In this work, an experimental study has been performed to evaluate the effect of the tube insert in an engine cooling system (the radiator of Peugeot 405). Experimental setups, as an automobile cooling system, was simulated to perform experiments for assessing the effect of the tube insert in the thermal performance of the radiator. A tube insert with a thin wire of a sinusoidal profile steel tube, as a turbulator, was used in the radiator. Results showed that when tube inserts were used, we reached 23% average value, 5% minimum value and 41% maximum value for the heat transfer coefficient enhancement. Also, experimental data exhibited a good agreement with correlations of other researchers.
