Car Engine Mounts

Connecting the engine to the chassis is the engine mount. Most mounts are constructed from rubber and steel, but rubber is more vulnerable to heat, chemicals, and external contaminants. Over time, the rubber material degrades, and you will feel vibrations and hear noises coming from the connection points. Without this part, power from the engine won't be transferred smoothly to the ground without rattling the chassis to pieces.

Engine mounts keep the engine in place at all times. Even if you try to mash your foot on the gas pedal to accelerate quickly, the engine won't twist itself from its place. One end of the mount is connected to the engine itself, while the other end is bolted securely to the vehicle frame. More than just securing the engine in place, the mounts fulfill another important role-isolating the surrounding steel from the harsh vibration as the engine produces power. Except for a few fancy types that employ viscous fluid or hydraulics, common mounts accomplish the job with rubber insulation in between two bonded metal parts. The rubber makes sure that the two metal mounting points are always together, while allowing minimal movement to absorb engine vibration.

Just like any rubber part, the car engine mount will eventually degrade and fail over time. It can become spongy, crack, or just disintegrate. If any type of liquid, whether it's oil, engine coolant, or transmission fluid, finds its way to the mount, this will hasten the deterioration process. Another way to accelerate the mount failure is when you have a high-performance engine. With increased power and torque, the mount's original design specs will be overwhelmed. Given enough time, torque-induced mount failure will be the result.

Because the car engine mount is one of the most overlooked parts in your vehicle, be extra vigilant when it comes to checking this component. If you notice an increase in metal noise and shaking under the hood, it's probably time to check and replace the mounts. For smaller engines, you can give a good two-handed push to check for excess movement. If there's one mount that has failed, it's best to replace all of them just to be sure. Some car manufacturers have solid mounts that are an alternative to its rubber cousins. While there's going to be a slight increase in vibration felt in the vehicle's interior, solid mounts are more durable.
