TPR0023 is a downflow radiator for the Peterbilt 379, model years 2004 to 2007.
The core measures 41.375" high by 34.375" wide, 2.25" deep. It has a 2.5" inlet at the l and a 3" outlet at the l. There is no integral oil cooler and no filler neck.
It replaces 3 OEM and aftermarket numbers, among them 770052, 770052BT, 0706657A071. 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.
