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.
