Once it exceeds that level, the coolant passes the radiator cap seal and spills into the overflow tube, and then flows into the coolant overflow tank. The radiator cap is designed to contain a certain pressure. The vapor flows back to the radiator, exchanges heat with the air in the radiator, and cools, returning to liquid form. The system finds a way to release the excess tension from the radiator.

Why Is My Coolant Reservoir Boiling: How To Fix? This volume expansion also increases the radiator’s pressure and the cooling system. When the coolant liquid absorbs heat from the engine, it expands, increasing volume. The coolant overflow tank is a device in the car cooling system that stores excess overflowing coolant liquid. The friction between engine parts also constitutes substantial heat that has to be removed, so the engine doesn’t overheat. Heat is also a product of that combustion reaction in the engine. The car engine burns fuel to produce energy that powers the vehicle. Conclusion How The Radiator Coolant Overflow Tank Works.In this article, we’ll reveal its function and how it works. Most car owners may not know how important it is in their vehicles. The coolant circulates around the engine and absorbs the engine’s heat, thereby cooling the car engine.

It is one of the important components in the car’s cooling system that ensures the engine remains at optimum temperatures at all times. The liquid cools in the tank and returns to the radiator. The radiator coolant overflow tank stores excess coolant that spills from the radiator. Thus, why components such as the coolant overflow tank are important. If the temperature exceeds this level, the engine overheats and will get damaged if left unchecked. The friction raises the temperature in the engine compartment to 195 to 220 degrees Fahrenheit. The car engine consists of several components which generate friction as they rub against each other.
