BMW X3 Replacement Expansion Tank Information


Comfort-optimized vehicles like the plush BMW X3 are designed to be handled with care and always serviced and maintained. Your car or truck absolutely demands the best premium replacement parts that are available. When you drive an automobile designed for maximum performance it needs the best quality auto parts. BMW X3 Expansion Tanks provide a place for your coolant to expand as temperatures rise, preventing your car's radiator from leaking or boiling over, or coolant from overflowing from your cooling system. Your car's Expansion Tank is an important component of the car's cooling system, which stops the engine from overheating and allows a car to maintain the right temperature. Your Expansion Tank retains the excess fluid in the cooling system that spilled out of the cooling system and sends it back when it cools off. Without the Expansion Tank on a vehicle, the antifreeze that is discharged by the pressure would most likely leak out of the car and can be harmful for the environment. You should test the level of antifreeze in the vehicle's Expansion Tank frequently since drops in a car's antifreeze level indicate that there is a leak in the car's cooling system.
