TPR0004 is a downflow radiator for Peterbilt trucks, model years 2008 to 2018.
The core measures 42.875" high by 39.4375" wide, 2" deep. It has a 2.5" inlet at the left and a 2.5" outlet at the right / bottom. There is no integral oil cooler and no filler neck.
It replaces 78 OEM and aftermarket numbers, among them PET19, 5767A, F3160851101310. 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.
