TKR0010 is a downflow radiator for the Kenworth T800, model years 2003 to 2007.
The core measures 37.75" high by 24" wide, 2.25" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the left. There is no integral oil cooler and no filler neck.
It replaces 20 OEM and aftermarket numbers, among them 650008, 650008ST, 6508. 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.
