Model/Year:
1996 C/K TRUCKS WITH HEAVE DUTY EXHAUST EMISSIONS

To: All Chevrolet/Geo Dealers

General Motors has decided that some 1996 C/K Pickups and Chassis-Cabs with 5.7L (L31) or 7.4L (L29) gasoline engines and heavy duty exhaust emissions may have been built with catalytic converters that were welded into the exhaust pipe backwards. In this configuration, the engine may not meet the configuration specified in the emissions Application for Certification.

To correct this condition, dealers will inspection to see if the catalytic converter is installed in the proper orientation. If not, the exhaust crossover pipe assembly will be replaced.
