TFR0058 is a downflow radiator for the Freightliner Business Class M2-106, model years 2004 to 2007.
The core measures 31.625" high by 25.25" wide, 2" deep. It has a 2" inlet at the right and a 2" outlet at the left. There is no integral oil cooler and no filler neck.
It replaces 65 OEM and aftermarket numbers, among them FRE40, 5772A, B9423. 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.
