TKR0003 is a crossflow radiator for the Kenworth T2000, T800, W900, model years 1997 to 2007.
The core measures 38" high by 33.25" wide, 2.25" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the right. There is no integral oil cooler and no filler neck.
It replaces 69 OEM and aftermarket numbers, among them KEN05, 4870180007, 4870810009. 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.
