Product Description

Why use a Higher Pressure Radiator Cap ?

That same mix at 16 pounds per square inch (psi) of pressure boils at approximately 250 degrees. And the boiling point increases 2-3 degrees for each additional psi of pressure in the system.

So the over-simplified answer to the tech quiz is that, yes, a higher pressure radiator cap can help prevent overheating.
