Water and ethylene glycol as ordinary coolants have been broadly utilized as a part of a car radiator for a long time. These heat exchange liquids offer low thermal conductivity. With the progression of nanotechnology, the new era of heat transfer fluids called, “nanofluids” have been developed and analysts found that these liquids offer higher thermal conductivity contrasted with that of routine coolants. This study concentrated on the utilization of a mixture of water and ethylene glycol based Al2O3 nanofluids in a cooling framework. Pertinent information, nanofluid properties and exact connections were obtained from literature review to examine the performance of a twin cylinder Diesel engine under various blends of nanofluid based coolants, furthermore, to research heat exchange improvement of a car radiator worked with nanofluid-based coolants. It was observed that, the performance of Diesel engine and heat transfer rate in cooling system framework enhanced with the utilization of nanofluids (with water and ethylene glycol the basefluid) contrasted with water and ethylene glycol (i.e. base liquid) alone. In the wake of leading the series of tests on Twin cylinder Diesel engine at 2%, 1% and 0.5% of nanofluid in basefluid, it was observed that performance of Diesel engine and heat exchange is upgraded better at 0.5% of Al2O3 nanofluid coolant.
