Engine - Vibration

Number: 85-175

Section: 6

Date: FEB., 1986
Subject: ENGINE VIBRATION


Model and Year: 1985 CELEBRITY MODEL VEHICLES WITH 2.5L L4 ENGINE VIN CODE R


TO: ALL CHEVROLET DEALERS


Some 1985 Celebrity models equipped with a 2.5L engine and a 125C transaxle may exhibit a vibration in the steering wheel, instrument panel, seat and floor at 55-70 mph under light throttle. The vibration will disappear when the brake pedal is applied. This condition may be due to the alternator belt. Replacing the cogged alternator belt with a non-cogged alternator belt, part number 22514316 may eliminate this condition.
