Mack, Volvo Radiator - Mack HDC010194PA, Volvo Truck 2400939, Northern Radiator SCSI239049, Reach Cooling 42-10406

When your Mack or Volvo truck needs a reliable cooling system repair, the Reach Cooling 42-10406 aftermarket radiator delivers a direct, no-hassle replacement that meets or exceeds original equipment specifications. This unit replaces Mack HDC010194PA and Volvo Truck 21504542, and it also cross-references Northern Radiator 239049, Active Radiator Supply Company 7300-26, 1-800-Radiator 2400939, and Serck FLA000625, making it easy to confirm you have the right part before it ships. The aluminum core is built with B-type tubes featuring central reinforcement for greater pressure tolerance, deep extrusion headers that resist the stresses of vibration and thermal cycling to virtually eliminate tube-to-header leaks, and folded fin edges for improved heat disbursement. Thermal expansion cuts extend core life by allowing natural expansion and contraction during normal heat cycles, and longer header tabs add resistance against tank-to-header leaks. A transmission oil cooler is included. This radiator fits a wide range of Mack and Volvo applications, including the Mack CHN, CHU, GU4, GU5, GU7, and GU8 as well as the Volvo VAH and VHD, covering model years from 2006 through 2019 depending on engine configuration. It is a down-flow design with a top-left inlet and bottom-right outlet, each measuring 2.52 inches in diameter. Order Reach Cooling 42-10406 for the correct fit your Mack or Volvo demands.
