Abstract
An engine cooling apparatus has a heat storage tank for storing and maintaining the temperature of cooling liquid let out of an engine into an engine cooling circuit. The heat storage tank is mounted in a vehicle so that a housing retained to a lower portion of a tank body forms a lowermost end portion of the engine cooling circuit in a vertical direction. An inlet passage of the housing is provided with a drain port. A portion (drooped portion) of a cooling liquid channel upstream of the drain port is lower than the position of the drain port in the vertical direction.
