1989 S/T TRUCKS WITH 2.8L (VIN CODE R) ENGINE

THIS BULLETIN CANCELS GMC TSB 88-T-144. THIS BULLETIN IS BEING UPDATED TO ADD AN ADDITIONAL MODEL YEAR AND CHANGE THE PART NUMBER OF THE CONVERTER.

Some 1988 and early built 1989 S/T trucks with a 2.8L engine may exhibit a higher than normal catalytic converter odor during operation. This odor condition can be reduced by installing catalytic converter, P/N 25104271. A new converter with nickel will enter production in the near future. VIN break-points were not available at the time of publication. Parts are expected to be ava il able on January 1, 1989. Until then, normal parts orders will not be accepted by GMSPO. Only verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be cancelled as incorrectly ordered while the 400 control is in place.

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.
