Radiator Cap (Big) Universal

A car radiator cap is a pressure-sealing cap that sits on top of the radiator or coolant reservoir. Its primary functions include:

Pressure Regulation: It helps maintain the correct pressure within the cooling system. By creating a sealed environment, it prevents coolant from boiling over and helps raise the boiling point of the coolant.

Coolant Recovery: When the engine heats up, the coolant expands and some may escape. The radiator cap allows this excess pressure to be released, but it also allows coolant to be drawn back into the radiator as the engine cools down, maintaining proper levels.

Safety: The cap often features a safety mechanism that prevents it from being opened when the system is pressurized, reducing the risk of burns from hot coolant.

Maintenance Indicator: Some radiator caps come with indicators that can signal when the pressure is too high or if the cap needs replacement.

Overall, the radiator cap is a critical component in maintaining an efficient and safe cooling system in a vehicle.
