[Phil Piotrowski]

After further review, the judges have changed there decision !
Ron Porter was the first to suggest that the radiator cap needed
replacement.

Thanks Ron.

I did replace the cap, at the time of the radiator.
But, that does sound like 'cheap' and easy thing to try.
Maybe I got a 'bum' cap.

Thanks,

Bad radiator cap. They lose pressure over time, and the pressure spikes
after shutoff. BTDT.

I replaced the radiator (is was leaking in the cold)
After the weather warmed up, and shortly after an oil change,
I noticed that while is stop and go traffic that the temp gauge Was near the
N in Normal (pretty hot from my experience) ! I pulled over, opened the
hood, and turned the engine off. Within a minute, the antifreeze was
bubbling out of the overflow tank ! When it cooled, it sucked all the
coolant out of the overflow tank. When I got home, I ran the engine with the
hood up, and the temp gauge would get to about the O, before the fan would
start and get the needle down to about the M. 

If I am moving on the highway, the temp  gauge is normally on the L in
Normal.

Several times, I have gotten home, put the car in the garage, and then in
the morning, the 'low coolant' light will be on. When I go to fill it, it
looks like the coolant boiled out again !  It is all over the floor. I have
checked the overflow tank, it does not leak. I did replace the thermostat
(it does have the 'giggle' value, and is rated for 190 degrees (AutoZone
said that was stock))

Any ideas as to why this is happening and how to fix/troubleshoot it ?

Thanks to all,
