Research on Expansion Tank for Mini Cooper

The expansion tank collects expanding coolant heated in the engine and recycles it back to the coolant system once the heat is dissipated. It serves as a reservoir for engine coolant that has reached boiling point and can potentially rise out of the radiator. The expansion tank works in conjunction with the spring built cap that is thermally activated. As temperature and pressure rises the coolant gets to the boiling point, the cap spring gets activated and allows the heated liquid to flow to the overflow tank. This system works under pressure which increases the effectiveness of the system. Previously engines were cooled by large mechanical fans. However, most modern vehicles make use of both an electric fan and a closed cooling system.

Mini Cooper Expansion Tank Glitches

Your expansion tank is an integral part of your engine's cooling system. When it has issues it causes problems with your engine due to overheating. You will know that your expansion tank has a problem when you are constantly low on coolant. This can be caused by a leaking expansion tank, though they may be small leaks that are not easily noticeable. Cracks may also cause the coolant to eventually evaporate. Another very obvious symptom of a malfunctioning expansion tank is an overheating engine. If the tank has a problem like a malfunctioning Mini Cooper expansion tank cap that prevents it from properly storing coolant or from pressurizing the system it may cause the engine to overheat. Leaking may result to a Mini Cooper expansion tank empty while overheating of the engine may cause a Mini Cooper expansion tank boiling.

Replacing Your Expansion Tank

If you are having problems with your cooling system, get a professional to diagnose it. The coolant expansion tank may not be a major component, but when it has issues it can result to engine damage because of excessive heating. A Mini Cooper expansion tank replacement can cost you an average of between $114 to $160, with labor ranging from $70 to $89 and parts are priced from $44 to $71. You can also replace your Mini Cooper coolant reservoir cap if damaged or malfunctioning; this is a critical component because it maintains the system at a certain pressure and prevents coolant from boiling over.

How do I drain my coolant tank?

You can easily drain your coolant tank by first raising the front of your vehicle on jacks. Place a pan under the radiator to collect the coolant, and then remove the radiator cap. If it has a pressure cap instead you can remove it, as well as the drain cock to drain the radiator.

Remember your cooling system should function efficiently to prevent your vehicle from overheating and to keep the engine running optimally. You can always clean your coolant tank to remove coolant that is no longer functional and replace with fresh coolant. Check also that the expansion tank is functioning properly. For all automobile parts and accessories you can get the best deals at PartsGeek.com.

I had to replace a friends expansion tank on her 2003 Mini Cooper S. The seam along the center of the tank had cracked and was leaking coolant. This part supplied from Parts Geek was an exact replacement and looked factory stock. It was a simple fix and took about 15 minutes to replace. Thanks Parts Geek! - Perfect fit
