Kenworth Radiator - LT9610, OEM F3160881101120, Reach Cooling 42-11021

When your Kenworth T660, T880, or W900 needs a new radiator, Reach Cooling 42-11021 delivers an aftermarket replacement built to meet or exceed OEM specifications - and it ships with the frame included. This down-flow aluminum-core radiator replaces LT9610 and OEM SGEF-052 WITH FRAME, the two primary interchange references mechanics and fleet buyers search when sourcing this unit. Coverage spans Kenworth T660 models from 2008 through 2016, T880 models from 2011 through 2016, and W900 models from 2008 through 2016, across engine displacements ranging from 8.8L up to 15.8L. Reach Cooling engineers these radiators with B-type tubes featuring central reinforcement for greater pressure tolerance, deep extrusion headers that resist vibration and thermal expansion at the tube-to-header joint, folded fin edges for improved stability and heat disbursement, and thermal expansion cuts that allow the core to breathe through normal heat cycles - all of which add up to reduced leak rates and longer service life. The aluminum core is paired with PA66-GF30 tanks, with the inlet positioned top left and the outlet bottom right, both at 2.52 inches. Frame included means no extra fabrication on the install. For Kenworth T660, T880, and W900 applications where a correct-fitting, frame-complete radiator matters, Reach Cooling 42-11021 is the direct replacement.
