How to Replace a Motor Mount in Cars

by Contributing Writer; Updated June 12, 2017

In a way, it's not really fair to call the later-model Chrysler car a "minivan. " The minivan as a concept was an evolution of the station wagon -- a taller evolution, but still a sedan underneath. But the Chrysler car CS platform is a fully bespoke unit, used only by the Chrysler car and designed specifically for it. So, the only thing that this whatever-it-is shares in common with its lesser minivan cousins is its basic shape, engine, transmission, windows wheels, headlights, seats, dashboard, bumpers, two lower and one upper motor mount and -- oh, nevermind. It's a minivan.

 How to Replace the Motor Mounts on an Altima

Support the engine with a floor jack. Place a piece of wood underneath the oil pan and jack up on the piece of wood. Alternatively, you can place the wood on the jack and try to center the wood on the oil pan. You need a piece of wood that is flat (like press wood) but also strong and wide to distribute the force of the jack across the oil pan. This will prevent the jack from crumpling the oil pan by accident. You need only support the engine. Do not try to lift up on the engine; otherwise you will damage the oil pan and the oil pickup inside the pan.

Use the socket wrench to remove one of the bolts that connects one of the motor mounts to the bracket on the engine. It does not matter which mount you start with; just remember that you should only work on one motor mount at a time.

Remove the bolt that secures the mount you are working on to the frame of the vehicle.

Slide the mount out of the engine's mounting bracket and remove the mount.

Install the new mount. Installation is the reverse of removal.

Torque the motor mount bolt to the torque specifications listed in your Altima service manual for your specific year of Altima. Different model years and engine sizes used in the Altima have different torque specifications.

Repeat Steps 2 through 6 for all the motor mounts.

Items you will need

  • Floor jack

 How to Replace the Motor Mounts in a Contour

Drive the front tires of the Contour onto the ramps. Set the parking brake and place the wheel chocks behind the rear wheels.

Raise the hood and locate the top engine mount, which runs from the top-front of the engine out to the strut tower. The mount is popularly referred to as a "dog bone," due to its resemblance to a dog’s bone, which makes its visual identification quick and easy.

Unbolt the mount from the strut tower bracket by placing one socket and wrench on the bottom nut to hold it steady while you loosen the bolt from the top with the other socket and wrench. Be careful not to let the nut fall into the engine well.

Unbolt the mount from the engine in the same manner, using both socket and wrench combinations to remove the bolt and nut. Pull the mount out by hand.

Bolt the new mount to the engine in reverse of the removal procedure. Align the other end of the mount with the strut tower bracket and bolt that side down in the same manner. You may need to move the engine a bit to line them up, using the pry bar. Be careful not to pry on anything that can break--such as exhaust shields, engine accessories or plug wires.

 How to Replace the Motor Mounts on a 2004 Chrysler Pacifica

Lower Mounts

Lit the front of the van enough so that you can crawl underneath, and support it with jackstands. Disconnect the negative battery cable, and remove the bolts securing the engine cover to the engine. If removing the left-hand mount, you may need to unplug and unbolt the cooling fan assembly from the radiator.

Install the engine support fixture. The engine support bar specified by Chrysler for this job is a three-bar unit. It's shaped like a capitol "T." On the tips of the horizontal "T" bar are "feet" that sit on the fenders on either side of then engine bay; the bottom tip of the bar has a foot that sits on the radiator support. hooks hanging down from the bar engage the factory lift hooks on the motor. When you install the bar, you'll turn the jack-screws on the chain to lift the engine and support its weight with the bar instead of the mounts.

Remove both of the engine mount-to-chassis nut, then lower the vehicle to gain better access to the mount bolts. Remove them, and turn the jack-screws to lift the engine slightly to relieve stress on the mount; pull the mount out. Install the new mount as you took the old one out, and lift the van again. Tighten mount-to-bracket nut to 75 foot-pounds, tighten the engine block bolts to 40 foot-pounds. Remove the engine support bar, reinstall the remaining fasteners and tighten them to 75 foot-pounds. Reinstall the fan and tighten the screws, if you pulled it off.

Top Mount

Support the bottom of the engine with a floor jack and block of wood so it won't tilt, and remove the air cleaner filter housing. You don't need to use the engine fixture for this one, since the upper mount's job is only to keep the engine from rotating. With the engine not running, it doesn't bear much actual load.

Remove all of the bolts from the upper mount. You'll find three bolts securing the mount to the intake manifold, and two securing it to the frame.

Drop the new mount in place of the old. Tighten the intake manifold bolts to 40 foot-pounds, and the frame bolts to 50 foot-pounds.

Items you will need

  • Floor jack

  • Jack stands

  • Chrysler Three-Bar engine Support Fixture

  • Socket and Wrench Set

  • Screwdrivers

  • Penetrating oil

  • Torque wrench

 How to Replace Motor Mounts On a Mercedes Benz

Pop the hood of your Mercedes Benz to inspect the motor mounts. Common causes of malfunction include loose or fractured mounts. Reference the service manual for your model of Mercedes Benz for more specific instructions on locating the motor mounts. If the mounts are simply loose, you may only need to tighten them.

Set up a hydraulic jack underneath the engine of your car. Lift the engine of your Mercedes Benz with the jack until the stress has been removed from the motor mounts.

Check the flexible joint on your Mercedes Benz motor mounts for operational quality. Joints on motor mounts may become inflexible over time, reducing the mounts' ability to secure the engine without transferring physical shock while the vehicle is in motion. With the pressure relieved from the mounts, you can check the flexibility of each motor mount's rubber-coated joint with a screwdriver. Use your screwdriver to poke the rubber coating on the motor mount and note if the coating has any give to it. If the rubber is inflexible, the mount must be replaced.

Remove the motor mounts from your Mercedes Benz. Use a socket wrench and an appropriately-sized bit to remove the bolt securing the mounts to both the engine and other fixtures in the car hood. Some mounts can be removed through the top of the hood while others may need to be removed from underneath due to fixtures blocking the mounts from above.

Install your replacement motor mounts into the car hood of your Mercedes Benz. Mounting bolts will be included in the replacement motor mount packaging. Secure the motor mounts by tightening bolts in the appropriate locations with your socket wrench and wrench bit.

Release the hydraulic jack slowly to lower the engine of your Mercedes Benz. Close the car hood.

Items you will need

  • Hydraulic jack

  • Mercedes Benz service manual (if necessary)

  • Screwdriver

  • Socket wrench and wrench bits
