Western Star Radiator - Western Star WSRP13120B2, Active Radiator Supply Company 8000-96, 1-800-Radiator 2401048, Reach Cooling 42-10471

When your Western Star needs a new radiator, Reach Cooling 42-10471 is the aftermarket direct replacement built to meet or exceed OE specifications. This unit replaces Western Star WSRP13120B2 and cross-references Active Radiator Supply Company 800096, 1-800-Radiator 2401048, Serck FLA001506, NAPA NR4210471, and Cancore Industries WES15, making it straightforward to confirm you have the right part. The aluminum core features B-type tubes with central reinforcement for greater pressure tolerance, deep extrusion headers that resist vibration and thermal stress at the tube-to-header joint, and thermal expansion cuts that allow the core to breathe through normal heat cycles, all working together to reduce the most common failure points in heavy-duty radiators. Longer header tabs add an extra margin of pressure resistance at the tank-to-header seal, and folded fin edges improve heat disbursement and core stability. Multi-fit attachments allow this single radiator to cover multiple Western Star applications without compromising OE fit. This radiator fits Western Star 4800SB, 4900EX, 4900FA, and 4900SA models spanning 2008 through 2015 across a wide range of engine displacements, including Detroit Diesel DD15 configurations. If you are sourcing by OEM number WSRP13120B2 or by any of the listed interchanges, Reach Cooling 42-10471 is the confirmed aftermarket replacement for your Western Star.
