ABSTRACT:
An evaporative cooling system features a reservoir which contains only sufficient coolant to fill the radiator when the engine is not in use and thus reduces the weight of the system. The remaining sections of the cooling circuit such as the upper section of the coolant jacket which are fairly resistant to corrosion are filled with air during non-use periods. The air is suitably purged out during engine warm-up and operation in accordance with the temperature differential which exists between the coolant jacket and the bottom of the radiator.
