Engine Mount Replacement
What is an engine mount?
The engine is held in place by mounts in the engine bay. They are designed to locate the engine in the chassis and prevent it from moving. They also absorb engine vibration for a smooth, quiet drive.
How does the engine mount work?
There are typically two or more engine mounts in a vehicle. Depending on the vehicle configuration, the engine will either rest on mounts bolted to the vehicle subframe, or will be suspended by mounts bolted to the vehicle's actual frame. In the case of front wheel drive vehicles, these mounts may also support the transmission from the side, and with stabilizers from above. There are several styles of mounts, ranging from solid rubber, to liquid filled.
Most modern motor mounts use a liquid filled core, which is contained inside of a composite rubber insert. This allows the mount to flex as needed while still preventing the vehicle from absorbing the vibrations and noise from the engine. This composite rubber insert, also called the insulator, is encased in a metallic housing to provide a firm, stable mounting surface for the engine and transmission, and the portion that connects to the engine is inserted into the insulator and secured via bolts. This design suspends the engine by composite rubber instead of metal.
