In today’s world of increasing demands of energy, heat management plays a crucial role for humans. As we look into automobile sector management of heat is now really important. Nano fluids are latest introduced cooling fluids containing ultrafine nano particles (1-100nm), which could increase thermal conductivity and heat transfer rate as compared to base fluid. These are suspended in base fluid which gets dispersed into base fluid. Nano fluid TiO2 has been investigated experimentally in this report to evaluate heat transfer in automotive radiator. Its size ranges from 10-100nm.A significant volume reduction of radiator has been observed and in contrary pumping power of pump is increased simultaneously.
