Toyota brings Japanese efficiency and futuristic innovations to the USA with their range of stylish cars that are perfect for work and play. Many drivers always give care and maintenance to the obvious parts of their vehicle, such as the wheels, the engine, or the body work. However, few remember to care for some of the less glamorous parts, such as the motor mount. This actually has an integral role to play in your vehicle and should be properly maintained with the other components of your Toyota. With this in mind, in this article we’ll be looking at some of the signs and symptoms that your Toyota’s motor mount might be in need of replacement.
The motor mount is what supports your engine and your transmission inside your car. This is done to stabilize and secure the expensive parts, reducing the noise and vibrations they produce in this process. This creates a smoother and more enjoyable driving experience. Your motor mount is a simple part made of metal plates and rubber insulator blocks.
There are several different types of motor mounts that have been developed over the years, such as hydro-mounts. Also referred to as hydraulic mounts, the rubber blocks in this system are filled with fluid. This fluid absorbs chassis vibrations. This type of mount is common in four-cylinder and V6 engines. There are 3 main types of motor mount which your Toyota might have:
The most basic type of mount, passive rubber mounts are made of metal and rubber and are bolted to the body of the car as well as the engine. Rubber mounts are designed for longevity and will typically last the lifespan of your Toyota.
A little more advanced, as previously mentioned, the hydraulic or hydro-mounts are filled with glycol or hydraulic fluid which are able to dampen stronger vibrations. This kind of mount is more costly and is often found in luxury sports cars. This type of mount may not last for your Toyota’s total life span.
The most expensive type of mount, active hydraulic mounts, are usually reserved for high-end sports cars. The mounts in this system have a vacuum chamber which can adjust it’s stiffness to suit the situation.
As previously mentioned, aside from supporting your engine, the chief role of your motor mount is to keep noises and vibrations down to a minimum. Therefore, if you notice loud noises such as rattling or juddering noises coming from under your hood, then it is likely there is some fault with the motor mount, usually the rubber mounts.
As we learned along side reducing noise, the motor mount also dampens vibrations. Of course, any engine will hum with a gentle vibration when running and a little more when accelerating, but anything that could be deemed as more than a purr should be investigated. Excessive vibrations can destabilise your engine, which can result in damage.
Where the previous issues tend to highlight an issue with the rubber mounts, engine drooping can be a sign of the failure of the mount as a whole. The mount is designed to keep your engine central and level. If the mount warps or fails, then the engine may dip to one side or sit at a camber. This minor change can cause serious engine issues, so needs to be fixed quickly.
If your mount was installed incorrectly in the first place, then it will be unable to properly support your engine. This will likely cause damage and excessive loud noises and vibrations.
Parts naturally wear over time, and with wear, sometimes defects that were impossible to spot at manufacture can surface.
If your vehicle an older model or a classic, then your motor mount might simply reach the end of its left expectancy. Most commonly, this is due to the rubber mounts becoming dry and brittle, developing cracks and reducing their effectiveness in keeping vibrations and noise down.
