Engine Mounts do not wear out very often but if ever there is a broken/damaged one, then the mount must be replaced as soon as possible to avoid having to replace any part of the engine-drivetrain again. To do the check, securely place jackstands under the vehicle to take its weight off and position a jack under the engine oil pan with a large wood block between the two, then slowly raise the engine just enough to take all the weight off the mounts. Check the mounts, because they may be cracked, looking like hardened rubber, or have the metal casing in which they are located pull away from the other casing. Insert a large screwdriver or pry bar between the inner and outer portions of the mount, and listen or look for any relative movement; if there is any sort of movement, do not proceed further and replace the mount. Check that the mount fasteners are tightened and apply rubber preservative to reduce the rate of wearing. For replacement, it is necessary to disconnect the cable from the negative terminal of the battery, lift the vehicle on jack stands and get it up high on stands and put a supporting bar beneath the engine for additional space. To remove the right engine mount, undo the three bolts holding it to the body and the three bolts/nuts holding the mount bracket to the engine bracket; if your vehicle comes with A/C, there will be a refrigerant line bracket that joins the assembly. On the left engine mount, first you have to remove four bolts that fasten the engine mount to the body and the through-bolt to the transaxle bracket while prior procedures for the manual transaxle may be required. For the front and rear engine mounts, first, unscrew the bolts holding the engine mounts to the lower frame crossmember and the through-bolt to the engine bracket. In installation, one follows a process that is the opposite of the removal of the two pieces, and, for the mount bolts and nuts, thread locking compound is applied as the two are tightened.
