GMC 15854396 Adapter,Engine Mount Bracket

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately or the added strain placed on the driveline components may cause damage or wear. During the check, the engine must be raised slightly to remove the weight from the mounts. Raise the vehicle and support it securely on jackstands, then position a jack under the engine oil pan. Place a large block of wood between the jack head and the oil pan, then carefully raise the engine just enough to take the weight off the mounts. Check the mounts to see if the rubber is cracked, hardened or separated from the bushing in the center of the mount. Check for relative movement between the mount and the engine or frame (use a large screwdriver or prybar to attempt to move the mounts). If movement is noted, lower the engine and tighten the mount fasteners. For replacement, disconnect the negative battery cable from the battery. On all engines except the 2.0L supercharged, remove the engine air filter and housing. Raise the vehicle and support it securely on jackstands. Place a large block of wood between the jack head and the oil pan, then carefully raise the engine just enough to take the weight off the mounts. Caution: Do not disconnect more than one mount at a time unless the engine will be removed from the vehicle. Remove the engine mount through-bolt/nuts and detach the mount from the chassis bracket. Remove the nuts holding the mount to the engine bracket. Installation is the reverse of removal. Use thread-locking compound on the mount bolts and be sure to tighten them securely. The engine/transaxle assembly must be "balanced" in its weight distribution among the several powertrain mounts, before the mounting bolts are tightened. Loosen all the mount bolts, then shake the engine from side to side and front-to-rear as much as possible to settle it. The tighten all the mounts in this order: transmission mount-to-transmission bolts (rear first, then middle, then front); engine mount-to-bracket bolts (center first); shake the engine again front-to-rear; rear mount through-bolt; then front mount through-bolt. Reconnect the battery.

Raise the vehicle and support it securely on jackstands, then use a floor jack with a block of wood to solidly support the engine under the oil pan. The right side mount is located at the passenger side (drivebelt end) of the vehicle; begin by removing the air filter housing. Unbolt the mount from the engine bracket and the vehicle frame, then remove it, ensuring the engine is supported either by an engine support fixture or a padded jack placed under the oil pan. For installation, follow the reverse order of removal and tighten the bolts to the specified torque. To address the front and rear mounts, remove the mount through-bolt to disconnect the front engine mount from the frame bracket, noting that the rear mount is similar. Next, remove the bolts from the transmission and then take out the mount. For installation, again follow the reverse order of removal and ensure the bolts are tightened to the specified torque.

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.

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.

Reconnect the battery.

Again, install an engine support fixture and connect the chains, or support the engine/transaxle from below. For AWD models, loosen the front wheel lug nuts, raise the vehicle securely on jackstands, remove the front wheels, disconnect the stabilizer bar from its links, and rotate it up for access. Then, remove the through-bolt from the rear mount, unbolt it from the frame, and remove it. Installation is the reverse of removal with all bolts tightened.

Installation is the reverse of removal. Use thread-locking compound on the mount fasteners and ensure they are tightened securely.

Ensure the transaxle does not move excessively away from the mount; if it does, replace the mount.

To replace the front transaxle mount, remove the battery and associated components. Then, raise the vehicle and support it securely. Remove the battery tray and disconnect necessary wiring. Unbolt the mount from the frame and engine, then separate the mount from its bracket. Installation is done by reversing the removal steps.
