Combines a radiator cap with a temperature gauge. But if your car normally operates at a very high coolant temperature, it is possible the cap may release pressure just shy of this temp. 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. They are manufactured from aluminum and are available in your choice of red, blue, … Remove the screw from the valve cap if there is one. The cooling system is pressurised, because the higher the pressure the higher the temp at which the water boils. Signs that all is not well under the bonnet will begin with the water temperature gauge. The ZERO PRESSURE tank will recover the expanded coolant as it increases in pressure. It's important to note when asking the question, what temperature should a radiator be set at, the answer doesn’t just relate to the radiator’s settings. How to Get a New Radiator Cap with the Proper Pressure Rating. You don't want to be standing in front of a car when it pops itself into drive...Rare, but why risk it?
