Abstract
In an engine cooling structure in which a water pump for causing a cooling water or coolant to flow in a watercool engine is located at or near one end portion of a cylinder block in the direction of the cylinder alignment, coolant passages include a main coolant passage disposed in a cylinder head and the cylinder block, a radiator circulating passage leading the cooling water from the water pump through an engine body to a radiator core, a by-pass passage by-passing the radiator core, and a heater circulating passage leading the cooling water from the engine body to an air-conditioning heater. The radiator circulating passage and the by-pass passage are arranged so as to switch by a thermostat valve. The by-pass passage and/or the heater circulating passage are or is constructed so as to have a coolant return passage disposed in the cylinder block extending in the direction of the cylinder alignment.
