ABSTRACT:
A cooling system is provided for a vehicle with an internal combustion engine. The cooling system includes a high temperature cooling circuit and a low temperature cooling circuit that is separated from the high temperature cooling circuit. The high temperature cooling circuit cools the engine and includes at least one cooler. The low temperature cooling circuit cools an oil cooler and, if necessary, a charge air cooler and includes a cooler. The oil cooler may be connected with the high temperature cooling circuit so the oil temperature may be controlled within a narrow temperature range.
