TPR0009 is a crossflow radiator for the Peterbilt 330, 335, 340, model years 2003 to 2007.
The core measures 34.625" high by 16" wide, 2.25" deep. It has a 2.25" inlet at the left and a 2.25" outlet at the right. There is no integral oil cooler and no filler neck.
It replaces 80 OEM and aftermarket numbers, among them PET05, 3E0099930000, 3E0106730000. 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.
