Toyota Sienna Motor Mounts

The Toyota Sienna minivan began production in 1997. Over three different generations, the Sienna model has encompassed many standard, luxury, and even all-wheel-drive models. If you need to replace or upgrade the motor mount in your Sienna, then this information about the parts can help.

What is a motor mount?

The motor mount, or the engine mount, as its also called, secures the engine and the transmission to the chassis of the vehicle. The main purpose of the motor mount is to insulate the engine from major shocks and vibrations as you are driving. The Toyota Sienna contains multiple mounts, including those to the left and right and to the front and back. The motor mount may need to be replaced during the life of the Sienna because it naturally wears out over time. However, the longevity of the mount will vary depending on the number of miles driven and the severity of the driving conditions.

The rubber or polyurethane section of the mount is particularly prone to deterioration because it absorbs and dampens all of the shocks. If the motor mount is cracked or damaged, the resulting shocks and vibrations can cause severe damage to the sensitive parts of the engine. You should replace it or fix it as soon as possible. Symptoms of a bad motor mount include oil leaks, loud noises, or the engine moving around in the engine compartment. Replacing the mount can be a labor-intensive process since it involves lifting heavy engine parts.

What factors should be considered in choosing the right mount?

One factor in picking a motor mount is what type of material it is made from. All motor mounts are made of solid metal, which provides stability under the enormous force of a moving vehicle. However, the metal part of the mount is usually covered with a solid rubber or polyurethane material to absorb additional shocks. Both materials have different strengths. Rubber is a good all-around absorbent material. Polyurethane gives your vehicle a slightly better response but at the cost of more noises and vibrations. Some specialized motor mounts are equipped with hydraulic fluid that dampens the vibrations more effectively. Hydraulic dampeners are sometimes found in high-end vehicles. An electronic hydraulic mount is even capable of dynamically changing its own shock absorbent capabilities based on the needs of the vehicle.

Do I need to consider compatibility of the replacement mount?

Yes, before purchasing any replacement parts, you need to make sure that the mount will fit with the model year and trim style of your Toyota Sienna. All individual parts and inserts also need to be checked for their compatibility. The Sienna needs to have specific parts that meet the original specifications of the manufacturer. If your Toyota Sienna needs to endure more turbulent driving conditions, however, then aftermarket parts are available that will improve the durability and dampening ability of the mount.
