Hi tom my name is mike i came across this while searching google. My friends 1999 Malibu is also running hot and doesn't have any heat. he runs out of coolant very fast after refilling it and he is going throught coolant resivor caps constantly. where the top of the cap breaks off and he must pry the rest of the cap off. 3 in the last month. there is a small pool of collant under where the thermostat is. please reply back if you have any ideas. thank you

Moved your post and isolated it to be it's own. So far from the info it sounds like a head gasket issue. I invite other ideas always here!

If that is a V6, they are notorious for leaking intake manifold gaskets.
You need to pressure test the cooling system to find out.
