Engine mounts play a crucial role in securing the engine to the chassis of a vehicle while minimizing vibrations and noise. Over time, engine mounts can wear out, leading to excessive vibrations, engine misalignment, and even structural damage. Replacing engine mounts is essential to maintaining vehicle performance and longevity. In this guide, we will explore how to replace engine mounts, including tools required, steps involved, and important considerations.
An engine mount is a component that secures the engine to the vehicle’s frame or subframe while absorbing vibrations and shocks. Most vehicles have multiple engine mounts, each designed to stabilize the engine and drivetrain.
Rubber Engine Mounts – Common in most passenger vehicles, these use rubber material to absorb vibrations.
Hydraulic Engine Mounts – Filled with fluid for additional damping, providing a smoother ride.
Electronic Engine Mounts – Feature an active damping system that adjusts to engine load and speed.
Polyurethane Engine Mounts – More durable than rubber mounts, commonly used in performance vehicles.
Solid Engine Mounts – Made of metal, providing the highest level of stability but increasing vibration.
Excessive engine vibrations
Unusual noises (clunking, banging, or thumping)
Misaligned mounting an engine position
Increased cabin noise
Visible cracks or damage in the mount
Replacing mounting an engine requires mechanical knowledge and patience. Follow these step-by-step instructions for a successful replacement.
Tools Required
Floor jack and jack stands
Socket wrench set
Torque wrench
Pry bar
Engine hoist (optional for heavy engines)
Replacement engine mount bracket and bolts
Penetrating oil (for rusted bolts)
Safety gloves and goggles
Park the vehicle on a flat surface and engage the parking brake.
Open the hood and locate the engine mounts. Refer to the vehicle’s service manual for exact locations.
Use a jack to slightly support the mounting an engine. Place a wooden block between the jack and the engine to prevent damage.
Identify and loosen the bolts holding the engine mount bracket to the frame and engine block.
Apply penetrating oil to any rusted or stuck bolts to ease removal.
Carefully remove the old engine mount. If necessary, use a pry bar to loosen it.
Align the new engine mount with the mounting points.
Hand-tighten the bolts to hold the mount in place.
Gradually lower the jack to align the engine correctly with the new mount.
Torque the bolts to the manufacturer’s specifications using a torque wrench.
Double-check all connections to ensure proper alignment.
Remove the jack and inspect for any movement or misalignment.
Start the engine and check for abnormal vibrations or noises.
Take a short test drive to ensure the engine remains stable.
Inspect the engine mount after driving to confirm secure installation.
The cost of replacing engine mounts varies based on the type of mount and vehicle model. Below is a general cost estimate:
| Component | Estimated Cost |
|---|---|
| Standard Rubber Engine Mount | $50 - $150 |
| Hydraulic Engine Mount | $100 - $300 |
| Performance Engine Mount | $200 - $500 |
| Labor Cost | $150 - $500 |
| Total Estimated Cost | $200 - $1000 |
Labor costs depend on the complexity of the replacement and mechanic’s hourly rates.
Replacing an engine mount typically takes between 1 to 3 hours, depending on the complexity of the installation and the vehicle model.
Yes, if you have mechanical experience and the necessary tools. However, for complex mounts, professional assistance is recommended.
A damaged mount can cause excessive vibrations, misalignment, transmission problems, and potential engine damage over time.
Not necessarily. You can replace only the faulty mount, but for optimal performance, it’s recommended to replace all mounts if they show wear.
Driving with a broken engine mount is not advisable, as it can lead to severe engine misalignment and drivetrain issues.
Replacing an engine mount is an essential maintenance task that enhances vehicle stability and reduces vibrations. If you notice signs of worn-out mounts, it's crucial to address the issue promptly.
