When your engine runs, it generates constant vibration and torque. Without something to hold it steady, that energy would shake your entire car—and damage nearby components in the process. Engine mounts solve this problem. They anchor the motor to the chassis while soaking up the shocks that would otherwise reach the cabin.
This guide breaks down what engine mounts do, the main types available, and how they relate to other suspension parts like the control arm. You'll also find a reference table of popular engine mounts for brands including BMW, Mitsubishi, Suzuki, Mazda, and Honda. By the end, you'll know how to identify a failing mount and choose the right replacement for your vehicle.
An engine mount—also called a motor engine mount or engine mounting—is the bracket and cushion assembly that connects your engine and transmission to the car's frame. It has two core jobs:
Support the engine's weight. A typical engine weighs several hundred pounds. Mounts hold it securely in place under acceleration, braking, and cornering.
Absorb vibration and noise. The rubber or fluid inside each mount dampens engine vibration before it travels into the chassis and cabin.
Most vehicles use three to four mounts, positioned to balance the load and control engine movement. When they work well, you barely notice them. When they fail, the difference is obvious.
Engine mounts fall into a few common categories. Knowing the difference helps you pick the right replacement.
Rubber engine mounts are the most widely used design. A solid block of vulcanized rubber sits between two metal plates, flexing to absorb vibration. They're durable, affordable, and simple to manufacture, which makes them the default choice for most passenger cars and commercial vehicles.
Hydraulic mounts use a fluid-filled chamber to dampen vibration more effectively than rubber alone. They're common in higher-end vehicles and engines that produce more vibration, since the fluid absorbs a wider range of frequencies.
The term "auto engine mounts" usually covers the full set of mounts in a vehicle, including the dedicated transmission mount. The transmission mount supports the gearbox specifically and works alongside the engine mounts to control drivetrain movement as a unit.
People often group engine mounts with the control arm because both are vibration-sensitive chassis parts—but they serve different roles. The control arm connects the wheel hub to the vehicle frame and manages suspension movement, while the engine mount holds the powertrain in place.
Both rely on rubber bushings to reduce vibration, and both wear out over time. Kaiping Shuntu Auto Parts, for example, manufactures engine mounts, bushings, and control arms together because they share similar rubber-to-metal bonding techniques. If you're replacing one worn rubber component, it's worth inspecting the others while you're under the car.
Worn engine mounts give clear warning signs. Watch for these symptoms:
Excessive vibration felt through the steering wheel, seats, or floor, especially at idle.
Clunking or banging noises when you accelerate, brake, or shift gears.
Visible engine movement that rocks more than normal when you rev the engine.
Cracked or leaking rubber visible on the mount itself during inspection.
If you notice any of these, have the mounts checked. A single failed mount puts extra strain on the others, speeding up wear across the whole set.
The right engine mount depends on your vehicle's make, model, and OE part number. Here's a reference table covering popular brands and example part numbers from a specialist manufacturer.
Vehicle Brand | Example Models | Sample OE / Part Numbers | Mount Type |
|---|---|---|---|
BMW | Various passenger models | Brand-specific OE numbers | Rubber / hydraulic |
Mitsubishi | Various passenger models | Brand-specific OE numbers | Rubber engine mount |
Suzuki | SX4, Swift, Vitara, Baleno | 11610-80J00, 11610-79J00, 11610-77J00 | Rubber engine mount |
Mazda | Various passenger models | Brand-specific OE numbers | Rubber engine mount |
Honda | Various passenger models | Brand-specific OE numbers | Rubber engine mount |
Mercedes-Benz (commercial) | 214, 314, 414, W210, W211 | 639 241 04 13, 203 240 13 17 | Rubber engine mounting |
Always match the OE number printed on your old mount—or look it up by your vehicle's model and engine size—before ordering. The same car can use different mounts depending on engine displacement and transmission type.
Use these criteria to narrow your choice:
Match the OE number first. This is the most reliable way to guarantee fit. Cross-reference the number stamped on your existing mount.
Confirm the position. Engines use front, rear, left, and right mounts. Order the specific one you need, or replace the full set if more than one is worn.
Choose the right material. For most everyday driving, a quality rubber engine mount is ideal. Choose hydraulic mounts only if your vehicle came equipped with them.
Buy from a specialist supplier. A manufacturer focused on engine mounts, bushings, and control arms typically offers better fitment data and quality control than a generalist seller.
For sourcing in bulk or finding parts for Japanese and German vehicles, manufacturers like Kaiping Shuntu Auto Parts specialize in engine mounts for Honda, Nissan, Toyota, Mazda, Ford, BMW, Suzuki, and Mercedes-Benz, with neutral packing and a 12-month warranty on many parts.
Engine mounts are small parts with a big job. They hold your powertrain steady and keep vibration out of your cabin—work that protects both your comfort and the rest of your drivetrain. The key takeaways: rubber engine mounts cover most everyday needs, hydraulic mounts suit higher-vibration applications, and matching the correct OE number is the surest path to a proper fit.
If you suspect a worn mount, inspect it alongside related parts like the control arm and bushings. Replacing them together saves time and keeps your vehicle running smoothly for the long haul. When you're ready to order, work with a specialist manufacturer who can confirm fitment by part number and stand behind the quality.
Engine mounts typically last 60,000 to 100,000 miles, though this varies with driving conditions and engine type. Rubber mounts can degrade faster in hot climates or with frequent hard acceleration. Inspect them during routine service once you pass 60,000 miles.
You can drive short distances, but it's not recommended. A failed mount allows excess engine movement that strains the remaining mounts, hoses, and drivetrain components. Replace a broken mount promptly to avoid further damage and a rougher, noisier ride.
A rubber engine mount uses a solid rubber block to absorb vibration, while a hydraulic mount uses a fluid-filled chamber. Hydraulic mounts dampen a wider range of vibration frequencies and suit higher-performance or higher-displacement engines. Rubber mounts are cheaper and ideal for most everyday vehicles.
Match the OE part number stamped on your existing mount, or search by your vehicle's make, model, year, and engine size. The same model can use different mounts depending on engine and transmission, so confirming the OE number is the most reliable method.
No. Engine mounts support the engine, while the transmission mount supports the gearbox. They work together as a set to control drivetrain movement, and the full group is often called "auto engine mounts." When several mounts are worn, replacing the complete set is often the best approach.
