Mercury Cougar Engine Mounts (1967-1972): A Complete Guide
Stop the shaking and clunking noises by choosing the right engine mount for your classic Cougar.
- Verify your engine type (small-block vs. big-block) before ordering, as the mounts are not interchangeable.
- Owners of 1967 models must be extra cautious, as most aftermarket mounts are for the 1968+ design and may require changing frame brackets.
- Always replace engine mounts in pairs to ensure even support and prevent premature failure of the new part.
- For stock cars, standard rubber mounts are fine; for modified or performance cars, consider heavy-duty Lakewood mounts for better durability.
Is Your Cougar's Engine Mount Failing?
The original rubber engine mounts on a 1967-1972 Cougar have endured decades of heat, oil, and stress. Over time, the rubber dries out, cracks, and collapses. When this happens, the engine is no longer held securely. This excessive movement can cause a variety of problems, some of which are more than just an annoyance.
Key Symptoms of a Bad Mount:
- Excessive Vibration: This is often the first sign. You'll feel more of the engine's shaking through the steering wheel, seats, and floor, especially when idling or accelerating.
- Clunking or Banging Noises: Loud clunks, particularly when you accelerate, decelerate, or shift gears, are a major red flag. This is the sound of the engine shifting and hitting other components.
- Visible Engine Movement: Open the hood, have a friend put the car in gear (with the brake firmly applied), and lightly press the accelerator. If you see the engine lurch or lift significantly, the mounts are likely shot. 🎬 See a demonstration of common symptoms and failure signs.
A Critical Note for 1967 Cougar Owners
Original-style engine mounts for 1967 small-block (289) Cougars are extremely difficult to find and have not been widely available for decades. Most aftermarket mounts sold as "1967-1972" are actually based on the 1968 design. To use these common aftermarket mounts on a '67, you may also need to replace the engine's frame stands with the 1968 version. Big-block (390/428) mounts are generally more consistent across these years. Always verify your specific engine and frame setup before ordering.

Finding a "New Old Stock" (NOS) Ford mount is nearly impossible and would be very expensive. Aftermarket parts are the go-to solution for virtually all owners. The main choice is between standard rubber replacements and heavy-duty or performance mounts.
| Brand Tier | Brands | Best For | Our Take |
|---|---|---|---|
| Standard Replacement | Anchor, DEA, Westar, Pioneer | Stock restorations, daily drivers, and owners who prioritize a smooth, quiet ride. | These brands provide an affordable, OE-style replacement designed to restore original ride quality. While some forum users report occasional fitment or longevity issues with budget brands, Pioneer is often reviewed more favorably than Anchor, DEA, or Westar. For a stock car, these are generally adequate. |
| Heavy-Duty / Performance | Lakewood | Modified engines, performance driving, and owners wanting maximum durability. | Lakewood "Muscle Mounts" use harder rubber (durometer) and a heavy-gauge steel frame, often with a safety interlock design. This reduces engine movement for better throttle response but will transmit more noise and vibration into the cabin. They are a great choice for high-horsepower applications. |
How Much Does It Cost to Replace a Cougar Engine Mount?
Replacing engine mounts is a common task for these classic cars. The parts themselves are affordable, but labor can add to the cost if you don't do it yourself. Prices below are estimates.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Mounts (Pair) | $35 - $90 |
| Shop Labor | $150 - $300 |
| Total Professional Installation | $185 - $390 |
Pro Tip: Replace in Pairs
Always replace engine mounts in pairs (left and right). If one has failed, the other is likely not far behind. Replacing both at the same time ensures even support for the engine and prevents the new mount from being stressed by an old, sagging one. Also, inspect your transmission mount at the same time, as it is subjected to similar wear.
Frequently Asked Questions (FAQ)
Is it hard to replace engine mounts on a 1967-1972 Cougar?
For a mechanic with some experience, it's a straightforward job. It requires safely lifting the car, supporting the engine from below with a jack and a block of wood, unbolting the old mounts, and installing the new ones. Difficulty is moderate, mainly due to working in tight spaces. It is a feasible DIY job if you have the right tools and safety equipment.

Yes, they are very different. Mounts for small-block engines (like the 289 or 302) are not interchangeable with mounts for big-block FE engines (like the 390 or 428). You must order the correct mount for your specific engine to ensure proper fitment and safety.
Are there any recalls for Cougar engine mounts?
No, there are no active recalls from the NHTSA for engine mounts on the 1967-1972 Mercury Cougar. Any failures are considered a result of normal wear and tear over the vehicle's long life.
What happens if I don't replace a bad engine mount?
Ignoring a failed engine mount can lead to more serious problems. The constant movement can damage radiator hoses, fan shrouds, exhaust manifolds, and transmission linkages. In extreme cases, the engine can shift enough to cause significant damage to the engine bay or create a serious safety hazard.
