TSC0005 is a charge air cooler for the Sterling, Western Star 4900 SA, A/AT9500, L/LT9500, model years 2004 to 2007.
The core measures 36.875" high by 26.25" wide, 2.25" deep. It has a 4" inlet and a 4" outlet.
It replaces 181 OEM and aftermarket numbers, among them CAC107EH, 1AA00111, 1AA00111S. 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.
