TIR0015 is a downflow radiator for International trucks, model years 2003 to 2010.
The core measures 33.5" high by 28" wide, 2.25" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the right / bottom. There is no integral oil cooler and no filler neck.
It replaces 111 OEM and aftermarket numbers, among them NAV15, 1N180029G, 1N180072G. 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.
