Abstract

An engine cooling apparatus capable of assuring an adequate air-water separating function in an arrangement wherein an air-water separating tank having a pressure valve is provided at a point along a coolant passageway. The apparatus has a closed circulating system constructed from an engine, a radiator and a coolant passageway connecting the engine and radiator, wherein, a coolant for cooling the engine is made to circulate in the closed circulating system from upstream to downstream, and air which mixes with the coolant is discharged outside the closed circulating system. The apparatus includes a branch passageway which branches off from a first intermediate portion of the coolant passageway and merges with the coolant passageway at a second intermediate portion thereof that is downstream of the first intermediate portion, and an air-water separating tank arranged in an intermediate portion of the branch passageway and having a pressure valve which opens to the atmosphere at a prescribed pressure in order to discharge the air to the outside of the closed circulating system.
