How to Replace a LeSabre Motor Mount
by Robert Good
The Buick LeSabre model that was produced from 1991 to 1998 has two engine mounts, one on the right bottom side and another on the left bottom side of the engine. These engine mounts keep the engine mounted to the frame of the LeSabre and keep the engine from getting thrown around the engine compartment while the engine is running. Check the engine mounts every 25,000 miles, and replace them if they are in any way damaged.
Step 1
Raise the front end of the Buick LeSabre, using a floor jack. Place jack stands under the support rail toward the front right and left side of the frame directly behind the front right and left tire. Lower the Buick LeSabre onto the jack stands. Remove your floor jack from under the frame.
Step 2
Slide under the engine. Bring your floor jack with you, and position the jack under the center of the oil pan. Remove the securing bolt from the center of the motor mount, using a ratchet and socket.
Step 3
Raise the engine enough to relieve the weight of the engine. Pull the motor mount out from between the engine and the frame.
Step 4
Replace the old motor mount with the new one. Line up the hole in the middle of the motor mount with the holes on the frame and the engine.
Step 5
Replace the securing bolt, and tighten the securing bolt with the ratchet and socket.

Tips
- A flat, level surface will make this process much easier. Remove the right and left motor mounts the same way.
Things You'll Need
- Floor jack
- Jack stands
- Ratchet set
- New motor mounts
Warnings
- To avoid serious burns, allow the engine to completely cool off first. Remove only one engine mount at a time so that the engine is secured to the frame at all times.
