A Guide to Engine Mounts for the 1999-2003 Volvo S80
Stop the shaking and clunking by choosing the right replacement engine mount for your S80.
- Vibrations at idle and clunking during acceleration are the most common signs of a bad engine mount on an S80.
- The upper torque mount (top of the engine) is the easiest to inspect and often fails first.
- Aftermarket mounts offer savings, but OEM-quality brands like CRP/Corteco are highly recommended for longevity and performance on this vehicle.
- Continuing to drive with a bad mount puts stress on other mounts, the transmission, and exhaust components, leading to more expensive repairs down the road.
Is Your S80 Shaking? It Could Be a Bad Engine Mount
If you feel a strong vibration in the steering wheel or through the cabin at idle, you may have a failing engine mount. This is a very common issue on the first-generation Volvo S80 as it ages. The rubber inside the mounts dries out, cracks, or gets soaked with engine oil, causing it to fail. A completely failed mount can cause loud clunking or banging sounds when you accelerate, brake, or shift gears. This is the sound of the engine physically moving and hitting other parts because it's no longer held securely.
Common Failure Points on the 1999-2003 S80
The most common mounts to fail are the upper engine torque mount (often called the 'top mount' or 'dog bone') and the lower torque mount. The upper mount is easy to see on top of the engine. If it's bad, you'll often see that the engine has sagged and the rubber is cracked or separated. The lower mount is underneath and helps control the engine's rocking motion. Because these two fail most often, it's a good idea to inspect them first.
Choosing the Right Aftermarket Engine Mount
When shopping for new engine mounts, you have a choice between Original Equipment (OEM) parts and aftermarket parts. For the S80, the quality can vary significantly between these options. While aftermarket parts are more affordable, some may not last as long or absorb vibrations as well as the original Volvo parts. Here’s how to think about the brands available:
Tier 1: OEM-Quality Aftermarket
These brands are known for manufacturing parts that meet or come very close to original factory specifications. They are an excellent choice for owners who want longevity and a smooth ride, similar to the original feel of the car. While they cost more than budget options, they provide better long-term value.
- CRP / Corteco: Corteco is a known Original Equipment Manufacturer for Volvo, meaning they likely made the part for Volvo in the first place. Choosing this brand is the closest you can get to buying a genuine part from the dealer.
- Beck Arnley: This brand specializes in parts for imported vehicles and focuses on matching the original part's form, fit, and function. They often source their parts from the same factories that supply the original automaker.
- Vaico: A well-regarded German brand that produces a wide range of OEM-quality parts for European vehicles.
Tier 2: Value-Focused Aftermarket
These brands offer a significant cost saving, making them a good option for budget-conscious repairs. However, be aware that owner experiences suggest these parts may have a shorter lifespan and might not dampen vibrations as effectively as OEM-quality mounts. They can be a practical choice if you are on a tight budget or don't plan on keeping the vehicle for many more years.
- URO Parts: A popular brand offering a wide range of affordable parts for European cars.
- Westar / DEA / Anchor: These are some of the largest aftermarket mount manufacturers, offering a budget-friendly alternative to OEM.
- Professional Parts Sweden / Pioneer Cable: These brands also provide cost-effective solutions for your Volvo.
Pro Tip: For this specific vehicle, many experienced owners and mechanics recommend spending more for an OEM-quality mount (like Corteco). Cheaper aftermarket mounts have been known to fail in as little as a year, leading to you doing the job all over again.

Frequently Asked Questions
How do I know for sure if my engine mount is bad?
The easiest way is a visual inspection. Look at the upper mount for cracks or separation in the rubber. For other mounts, you can have a helper put the car in 'Drive' with the emergency brake on and their foot firmly on the brake pedal. Briefly apply a small amount of throttle while you watch the engine. If the engine lifts or rocks more than an inch, the mounts are likely worn out. Warning: This should be done with extreme caution. 🎬 Watch: How to identify and locate a bad engine mount
Which engine mount should I replace first?
Always start by inspecting the upper torque mount on top of the engine and the lower torque mount underneath. These are the most common to fail and are responsible for most clunking noises during acceleration.
Can I replace just one mount, or should I do them all?
You can replace just the one that has failed. However, if one mount has failed due to age and mileage, the others are likely not far behind. A failed mount puts extra stress on the remaining good ones, causing them to wear out faster. If your budget allows, replacing them in pairs (e.g., both side mounts) or as a complete set is a good long-term strategy.
Is it difficult to replace an S80 engine mount myself?
It depends on the mount. The upper torque mount is very easy and can be replaced in under 30 minutes with basic hand tools. 🎬 See this quick walkthrough for replacing the upper engine mount The lower torque mount is also DIY-friendly but requires safely jacking up the car. 🎬 Watch: Step-by-step guide to replacing the lower torque mount The main side engine mounts are more difficult as they require supporting the engine from underneath with a jack and a block of wood before you can unbolt the mount.
