TPC0003 is a charge air cooler for the Peterbilt 330, model years 2000 to 2003.
The core measures 34.875" high by 16.875" wide, 2.25" deep. It has a 4" inlet and a 4" outlet.
It replaces 28 OEM and aftermarket numbers, among them CAC112P, 0518997, 4862700004. 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.
