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, raising the engine just enough to relieve the weight from 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 any 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, some models feature active engine mounts that require disconnecting the vacuum line before removal. 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 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. For CVT models, support the transaxle with a floor jack and remove the insulator through bolts to take out the pull-down rod mount. To remove the rear torque rod, take out the through bolts and bracket bolts. For the left-hand mount, remove the air filter housing, support the transaxle with a floor jack, then remove the mount top bolts and side bolts through the wheel well before taking out the mount. Installation follows the reverse order of removal, using thread-locking compound on the mount bolts and nuts, tightening them to the specified torque.
