This cross-flow aluminum-core radiator replaces OEM KEN15 and cross-references Northern Radiator 238807, Active Radiator Supply Company 6500-15, and LT9216, making it straightforward to confirm you have the right part before it arrives. Fitment covers Kenworth C500 models from 2008 through 2016 across multiple engine displacements, as well as Kenworth T800 models from 2008 through 2012. The 2-row aluminum core measures 44 inches tall by 40.47 inches wide by 2.05 inches thick, with PA66-GF30 tanks, a center-left inlet and bottom-right outlet each at 2.52 inches in diameter. Construction highlights include B-type tubes with central reinforcement for greater pressure tolerance, a deep extrusion header that resists vibration and thermal expansion at the tube-to-header joint, folded fin edges for improved stability and heat disbursement, and thermal expansion cuts that allow the core to breathe through normal heat cycles and extend service life.
