This radiator cap fits Kenworth and Peterbilt cooling systems, replacing the factory cap on multiple Kenworth applications and universal Peterbilt setups. It is a PAI-made replacement sold individually, one per pack. The cap seals the filler neck and holds the coolant system's pressure, opening its valve to vent excess pressure and prevent overheating or coolant loss.
