A/C LIQUID LINE RATTLE INSTALL CLAMP ON LIQUID LINE

VEHICLES AFFECTED: J BODY WITH 2.0L ENGINE (VIN CODE 1 AND K)

A noise or rattle condition may occur on some 1987 J cars with the 2.OL engine, Vin Code 1 or K. The noise may be interpreted by the driver as a rattle or buzzing noise coming from the instrument or dash panel area. The noise could be originating with the A/C liquid line vibrating against the emission and purge tubes at the right front of the engine compartment.

To repair the condition, install a clamp on the liquid line as shown in the figure. Use clamp, part number 14036435 and screw part number 11509135, installed in the existing hole at the point indicated.

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.
