Gurgling and Boiling when shut down on hot days

My 93 fleetwood has 200+ thousand miles on it. When I stop after short drive on hot day it sounds like it is boing and gurgling? I see no fluid loss under vehicle or anywhere. My reservoir fills normally when running and goes back to radiator when cooled. I took cap off and ran with heater on and it boiled up and over a little. I can see the fluid in radiator bubbling with cap off. The cap "looks ok"?? Am I in trouble? help!!:bigroll::bigroll::bigroll:

I had the exact same issue, off and on for years with my 1993 Buick Roadmaster - essentially the same car you're driving. It was a series of very small leaks, with the last one fixed being the radiator itself. Once I replaced the radiator, all the trouble went away (even though I still may have a tiny leak somewhere I can't find.) My car had about 230,000 miles when I replaced the radiator, which was a pretty easy job, although I have very limited tools and not a lot of experience.
