TMC0006 is a charge air cooler for Mack trucks, model years 1995 to 2008.
The core measures 37.625" high by 28.5" wide, 2.625" deep. It has a 3.5" inlet and a 3.5" outlet.
It replaces 58 OEM and aftermarket numbers, among them CAC119E, 25174858, 317D543M. 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.
