Cylinder Head Removal
- Remove the coolant hose and spark plug from the cylinder head.
- Remove the engine hanger bolts, and keep track of which direction they are facing on the mounting plates.
- Mark the head nuts with 1 through 6 to follow a consistent crisscross pattern.
- Loosen the cylinder head nuts ¼ turn at a time to avoid head warp, with as many passes as you need.
- Lift the cylinder head off of the cylinder, followed by the gasket.
- Set your cylinder head aside, and set the old gasket in the trash.
