TKC0017 is a charge air cooler for Kenworth trucks.
The core measures 24.5" high by 20.25" wide, 2.375" deep. It has a 0" inlet and a 0" outlet. There is no integral oil cooler and no filler neck.
It replaces 29 OEM and aftermarket numbers, among them KEN16507, KEN16507N, 1110A. 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.
