CAMPAIGN: A/C EVAP. PIPE AND DIPSTICK TUBE INTERFERENCE

GENERAL MOTORS HAS DETERMINED THAT SOME 1980 CAMAROS EQUIPPED WITH AIR CONDITIONING MAY HAVE INTERFERENCE BETWEEN THE A/C EVAPORATOR CORE ALUMINUM INLET PIPE AND THE ENGINE OIL STEEL DIPSTICK TUBE ASSEMBLY. AS A RESULT, THE ALUMINUM INLET PIPE MAY WEAR THROUGH AT THE POINT OF CONTACT WITH THE DIPSTICK TUBE ASSEMBLY.

TO CORRECT THIS CONDITION, DEALERS ARE TO INSPECT AND, IF REQUIRED, REPOSITION THE A/C EVAPORATOR PIPE. ALSO, REPLACE THE EVAPORATOR CORE AND INLET PIPE ASSEMBLY ON THOSE VEHICLES WHERE THE INTERFERENCE CONDITION HAS CAUSED A REFRIGERATION LEAK.

INVOLVED ARE CERTAIN 1980 CHEVROLET CAMARO MODELS EQUIPPED WITH RPO C60 AND EITHER V6 OR V8 ENGINES EXCEPT THE LD5 (231 CUBIC INCH V6) WITHIN THE FOLLOWING VEHICLE 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.
