There are three powertrain mounts, include left and right engine mounts joining the engine block to the subframe, as well as a rear mount which is joined to the transmission and the frame. In the process of check the engine must be lifted slightly off the mounts to take off the weight of the engine. Chock the wheels and raise the vehicle on jack-stands and place a jack beneath the oil pan with a sufficiently large chunk of wood between the jack head and the oil pan, thereafter, lift the engine barely off the mounts. Check the mount insulators for signs of cracking, any indications of hardening or the fact that they are no longer attached to the metal center. There should be no relative movement between the mount and the engine or subframe; try to move the mounts by inserting a large screwdriver or prybar in-between them. If movement is detected, lower the engine and also use the mount fasters to tighten it. To dismount the mounts, remove the cable from the negative terminal of the battery, if not already done, and raise the vehicle securely on jackstands, and place the jack on the lower section of the engine oil pan supported by a large wood block. If removing the right side engine mount, then the alternator support bracket will have to be taken out also. Subsequently, it is possible to take out the mount-to-subframe nuts and then lift the engine employing the jack while the mount-to-engine bracket bolts should be taken out as well. Lastly, fit the new mount as it is placed correctly into the bracket and tighten the screws nicely.
