What is a Front Engine Mount and Why is it Important For Your Honda?
If you look around your engine compartment, you’ll find four rubber mounts than attach the engine to the chassis. They keep your engine in place, and provide several other important benefits.
How Front Engine Mounts Drastically Improve Your Honda’s Ride Quality
When you drive your car, you make a lot of turns and stops. Inertia comes into play a lot (which is why your body involuntarily lurches forward when the car stops or leans to the side when the car makes a turn). Since the engine is so large and heavy, it’s not immune to inertia. That’s why engine mounts exist.
The car chassis and engine both have brackets designed to hold engine mounts. The engine mounts are then sandwiched between the engine and chassis mounts when the car is assembled. Most engine mounts are made from a soft piece of rubber mated to a steel plate. The rubber absorbs vibration. Some mounts use hydraulic fluid to absorb vibration.
With a good set of OEM engine mounts on your car, your Honda’s ride quality is pretty spectacular. More specifically, engine mounts:
- Reduce noise and vibration
- Provide smoother drivetrain "feel"
- Reduce wheel hop on hard acceleration
What Happens When One of Your Front Engine Mounts Fails
While engine mounts don’t require any regular maintenance, they will wear out over time. Since many Honda's run several hundred thousand miles or more, it's not uncommon for the engine mounts to wear out on these high mileage cars. Engine mounts start to sag when they wear out, and they lose strength. When one of your engine mounts fails you may run into some serious problems like:
- Excess noise and vibration: The mounts are supposed to absorb vibration. When a mount fails, more vibration is transmitted to the chassis. You'll feel this and hear it while your driving.
- Damaged components under the hood: The chassis isn’t the only thing your heavy engine could break while shifting around under the hood. If it moves enough, it can bump into other components and possibly damage them.
- Damaged radiator hoses: Radiator hoses are flexible, but they also are molded to a specific shape to fit between the engine and radiator. When an engine mount fails and sags, the radiators hoses get stretched out of shape. If this goes on long enough, they can tear and leak, causing your car to overheat.
So if you start to experience the symptoms of a bad engine mount, replace them as soon as possible. The good news is you can do it yourself at home.

This tutorial is based on 2006-2011 Honda Civics, but you should be able to follow the steps with any other Honda model.
The first thing you need to do is to buy OEM replacement motor mounts. We recommend replacing all four mounts at the same time to prevent further issues. You can find a set of genuine OEM motor mounts in our catalog, or you can check out this list of our top selling mounts:

When you have your replacement mounts, take the following steps to replace the old ones in your Honda:
- Support your engine by placing a floor jack and a piece of wood under your oil pan and applying light tension to it.
- Find the three bolts holding the upper torque rod in place. Unscrew all of them with a 17mm socket. Be careful not to break the A/C line.
- Gently pull out the upper torque rod.
- Remove the bolts underneath holding the brace between the engine and one of the engine mounts in place. Apply some rust penetrant if needed. The engine will drop a little bit. Make sure the floor jack is firmly holding the engine up.
- Locate the bolts on each side of the engine mount. Unscrew these bolts.
- Remove the engine mount. It should slide out of there, but you may need to wriggle it around a bit to get it out.
- Install the new engine mount in the reverse order.
- Repeat with the other engine mounts.
