SKU: 437443S
The 437443S is a Peterbilt radiator with a solder on tank and a 36 x 36.75 x 1.875 in core (height x width x depth). It has 2 1/2-inch inlet and outlet connections and interchanges with 40 other part numbers. To confirm the match, compare the core height, width and depth, the connection sizes and the tank construction of the unit being replaced.
Use only green or yellow antifreeze in this radiator. Red antifreeze, or any extended-life (OAT) coolant, voids its warranty. Why coolant type matters
