TFC0026 is a charge air cooler for the Freightliner Cascadia, model years 2017 to 2020.
The core measures 36.5" high by 26.5" wide, 2" deep. It has a 4" inlet and a 4" outlet.
It replaces 14 OEM and aftermarket numbers, among them CAC534, 80534FG, 1030486. 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.
