Abstract
An apparatus to supply liquid coolant, to and to transfer coolant from, an engine and radiator coolant system, comprising a supply tank having a coolant fill inlet, which is closable, and a coolant delivery outlet to deliver coolant via a hose to the engine and radiator coolant system; an air pressurization inlet to the tank to receive compressed air that forces coolant from the tank via the outlet; and structure responsive to a predetermined coolant flow from the tank for relieving pressurization of the tank, whereby coolant flow is then interrupted.
