PENGARUH PENGGUNAAN VARIASI RADIATOR COOLANT TERHADAP EFEKTIFITAS PENDINGIN MESIN DAN LAJU KOROSI MATERIAL RADIATOR PADA MOBIL XENIA 1300 CC

The car radiator cooling system has an important role in maintaining engine performance so that it can remain optimal, the coolant cooling system itself is a chemical liquid that is specifically designed to have good effectiveness and prevent corrosion effects better than ordinary mineral water. The effect of using variations of
radiator coolant on the effectiveness of engine cooling and the corrosion rate of radiator material on xenia 1300 cc cars. Data collection was carried out at variations of speed set at 1000, 1500 and 2000 rpm. The temperature data collection was carried out for 10 minutes each. In testing the corrosion rate using a radiator material, namely aluminum 3102 with a potentiodynamic polarization test with the Corrtest test tool with CS studio5 software. The results of the effectiveness of the use of mineral water coolant on average is 16.53% and the corrosion rate is 0.0083695 mm/year, while the prestone water coolant is obtained on average 20.33% and the corrosion rate is 0.0074480 mm/year and the use of water coolant power coolant ( TOP1) 20.56% at a corrosion rate of 0.0075662 mm/year.
