TIR0009 is a crossflow radiator for International trucks, model years 1987 to 2007.
The core measures 41" high by 29.25" wide, 2.25" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the right. There is no integral oil cooler and no filler neck.
It replaces 404 OEM and aftermarket numbers, among them NAV03, 1693614C91, 1693644C91. 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.
