The two engine mounts are located on the passenger and driver's side of the vehicle attached to the engine block and to each frame rail. The transmission mount is mounted to the rear of the transmission and the transmission crossmember. During the check, the engine must be raised slightly to remove the weight from the mounts. To check the mounts, raise the vehicle and support it securely on jackstands. Support the engine/transmission from above using a hoist or three bar support fixture. Check the mounts for cracked, hardened, or separated rubber. Also, check for relative movement between the mounts and the engine or frame. If movement is noted, lower the engine and tighten the mount fasteners. To slow deterioration, apply rubber preservative to the mounts. For replacement, start by disconnecting the cable from the negative terminal of the battery and setting the parking brake. Then, raise the front of the vehicle and support it securely on jackstands. Remove the splash shields from under the vehicle. Remove the engine mount-to-frame nuts, two on each side. In the engine compartment, remove the engine mount-to-engine mount bracket nut(s), one on each side. Attach an engine hoist to the top of the engine for lifting, making sure not to use a jack under the oil pan. Raise the engine slightly until the engine mount can be removed. To remove the engine mount brackets, detach the four retaining bolts securing the mount bracket to each side of the engine. Installation is the reverse of removal, applying thread locking compound to the mount nuts before tightening them to the specific torque.
