A car's engine mounts do not really need regular servicing but there is need to replace or repair any broken or deteriorated ones as soon as possible so as not to affect other parts of the driveline. Normal check on the mounts also requires that the engine be lifted slightly off its full weight on the mounts. First of all, lift and safely support the car on jack stands; then place a jack beneath the oil pan under the engine; taking a piece of wood and place it between the head of the jack and the oil pan and slowly raise the engine up enough to relieve some pressure off the mounts. Thus, it is unnecessary to put any part of the body under the engine when it is only lifted with the help of a jack. Sometimes, if the jack and wood would allow the automobile to sit beneath, then lifting of the car may not be required. Look for areas that may have cracks or areas of rubber that have become hard, a fact one should bear in mind is that such splits may run down the middle of the mount. As an assistant should try to lift the jack to check whether the upper part of the mount separates from the lower part; if yes then the mount is to be replaced. Use a large screwdriver or pry bar to employ force and see if the mount plates are moving relatively to the engine or the frame. If you see movement go back down and snug up the mount bolts. To remove the mount, you pull the cable on the negative terminal of the battery, unclasp the air intake duct that is connected to the throttle body and if replacing the left side mount, the air filter housing should be removed for ease of access. Take off the throttle body and also the bolt wherein the accessory bracket is placed at the front of the left cylinder head. For the engine support fixture or hoist, there should be a chain provided and with that chain you should have used the removed bolt to fix it into place and make sure it is properly anchored and tight. Another method is to use a floor jack along with a piece of wood under the oil pan At the same time it is necessary to take care that the legs of the engine support fixture do not rest on the fenders-they should be placed on the nearest body part to the suspension strut tower . Screw the mount off the mount bracket and chassis, unscrew the mount bracket from the engine and finally screw the mount off. Disassembly starts from the outer end of the wire harness and installation also does the reverse starting with the mount fasteners which is then tightened to torque specified to lock into action a thread-locking compound.

To check the transmission mount, insert a large screwdriver or prybar into the space between the transmission and the crossmember and attempt to pry the transmission up; any separation of the rubber indicates that the mount is worn out. For replacement, first remove the transmission crossmember, then take off the nuts attaching the mount to the crossmember and remove the mount. Installation follows the reverse order of removal, ensuring that the nuts and bolts are tightened to the specified torque.

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage or wear on the drive line components.
