How Do I Replace Motor Mounts for a Toyota Corolla?

by Cayden Conor

Most four-cylinder Toyota Corollas use three motor mounts. There is a mount for the front of the engine, near the fan belts; a "dog bone" mount on the side of the engine, which is mounted to the front support by the radiator; and a mount on the firewall side of the engine, which is usually called the left mount or transmission mount. You must support the engine to remove the front mount or the transmission mount. The rubber in the mounts wears after years of stress from the engine lifting back and forth during shifting and acceleration.


Place the block of wood on the floor jack. Roll the floor jack under the oil pan and jack it up enough so that it touches the bottom of the engine, to support the engine. Work on one mount at a time.


Remove the through-bolts from each engine mount by holding the head of the bolt with a wrench and removing the nut with the appropriate socket. Pull the through-bolt out of the mount. Unbolt the mount with the rubber insulator. The side with the rubber insulator is usually bolted to the engine, or transmission in the case of the left/rear mount.


Bolt the new mount to the engine, and tighten the bolts firmly. If the through-bolt does not slide through the mount bracket, use the floor jack to adjust the height of the engine until the bolt slides through. Reinstall the nut on the through-bolt and tighten firmly. Repeat Steps 2 and 3 for all three mounts.
