Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent 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 remove the splash shields. Position a jack under the engine oil pan with a large wood block between the jack head and the oil pan, carefully raising the engine just enough to relieve the weight on the mounts, avoiding placement of the wood block under the oil pan drain plug. Inspect the mounts for any cracks, 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 prybar; if movement is detected, lower the engine and tighten the mount fasteners. Applying rubber preservative can help slow deterioration. For replacement, disconnect the cable from the negative terminal of the battery, raise the vehicle, and support it securely on jackstands while supporting the engine. To remove the upper torque rod, take out the through-bolts and bracket bolts. For the front engine mount, place a floor jack with a block of wood under the oil pan, then remove the torque rod bracket, engine mount to body bolts, and engine mount-to-engine bolts before taking out the mount. To remove the lower torque rod, again remove the through-bolts and bracket bolts. For the left-hand mount, remove the battery and battery tray along with the air filter housing, then support the transaxle with a floor jack. Remove the mount top bolts and side bolts through the wheel well, then take out the mount. Installation follows the reverse order of removal, ensuring to use thread-locking compound on the mount bolts and nuts, tightening them securely.
