Mack, Volvo Radiator - Northern Radiator 238805, Active Radiator Supply Company 7300-15, Serck FLA000458, Reach Cooling 42-10995

When your Mack or Volvo truck needs a reliable cooling system repair, Reach Cooling 42-10995 delivers an aftermarket radiator built to meet or exceed OEM standards. This unit directly replaces OEM 21000188 and cross-references Northern Radiator 238805, Active Radiator Supply Company 7300-15, Serck FLA000458, and LT9373, making it straightforward to confirm you have the right part before it hits the shop floor. Fitment covers 2008-2016 Mack CHU 12.8L, GU7 10.8L and 12.8L, and GU8 10.8L and 12.8L, along with 2013-2016 Mack GU4 and GU5 8.9L, 2014-2016 Volvo VAH 10.8L and 12.8L, and 2015-2016 Volvo VHD 10.8L and 12.8L. The aluminum core uses B-type tubes with central reinforcement to handle pressure cycles, while deep extrusion headers and longer header tabs resist the tube-to-header and tank-to-header leaks that sideline trucks in demanding conditions. Thermal expansion cuts allow the core to breathe through normal heat cycles, reducing long-term failure rates, and folded fin edges add stability and improve heat disbursement. A transmission oil cooler is included, and multi-fit attachments allow the radiator to cover multiple applications without sacrificing OE fit. If you are sourcing by cross-reference or troubleshooting an overheating complaint on a Mack GU or Volvo VHD, this is the confirmed direct replacement.
