The cost of replacing an engine mount is between $30 and $60. Even though the engine mount is relatively inexpensive, it is an integral part of any vehicle. This mount secures the engine to the car's frame, supporting engine torque and excessive vibration. It is constructed of high-grade steel and an internal rubber fitting to absorb shock.

Replacing an engine mount will cost considerably more should you request the services of a professional mechanic. However, it's a repair that can be easily performed as long as you have the proper tools. Follow the steps outlined below.

Step 1 - Raise the Car

Make sure your vehicle is on flat terrain. Raise the front end of the car on its proper support columns using the floor jack. Use the jack stand to support the car, then move the floor jack so that it sits directly underneath the engine.  When a mount is removed, the engine drops, possibly damaging cables or other valuable components in the process. To avoid this situation, place a long block of wood on the jack running parallel to the car's axles to lend a higher degree of support. Raise the jack with the piece of wood until it is touching the underside of the engine.

Step 2 - Remove the Nuts

Engine mounts sit on both sides of the engine. Locate the one you intend to replace. Using your socket wrench and a large ratchet, loosen the nuts of the engine bracket holding the mount in place. Some brackets also have a grounding strap attached to one of the nuts. This must be removed as well.

Step 3 - Remove the Large Bolt

Locate the large bolt running through the center of the engine mount. Using the ratchet and an appropriate socket wrench, loosen the bolt. Listen for the nut on the opposite side of the mount to drop. Now remove the bolt and carefully pull the mount out of the vehicle. You may need to use a pry bar if it is stuck. 

Step 4 - Install the New Mount

Insert your new engine mount into the engine bracket slot, making sure that the fit is correct. Using your hands, screw the large bolt into the engine mount while holding the corresponding nut on the mount's opposite side. Use your socket wrench and ratchet to tighten the bolt as much as possible. Reattach the smaller nuts, as well as the grounding strap if applicable, using the socket wrench. Repeat the process for any other engine mounts requiring replacement.

Step 5 - Remove the Jack

Release the pressure of the floor jack. You should see the engine dip slightly then settle into place. If the engine continues to drop, re-insert the floor jack and the piece of wood to lift it. Examine the engine mount and make sure it's properly situated in the engine bracket. double-check the tightness of all bolts. When the repair is complete, remove the jack stand.  

The cost of replacing an engine mount may be minimal, but the importance of the mount itself can not be underestimated. By performing this repair, you not only save money, you prolong the life of your vehicle in the process.
