Chevrolet Blazer Engine Mount Guide (2019-2025)
Feeling a new vibration in your Blazer? It might be time to check your engine mounts.
- The most common sign of a bad engine mount in your Blazer is increased vibration at idle or a clunking noise when accelerating.
- For the best ride quality, OEM mounts are recommended; aftermarket options like Anchor are cheaper but may increase cabin vibration.
- While a DIY replacement is possible for experienced mechanics, it requires safely supporting the engine.
- No specific recalls or TSBs have been issued for 2019-2025 Blazer engine mounts as of early 2026.
Is Your Blazer's Ride Getting Rough? Signs of a Failing Engine Mount
Engine mounts are built to last, but they do wear out over time. Since the 2019+ Blazer is a relatively new vehicle, widespread failures are not yet common. However, as these vehicles accumulate miles, mount issues can arise. A bad mount can cause a range of problems, from annoying vibrations to potential damage to other parts. Here’s what to look and listen for:
🎬 Watch: How to identify common symptoms of failed motor mounts- Increased Vibrations: This is the most common symptom. You might feel a noticeable vibration through the steering wheel, floor, or seats, especially when the Blazer is idling in gear at a stoplight.
- Clunking or Thumping Noises: Loud clunks or bangs from the engine bay during acceleration, braking, or shifting gears can indicate a broken mount is allowing the engine to move too much and hit other parts.
- Visible Engine Movement: A healthy engine should have very little movement. If you have a helper put the car in drive (with the brake firmly pressed) and gently apply the gas, you can watch the engine. If it rocks or lifts excessively, a mount is likely bad. 🎬 See this guide on how to locate a bad mount
Don't Ignore a Bad Mount
A completely failed engine mount can put extra stress on the remaining mounts, causing them to fail sooner. In severe cases, excessive engine movement can damage hoses, wiring, and even the transmission linkage or exhaust system.
Choosing a Replacement: OEM vs. Aftermarket
When it's time for a replacement, you have a choice between Original Equipment Manufacturer (OEM) and aftermarket parts.
- OEM Mounts: These are the exact same parts your Blazer was built with. They guarantee a perfect fit and the intended level of vibration absorption. For a newer vehicle, OEM is often the safest bet for maintaining the original ride quality, but it comes at a higher price.
- Aftermarket Mounts (Anchor): Aftermarket brands like Anchor offer a more budget-friendly alternative. Anchor has been making mounts for decades and designs them to meet original standards. However, owner feedback across various vehicle models is mixed. Some users report that aftermarket mounts can be harder or less flexible than OEM, leading to a noticeable increase in vibration after installation. Others have reported fitment issues requiring modification to install. For a part where vibration control is the main job, this is a critical consideration.
Pro Tip: Which to Choose?
If your priority is restoring the original smooth, quiet ride of your Blazer, investing in an OEM mount is the recommended path. If budget is your primary concern, an aftermarket mount from a brand like Anchor can get the job done, but be aware there is a risk of increased cabin vibration compared to the original part.
Cost to Replace a Chevrolet Blazer Engine Mount
The total cost depends on the part you choose and who does the work. Your Blazer has multiple mounts, and prices can vary for each. The passenger side mount is often the first to fail as it bears the most engine torque.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Mount (e.g., Anchor) | $82.85 - $93.78 |
| New OEM Mount | $136+ |
| Shop Labor | $289 - $424 |
| Total Professional Replacement (Aftermarket Part) | $372 - $518 |
| Total Professional Replacement (OEM Part) | $425 - $560 |
Costs are estimates and can vary based on your location, which mount needs replacement, and local labor rates.
Frequently Asked Questions
How many engine mounts does my 2019-2025 Blazer have?
Most modern front-wheel-drive vehicles like the Blazer have a system of three or four mounts that support the engine and transmission. This typically includes a right-side engine mount, a left-side transmission mount, and one or two torque struts (or dog-bone mounts) to control rocking.
Can I replace just one bad engine mount?
Yes, you can replace only the failed mount. However, it's a good practice to inspect all of them. Mounts wear at a similar rate, and a new, stiff mount can put extra stress on the remaining older, softer mounts, potentially causing them to fail sooner.
Are there any recalls for the Blazer engine mounts?
As of early 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Chevrolet for engine mount failures on the 2019-2025 Blazer. Any issues would be handled as individual repairs.
Is replacing an engine mount a DIY job?
This is a job for an experienced DIYer. It requires safely supporting the engine with a jack and block of wood or an engine support bar before unbolting the old mount. Access can be tight, especially for the mounts near the firewall or under the battery. If you are not comfortable supporting the weight of your engine, it's best to leave this job to a professional mechanic.
