Engine and Gearbox Mounting

Engine and Gearbox Mounting

An engine mount is the part that holds the engine in your car. In most cars, an 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 the 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. The most common problem with the engine mount is when the rubber part breaks or separates or when liquid starts leaking out of the liquid-filled mount. Common symptoms of a failed engine mount is the increase in engine noise and vibration felt inside the car.

Maintenance

The most common problem with the engine mount is when the rubber part breaks or separates or when liquid starts leaking out of the liquid-filled mount. Common symptoms of a failed engine mount are:

• The increase in engine noise and vibration felt inside the car. Often, the excessive vibration is more noticeable at idle with the transmission engaged.
• In some cars, a broken engine mount can also cause a noticeable jolt or thump when shifting into Drive or Reverse or when accelerating or decelerating.
• A bad transmission mount may also cause squeaking when shifting gears.
• Visible signs of a failed engine mount include cracks, tears and separation in the rubber, as well as leaking liquid
• A worn-out engine mount may appear sagging. When one of the mounts is bad, an engine may appear seating lower on the side of the bad mount. Often when one engine mount goes bad, it adds more strain on all other mounts. For this reason, it's not uncommon to see two mounts that need replacement at the same time.

We would recommend leaving this job for your mechanic. This is because to replace an engine mount, the engine needs to be supported from underneath. It's easier to do this job in the shop on the lift.
