Mack Radiator - Mack MF5590M, Northern Radiator SCSI238663, Active Radiator Supply Company 800077, Reach Cooling 42-10397

When your 2006-2007 Mack CXP needs a new radiator, the Reach Cooling 42-10397 is the aftermarket direct replacement built to meet or exceed original equipment specifications. This downflow aluminum-core radiator with PA66-GF30 tanks crosses directly to Mack MF5590M, Northern Radiator 238663, Active Radiator Supply Company 800077PTXWF, 1-800-Radiator 2401141, Serck FLA000443, and NAPA NR4210397, covering the full 2006-2007 Mack CXP lineup including the 2007 Mack CXP Vision in both 10.8L and 12.8L configurations. The design incorporates B-type tubes with central reinforcement for superior pressure tolerance, deep extrusion headers that resist vibration and thermal expansion at the tube-to-header joint, folded fin edges for improved heat disbursement, and thermal expansion cuts that extend core life through normal heat cycles. A transmission oil cooler is integrated with fittings spaced 10 inches apart, making this a comprehensive cooling system solution. Longer header tabs reduce the risk of tank-to-header leaks, and multi-fit attachments allow broad vehicle coverage without sacrificing OE fit. If you are sourcing by Mack MF5590M or any of the listed interchange numbers, this Reach Cooling unit is the confirmed replacement for your Mack CXP.
