ABSTRACT:
A cooling system for an engine is disclosed. In a first embodiment, the cooling system may comprise a heat exchanger, a pump coupled to the heat exchanger, an EGR cooler coupled to the pump, and a first valve coupled to the EGR cooler and the heat exchanger. When the first valve is in a first position, the first valve directs a coolant to the heat exchanger and when the first valve is in a second position, the heat exchanger is bypassed and coolant flows directly to the pump. It is an advantage for a cooling system to utilize a valve to maximize the rate a coolant flows throughout the system when the valve is in an open position and also to warm up an engine when the valve is in a closed position.
