An engine mount is the part that holds the engine in your car. In a typical car, the engine and transmission are bolted together and held in place by three or four mounts. The mount that holds the transmission is called the transmission mount, others are referred to as engine mounts.
One part of an engine mount is bolted to the car body or frame. Another part holds the engine. An engine is a source of vibration, as it has many moving and rotating parts. The job of an engine mount is not only to hold the engine in place, but to reduce the engine vibration felt inside the car.
Engine mounts are made with a rubber material so that there is no direct metal-to-metal contact between the engine and the car body. To further dampen the vibration, some engine mounts are filled with liquid. A liquid-filled engine mount works like a shock absorber.
How long can an engine mount last? In some cars, engine mounts can last the life of the vehicle. We see the most of the problems with engine mounts starting to show in 5-7 year-old vehicles. Transmission mounts last longer.
