Pontiac Aztek Engine Mount Guide for 2001-2005 Models
Experiencing clunks or vibrations in your Aztek? A bad engine mount is the likely culprit.
- A clunking noise on acceleration is the #1 sign of a bad engine mount on an Aztek.
- The upper 'dog bone' torque strut is the most common mount to fail and is an easy, 30-minute DIY replacement.
- For the upper torque strut, budget-friendly aftermarket brands like Anchor, DEA, or Westar are a cost-effective choice.
- If you still have vibrations after replacing the top mount, the main hydraulic mounts are likely also worn.
Is Your Aztek Making a Clunking Noise?
A worn-out engine mount, especially the top 'dog bone' torque strut, is a very common problem on the 2001-2005 Pontiac Aztek. The rubber in the mount cracks and tears over time from engine heat and stress. When it fails, the engine can move too much, leading to several noticeable symptoms.
Symptoms of a Bad Engine Mount
- Clunking or Thudding Noises: This is the most common sign. You might hear a 'clunk' when you accelerate or shift from Drive to Reverse. This is the sound of the engine rocking back and forth.
- Excessive Vibrations: You may feel strong vibrations through the steering wheel, floor, or the whole car, especially when idling at a stoplight with the car in gear. If the vibration goes away when you shift into Neutral, it's a strong sign the mounts are bad.
- Visible Engine Movement: With the hood open and the parking brake on, have a helper firmly press the brake and shift the car between Drive and Reverse. If you see the engine rock back and forth more than an inch or two, the mount is bad. 🎬 Watch this video to see real-world symptoms of failed mounts.
- Visual Damage: A quick look under the hood might show obvious cracks or tears in the rubber part of the upper engine mount.
Don't Ignore the Signs
While you can drive with a bad engine mount, it's not recommended for long. Continued engine movement can put stress on other components like exhaust pipes, hoses, and the other engine and transmission mounts, leading to more expensive repairs.
Choosing the Right Aftermarket Mount
For the Pontiac Aztek, you have several aftermarket options. Not all mounts are created equal, but for certain applications, a budget-friendly brand can be a smart choice.
The Aztek has multiple mounts, including load-bearing hydraulic mounts and the upper torque strut ('dog bone'). The upper torque strut fails most often and is the easiest to replace.
- Premium Aftermarket (ACDelco): ACDelco is GM's official parts brand. Their aftermarket mounts, especially the hydraulic ones, are often considered the highest quality and are designed to dampen vibrations just like the original factory parts. For the main load-bearing mounts, choosing a quality hydraulic replacement from a brand like ACDelco can prevent future vibration issues.
- Standard Aftermarket (Anchor, Westar, DEA, Pioneer): These brands offer a good balance of affordability and quality. For the upper 'dog bone' torque strut, which is not a primary load-bearing or hydraulic mount, these brands are very cost-effective and perfectly suitable. Some users in forums report mixed results with these brands on other vehicles, with some experiencing shorter lifespans, but for the simple Aztek torque strut, they perform well.
Pro Tip: The upper torque strut mount is extremely easy to replace yourself in under 30 minutes with basic tools. You do not need to lift or support the engine for this specific part, making it a great DIY-friendly repair that saves a lot of money.

Frequently Asked Questions (FAQ)
Can I replace an Aztek engine mount myself?
Yes, the upper torque strut ('dog bone') mount is perfect for beginners. It's at the top of the engine and held by just a few bolts. You can do it in under 30 minutes without needing to support the engine. The main, load-bearing mounts (like the front right mount) are more difficult as they require safely lifting and supporting the engine with a jack.

The Pontiac Aztek has a system of several mounts. This includes two main load-bearing engine mounts, a transmission mount, and at least one upper engine torque strut (dog bone) to control engine rocking. Kits are often sold with 3, 4, or 6 pieces to replace multiple mounts at once.
Will a new torque strut fix all my engine vibrations?
It will fix the clunking and vibrations specifically caused by that failed upper mount. However, if your other main engine or transmission mounts are also old and worn, you might still have some vibration. If you replace the torque strut and still feel a lot of shaking at idle, inspect the other mounts next.
Are there any recalls for Pontiac Aztek engine mounts?
No, there have been no safety recalls issued by the NHTSA for engine mounts on the 2001-2005 Pontiac Aztek.
