SKU: 437363S
The 437363S is a solder on tank radiator that fits 1999-2004 Isuzu NPR, NPR-HD and NQR trucks. It has a 23.25 x 21.625 x 1.5 in core (height x width x depth), 1 5/8 in inlet and outlet connections, and a 14 3/8 in oil cooler on the grille side. Side brackets are not included, so the OE brackets must be reused. It interchanges with 66 other part numbers.
Use only green or yellow antifreeze in this radiator. Red antifreeze, or any extended-life (OAT) coolant, voids its warranty. Why coolant type matters
