TMR0010 is a downflow radiator for the Mack CH, CHU, GU Granite, model years 2008 to 2016.
The core measures 39.125" high by 34.375" wide, 2" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the right. The unit carries an oil cooler at the bottom and no filler neck.
It replaces 95 OEM and aftermarket numbers, among them MAC19, 21000184, 21000185. Searching any one of them will find this part.
On radiators the inlet and outlet positions, and whether the unit carries an oil cooler, decide interchangeability more often than core size does. Two radiators with identical cores are frequently not interchangeable.
