Chevrolet, GMC Radiator - Active Radiator Supply Company 5800-03, Superior Cooling Systems 239322, LT9140, Reach Cooling 42-11000

The Reach Cooling 42-11000 is an aftermarket radiator built as a direct replacement for 1995-2002 Chevrolet and GMC medium-duty trucks, cross-referencing OEM part 3096049, Active Radiator Supply Company 5800-03, Superior Cooling Systems 239322, and LT9140. Designed to fit the Chevrolet and GMC B7, C60 Kodiak, C6000 Topkick, C6500 Kodiak, C6500 Topkick, C70 Kodiak, C7000 Topkick, C7500 Kodiak, and C7500 Topkick across 6.0L, 6.5L, 6.6L, 7.0L, 7.2L, 7.4L, and 8.1L engine applications, this cross-flow radiator features an aluminum core with B-type tubes that include central reinforcement for greater pressure tolerance and a significantly reduced risk of tube failure. Deep extrusion headers create a stronger tube-to-header joint that resists vibration and thermal expansion, while thermal expansion cuts allow the core to breathe through normal heat cycles for extended service life. Folded fin edges add stability and improve heat disbursement, and longer header tabs reduce the potential for tank-to-header leaks. Multi-fit attachments allow one unit to cover multiple applications without sacrificing OE fit. A transmission oil cooler is included; radiator cap and frame are not. Built to meet or exceed original equipment specifications, this radiator delivers a correct, drop-in fit for your Kodiak or Topkick.
