Kenworth Radiator - Kenworth GOMX3921, Northern Radiator 238797, Active Radiator Supply Company 650004ST, Reach Cooling 42-10394

When your Kenworth T300 needs a new radiator, Reach Cooling 42-10394 is the aftermarket replacement built to meet or exceed original equipment specifications. This cross-flow aluminum-core radiator directly replaces Kenworth 230051004, the primary OEM interchange, along with Northern Radiator 238797, Active Radiator Supply Company 650004, 1-800-Radiator 2401219, Serck FLX000305, and NAPA NR4210394. Fitment covers Kenworth T300 trucks from 1995 through 2003, spanning a wide range of engine displacements including 5.9L, 7.2L, 8.3L, 10.8L, and 14.0L configurations. The radiator features B-type tubes with central reinforcement for superior pressure tolerance, deep-extrusion headers that resist vibration and thermal stress to virtually eliminate tube-to-header leaks, and fin edges folded for added stability and heat disbursement. Thermal expansion cuts in the core allow for natural expansion and contraction through heat cycles, extending service life and reducing failure rates. Multi-fit attachments let a single unit cover multiple T300 applications without compromising OE-quality fit. The PA66-GF30 plastic tanks are paired with a two-row aluminum core measuring approximately 36.38 inches tall and 25.12 inches wide. No transmission oil cooler, engine oil cooler, radiator cap, frame, or filler neck is included. If you are sourcing by OEM number or cross-reference, Reach Cooling 42-10394 delivers the correct fit and confident cooling performance your T300 demands.
