TFR0014 is a downflow radiator for the Freightliner Business Class M2-106, model years 2003 to 2007.
The core measures 34" high by 26.875" wide, 2" deep. It has a 2" inlet at the left and a 2" outlet at the right. The unit carries an oil cooler at the bottom and no filler neck.
It replaces 37 OEM and aftermarket numbers, among them FRE30, BHTD5968, BHTF1578. 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.
