TKR0006 is a downflow radiator for Kenworth trucks, model years 2011 to 2014.
The core measures 25.75" high by 39.4375" wide, 2" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the right / bottom. There is no integral oil cooler and no filler neck.
It replaces 39 OEM and aftermarket numbers, among them KEN30, 110120G, F316164110120. Searching any one of them will find this part.
On radiators the inlet and outlet positions, and whether the unit carries an oil cooler, decide interchangeability more often than core size does. Two radiators with identical cores are frequently not interchangeable.
