• ### Pressure CapHow Car Cooling Systems Work

2021-2-11 · ­­The radiator cap actually increases the boiling point of your coolant by about 45 F (25 C). How does this simple cap do this The same way a pressure cooker increases the boiling temperature of water. The cap is actually a pressure release valve and on cars it is usually set to 15 psi.

• ### Are All Radiator Caps The Same Different Radiator Caps

2020-6-22 · A radiator cap will have two pressure measurements on it psi and kPa. Psi measures pound per square inch and kPa stands for kiloPascals. They are both used to calculate pressure and depend on whether the system uses imperial or metric units of measurement. Most caps are designed from 4psi (30kPa) to 30psi (205kPa) with the higher ratings

• ### How does a radiator cap work HowStuffWorks

2011-6-21 · The radiator cap acts as a release valve set to open at the maximum pressure point. Usually this is set at a density of 15 pounds per square inch (psi). When the fluid pressure inside the radiator exceeds 15 psi it forces the valve open allowing heat to escape and excess coolant fluid to overflow into the tanks on either side of the radiator.
