TIR0030 is a crossflow radiator for International trucks, model years 2008 to 2012.
The core measures 28.5" high by 28.5" wide, 2.25" deep. It has a 2.25" inlet at the left and a 2.5" outlet at the right. The unit carries an oil cooler at the bottom and no filler neck.
It replaces 35 OEM and aftermarket numbers, among them NAV33, 1S180144, 2593301C91. 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.
