Mack Radiator - Northern Radiator SCSI238633, Spectra Premium 2001-3007, Active Radiator Supply Company 730008PT, Reach Cooling 42-10395

When your 2000-2005 Mack CX needs a radiator, the Reach Cooling 42-10395 delivers an aftermarket replacement built to meet or exceed the original equipment specifications your truck was designed around. This unit directly replaces Northern Radiator 238633, Active Radiator Supply Company 7300-08, Spectra Premium 2001-3007, 1-800-Radiator 2400107, Serck FLA000419, and NAPA 20013007, making it one of the most broadly cross-referenced options available for the Mack CX Vision, CX612, and CX613. The aluminum core runs three rows deep at 36 inches tall and 27.87 inches wide with a 48 mm thickness, paired with durable plastic PA66-GF30 tanks. The top-right inlet and bottom-left outlet both measure 2 inches in diameter, matching the factory plumbing without modification. Construction features include deep extrusion headers that resist vibration and thermal fatigue at the tube-to-header joint, folded fin edges for added stability and heat dissipation, and thermal expansion cuts that let the core breathe through normal heat cycles. Longer header tabs reduce the risk of tank-to-header leaks, and the B-type reinforced tubes are engineered to handle pressure more reliably than standard designs. For Mack CX fleet buyers and owner-operators looking for a confirmed fit and proven construction, this is the direct replacement to reach for.
