Function of this part

The cooling system maintains proper engine operating temperature using components such as the radiator, charge air cooler, fan drive, and water pump. It removes excess heat from the engine and sometimes from charge air and transmission oil.

Why this part matters

Overheating can quickly damage an engine or transmission. Keeping the cooling system in good shape is essential for uptime, especially on heavy loads or in hot climates.

About the brand

Mack is known for building tough trucks and components for construction, vocational, and highway fleets that need reliable performance day after day.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.
