GMC 22774206 Mount,Engine

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage or wear on driveline components. To check the mounts, the engine must be raised slightly to remove the weight from them. Begin by raising the vehicle and securely supporting it on jackstands, then position a jack under the engine oil pan with a large block of wood between the jack head and the oil pan, carefully raising the engine just enough to relieve the weight on the mounts. Inspect the mounts for any cracks, hardened rubber, or separation from the bushing in the center. Check for any relative movement between the mount and the engine or frame using a large screwdriver or pry bar; if movement is detected, lower the engine and tighten the mount fasteners. When replacing a mount, do not disconnect more than one at a time unless the engine will be removed. Start by disconnecting the cable from the negative terminal of the battery. For the right side mount, remove the air filter housing, then place a large block of wood between the jack head and the oil pan, raising the engine just enough to relieve the weight on the mounts. Remove the engine mount-to-body bolts, followed by the mount-to-engine bracket bolts, and detach the mount from the engine bracket. Installation is the reverse of removal, ensuring to use thread-locking compound on the mount bolts and tightening them securely before reconnecting the battery.

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage to driveline components. During the check, the engine must be raised slightly to remove the weight from the mount. Raise the vehicle and support it securely on jackstands, then position the jack under the engine oil pan with a large block of wood between the jack head and the oil pan, carefully raising the engine just enough to relieve the weight from the mount without fully supporting the engine. Inspect the mount for cracked, hardened rubber or separation from the metal plates, noting that the rubber may split down the center. Check for relative movement between the mount plates and the engine or frame using a large screwdriver or pry bar; if movement is noted, check the tightness of the mount fasteners before condemning the mount, as broken mounts typically allow the engine to move easily when pried or under load. For replacement, ensure the engine transaxle assembly is balanced in weight distribution among the powertrain mounts before tightening the mounting bolts. Loosen all mount bolts, shake the engine side to side and front to rear to settle it, and then tighten the mounts in a specific order. For the right-side mount, remove the engine cover and air filter housing, then raise the vehicle securely on jackstands. For 2009 and earlier 3.6L models, remove the engine mount struts, disconnect the catalytic converter pipe, remove the right front wheel and inner splash shield, and then remove the engine mount-to-subframe nuts. Support the engine with a floor jack and a block of wood, then remove the engine mount bracket bolts and the mount itself. For 3.0L models and 2013 and later 3.6L models, mark the mount location before removal, support the engine, and remove the necessary bolts and nuts to take out the mount. Installation is the reverse of removal, using new fasteners and applying thread-locking compound to the engine mount studs. Engine torque strut mounts for 3.6L models can be replaced without jacking up the engine by removing the through-bolts and the bolts attaching the struts to the radiator support, and alignment may require a pry bar to rotate the engine as needed.

Follow the reverse order of removal and ensure the bolts are tightened to the specified torque.

Loosen the left front wheel lug nuts, raise the vehicle securely on jackstands, remove the left front wheel and inner fender splash shield, support the transaxle with a floor jack, remove the mount bolts, raise the transaxle using the jack, maneuver the mount out, and installation is the reverse of removal with all bolts tightened.

Raise the vehicle and support it securely on jackstands, then position the jack under the engine oil pan with a large block of wood between the jack head and the oil pan, carefully raising the engine just enough to relieve the weight from the mount without fully supporting the engine.

Unbolt the mount from the engine and chassis, then remove it. Installation is the reverse of removal with all bolts tightened.

The right side mount is located at the passenger side (drivebelt end) of the vehicle.
