What is a motor mount?
An engine mount is the part that holds the engine in your car. In most cars, an engine and transmission are bolted together and held in place by three or four mounts. The mount that holds the transmission is called the transmission mount, others are referred to as engine mounts.
Engine mounts are made with a rubber material so that there is no direct metal-to-metal contact between the engine and the car body.
To further dampen the vibration, some engine mounts are filled with liquid. A liquid-filled engine mount works like a shock absorber.
How a failed engine mount is diagnosed?
Visible signs of a failed engine mount include cracks, tears and separation in the rubber, as well as leaking liquid. A worn-out engine mount may appear sagging.Before a bad engine mount is confirmed, all other causes must be eliminated. For example, when one of the exhaust pipe hangers is broken, it may create the same symptoms as a bad engine mount.When a bent or damaged exhaust pipe touches one of the chassis components, it also creates vibration and rattling noise when shifted to Drive or Reverse noticeable inside the car.Often, when one of the mounts is bad, an engine may appear seating lower on the side of the bad mount.Often when one engine mount goes bad, it adds more strain on all other mounts. For this reason, it's not uncommon to see two mounts that need replacement at the same time.

How to Replace Motor Mounts?
Part1 Removing the Engine Mounts
1 Choose a level, concrete surface (strong 3/4 inch plywood can make softer surfaces or the ground workable). Set the parking gear and the brake. Block the wheels. Raise the front of the Intrepid with a jack(s) and support the car with jack stands. Remove the splash guards under each fender to reveal access to the mounts.
2 Place a full width piece of 2 by 6, or 2x8 inch wood between a jack and the engine oil pan -- but not extending under the subframe. Raise the jack only until it just begins raising the engine a very little, to mainly support the engine, but not to raise the vehicle at all.
3 Loosen, but do not remove the upper nuts that connect the mount to the upper mounting-bracket using a ratchet and socket. (If your mounts have a heat shield between the mount and engine, remove the nut or bolt from the bracket holding the heatshield, using your ratchet and socket. Remove the heatshield.) Keeping the nuts loosely screwed on to just a few bolt threads, on the bolts, keeps the mounts aligned until both are loosened -- retained to this same degree, held on loosely, on each side of the engine.
4 Loosen the lower nuts: But, do not remove them from the bolt attaching them to subframe, through holes in the subframe, using your ratchet, an extension and a socket, for both mounts.
5 The transmission mount: Prepare to remove the third mount much in the same manner as the engine mounts (of a different design) at the rear of the transmission This mount may need to be replaced for backward and forward stability.
Part2 Installing Engine Mounts
1 Remove the mount nuts and replace only one mount at a time: Raising the engine far enough with the jack to get either one of the mounts off, then replace it as follows.
2 Slide the studs on the bottom of the new mount into the holes in the subframe -- and lower the jack a little to seat the engine mounting bracket down lightly onto the stud(s) on the top of the mount, maintaining alignment, so not binding, by tightening nuts and bolts little by little.
3 Install the lower nuts and "finger tighten" at the subframe, loosely as before, just by a few threads, to retain the engine positioning.
4 Install the upper nuts and "finger tighten", at the engine bracket, as well.
- Install the heatshield and its retaining bolts, if your vehicle is so equipped (on the 3.5-liter engine, for example).
5 Install the transmission mount by much the same techniques as the engine mounts.
6 Now, lower the engine a little. Snug the nuts and bolts on all both mounts, at first only "finger tight". Then snug them all a little.
7 Finally, torque all the mount attaching nuts and bolts to the manufacturers recommended number of foot-pounds with a torque wrench and a socket. The large nuts and bolts might be torqued to about 45 to 50 foot (13.7 to 15.2 m) pounds. The smaller bolts on the transmission mount are torqued less, perhaps to about 20 to 30 foot (6.1 to 9.1 m) pounds.
8 Remove the jack from under the oil pan. Raise the front of the vehicle enough to remove your jack stands or blocks and such, and lower the Intrepid to the ground.
Frequently Asked Questions:
1 ) Can you drive with bad motor mounts?
To put it bluntly, it's very unsafe to drive with a broken or weak engine mount. In the auto repair industry, we call them “impact noises” and they are often associated with an engine that is shifting around under the hood because of a damaged mount.
2 ) Can bad motor mounts cause jerking?
Car's 'clunking' and 'jerking' are classic signs of bad motor mount
3 ）Can bad engine mounts affect the transmission?
However, bad motor mounts will eventually create a host of problems with your engine, chassis, transmission and drivetrain, owing to excess engine/transmission movement and -- over a long enough period of time -- excessive vibration.
4 ) Should I replace all motor mounts?
Having a new motor-mount will transfer the excess torque to the old one, and it will break. Usually sooner rather than later. Best to do them both, or even all (including top, sides, and transmission, depending on yout configuation) while you have your tools and jack out.
5 ) How long do engine mounts last?How often should engine mounts be replaced?
Typically, they should last between 5-7 years, however, it is a good thing to have them checked regularly during every service, including routine oil changes.In general, motor mounts do not have a scheduled replacement but should last between 5 to 10 years before dry rot or breaking from age-related failure. Motor mounts can get broken from slamming the vehicle, gears over-revving, and letting out clutch or power braking the engine before takeoff.
6 ）How much does it cost to replace a motor mount?
The average replacement cost for an engine mount is anywhere from $220 to $570. The cost of the parts and labor can vary, depending on the make and model of your vehicle. The parts cost will likely be between $40 and $150, while the labor costs will be between $90 and $400
