TIC0031 is a crossflow charge air cooler for International trucks, model year 2000.
The core measures 23.5" high by 30" wide, 1.5" deep. It has a 0" inlet and a 0" outlet. There is no integral oil cooler and no filler neck.
It replaces 82 OEM and aftermarket numbers, among them NAV16404, NAV16404N, NAV16404R. Searching any one of them will find this part.
On charge air coolers the inlet and outlet positions and the boot diameters matter as much as the core. A cooler that fits the opening but presents its connections on the wrong side will not plumb up.
