Putting a new radiator in and figured I’d get a new cap to go with it. Currently has a 7psi cap on it, I thought they were 4psi systems? Does it make that much of a difference?

Pressure Caps make this much difference:

A 50/50 mix of water and antifreeze has a boiling point of around 223°F (106°C) at atmospheric pressure (0 PSI). However, this boiling point increases as the radiator cap pressure increases. For every 1 PSI of pressure, the boiling point increases by approximately 3°F.
