Comprehensive Guide to Checking and Replacing Automotive Engine Mounts

Engine mounts are crucial components that keep your vehicle's engine secured to the chassis. They can wear out, causing various issues. In this comprehensive guide, we will cover the steps to inspect, remove, and replace your automotive engine mounts.

Step 1: Gather Necessary Tools and Supplies

Gathering the right tools is the starting point for any repair work. Ensure you have:

  • Socket set and ratchet
  • Jack and jack stands
  • Screwdrivers
  • New engine mounts (if replacement is needed)
  • Wrench set
  • Torque wrench
  • Vehicle's service manual

Step 2: Secure the Vehicle

Find a flat, stable surface to work on, such as a garage floor. Engage the parking brake, and then use a jack to lift the front of the vehicle. Place jack stands under the vehicle for safety and lower the car onto them.

Step 3: Locate the Engine Mounts

The engine mounts are typically found connecting the engine to the frame or subframe. They might be in different locations depending on the vehicle model, so consult your vehicle's manual to locate them accurately.

Step 4: Inspect the Engine Mounts

Thoroughly inspect the mounts for signs of wear or damage, including:

  • Visible cracks or tears in the rubber
  • Excessive movement or looseness
  • Corrosion on metal parts

If you notice any of these signs, it's time to replace the mounts.

Step 5: Prepare for Removal

Before removing the mounts, support the engine using a jack with a block of wood. This will prevent any strain on other components.

Step 6: Removing the Old Engine Mounts

  1. Use the socket set to remove the bolts connecting the mount to the engine and frame.
  2. Take care not to damage surrounding components as you remove the old engine mount.
  3. Inspect the area for additional wear that may need attention.

Step 7: Preparing the New Mount

Before installation, compare the new mount with the old one to ensure compatibility. Clean the area where the mount will be installed to remove any dirt or debris.

Step 8: Installing the New Engine Mounts

  1. Position the new mount in place, aligning it correctly.
  2. Hand-tighten the bolts initially to ensure proper alignment.
  3. Use a torque wrench to tighten the bolts to the manufacturer's specified torque settings.

Step 9: Recheck Alignment and Tightness

Inspect the newly installed mount to ensure proper alignment and tightness. Check other nearby components for proper fitment as well.

Step 10: Lower the Vehicle and Test

Carefully lower the vehicle, remove the jack stands, and start the engine. Test-drive the vehicle and pay attention to any unusual vibrations or noises that may indicate incorrect installation.


Replacing engine mounts is a complex task, but with proper tools, patience, and this detailed guide, it can be done with confidence. Regular inspection of engine mounts is essential to catch issues early and ensure a smooth, stable ride. When in doubt, don't hesitate to consult a professional mechanic or your vehicle's manual for specific guidance.

Note: Always follow the safety guidelines and procedures specific to your vehicle. This guide is for general informational purposes, and it's essential to consult your vehicle's manual or a professional mechanic for precise details tailored to your car's make and model.
