International Radiator - International Harvester IHC 3527218C93, Northern Radiator SCSI238516, Spectra Premium SPI20063507A, Reach Cooling 42-10580

When your International truck needs a new radiator, the Reach Cooling 42-10580 is the aftermarket direct replacement built to restore proper cooling without the guesswork. It cross-references International Harvester IHC 2004693C91 as the primary OEM interchange, and also replaces Northern Radiator SCSI238516, Active Radiator Supply Company 640059ST, Spectra Premium 2006-3507A, Serck SRM20063507, and NAPA 20063507. The copper core and brass tank construction deliver reliable heat dissipation, while the two-row downflow design matches the original configuration exactly. B-type tubes with central reinforcement provide greater pressure tolerance, deep-extrusion headers resist vibration and thermal fatigue to eliminate tube-to-header leaks, and thermal expansion cuts in the core allow for natural expansion and contraction through normal heat cycles for extended service life. A transmission oil cooler is included. This radiator fits a wide spread of International models including the 1652SC, 1955, 3000IC, 3400, 3600, 3800, 4600, 4700, 4700LP, and 4700LPX across model years spanning 1984 through 2004 and covering multiple engine displacements. If you are sourcing by the OEM number 2004693C91 or any of the listed interchanges, the Reach Cooling 42-10580 is the confirmed aftermarket replacement that drops in correctly.
