Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately or the added strain placed on the driveline components 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. Place a large wood block between the jack head and the oil pan, then carefully raise the engine just enough to take the weight off the mounts. Check the mounts to see if the rubber is cracked, hardened or separated from the metal plates. Sometimes the rubber will split right down the center. Check for relative movement between the mount plates and the engine or frame. If movement is noted, lower the engine and tighten the mount fasteners. Rubber preservative should be applied to the mounts to slow deterioration. To replace, disconnect the cable from the negative battery terminal. Raise the vehicle and support it securely on jackstands. Place a large wood block between the jack head and the oil pan, then carefully raise the engine just enough to take the weight off the mounts and through bolts. Remove the through bolts that connect the upper and lower motor mount halves. Once the bolts have been removed from the mounts on both sides of the engine, raise the engine up until the fan blades just meet the fan shroud. Place a wood block between the frame and the
Exhaust Manifold, on both sides of the engine. Remove the mount-to-block bolts and detach the mount. If the mounts are being replaced, the bolts attaching them to the frame can be reached with a socket and long extension through the access holes in the frame. Installation is the reverse of removal. Use thread locking compound on the mount bolts and tighten them to the torque.
