International Radiator - Northern Radiator 238742, Spectra Premium 2001-3542, Active Radiator Supply Company 640116, Reach Cooling 42-10531

The Reach Cooling 42-10531 is an aftermarket radiator built to keep International medium-duty trucks running at the right temperature mile after mile. It directly replaces Northern Radiator 238742, Active Radiator Supply Company 640116, Spectra Premium 2001-3542, 1-800-Radiator 2401247, Serck FLA002299, and NAPA NR4210531, making it easy to confirm you are ordering the right part. The aluminum two-row core features B-type tubes with central reinforcement for superior pressure tolerance and dramatically reduced tube failure rates. Deep extrusion headers create a stronger tube-to-header joint that stands up to vibration and thermal cycling, while folded fin edges improve stability and heat disbursement. Thermal expansion cuts allow the core to breathe during normal heat cycles, and longer header tabs increase pressure resistance to prevent tank-to-header leaks. Multi-fit attachments let this single radiator cover a broad range of applications without compromising OE fit. This unit fits International 7300, 7400, 7500, 7600, WorkStar 7300, WorkStar 7400, and WorkStar 7600 trucks spanning model years 2008 through 2016 across multiple engine displacements. If you are replacing a failed or leaking radiator on any of these International models, the 42-10531 delivers a direct, correct-fit replacement that meets or exceeds original equipment specifications.
