Using the pump handle, start pumping the tester and see if the gauge can store the pressure. You should see the gauge read a minimum of 15 pounds. If this amount begins to fall, then the pressure cap must be malfunctioning.
Your problem may simply be a loose or damaged cap not keeping coolant where it needs to be. The radiator cap is designed to allow access to fluids in a ‘closed’ system.
