Re: Overheating

It's supposed to "puke" antifreeze. That is why there is an overflow tank. 210 is not overheating, plain water won't boil at that temp BUT there will be dynamic pressure (or whatever is the correct term) caused but the coolant expanding when heated. This pressure will cause some amount to be forced past the cap. It will be sucked back when the engine cools. Are you saying that the coolant tank overflows?
My truck will get to about 250-260 under severe conditions but it will not leak a drop past the overflow tank.
