It seals the cooling system to maintain pressure, allowing the coolant to expand and contract without boiling over. Replace the cap if it is cracked, the rubber seal is damaged, or it fails to hold pressure, which can cause overheating or coolant loss. The same part is also used on Volvo Penta marine engines (DH10A and D16C-A). Note: The store's fuel system category is likely a misclassification; this cap is for the cooling system, not the fuel system.
