Engine mounts are crucial to your vehicle’s overall performance and stability. If you’ve noticed strange vibrations or noises, a worn-out engine mount could be the culprit.
When these mounts fail, they can lead to poor handling, excessive engine movement, and even potential damage to your car’s transmission and other components.
In this detailed guide, we’ll walk you through how to replace an engine mount so that your engine stays secure and running smoothly.
Why Replace an Engine Mount?
Engine mounts play an essential role in keeping your engine securely attached to your vehicle’s chassis. These mounts are typically made from rubber and metal and are designed to absorb vibration and reduce movement.
Over time, however, the rubber can wear out, crack, or break, causing increased engine movement and vibration. This not only affects driving comfort but can also lead to mechanical issues.
If you’re in the CV joint business or frequently purchase auto parts like CV joints, this knowledge is invaluable.
Whether you’re replacing engine mounts yourself or advising customers, understanding the process and the importance of proper engine mounting is key.
Can You Replace Engine Mounts Yourself?
Yes, replacing engine mounts can be a do-it-yourself (DIY) task if you have the right tools and a basic understanding of vehicle mechanics.
However, if you’re not confident, it’s recommended to consult a mechanic.
Installing engine mounts incorrectly can cause more harm than good, potentially leading to engine misalignment or other costly repairs.
The process involves safely lifting the engine just enough to remove the old mounts and installing the new ones in their place.
The key is to ensure that the engine is supported properly during the replacement. Let’s dive into the details!
Tools You’ll Need to Replace Engine Mounts
Prepare these essential tools before starting:
- Socket wrench set (for loosening bolts)
- Car jack and wood blocks (to safely raise the engine)
- Torque wrench (for tightening bolts)
- Protective gloves and safety glasses
Having these tools ready ensures a smooth and safe engine mount replacement.
Step-by-Step Guide to Replacing an Engine Mount
Here’s the complete guide on how to replace engine mount in your vehicle:
Step 1: Support the Engine
Park your vehicle on a stable, level surface and set the parking brake for safety. Use a jack to carefully support the engine, placing a wooden block between the jack and the oil pan to avoid damage. You only need to lift the engine slightly—just enough to relieve the pressure from the engine mounts.
Pro Tip: Don’t lift the engine too high, as doing so could stretch or damage other components, such as the hoses or exhaust system.
Step 2: Unbolt the Old Engine Mounts
Once the engine is supported, use a socket wrench to loosen the bolts that secure the engine mounts to the vehicle’s frame.
Depending on the car model, these bolts can be located on both sides of the engine. Be cautious and make sure to keep track of the bolts—you’ll need them to install the new mounts.
If the bolts are stuck due to rust or grime, use a penetrating oil to loosen them up. This is a common issue, especially in older vehicles.
Step 3: Lift the Engine
After the bolts are removed, carefully lift the engine just enough to take the pressure off the mounts. This is where the jack comes in handy.
Once the engine is slightly elevated, you should be able to slide out the worn or damaged engine mounts.
Safety Reminder: Be mindful when lifting the engine. Lifting it too high can cause strain on the hoses or other nearby components.
Step 4: Install the New Engine Mounts
With the old engine mounts removed, it’s time to install the new ones. Place the new mounts in the same position as the old ones and loosely hand-tighten the bolts. Make sure the mounts align correctly with the engine and the chassis to prevent misalignment.
Step 5: Torque the Bolts
Tighten the bolts according to the guidelines in your vehicle’s service manual with a torque wrench. It’s important to follow this step carefully, as incorrect torque—whether too tight or too loose—can lead to problems down the road. Ensuring the correct torque will keep the mounts secure and functioning properly.
Step 6: Lower the Engine
Once the new engine mounts are in place and secured, slowly lower the engine back into its resting position. Remove the jack and ensure everything is stable. Double-check that all the bolts are tightened properly.
