TFR0016 is a crossflow radiator for the Freightliner Argosy, FL112, model years 1997 to 2007.
The core measures 47" high by 27.125" wide, 2" 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 136 OEM and aftermarket numbers, among them FRE16, 0517261001, 1SA00213. 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.
