Caterpillar, International Radiator - Northern Radiator 238822, Active Radiator Supply Company 640123, LT9405, Reach Cooling 42-10992

Keep your Caterpillar CT660 or International 5900i running cool with the Reach Cooling 42-10992, an aftermarket radiator engineered to meet or exceed OE specifications. This unit is a direct replacement for OEM 1103750 and cross-references Northern Radiator 238822, Active Radiator Supply Company 640123, and LT9405, making it straightforward to confirm the right fit before you order. Applications include the 2011-2014 Caterpillar CT660 in 10.5L, 12.4L, and 15.2L configurations, as well as the 2015 International 5900i in 12.4L and 14.9L. The aluminum core uses B-type tubes with central reinforcement for greater pressure tolerance and dramatically reduced tube failure rates. Deep extrusion headers create a stronger tube-to-header joint that resists vibration and thermal expansion, virtually eliminating those joints as a leak source. Folded fin edges add stability and improve heat disbursement, while thermal expansion cuts allow the core to breathe through normal heat cycles for extended service life. The down-flow design features a top-left inlet and bottom-right outlet, each 2.52 in (64 mm), and includes an integrated transmission oil cooler with fittings spaced 11.5 in apart. Core dimensions are 38.5 in tall, 40.44 in wide, and 2.05 in thick. If OEM 1103750 is what you need replaced, this is the correct, direct-fit aftermarket solution.
