Thanks Bruce, mine was a little low so I topped it off. Then I started wondering about what do they do for expansion when it gets hot. Is there an expansion tank somewhere or does the air gap on the top at the inspection point serve that purpose?

Yes, that is what the air gap is for. The 4.4 S/C in the STS had a small coolant tank where you could check the fluid level.

What is meant by the "Important" statement "Make sure that ...................... and that the pump is not in the ON position" ?
What is meant by pump being in the ON position. I am not aware of any way to turn off or on the "pump". Whatever that is.

The pump is on the right or passenger inner fender. The ON position would be with the ignition in the RUN position.
