<p>An engine cooling system for the internal combustion engine of a motor vehicle, such as a construction machine or the like which operates on uneven or sloped terrain, comprises a radiator having a lower core section and an elongated upper section or top tank separated from the core section by a sealed baffle and extending transversely to the longitudinal axis of the vehicle. The cooling system further comprises fluid conducting passages connected between the radiator and the engine, including a radiator supply line and a radiator return line connected between the core section and the engine. The cooling system also comprises a pair of fluid outlet ports located near the bottom of the top tank and spaced apart from each other in a direction transverse to the longitudinal axis of the vehicle. The cooling system also comprises a pair of sump or make-up lines, each connected between an inlet port in the radiator return line and an outlet port of the top tank to enable a faster fill rate and full use of the top tank's fluid capacity, especially in slope operations of the vehicle when the top tank is tilted toward one end or the other.</p> |
