Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage or wear to driveline components. To check the mounts, raise the vehicle securely on jackstands and position a jack under the engine
Oil Pan with a large wood block in between. Carefully raise the engine just enough to relieve the weight from the mounts, then inspect them for cracks, hardened rubber, or separation from the metal plates, applying rubber preservative to slow deterioration. Check for any 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. For replacement, disconnect the cable from the negative battery terminal and detach the air cleaner duct. Support the engine from above with an engine support fixture or overhead crane, taking a slight amount of weight off the engine. Remove the engine mount throughbolts and raise the engine high enough to clear the brackets without forcing it too high. Unbolt the mount from the engine block and remove it from the vehicle, replacing self-locking nuts and bolts with new ones whenever disassembled. Before assembly, clean the engine block holes of any hardened residual adhesive. Attach the new mount to the engine block, install the bolts and stud/nuts securely, lower the engine into place, and install the through bolts, tightening them to specifications. Finally, reinstall all parts that were removed to access the mounts.
