Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent added strain on driveline components that may cause damage or wear. During the check, the engine must be raised slightly to remove the weight from the mounts. Raise the vehicle and support it securely on jackstands, then 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 take the weight off the mounts while avoiding the drain plug. Inspect the mounts for cracked, 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 pry bar; if movement is noted, lower the engine and tighten the mount fasteners. Applying rubber preservative can help slow deterioration. To replace the mounts, disconnect the negative battery cable, raise the vehicle, and support it securely on jackstands while supporting the engine as previously described. Caution is advised if the vehicle's stereo has an anti-theft system, ensuring the correct activation code is available before disconnecting the battery. For the right engine mount, remove the nuts from underneath, one bolt from above, and separate the upper section from the engine bracket, then detach the mount after removing the mount-to-chassis nuts. For the left engine mount, remove the mounting bolt and nut, separating the upper and lower mount, and then remove the bolts from the engine block and chassis retaining the insulator. Installation follows the reverse order of removal, using thread locking compound on the mount bolts and nuts, ensuring they are tightened securely.
