A Guide to Replacing Engine Mounts on the 2003-2016 Honda Pilot
If your Honda Pilot is vibrating, shaking, or clunking, a bad engine mount is the most likely cause.
- Vibration at idle while in gear is the #1 symptom of a bad mount on a Pilot.
- Models with Variable Cylinder Management (VCM), especially 2009-2015, are known to cause premature failure of engine mounts.
- For hydraulic or active mounts, OEM parts offer the best performance. Budget aftermarket brands like Anchor or Westar often lead to more vibration.
- Check for dark, greasy fluid leaks on or below the mounts, which is a definite sign of failure.
Is Your Pilot Shaking? Here's Why.
The most common sign of a failing engine mount is excessive vibration. You will feel it in the steering wheel, seats, and floorboards, especially when the Pilot is stopped at a light but still in Drive. This is because the mount has collapsed or leaked its internal fluid, and can no longer absorb the engine's natural vibrations. Other common symptoms include:
- Clunking or Thumping Noises: Loud clunks when you accelerate, brake, or shift from Park to Drive are a tell-tale sign. This is the sound of the unsecured engine moving and hitting other parts.
- Visible Engine Movement: If you have a helper put the car in gear and hold the brake while lightly pressing the gas, you may see the engine rock or lift excessively. An engine should not move more than an inch or two. 🎬 Watch: How to identify and locate a failing engine mount.
- Leaking Fluid: The front and side mounts on many Pilots are hydraulic (fluid-filled). If you see dark, greasy fluid on the mount itself or on the frame below it, the mount has failed and needs immediate replacement.
A Special Note on 2009-2015 Pilots and VCM
The second-generation Honda Pilot (2009-2015) uses a technology called Variable Cylinder Management (VCM) to improve fuel economy by shutting off some engine cylinders. However, this process creates vibrations that cause accelerated wear on the engine mounts, particularly the active front and side mounts. 🎬 See why the Honda VCM system causes these premature failures. It is a very common issue for these mounts to fail prematurely on VCM-equipped models. When replacing mounts on these vehicles, using high-quality parts is critical to avoid frequent replacements.
Choosing the Right Aftermarket Mount: Honesty About Quality
When it comes to engine mounts for the Honda Pilot, there is a significant difference between Original Equipment (OEM) and aftermarket parts. While aftermarket is much more affordable, the quality can be inconsistent, especially for a vehicle with active or hydraulic mounts.
Tier 1: Best Aftermarket Option
Beck Arnley: This brand is well-regarded for focusing on import vehicles and making parts that closely match original factory specifications. Forum users and mechanics often recommend Beck Arnley as a reliable choice if you are trying to avoid the high cost of OEM parts but still want good performance and longevity. It is often considered the safest bet in the aftermarket world for Honda mounts.
Tier 2: Economy / Budget Options
Anchor, Westar, DEA, MTC, Pioneer: These brands offer a significant cost saving, which is very appealing. However, for the Honda Pilot, using these mounts is a gamble. Many owners report that these budget-friendly mounts, which are often made of harder solid rubber instead of hydraulic fluid, cause more vibrations than the worn-out OEM part they replaced. While some people have no issues, many others experience poor fitment, increased cabin noise, and a short service life, leading them to do the job a second time.
Cost of Replacing Honda Pilot Engine Mounts
The total cost can vary greatly depending on which mounts are replaced and whether you use OEM or aftermarket parts. A single aftermarket mount can be very affordable, but replacing all of them at a shop with OEM parts can be expensive.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Mount (Single) | $34 - $186 |
| New OEM Mount (Single) | $250 - $900+ |
| Shop Labor (Per Mount/Job) | $357 - $524 |
| Total Professional Job (Aftermarket) | $400 - $700 |
| Total Professional Job (OEM) | $1,278 - $1,445+ |
Frequently Asked Questions
How many engine mounts does a Honda Pilot have?
The 2003-2016 Honda Pilot typically has a system of 3 to 5 mounts that secure the engine and transmission. This includes front, rear, and side (passenger) engine mounts, as well as transmission mounts. The most common to fail and cause vibration are the front and side hydraulic mounts.
Can I replace just one bad engine mount?
Yes, you can replace only the one that has failed. However, engine mounts wear out together. When one fails, it puts extra stress on the others, which may cause them to fail soon after. It is best practice to inspect all mounts and consider replacing them as a set if they are original and the vehicle has high mileage.
Is it difficult to replace a Honda Pilot engine mount?
It is a moderately difficult job for a DIY mechanic. It requires safely supporting the engine from below with a jack and wood block. Access to some bolts, especially for the front and rear mounts, can be very tight and may require removing other components like radiator fans 🎬 Watch this step-by-step walkthrough for replacing the front motor mount. or battery trays. If you are not comfortable with these steps, it is best left to a professional.
Is an OEM mount really worth the extra cost?
For many vehicles, aftermarket mounts are fine. However, for the Honda Pilot's sophisticated hydraulic and active mounts, OEM parts provide the best performance in eliminating vibrations. If you are sensitive to cabin vibration, especially on a VCM-equipped model, many owners would say yes, the OEM part is worth it. If budget is the main concern, a top-tier aftermarket brand like Beck Arnley is the next best choice.

The 2003-2016 Honda Pilot uses a combination of engine and transmission mounts. The key front and side engine mounts are typically hydraulic (fluid-filled) to dampen vibration. On models from 2009-2016, these are often 'active' mounts that are electronically controlled to counteract vibrations from the VCM system.
