TPR0029 is a downflow radiator for Peterbilt trucks.
The core measures 33" high by 38.375" wide, 2.125" deep. It has a 2" inlet at the dual and a 4" outlet at the right. The unit carries no integral oil cooler and a center filler neck.
It replaces 3 OEM and aftermarket numbers, among them 770058, 770058BT, 0704568M. 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.
