THC0003 is a charge air cooler for Hino trucks, model years 2008 to 2010.
The core measures 23.25" high by 17.375" wide, 2.5" deep. It has a 3.25" inlet and a 3.25" outlet.
It replaces 3 OEM and aftermarket numbers, among them CAC405, 17940E0330, 8647N. 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.
