The Dorman expansion tank is an excellent choice when it comes to replacing the worn out one on your vehicle. An expansion tank is important if you want to save up on the coolant. As the engine heats up, the coolant expands, causing it to overflow and out it goes into the pavements. But that is not so with an expansion tank as the coolant will overflow into the expansion tank. Since a cooling system equipped with an expansion tank is practically a closed system, the coolant can flow between the system and the expansion tank as it expands and contracts. In this way, there will be no coolant lost if the system is functioning correctly. Another function of the expansion tank is to get rid of the air bubbles from the cooling system. A coolant without air-bubbles will be much more efficient than coolant with air bubbles, as it absorbs heat a lot faster. The advantage of the expansion tank is that while the level of coolant contained in it increases and decreases, the radiator will always be full. The earlier cars can easily be integrated with expansion tanks, simply by mounting the tank near the radiator, connecting it to the overflow tube, and replacing the radiator cap. If your expansion tank is already inefficient, replace it with a new one. That way, it will be more practical on your side plus the chances of you damaging the environment will be decreased. The Dorman expansion tanks are guaranteed to be functioning efficiently and they are guaranteed to have a long service life.
