TMR0012 is a downflow radiator for the Mack CX Vision, model years 2000 to 2004.
The core measures 36.0625" high by 28.5" wide, 2" deep. It has a 2" inlet at the right and a 2" outlet at the left. There is no integral oil cooler and no filler neck.
It replaces 69 OEM and aftermarket numbers, among them MAC08, 1003474, 1003475. 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.
