How To Fix Motor Mounts
Now, there are generally only two reasons to replace a motor mount. 1) You are putting in a different engine that needs different motor mounts, or 2) You have cracked the old ones or they no longer snug up to the frame of the car or the engine block. It is important to remember that motor mounts should never really have to be replaced unless they are broken. If they are loose, it would be better to just go in and tighten them. In any case, let's go through a simple explanation of replacing your Motor Mounts. It will have to be general because with out knowing anything precise about the vehicle you are replacing them in; it is hard to give details.
1. Lifting the Engine
In order to get to the motor mounts and take them off to replace them, you will need to hoist the motor. This can be done with our without disconnecting the transmission or transaxle, but you will still need to go through the same process that you would to remove your engine. During the process of removing the engine, you will need to take off the bolts that hold the motor mounts to the frame of the vehicle. Then, you can freely lift the motor to get access to the rest of the mount on the block of the
2. Remove the motor mounts
There should be 2 to 4 bolts holding the motor mount onto the block of the engine and you will need to pull them off. If you are changing the bracket that holds the motor mount on the frame of the vehicle, you will also need to remove that.
3. Put on your new motor mounts
Replace the motor mounts on the block of the engine and the bracket onto the frame of the car if needed. Make sure your bolts are tightened as far as they can go without breaking them. This will keep you from having 'loose' motor mounts in the future. Let your engine down a little on the hoist until the mounts fit squarely into the brackets on the frame of the vehicle. Once they are lined up, replace the bolts that hold them together while you still have the engine slightly hoisted. This will help make your job easier.
4. Reconnect the engine
You will need to reconnect any parts, hoses, lines or harnesses that you have removed to hoist the engine up. Make sure everything goes back in its correct place.
5. Wiggle Room
Get inside the engine compartment and push down on the engine vigorously. You are checking to make sure your engine is securely in place and that there is no longer any signs of a 'loose' motor mount.
6. Test drive
As you can see it is possible to do this safely without disconnecting the transmission or the transaxle. Take your vehicle for a test drive to make sure you have repaired the necessary parts and that it is functioning properly.
