Abstract: The purpose of this investigation was to ascertain the radiator's heat transfer rate. There are two types of hot fluid, namely water and an ethylene glycol-mixed water of 50%.The results indicate that the higher the flow of water flowing on the radiator pipe causes a radiator heat transfer rate increase. The use of antifreeze agents, such as ethylene glycol, in radiator systems is common in many applications to prevent freezing and overheating. However, the performance of radiator systems can be affected by the concentration of ethylene glycol in the coolant. In this experimental investigation, the effect of different proportions of ethylene glycol in radiator systems was studied. A radiator system was set up, and experiments were conducted with varying concentrations of ethylene glycol (40%, 50%, and 60% by volume) in water as the coolant. The performance of the radiator system was evaluated in terms of heat transfer rate, temperature drop, and overall thermal efficiency. The experimental results showed that the proportion of ethylene glycol in the coolant significantly influenced the performance of the radiator system. Higher concentrations of ethylene glycol resulted in reduced heat.
