    traditionally forced convection heat transfer in a car radiator is performed to cool circulating fluid which consisted of water or a mixture of water and anti-freezing materials like ethylene glycol (eg). in this paper, the heat transfer performance of pure water and pure eg has been compared with their binary mixtures. furthermore, different amounts of al2o3 nanoparticle have been added into these base fluids and its effects on the heat transfer performance of the car radiator have been determined experimentally. liquid flow rate has been changed in the range of 2–6 l per minute and the fluid inlet temperature has been changed for all the experiments. the results demonstrate that nanofluids clearly enhance heat transfer compared to their own base fluid. in the best conditions, the heat transfer enhancement of about 40% compared to the base fluids has been recorded.
