TFR0088 is a radiator for Freightliner trucks.
The core measures 29.75" high by 25.875" wide, 1.75" deep.
It replaces 11 OEM and aftermarket numbers, among them 00010507, 0010507, 00115578. 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.
