In the cooling system of the automobile engine, the water which is used as a coolant is evaporated due to high engine temperature, so it needs to add some additives to the coolant water but they dont give high performance compared to adding some of Nano-particles. This work investigated
the heat transfer characteristics with Nano-fluid used in a radiator as vehicle engines coolant. The Nano-particles are introduced to a conventional coolantin certain concentrations resulted in, enhancing the ability to transfer heat, lowering the energy cost and theenvironmental impact. The
performance enhancement caused reduction of the radiator and the vehicle frontal areathat lowered the coefficient of drag consequently reduced the fuel consumption. Two types of Nano-particles; metal(Cu) and metal oxide (CuO) are used with different concentrations (1%, 2% and 4%) in conventional
coolant asa base fluid. Cooling of vehicle engine using radiator operated with different working fluids as water, coolant and modified coolant with Nano-particles are investigated. The conventional coolant with Nano Cu 2% had lowest exit temperature from the radiator and highest amount of
heat rejection, so it can be used as industrial Nano-coolant.
