More particularly, the present invention relates to an oil cooler and a radiator tank assembly, in which a main body and a first connecting member are formed of aluminum to reduce costs and reduce the number of parts, To a radiator tank assembly.

The radiator is configured to prevent the temperature of the engine from rising to a predetermined temperature or more. The radiator circulates the high-temperature cooling water circulating in the engine while absorbing the heat generated by the combustion, passes through the radiator, It is a heat exchanger that dissipates heat to prevent engine overheating and maintain optimal operating conditions.

On the other hand, an oil cooler is provided in an automatic transmission to cool engine oil in a torque converter or a power transmission system. Since the temperature of the automatic transmission oil communicating with the interior of the oil cooler is higher than the temperature of the radiator, heat exchange is performed using the engine cooling water of the radiator and cooled.
