Radiator Caps

By maintaining pressure on the cooling system, the boiling point of the water is raised. Coolant from the reservoir tanks to the radiator is also pumped through the radiator cap through a vacuum valve. In response to a drop in coolant temperature, the coolant contracts and creates a vacuum.
