Let’s examine the factors that influence motor mount replacement costs.

Automobile repair costs typically consist of two elements: the price of the part and labor expenses. Both of these factors are subject to variation. The part’s cost depends on the specific motor mount type, while labor costs fluctuate based on your location.

Now, let’s explore the individual components of motor mount replacement costs. Steel or rubber mounts range from as low as $10 up to $150, while hydraulic and active motor mounts tend to be pricier, costing between $50 and $200.

The labor portion of the motor mount replacement cost relies on the specific engine mount being utilized. For example, a top engine motor mount requires around 30 minutes of labor, while one located deeper within the engine will be more costly. Labor costs generally fall within the $100 to $150 range.

Motor Mount Replacement Cost: How to Replace it?

If the cost to replace motor mounts seems steep to you, a steady hand towards mechanical work can save up a fortune. If you are handy with your engine, you can do the replacement yourself, which will save up a huge chunk of the engine mount replacement cost.

Here’s a simple step-by-step guide for motor mount replacement:

  • Begin by disconnecting the negative cable from your engine’s battery. This step helps prevent any electrical issues during the replacement process.
  • Ensure that your engine is well-supported, as removing the motor mount can put it in a vulnerable position. Utilize a set of jack stands to keep your vehicle stable while performing the replacement.
  • Next, remove the bolts connecting the engine mount to the engine and the chassis. At this point, you can replace the motor mount.
  • Swap the old mount with the new one and reinstall the bolts for a secure fit.
  • Keep in mind that, in some cases, you may need to remove additional engine components or parts of the subframe if the motor mount is located deeper within the vehicle’s structure.

Motor Mount Replacement Cost: Understanding the Component

Before we get into the particulars about the motor mount cost, symptoms, and replacements, it is only fair first to understand this component and its functions well. So, what is a motor mount?

A motor mount’s function in a vehicle is to stabilize the engine. It does this by ensuring that the internal combustion’s natural vibrations do not harm its surrounding parts. It is an extremely crucial part of your car as it is the component that holds the engine or the part on which the motor is ‘mounted.’ It is also called an engine mount.

Cost to Repair Motor Mounts: Types of Engine Mounts 

When a driver revs the car, it is bound to move a little. The engine mount ensures this movement causes minimal disruption and damage.

The type of engine mount will greatly determine your replacement cost and even the bad motor mount symptoms that your car could be exhibiting.

There are majorly five types of motor mounts. They are as follows:

  1. Solid Rubber Motor Mounts: These are one of the most commonly produced and used motor mounts today and utilize rubber and a steel backing plate to offer support. They are simple and ensure strength and durability. It should be noted that the rubber is bound to wear out, which will cause symptoms eventually.
  2. Metal Motor Mounts: This type of motor mount is known for its extreme durability and is known to falter rarely. One drawback to these mounts is that they transmit or pass through vibrations more than the other types.
  3. Polyurethane Motor Mounts: These are other durable mounts claimed to be stronger than rubber mounts. They are stiffer and less heat-resistant but more pliable than steel ones.
  4. Hydraulic Motor Mounts: These are unique motor mounts. It uses glycol or some other fluid or gel-like substance within the part. This is used to dampen down the engine’s vibrations. These highly advanced motor mounts can be tuned to need frequencies to reduce vibrations at will. They are expensive due to their advanced manufacturing and are prone to more breakage and varied motor mount symptoms.
  5. Electronic Engine Mounts: These use positioning sensors to monitor the engine’s position, RPMs, speed, etc., to reduce the force coming onto the mount, also referred to as active engine mounts.

Bad Motor Mount Symptoms

To understand your engine mount replacement cost, you need to understand the damage that is being caused, which is reflected by the motor mount symptoms exhibited by your car.

Sounds Coming From the Engine Bay

Sounds of repeated impacts are one of the most common motor mount symptoms. This noise will come from the engine bay and can feel like a banging, thumping, or clanking sound. Why so?

This indicates that the motor mount isn’t securing the engine properly, which is shifting from one side to the other, leading to it bumping into the cradle’s walls.

Stronger Vibrations

A mild vibration in a car’s engine is normal; however, if you notice an unusual or increased vibration level, your car might display one of the more severe motor mount symptoms.

This issue can arise when the motor mount begins to fail. Over time, the rubber, dampening fluid, or other materials, depending on the motor mount type, may wear down, causing instability in the engine support.

As a result, the motor mount becomes less effective at absorbing and mitigating engine vibrations. This can create the sensation that the entire car is shaking and vibrating.

A Tilted Engine

We’ve mentioned that a motor mount plays a crucial role in supporting the engine and ensuring its proper alignment.

For optimal performance, a motor must maintain even alignment without any discrepancies in height across its corresponding cross-section.

A misaligned motor can result in mechanical issues, such as a tilted or sagging engine, a symptom of a defective motor mount. Is this a severe symptom? Indeed, it can be. If left unaddressed, a misaligned engine may droop significantly to one side, leading to a complete system failure.

Engine Block Damage 

Let us now discuss one of the most extreme bad motor mount symptoms and repercussions. Bear in mind that this represents the most severe outcome. Ignoring significant motor mount symptoms, such as a misaligned engine or persistent impact noises, can lead to further complications.

The motor mount’s function is to support the engine; if it fails to perform effectively, the engine may ultimately disintegrate or start to move erratically, resulting in extensive damage as it collides with nearby surfaces.

If this occurs while the car is being driven, it can lead to fatal accidents, which make these symptoms unavoidable and urgent. 

Now that we have discussed motor mount symptoms is terrible news. Let us move on to the engine mount replacement cost.

FAQs 

Below are the frequently asked questions talking about motor mounts cost to help gain more clarity on the subject.

What happens when motor mounts go bad?

A failing motor mount can cause severe damage and negatively impact the vehicle’s performance. It is highly unsafe to drive with a bad or defective motor mount. While driving, if you have uneven vibrations, your car, most probably your mount, has gone bad.

How can I check my engine mounts?

The easiest way to check if your car engine mounts is to power brake the car, and from that, I mean to hold the brakes, put it in drive, and start accelerating gently; the car won’t move but keep somebody out, keeping the hood open. If it lifts reverse and bums back down, my friend, you probably have bad engine mounts.

Which engine does the mount fail first?

In a typical scenario, one motor mount fails before the others. A revving engine will rotate in the same direction as the crankshaft. That has a frequent characteristic of stretching one motor mount and compressing the others. Typically, the mount that stretches tends to fail first.

How long should motor mounts last?

In general, motor mounts don’t have a fixed replacement period, but a standard mount usually lasts 5 to 10 years before breaking down from age-related issues. Motor mounts generally get worn off by slamming the vehicle, gears over-revving, and too much power braking the engine before takeoff.

Conclusion

Motor or engine mounts are simple yet crucial parts of your engine. The motor mount replacement cost has been thoroughly mentioned here. If you see any such indications, get it checked immediately, as it can lead to much bigger problems and even fatal accidents. One should be cautious with one’s vehicle, as a precaution is always better than a cure!
