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, and the negative battery cable should be disconnected. The vehicle should be raised and securely supported on jackstands, with a jack positioned under the engine oil pan, using a large block of wood between the jack head and the oil pan to carefully raise the engine just enough to relieve the weight on the mounts. The mounts should be inspected for cracked, hardened, or separated rubber, which may sometimes split down the center, and rubber preservative can be applied to slow deterioration. Relative movement between the mount plates and the engine or frame should be checked using a large screwdriver or prybar; if movement is noted, the engine should be lowered and the mount fasteners tightened. For replacement on non-supercharged models, the fan shroud mounting screws should be removed, and the shroud disengaged from the lower clips, followed by detaching the air cleaner duct. The engine mount through bolts and retaining strap bolt should be removed, and the shift linkage disconnected. Accessories and oil cooler line retaining clips must be removed from the engine mount brackets, and the engine should be raised high enough to clear the brackets without forcing it too high. A block of wood can be temporarily placed between the oil pan and subframe for safety. The mounting bracket should be unbolted from the engine block and removed, with self-locking nuts and bolts replaced with new ones whenever disassembled. Hardened residual adhesive should be removed from the engine block holes with an appropriate size bottoming tap. If a new mount is being installed, the nut and bracket should be removed from the old mount and transferred to the new one, along with the two bolts from the underside. The new mount should be attached to the engine block, with bolts and studs installed in the appropriate locations and tightened securely. The engine should then be lowered into place, and the through bolts installed and tightened. Finally, all parts removed to gain access to the mounts should be reinstalled to complete the installation.
