I have noticed an odd condition in my radiator. 512 in motor with a be cool radiator/cap/resovior. I run distilledd water and water wetter only as this is primarily a track car. After normal operation, if the car sits for a week there will still be pressure in the radiator when I remove the cap. Not a whole lot, just enough to push a little water out. I keep the level in the radiator about 2 inches below the cap. I recently noticed that there was a bit of water on the floor under the radiator after the cat sat for a few days. Inspection revealed that the overflow resovior was full. Why is the radiator staying pressurized and not pulling water in the overflow back into the radiator after cooling down. Motor doea not run hot...typically 190-195 is as hot as it gets.
