There are 2 gaskets on our 16 lb radiator pressure caps, one (the lower one) unseals when the cap opens at 16 lbs. The other (upper that seals at the top of the neck) SHOULD hold to a substancially higher pressure point for safety reasons (This is the pressure I am looking for) I realize our systems would/could have multiple failure points above 22 lbs and am not running this system above a 16 lb cap. This system is failing at the upper gasket at the temps stated above for clarity. In an overheating condition, idealy the overflow would happen in the overflow tank then down the overflow hose to the ground.
Thanks,
Angelo
