A cooler core, also known as a heat exchanger, is a specific cooler core used in certain models. Its function is to transfer heat from one fluid to another, typically between the engine coolant and transmission fluid or hydraulic fluid. This helps regulate the temperature of these fluids and prevent overheating, which can cause damage to the engine or transmission. The cooler core consists of multiple tubes or channels through which the fluids flow, with fins or plates that increase surface area for more efficient heat transfer. Overall, the cooler core plays an important role in maintaining proper functioning and longevity of a truck's engine and transmission.
