The Radiator Oil Cooler Core is used to dissipate heat from the engine oil, which becomes heated during the combustion process. By transferring this heat to the surrounding air or cooling fluid, the core helps maintain the oil at an optimal operating temperature, preventing it from becoming too hot and losing its lubricating properties. It helps protect the engine components from excessive heat, which can lead to premature wear and reduced efficiency.Attributes:• Air Fin type 7366 square wave 6.4 Fins/Inch • Turbulator Type 7042 Lanced offset 6.8 Fins/InchApplications: The Radiator Oil Cooler Core is used in the Oil cooler unit for maintaining the proper operating temperature of the engine oil, thereby safeguarding the engine and promoting optimal performance.
