TSC0002 is a charge air cooler for Sterling trucks, model years 1999 to 2004.
The core measures 0" high by 0" wide, 0" deep. It has a 0" inlet and a 0" outlet.
It replaces 47 OEM and aftermarket numbers, among them CAC126B, 011288L, 016444L. 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.
