When your 2008-2010 Hino 238, 258, 258ALP, 258LP, 268, 268A, or 338 needs a new radiator, this aftermarket unit from Reach Cooling is built to match or exceed original equipment specifications so you can get back on the road with confidence. It directly replaces Hino 5225R and cross-references Northern Radiator 238815, Active Radiator Supply Company 5900-25, NAPA NR4210645, OSC HD9352, and Lynol Cooling Systems 2216-005, making it straightforward to verify the correct fit against your existing part number. The aluminum core features B-type tubes with central reinforcement for greater pressure tolerance, deep extrusion headers for a stronger tube-to-header joint, and folded fin edges for improved stability and heat disbursement. Thermal expansion cuts are incorporated throughout to allow the core to breathe through normal heat cycles, reducing long-term failure rates. A transmission oil cooler is included, and multi-fit attachments provide broad vehicle coverage without compromising OE-quality fitment. The inlet and outlet are both 2.17 inches in diameter, positioned top right and bottom left respectively, in a downflow configuration. If you are sourcing this radiator by Hino 5225R or any of the listed interchange numbers, this Reach Cooling 42-10645 is the confirmed direct replacement for 7.7L Hino medium-duty applications from 2008 through 2010.
