Engine Mounts generally are trouble free, however if any of the Engine Mounts are broken or are worn out, they should be replaced at once so that they do not cause further damage to or wear out the other components of the driveline. To inspect the mounts, it is necessary to lift the car with jack stands and place a jack underneath the engine oil pan or better yet, place a large wooden block underneath the engine and jacking it up enough so that the block will be under the engine but not the drain plug. Looking at the mounts they should be thoroughly inspected for any cracks, hardening, or if they have come off the metal casing altogether, at which point they require replacement and depending on the engine model, look at the movement of the engine movement rod and feel for any play. Further, loosen the mount by applying force on the concentric portion with the help of large screwdriver or pry bar and check the relative movement between two portions of mount; if there will be movement then it should be replaced. Check that the mount fasteners are tight. For replacement, the cable must be disconnected from the negative terminal of the 12-volt battery and the initialization is done when reconnecting. Place an engine support fixture underneath the engine, followed by the removal of the right Engine Mount bolted to the body through three bolts and bolted to the engine bracket through three bolts and two hardened nuts, while removing it, the refrigerant line bracket needs to be detached from the mount. For the left Engine Mount, take out four bolts: the ones that holds the mount to the body, and the through-bolt to the transaxle bracket. Nullify the bolts that fasten the front and rear brackets to the lower frame crossmember, through-bolt to the engine bracket. On this note, installation is done in the reverse order of removal, and on the mount bolts and nuts, one applies a thread-locking compound before tightening them.
