TFC0015 is a charge air cooler for Freightliner, Sterling, Western Star trucks, model years 2008 to 2018.
The core measures 34.75" high by 26" wide, 2.5" deep. It has a 4" inlet and a 4" outlet.
It replaces 98 OEM and aftermarket numbers, among them CAC399, 80399FG, 0131242000. 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.
