Abstract (en)

A coolant tank for receiving a fluid from the cooling system of an internal combustion engine includes a pressurized tank having a pressurized reservoir configured to contain the fluid and an overflow tank integrated with the pressurized tank. The pressurized reservoir includes an inlet port configured to receive the fluid from the cooling system, an outlet port configured to direct the fluid from the pressurized reservoir to the cooling system, a fill neck in fluid communication with the pressurized reservoir, and a pressure cap removably coupled to the fill neck. The overflow tank includes an overflow reservoir maintained at atmospheric pressure and configured to receive overflow fluid from the pressurized reservoir when the liquid of the cooling system expands. At least a portion of the fill neck is positioned within the overflow reservoir.
