SKU: 437299
The 437299 is a bolt on tank radiator with a 6 x 11 3/4 crankbox that fits 1993-2007 Peterbilt 320 trucks. The core measures 36.5 x 29.625 x 2.25 inches (height x width x depth), with 2 1/2 inch inlet and outlet connections. The same unit without a crankbox is 437298. Fitment covers 15 Peterbilt 320 vehicle applications, and it interchanges with 14 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
