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 mounts. 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, raising the engine just enough to relieve the weight on the mounts without fully supporting the engine. Inspect the mounts for any cracks, hardened rubber, or separation from the metal plates, noting that rubber may split down the center. Applying rubber preservative or WD-40 can help slow deterioration. Check for any relative movement between the mount plates and the engine or frame using a large screwdriver or prybar; if movement is detected, first check the tightness of the mount fasteners before concluding that the mounts are faulty, as broken mounts typically allow noticeable engine movement when pried or under load. For replacement, raise the vehicle and support it securely on jackstands, disconnect the cable from the negative battery terminal, and remove the under-vehicle splash shield. Position a jack under the engine oil pan with a wood block, ensuring it is not under the oil pan drain plug, then remove the engine mount-to-subframe nut and the engine mount-to-engine bracket nut. Raise the engine slightly to remove the engine mount, noting that on some models, it may be necessary to support the subframe and loosen the subframe bolts to provide enough clearance for removal. Installation follows the reverse order of removal, using non-hardening thread locking compound on the mount bolts and tightening them to the specified torque.
