Claim:
A method of refilling coolant from a fluid cooling system of an engine, the fluid cooling system having a surge tank or pressure cap, the method comprising the steps of: sealingly connecting a storage tank of a coolant management tool to a drainage port of the fluid cooling system, wherein the drainage port is located at the bottom of the fluid cooling system, wherein the storage tank stores the coolant to refill the fluid cooling system, and wherein the coolant management tool has a three-way valve selectively controlling fluid communication between the storage tank and the fluid cooling system; installing a vacuum module to the surge tank or pressure cap; establishing a vacuum within the fluid cooling system; opening the three-way valve selectively controlling fluid communication between the storage tank and the fluid cooling system; and maintaining the vacuum while drawing at least a portion of the coolant from the storage tank up through the drainage port, up through the fluid cooling system, and to a level just upstream of the vacuum module.
