TFR0034 is a downflow radiator for the Freightliner Columbia, model years 2004 to 2007.
The core measures 41.8125" high by 31.5" wide, 2" deep. It has a 2.5" inlet at the right / 5-3/4" and a 2.5" outlet at the left / 5-3/4". There is no integral oil cooler and no filler neck.
It replaces 44 OEM and aftermarket numbers, among them FRE24, LT1044, 1708379PAC. 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.
