ISUZU 4BD1 OIL COOLER CAP 5112800021 5-11280002-BN

ISUZU 4BD1 OIL COOLER CAP belongs engine parts , The function of the oil cooler is to cool the lubricating oil and keep the oil temperature within the normal operating range. On high-power reinforced engines, due to the large thermal load, an oil cooler must be installed. When the engine is running, as the viscosity of the engine oil becomes thinner as the temperature increases, the lubrication ability is reduced. Therefore, some engines are equipped with an oil cooler, whose function is to reduce the temperature of the oil and maintain a certain viscosity of the lubricating oil. The main function of the oil radiator cap is to prevent oil leakage .
