Mazda Engine Oil Cooler

A Mazda engine oil cooler is actually a small radiator. The main function of Mazda engine oil coolers is to regulate the temperature of the oil that circulates the engine block. Like other Mazda auto parts, the engine oil cooler requires maintenance. Sometimes, you may even need to replace the engine oil cooler. When engine oil is too hot, it losses some amount of viscosity. Hence, it becomes less effective in lubricating the moving parts of the engine. However, it is inevitable that the oil becomes heated because the engine generates extreme amount of temperature. Although the water coolant takes away, the heat from the engine, the engine still has enough thermal energy to raise the temperature of the oil. Heated oil easily evaporates. But since the oil circuit is a closed system, the heated oil can cause the buildup of pressure. This pressure may interfere with the normal output of the engine.
