Do you have a radiator pressure pump? It goes on the radiator where the radiator cap goes. Pressurize it and see if it leaks down

Easy way to check for compression entering the cooling system is drop the end of the overflow hose in a cup of water with the engine idling. You'll see a constant trail of bubbles coming from the hose end.
You don't have to borrow any pressure tester, and you'll find out almost instantly.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
