A radiator cap for closing the filler neck of a vehicle cooling system. Included in this cap is the conventional function of being able to automatically release the pressure of the engines cooling system, when said pressure overrides the radiator caps valve assembly. Also included is the conventional function of being able to allow the reclamation of coolant from an external container, when the atmospheric pressure exceeds the pressure inside the engines cooling system. This invention includes a painted numerical display embedded in the top surface of the cap. A temperature probe extends from the bottom surface of the cap and is mechanically connected to the needle indicator, mounted over the painted numerical display. Upon securing the cap to the filler neck, the temperature probe senses the temperature of the associated cooling system, this information is mechanically delivered to the needle indicator, which will correspond to certain calibrated numbers on a painted display, to be read by the user. The cap enables a user to ascertain the cooling system temperature at the filler neck site efficiently, and reliably.
