TPR0002 is a downflow radiator for Peterbilt trucks, model years 1995 to 2007.
The core measures 33.5" high by 27.4375" wide, 2.25" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the left. There is no integral oil cooler and no filler neck.
It replaces 27 OEM and aftermarket numbers, among them 0706210, 0706657A008, 0706973. 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.
