UPPER RAD. HOSE CHAFING ON A/C COMPRESSOR BRACKET

VEHICLES AFFECTED: 1987 "F" CAR WITH LG4 5.0L ENGINE AND AIR CONDITIONING

The above vehicles may have the upper radiator hose in hard contact with the screw head of the inboard brace of the A/C compressor bracket, as shown in the Illustration.

To repair this condition loosen the hose clamp at the thermostat housing of the engine and rotate the hose to the right approximately 5 to 10 degrees, as shown in Illustration. This rotation of the hose will give clearance between the hose and the screw head with the hose resting on top of the A/C compressor bracket. Retighten the hose clamp.

Use applicable labour operation number and time.

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.
