TKC0009 is a charge air cooler for the Kenworth T300, T400, model years 1997 to 2003.
The core measures 0" high by 0" wide, 0" deep. It has a 0" inlet and a 0" outlet.
It replaces 40 OEM and aftermarket numbers, among them CAC112D, 486230002, 85103373. 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.
