Title: Radiator anti-freeze arrangement for evaporative type cooling system

Abstract

A boiling liquid cooling system is described for an engine, comprising: means defining in the engine a coolant jacket into which coolant is introduced in liquid state through an inlet port formed in the engine and from which coolant is discharged in gaseous state through an outlet port formed in the engine; a radiator into which gaseous coolant from the outlet port is introduced to be liquefied; a coolant container connected to the radiator to contain therein the coolant liquefied by the radiator; an electric pump by which the liquid coolant in the coolant container is pumped into the coolant jacket through the inlet port; conduit means connecting the outlet port, the radiator, the coolant container, the electric pump and the inlet port in this order to form a hermetically closed coolant circulation circuit; first and second coolant level sensors disposed in the coolant jacket to detect first and second coolant levels in the jacket respectively, the second coolant level being higher than the first coolant level; and control means for controlling the electric pump.
