     · The radiator pressure cap is a simple device that will maintain pressure in the cooling system up to a certain point. If the pressure builds up higher than the set pressure point, there is a spring loaded valve, calibrated to the correct pounds per square Inch (psi), to release the pressure. a partial vacuum is formed. The radiator cap on

  • Radiator Pressure Cap is the Cooling Systems Pressure

     · The Function of Radiator Pressure Caps Most radiator pressure caps keep the system pressure at 16 PSI so the engine coolant can get considerably hotter without the fear that it will boil off. If there is no pressure in the cooling system, the coolant will boil off.

  • Why Does My Coolant Bubble? It Still Runs

    A radiator cap functions as a pressure seal, and keeps the cooling system pressure raised. It also allows pressure and coolant to vent back to the expansion (overflow) reservoir. A malfunctioning radiator cap seal can allow air to enter the system, often producing bubbles in the expansion reservoir.
