The automotive industry's demand for engines with the highest performance, efficiency, and design has steadily increased. Water is typically used as the coolant when using a radiator as an engine cooling component. The radiator's coolant mixing process removes heat from a liquid-cooled system. Coolant is circulated by pumps, and heat is removed by radiators. Radiator design and size optimization are required for an effective cooling rate. Due to some limitations in the design optimization process, testing alternate coolants to water can increase efficiency. Thus, a car radiator's thermal performance was enhanced in this experiment utilising several coolants. To the base fluid, a mixture of water and water with differnt percent concentrations of Al2O3 and CuO particles were added, and the fluid's properties for heat transfer were then assessed. "To analyse the performance of the heat transfer characteristics of water/anti-freezing based fluid as a coolant for vehicle radiators," is the stated goal of the current paper. 698.84 was the highest Reynold's number. The lowest Nu Number calculated by Al2O3 contained fluid was 499.1. When comparing Al2O3 and CuO and Water only fluids, the highest Nu for H2O is 10.79, the second highest for CuO fluid is 6.49, and the lowest value for Al2O3 contained fluid is 5.66.
