In an automobile lot of heat is produced due to the combustion, If this excess heat is not removed, the engine temperature becomes too high which results in overheating and viscosity breakdown of the lubricating oil, wear of the engine parts, due to thermal stress of the engine components failure may occurs in engine. The automobile engine utilizes a heat exchanger device, termed as radiator, in order to remove the heat from the cooling jacket of the engine. But for removing heat, area increasing is the limitation. To avoid this increasing area, we can use the nanofluids. Nano fluid is a fluid containing nanometer-sized particles, called nanoparticles which consist of a coolant with nanosized particles of metal oxides added within them. These addition of metal oxides increase conduction and convection coefficients, so that there is increase in the heat transfer rate. Among all the metal oxides copper oxide nanomaterials have unique thermal properties
