Kenworth Radiator - Kenworth CTVTM80614, Northern Radiator 239302, Spectra Premium 20012502, Reach Cooling 42-10585

When your Kenworth T2000, T800, or W900 needs a new radiator, the Reach Cooling 42-10585 is the aftermarket direct replacement built to meet or exceed original equipment specifications. This copper-core, brass-tank cross-flow radiator directly replaces Kenworth CVTM80614, making it straightforward to confirm fitment by the OEM number alone. It also cross-references Northern Radiator 239302, Active Radiator Supply Company 6500-05, Spectra Premium 2001-2502, Serck FLX000308, and NAPA NR4210585, so it covers the interchanges fleet buyers and independent shops rely on most. Reach Cooling engineers B-type tubes with central reinforcement for greater pressure tolerance, deep extrusion headers for a stronger tube-to-header joint that resists vibration and thermal fatigue, folded fin edges for improved heat disbursement, and thermal expansion cuts that allow the core to breathe through normal heat cycles - all features aimed at reducing the leak and failure modes that sideline trucks. The 5-row core measures 38.125 inches tall by 34.375 inches wide with a 2.75-inch thickness, with a top-left inlet and bottom-right outlet, each 2.5 inches in diameter. Fitment spans Kenworth T2000 models from 1997 through 2007, T800 models from 1991 through 2002, and W900 models from 2003, covering a broad range of engine displacements. If you are sourcing by Kenworth CVTM80614 or any of the listed interchanges, the Reach Cooling 42-10585 is the confirmed correct-fit replacement.
