TIR0001 is a crossflow radiator for the International 4900, model years 1993 to 1996.
The core measures 35.625" high by 29" 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 34 OEM and aftermarket numbers, among them INT72, 11944, 11C8804. 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.
