Engine mounts – check and replacement
1. The engine mounting system on these models consists of three molded mounts. The front (right and left) mounts support the engine assembly while the rear mount support the transmission and restricts torqueing action of the powertrain.
2. Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately, or the added strain placed on driveline components may cause damage or accelerated wear.
Check
3. During the check, the engine must be raised slightly to remove the weight from the mounts.
4. 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 to prevent oil pan damage, then carefully raise the engine just enough to take the weight off the mounts.
Warning: DO NOT place any part of your body under the engine when it’s supported only by a jack!
5. Check the mounts to see if the rubber is cracked, hardened or separated from the metal backing. Sometimes the rubber will split right down the center.
6. Check for relative movement between the mount plates and the engine or frame (use a large screwdriver or pry bar to attempt to move the mounts). If movement is noted, lower the engine and tighten the mount fasteners.
7. Rubber preservative may be applied to the mounts to slow deterioration.
Replacement Front mounts
This procedure is essentially the same as for the 3.7L V6 and the 4.&L V8 engines. Refer to Chapter 3.7L V6 and 4.7L V8 engines and follow the procedure outlined there but refer to the Specifications listed in this Chapter for the proper torque.
Rear mounts
Refer to Chapter Automatic transmission and follow the procedures outlined there, including torque specifications.
