The engine mount is a crucial component of your vehicle as it is responsible for securing the engine and absorbing any shocks and vibrations when the machinery is in operation.

Anti-vibration mounts and engine mounts play a vital role in preventing engine damage and promoting complete control. It is crucial to replace the engine mount when it shows various symptoms of malfunctioning.

You should immediately replace the engine mount if you notice any negative impacts or changes in its performance. This will prevent severe problems in other parts of your car.

1. Vibrations

Increased vibrations are a common symptom of a worn engine mount when using your vehicle. If you notice your engine making more noise and feeling more vibrations than usual, this is a sign that your engine mount needs immediate replacement.

A damaged engine mount loses its anti-vibration properties, resulting in increased vibrations and engine noise. If left unchecked, these vibrations can cause severe damage to the engine, leading to higher repair costs. Replacing the engine mount as soon as possible is essential to avoid further damage and expenses.

2. Visual Wear

When an engine mount’s metal parts start showing signs of corrosion, cracks, or warps, it indicates excessive wear to the entire mount.

Similarly, any cracks or flaking on the rubber aspect of an engine mount can limit its performance, depending on the severity and cause of the cracks. In some cases, repairs may not be possible, and you may need to replace the engine mount promptly to ensure optimal performance.

3. Bumpier Ride

If you experience a jolt or thump when changing gears on an attached transmission, it may be a sign that you need to replace your engine mount. This is especially noticeable when traveling faster, as the engine works harder.

If your engine is not functioning as smoothly as it used to, it could be due to a damaged engine mount. Therefore, replacing it as soon as possible is essential to avoid further damage to your vehicle’s transmission and engine.

4. Impact Noises

If you notice unusual sounds coming from your engine bay, it could be due to a bad engine mount. A worn engine mount is often the cause of “clunks” and “bangs” within the surrounding area.

These noises occur when the engine moves around more than usual and interacts with other components, resulting in noticeable impact sounds. Therefore, if you hear such sounds, it is essential to inspect your engine mount for any damage and replace it if necessary.

5. Rocky Start

One of the signs of worn engine mounts is a rough start, which can be felt or heard as a shock or sudden movement when the engine is turned on. This can lead to continuous vibrations and a jolt when turning the engine off.

Engine Mount Replacement Cost

Knowing the engine mount replacement cost is crucial to plan ahead and avoid overpaying when consulting a mechanic.

Currently, the cost of a new engine mount part ranges from $75 to $350, with labor costs depending on the job’s complexity and the vehicle’s make and model. For instance, replacing the top engine mount in a Mazda 3 or Mazda 5 costs between $150 and $215, while replacing two broken mounts in a Honda Odyssey can cost up to $1,800 for parts and labour.

The price difference between different vehicle parts depends on their availability and quality. It is essential to conduct thorough research before buying aftermarket parts and ensure their quality. For example, a search on Amazon for engine mounts for the 06-11 Honda Civic revealed several brands with ratings ranging from 3 to 4.5 stars. Investing in a high-quality engine mount is advisable to ensure it performs well for a long time.

In some cars, the Powertrain warranty may cover the engine mount, typically valid for five years or 60,000 miles. Verifying your car’s warranty booklet is essential to determine if the engine mount replacement is covered.

Causes of Worn Engine Mounts

1. Driving techniques that can damage the vehicle’s parts

Improper use of the clutch and over-revving the gears can significantly increase the risk of causing damage to your engine mounts.

2. Aging and weathering over time

Engine mount failure is frequently caused by aging and wear. Nowadays, engine mounts are commonly made of rubber, susceptible to wear and tear over time. The rubber material may lose its elasticity, which can reduce its function and effectiveness for your engine.

3. Accident involvement which has caused damage or moved the mounts

After an accident, it’s important to thoroughly inspect your vehicle for internal and external damage, including engine mount failure and superficial damage.

4. Incorrect installation of the mounts

Although rare, a bad engine mount can occur due to various reasons.

Is it easy to replace an engine mount as a DIY project?

We strongly advise against replacing your vehicle’s engine mount on your own, as attempting to do so may result in further damage to your vehicle’s engine or other parts.

It is best to leave the job to a professional mechanic with the necessary mechanical experience and tools. Replacing an engine mount requires supporting the engine from underneath, which can be challenging without proper equipment. It is also easier to perform this task in a shop with a lift.
