Signs of a Failing Engine Mount in Your Buick Century
When an engine mount fails, the symptoms are usually hard to ignore. Because these mounts are designed to absorb vibration, their failure often results in more noise and shaking inside the car. For this generation of Buick Century, a common complaint is a sudden jolt or shake when shifting from Park into Reverse.
Look out for these common signs:
- Increased Vibrations: If you feel more engine vibration than usual through the steering wheel, floor, or seats, especially at idle, your mounts may be worn.
- Clunking or Thudding Noises: Loud clunks or thuds when you accelerate, decelerate, or shift gears are a classic sign of a broken mount allowing the engine to move too much.
- Visible Engine Movement: You can often see a failed engine mount in action. With the hood open and the parking brake set, have a helper shift the car from Drive to Reverse while holding the brake.

Choosing the Right Aftermarket Mount
For a vehicle from the 1983-1996 model years, original equipment (OEM) parts are often discontinued or prohibitively expensive. The most practical and common choice is a new aftermarket part. Brands like Anchor, DEA, and Westar are widely available for the Buick Century.
Here’s an honest assessment of these brands based on owner experiences:
- Brand Tier: Anchor, DEA, and Westar are generally considered budget-friendly or economy brands. They offer a low-cost solution to fix a failed mount.
- Quality: Experiences with these brands are mixed. Some owners report that they fit well and last for years, while others have experienced premature failure. The rubber may not be as durable as the original, but for an older, high-mileage vehicle, they are often seen as a perfectly acceptable repair to get the car back to running smoothly.
Pro Tip: Replace in Sets
Your Buick Century has multiple engine and transmission mounts. When one fails, it puts extra stress on the others. For the best results and a longer-lasting repair, it's often a good idea to replace the mounts in sets (e.g., both front mounts) or replace all of them if they are original and show signs of age.

Frequently Asked Questions
How many engine mounts does my 1983-1996 Buick Century have?
These vehicles typically have a few mounts securing the engine and transaxle assembly. This includes mounts on the right (engine) and left (transaxle) sides, as well as torque struts (often called 'dog bones') that control the engine's twisting motion.
Can I replace just one bad engine mount?
Yes, you can replace only the one that has failed. However, since all the mounts are the same age, the failure of one often means others are not far behind. Replacing them in sets can save you from having to do the same job again in the near future.
Is replacing an engine mount a DIY job?
For a mechanically inclined person with the right tools, yes. The job requires safely supporting the engine with a jack and a block of wood or an engine hoist before unbolting the old mount and installing the new one. If you are not comfortable with this, it is best to leave it to a professional mechanic.
