TIR0033 is a downflow radiator for the International Prostar, model years 2009 to 2012.
The core measures 35.5" high by 39.5625" wide, 2.1875" deep. It has a 2.5" inlet at the upper left and a 2.5" outlet at the lower right. The unit carries an oil cooler at the bottom and no filler neck.
It replaces 25 OEM and aftermarket numbers, among them NAV47, 2594850C91, 3E0117490000. 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.
