TFC0018 is a charge air cooler for Freightliner, Sterling trucks, model years 1997 to 2011.
The core measures 0" high by 0" wide, 0" deep. It has a 0" inlet and a 0" outlet.
It replaces 172 OEM and aftermarket numbers, among them CAC107C, 0122901000, 0122951000. 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.
