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.
