TIR0017 is a crossflow radiator for International trucks, model years 2007 to 2017.
The core measures 40.1875" high by 27.375" wide, 2.25" deep. It has a 2.5" inlet at the bottom right and a 2.5" outlet at the top left. There is no integral oil cooler and no filler neck.
It replaces 70 OEM and aftermarket numbers, among them NAV19, 1S180129, 1S180130. 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.
