TFC0019 is a charge air cooler for Freightliner trucks, model years 1993 to 2002.
The core measures 36.875" high by 21.25" wide, 2.25" deep. It has a 4" inlet and a 4" outlet.
It replaces 47 OEM and aftermarket numbers, among them CAC107, 1B3017, 4858000001. 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.
