TIR0054 is a crossflow radiator for the International 5000.
The core measures 46.375" high by 31.5" 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 25 OEM and aftermarket numbers, among them 640010, 640010ST, 6410. 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.
