    Q:
    How can the cylinder head be safely lifted off the engine for the 2000 GMC Jimmy? Posted by Customer
    A:
    To safely lift the cylinder head off the engine, you should outline the cylinders and bolt pattern on cardboard and mark the front of the engine. Then, loosen the head mounting bolts in 1/4-turn increments and store them in the cardboard holder. Carefully lift the head off the engine, and if it is stuck, only pry it at the overhang on the thermostat end. Place the head on a block of wood.
