When your Peterbilt 382 needs a reliable cooling solution, the Reach Cooling 42-10403 aftermarket radiator is a direct replacement built to meet or exceed original equipment specifications. This unit replaces Peterbilt 1102310B and cross-references Northern Radiator 238718, Active Radiator Supply Company 7700-38, Spectra Premium 2001-3815, 1-800-Radiator 2401045, and Serck FLA000530, making it easy to confirm you have the right part before it ships. Designed for the 2011-2017 Peterbilt 382 8.9L, it features an aluminum core with plastic tanks in a two-row, down-flow configuration. Reach Cooling's B-type tubes include central reinforcement for greater pressure tolerance, while the deep extrusion header creates a stronger tube-to-header joint that stands up to vibration and thermal cycling. Folded fin edges improve stability and heat dissipation, and thermal expansion cuts allow the core to breathe through normal heat cycles, extending service life and reducing failure rates. Longer header tabs add an extra layer of protection against tank-to-header leaks. Whether you're sourcing by Peterbilt 1102310B or by any of the listed interchange numbers, Reach Cooling 42-10403 delivers the correct fit and dependable performance your Peterbilt 382 demands.
