Research on Expansion Tank for BMW 323i
How does the BMW 323i Expansion Tank function?
When your BMW 323i Engine is heating up, the coolant stored inside begins to expand. In case you don't have the BMW 323i Expansion Tank, then the coolant will flow out of the overflow tube and be lost from the cooling system onto the driveway or the road as you drive. However, the coolant will normally flow into the BMW 323i Expansion Tank.
There is a vacuum that is usually formed in the cooling system when your vehicle's engine is cooling; this vacuum usually causes some of the coolant in the expansion tube to be sucked back into the system. Since a cooling system without an expansion tank is basically a closed system, then the coolant is usually able to flow between the system and the expansion tank as it starts to expand and contract. With this system in place, no coolant can be lost when the system is functioning properly. Yet another function of your BMW 323i Expansion Tank is to remove air bubbles that are formed in the cooling system. When there is coolant in your cooling system that has fewer bubbles, the cooling system tends to work more efficiently than coolant with air bubbles; this is because it is able to absorb heat much faster . The main advantage of your BMW 323i Expansion Tank is that while the level of the coolant contained in it rises and falls, your BMW 323i radiator will always be full. Older cars can also be fitted with expansion tanks, and this can be done by simply mounting the tank close to the radiator, and connecting an overflow tube, and then replacing the radiator cap.
BMW 323i Expansion Tank Cost
A BMW 323i Expansion Tank replacement costs between $75 and $139. The labor costs are estimated between $23 and $36 while the parts are priced between $45 and $105. It's important that you get a personalized quote that is based on the model, make, a year as well as the location of the vehicle in question.
