Abstract
The present invention provides an airtight reservoir in fluid communication with a cooling system of an internal combustion engine. This cooling system allows coolant to flow into the overflow bottle, thereby compressing air therein, and causing increases pressure. When the coolant again cools, the pressurized coolant flows back into the cooling system, thereby maintaining the system pressure above ambient.
