maybe mr. nickeleye could step and inform us on the actual facts of the cooling system and what affects boiling points directly.. i would hate to misinform others.. is it the radiator cap or the ethylene glycol that affects the boiling point. thanks

My experience, and more so, my research, has indicated that they both have good effects on raising the 'boiling point'.

Each pound of cap pressure raises the boiling point 3.25-degrees X cap pressure. So, if you're running a 15-lb. cap, then you've effectively raised the boiling point of your system 48.75-degrees or up to 260.75-degrees.
