TKC0005 is a charge air cooler for Kenworth trucks, model years 1989 to 2005.
The core measures 28.25" high by 27.6875" wide, 2.25" deep. It has a 4" inlet and a 4" outlet.
It replaces 65 OEM and aftermarket numbers, among them CAC110B, 4860900003, 4860900004. 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.
