BMW Z3 Replacement Expansion Tank Information


For some drivers, traveling off the beaten path is sometimes needed, and if this is true for you a BMW Z3 is the only way to go. Bestselling carmakers know the vital importance of satisfying performance. If you purchased your high-performance car for its awesome engine power and performance, keep up that decision with first rate replacement parts and accessories. Your BMW Z3 Expansion Tank keeps the antifreeze and water of the radiator that was forced out of the cooling system and sends it back once it has cooled off. The Expansion Tank is a vessel which allows any coolant and air bubbles inside your coolant system to expand due to a rise in temperature. An Expansion Tank permits the coolant and air in the radiator to expand with the rising temperature and increasing pressure. Without the Expansion Tank on a vehicle, the antifreeze that is released by the pressure would likely leak out of the car which can be harmful for the planet. Expansion Tanks provide room for your cooling fluid to expand as it is heated, stopping your vehicle's radiator from bursting or boiling over, or cooling fluid from spilling out of the car's cooling system.
