TIR0047 is a downflow radiator for the International 8100.
The core measures 34.6875" high by 26.5" wide, 2.25" deep. It has a 2.5" inlet at the right and a 2.5" outlet at the left. There is no integral oil cooler and no filler neck.
It replaces 35 OEM and aftermarket numbers, among them 640002, 640002BT, 640002PT. 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.
