Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to avoid damage or wear on driveline components. During the check, the engine must be raised slightly to remove the weight from the mounts. Begin by raising the vehicle and securely supporting it on jackstands, then position a jack under the engine oil pan with a large wood block in between to prevent damage. Carefully raise the engine just enough to relieve the weight from the mounts. Inspect the mount 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 chassis by using a large screwdriver or prybar. If movement is detected, lower the engine and tighten the mount fasteners. To replace the mount, disconnect the cable from the negative terminal of the battery, remove the engine splash shield fasteners and shield, and take out the coolant expansion tank. Place a floor jack under the engine with a wood block, then raise the engine slightly to relieve the weight from the mount. Remove the power steering fluid reservoir nuts and set the reservoir aside, disengage the wiring harness retainer from the valve cover stud, and move the harness out of the way. Detach the mount from the frame and engine by removing the fasteners, ensuring not to disconnect more than one mount at a time unless the engine is being removed. Installation follows the reverse order of removal, using thread-locking compound on the mount bolts and tightening them to the specified torque.
