The Function of a Radiator Cap
The radiator cap is a small but essential part of your car’s cooling system. Here’s a breakdown of its key functions:
- Maintains Pressure
The radiator cap keeps the cooling system pressurized, which raises the boiling point of the coolant and prevents overheating. - Controls Coolant Flow
It allows coolant to flow into the overflow tank when the pressure gets too high and pulls it back into the radiator when the pressure drops. - Prevents Leaks
The cap seals the radiator tightly, preventing coolant from leaking and ensuring the system remains full and efficient. - Regulates Temperature
By maintaining the correct pressure, the cap helps control the engine’s temperature, ensuring it doesn’t get too hot. - Protects the Cooling System
The radiator cap helps prevent damage to the radiator, hoses, and other cooling system components by ensuring the system operates at the right pressure.
In short, the radiator cap is essential for keeping your car’s engine cool and running smoothly!
