Sterling Truck, Freightliner Radiator - Freightliner BHTD4734, Northern Radiator SC238604, Spectra Premium 2001-1731, Reach Cooling 42-10364

The Reach Cooling 42-10364 is an aftermarket radiator built as a direct replacement for Freightliner and Sterling Truck medium-duty applications. It cross-references Freightliner 0437242S, Northern Radiator 238604, Active Radiator Supply Company 800031, Spectra Premium 20011731, 1-800-Radiator 2400088, and Serck FLA000274, making it straightforward to confirm the right fit before you order. The aluminum core with plastic tanks flows coolant efficiently, and construction features include B-type tubes with central reinforcement for greater pressure tolerance, deep extrusion headers that resist vibration and thermal expansion at the tube-to-header joint, and folded fin edges for added stability and heat dissipation. A transmission oil cooler is integrated into the 18-inch bottom tank. This radiator fits Freightliner B2, FS65, M2 100, and M2 106 trucks, as well as Sterling Truck Acterra, Acterra 5500, Acterra 6500, and Acterra 7500 models across a broad range of model years and engine displacements. Whether you are working on a Freightliner M2 106 or a Sterling Acterra 7500, this unit is engineered to install correctly and deliver cooling performance that matches or exceeds the original equipment it replaces.
