Prepare Your Workspace
Park your S10 on a flat surface. Set the parking brake. Place wheel chocks behind the rear tires. Open the hood and disconnect the battery. This keeps you safe during the removal procedure.Support the Engine

This can cause injury, damage the transmission, or make the engine get stuck. Some people have needed extra help to fix problems caused by poor support.
Locate the Motor Mounts
Find the driver’s side motor mount and the passenger side motor mount. On the 4.3 engine, these sit near the front of the engine, attached to the frame. You’ll see the engine mount bolts holding them in place.Remove Splash Guard or Access Wheel Well
Sometimes, you need better access to the engine mount bolts.Check if your S10 has a splash shield.
If you see plastic clips, use a flathead screwdriver or trim tool to pop them out.
For metal bolts, spray them with a penetrating oil like WD-40 Specialist Penetrant, PB Blaster, or Kroil. Wait 10-15 minutes.
Use the right socket and a breaker bar for stubborn bolts.
If a bolt spins but won’t come out, grab locking pliers or a bolt extractor.
Clean the threads before you reinstall the splash guard.
Remove Engine Mount Bolts
Use a socket and wrench to loosen the engine mount bolts. You’ll find bolts on both the driver’s side motor mount and the passenger side motor mount. Remove the nuts from both sides. If you have trouble reaching the bolts, try going through the wheel well or splash guard opening.Tilt the Engine for Better Access (Optional)
If you can’t reach the top bolts, you can tilt the engine by lowering the rear crossmember.Remove the cab-to-frame bolts and jack up the cab if needed.
Take out the crossmember and tilt the transmission down.
Use a long extension and swivel socket (usually 14mm or 15mm) to reach the engine mount bolts.
Remove the driveshaft and most of the exhaust to drop the crossmember.
Watch for fluid leaks when you tilt the transmission.
Remove the Engine Mounts
Once you have all the bolts out, carefully lift the engine mount out of the frame. Repeat the removal procedure for both sides. Now you’re ready to replace engine mount parts or start the installation procedure.
Tip: Always keep track of which bolts go where. Lay them out in order or take a quick photo before you start the repair.
Troubleshooting
Sometimes, the engine mount removal procedure does not go as planned. Here are some tips to help you with common problems:
Stuck or Seized Bolts
Use a true penetrating oil. Look for products labeled as ‘penetrating’ like PB Blaster, Liquid Wrench, or AiroKroil.
Avoid household sprays. They don’t work well on engine mount bolts.
Let the oil soak for at least 10-15 minutes before trying again.
For rusted or corroded bolts, use a premium penetrating oil instead of heat. This is safer and works better.
Hard-to-Reach Bolts
Try accessing the bolts through the wheel well or after removing the splash guard.
Use a long extension and a swivel socket for tight spots.
If you still can’t reach, lower the rear crossmember and tilt the engine as described above.
Engine Shifts or Misalignment
Double-check your engine support before you start the removal.
If the engine moves, stop and reposition your jack or hoist.
Never let the engine hang by the transmission or other components.
