TMR0001 is a radiator for the Mack LEU, model years 2010 to 2014.
The core measures 31.375" high by 17.0625" wide, 2.25" deep. It has a 1.5" inlet at the top left and a 1.5" outlet at the top right. There is no integral oil cooler and no filler neck.
It replaces 16 OEM and aftermarket numbers, among them MAC38, 21349649, 3E127170000. 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.
