In an IC Engine, the cooling system is responsible to remove additional heat from the engine. The cooling system of an ICE consist of many parts that water jacket of the cylinder block and cylinder head of the engine is one of them. In this paper, the effect of redesigning of coolant inlet and outlet location on the temperature distribution of the engine body, engine coolant and water pump power is investigated. Both hydraulic and thermal governing equation is solved numerically. After the simulation and validation of the coolant flow in the water jacket, some changes in location of coolant inlet are considered. The obtained results show that both the pressure gradient and the flow rate of the coolant will reduce when the new inlet locations are used. It was showed that, the reduction of the pressure gradient and the flow rate, decreased the input power of the water pump and consequently increased the output power of the engine. The proposed idea in this paper can be used in the intelligent cooling systems of the internal combustion engines.
