The radiator cap has multiple crucial functions within a vehicle's cooling system.
The radiator cap is designed to perform the following key functions, according to the provided reference:
- Seal the radiator: The cap seals the top of the radiator filler neck. This prevents coolant loss, which is essential for maintaining proper engine temperature.
- Pressurize the Cooling System: The cap pressurizes the cooling system.
- Raise the Boiling Point: By pressurizing the system, the radiator cap raises the boiling point of the coolant. This prevents the coolant from boiling over, especially under high-temperature conditions.
The material used to manufacture radiator caps can be either metal or plastic, depending on the vehicle manufacturer's specifications.
In summary, the radiator cap is more than just a lid; it's a vital component that ensures efficient and reliable engine cooling by preventing leaks and maintaining optimal pressure within the system.
