Information

The expansion tank is a part of the cooling system of the car. It is the small pot that adds water. It is generally round, and there are other shapes. Depending on the model, its main function is that when the temperature of the coolant rises, the water level will rise. The coolant that cannot hold in the (radiator) will return to the expansion tank to prevent the pressure of the water tank from being too high, and on the contrary, it will replenish the water level of the water tank. In addition, it is also used as a place to check the coolant level, and there is a scale on it.

When the temperature of the cooling system of the car increases, the coolant will expand. If there is no expansion tank, the pressure of the cooling system will increase, and the coolant will be sprayed from the gap or crush the cooling system parts, making the cooling system malfunction. The expansion tank is used to store the coolant that expands as the temperature rises. It can also be used to add coolant, and if the coolant is low, it can be added from the expansion tank.
