Chevrolet Caprice Engine Mount Guide for 1980-1986 Models
Stop the shaking and clunking noises in your classic Caprice by choosing the right replacement engine mounts.
- The most common signs of failure are heavy vibration at idle and loud clunking noises when accelerating.
- Choose standard rubber mounts for a quiet, comfortable ride or upgrade to polyurethane for durability at the cost of increased vibration.
- Replacing engine mounts is a DIY-friendly job but requires safely supporting the engine with a jack.
- Always replace engine mounts in pairs and inspect the transmission mount at the same time.
Is Your Caprice Shaking or Clunking?
The engine mounts on the 1980-1986 Caprice are simple, but they take a lot of abuse. After decades of use, the original rubber breaks down, cracks, and collapses. When this happens, you'll notice some clear signs that it's time for a replacement. The most common symptom is a new, excessive vibration that you can feel in the steering wheel, seats, or floor, especially when the car is idling in gear. You might also hear a loud 'clunk' or 'thump' from the engine bay when you accelerate, brake, or shift from drive to reverse. This noise is the sound of the engine itself moving and hitting other components because the mount is no longer holding it securely.
Choosing the Right Aftermarket Mount
Since original GM mounts for this car are generally not available new, you'll be choosing from aftermarket brands. They fall into two main categories:
Standard Rubber Mounts (OEM Style)
Brands like: Anchor, DEA, Westar, Pioneer
These are designed to be direct, factory-style replacements. They use rubber to absorb vibrations, aiming to restore the original smooth ride. They are the most affordable option. However, be aware that quality can be inconsistent with budget brands. Forum users report mixed experiences, with some having mounts fail in a short time, while others have no issues. These are a practical choice for a daily driver where comfort is the priority, but don't expect the same lifespan as the original parts.
Pro Tip: When replacing engine mounts, it's highly recommended to also replace the transmission mount. They wear out at a similar rate, and a new transmission mount ensures the entire drivetrain is properly supported.
Performance Polyurethane Mounts
Brands like: Energy Suspension
For those looking for durability and performance, polyurethane (often called 'poly') is a popular upgrade. These mounts are much stiffer and more durable than rubber and will resist oil and road grime better. They significantly reduce engine movement, which can improve throttle response. The main trade-off is a noticeable increase in cabin vibration and noise (NVH - Noise, Vibration, and Harshness). Polyurethane is not as soft as rubber, so more of the engine's vibrations are transferred to the car's frame. Some users also report needing to make minor modifications for a perfect fit.
Cost to Replace 1980-1986 Caprice Engine Mounts
| Part Type | Cost Range (Parts Only) |
|---|---|
| New Aftermarket (Rubber, e.g., Anchor, DEA) | $15 - $30 per mount |
| New Aftermarket (Polyurethane, e.g., Energy Suspension) | $35 - $50 per mount |
| Shop Labor | $150 - $350 |
Note: Costs are estimates and can vary based on your location and specific vehicle configuration. Labor costs typically cover replacing both engine mounts.
Frequently Asked Questions (FAQ)
How many engine mounts does my Caprice have?
Your 1980-1986 Caprice has two engine mounts, one on each side of the engine, and one transmission mount at the rear of the transmission. It is best practice to inspect all three when you suspect one has failed.
Can I replace just one broken mount?
It is strongly recommended to replace engine mounts in pairs. If one has failed due to age and wear, the other is likely not far behind. Replacing only one can put extra stress on the new part and the older mount on the other side.
Is it hard to replace the engine mounts myself?
For a person with some mechanical experience, this is a manageable DIY job. The process involves safely supporting the engine with a floor jack and a block of wood, unbolting the old mounts, slightly raising the engine, and swapping in the new parts. Always use jack stands for safety when working under the vehicle.
Are there any recalls on Caprice engine mounts?
No, there are no specific recalls or technical service bulletins (TSBs) from GM or the NHTSA for engine mount failure on the 1980-1986 Chevrolet Caprice. This type of failure is considered normal wear and tear for a vehicle of this age.
