Heat transfer enhancement using TiO 2 and SiO 2 nanopowders suspended in pure water is presented. The test setup includes a car radiator, and the effects on heat transfer enhancement under the operating conditions are analyzed under laminar flow conditions. The volume flow rate, inlet temperature and nanofluid volume concentration are in the range of 2–8 LPM, 60– 80 °C and 1–2% respectively. The results showed that the Nusselt number increased with volume flow rate and slightly increased with inlet temperature and nanofluid volume concentration. The results of the analysis indicated that significant input parameters to enhance heat transfer with car radiator. These experimental results were found to be in good agreement with other researchers' data, with a deviation of only approximately 4%. PROBLEM STATEMENTMETHODOLOGYRESULT & DISCUSSIONCONCLUSION  Reduce the fuel consumption and the exhaust emission.  Reduce the cooling system weight and size required of the vehicle cooling system.  Reduce the circulation of the fluid inside the car radiator.  Reduce the fan operation time and cost.
