SKU: 437220S
437220S is a Mack radiator with solder-on tanks and a 32.375 x 22.375 x 1.875 inch core. It has a 2 inch inlet and a 2 inch outlet. This bus and truck radiator interchanges with 8 other part numbers, which narrows the match when replacing an existing Mack unit by its cross-reference number.
Use only green or yellow antifreeze in this radiator. Red antifreeze, or any extended-life (OAT) coolant, voids its warranty. Why coolant type matters
