MOAN NOISE AT IDLE, A/C ON POWER STEERING PUMP DRIVE BELT

VEHICLES AFFECTED: 1986 C Cars

Some early production 1986 Electras and Park Avenues may have a moan-type noise, noticeable at curb idle in 'drive' with the A/C compressor operating. To reduce or minimize this condition, a new power steering pump drive belt tensioner brace ('Y'-shaped brace replaced the 'L'-shaped brace) was added in production. Refer to illustration. If an owner should comment of this condition, obtain the new brace number 25529079 and one bolt number 14081734 from GM Parts Department and install as shown in illustration.

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.
