Abstract

In an automotive cooling system made up of a radiator, overflow bottle, engine and heater core members, a method of removing spent antifreeze therefrom involves applying air pressure at the highest vertical point of the cooling system members, and draining the antifreeze via the lowest vertical point thereof. A method of refill via the radiator or pressurized overflow bottle involves utilization of a refill element with vacuum and coolant prongs. Simultaneous vacuum and refill of coolant is achieved with the refill element.
