Lightbulb DT466 Coolant Overflow

My 1997 International with a DT466 has an odd problem. Its been stored for about a month and I went to check on it, when I took the radiator cap off it was pressurized and started leaking/pouring out. I left the cap off and it stopped after a bit.

I started it up and felt no pressure on the coolant bottle with my hand. After running it a bit the coolant level went from the cap down to the max line. Ran and drove fine, temp held steady at 180.

I parked it and it was fine, no leaks.

This morning there is a small puddle of radiator fluid that leaked out.

The oil is clean. No smoke in the exhaust. Doesn't seem to be loosing radiator fluid.

Any idea why it would be overflowing after sitting for a month?
