GM 10185131 Bracket, Engine Front Mount

Start by removing the through-bolt and nut. Then, raise the engine slightly using a hoist or jack with a wood block under the oil pan, and remove the mount and bracket assembly from the frame. Install the new mount along with the through-bolt and nut, ensuring all bolts are tightened to the specified torque.

To inspect the rear mount, elevate the vehicle and push up and down on the transmission tailshaft while observing the mount. If the rubber separates from the metal plate or the tailshaft moves excessively, replace the mount. If there is movement between the mount's metal plate and the attachment point, tighten the bolts or screws.

To slow deterioration, apply rubber preservative to the mounts.

Check the mounts for cracked, hardened, or separated rubber, and look for any relative movement between the mount plates and the engine or frame, using a large screwdriver or pry bar to test for movement.

For replacement, detach the negative battery cable and remove the upper torque strut bracket bolt, ensuring the Theftlock audio system's lockout feature is off if applicable. Remove the torque strut-to-body mount bolts and the torque strut itself, then position the new torque strut and install the bolts, tightening them securely before reconnecting the negative battery cable.

To check the mounts, the engine must be raised slightly to relieve weight from them. Begin by raising the vehicle and securely supporting it on jack stands, then position a jack under the engine oil pan with a large block of wood in between. Carefully raise the engine just enough to take the weight off the mounts, ensuring no part of the body is placed under the engine when it is only supported by a jack. Inspect the mount insulators for movement; if any is noted, lower the engine and tighten the mount fasteners. Applying rubber preservative to the insulators can help slow deterioration.

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage or wear on the drive line components.
