SUBJECT: INSUFFICIENT TORQUE - ENGINE MOUNT STRUT BRACKET TO ENGINE FASTENERS
CANADA ONLY
Models: 1995 Chevrolet Cavalier and Pontiac Sunrire Models Equipped with 2.2L Engines (RPO LN2)
TO: ALL GENERAL MOTORS DEALERS
General Motors of Canada Limited has determined that CERTAIN 1995 Chevrolet Cavalier and Pontiac Sunfire model vehicles may have been built with insufficient torque applied to the fasteners which attach the engine mount strut bracket to the engine. This may result in these fasteners becoming loose, allowing movement of the engine mount strut bracket relative to the engine. This movement could result in noise which may be audible to the vehicle occupant(s).
To correct this condition, dealers will tighten the involved fasteners to specified torque levels.
