Reasons Behind Radiator Tank Expansion Failure In A MINI

by schearerswpadmin May 30, 2019

radiator tank expansion is a vital part of your MINI. When it begins to fail, you could be in serious trouble. You paid good money for your luxury car, and you certainly do not want to see it in disrepair due to one small, seemingly insignificant part. We understand that, and we are here to help. In order to prevent the destruction that will cost a fortune, you need to know:

  • What a radiator tank expansion does
  • The warning signs of a failing tank expansion
  • What causes expansion failure
  • What happens when the problem is not fixed
  • How you can repair it before it is too late

The Function Of A Radiator Tank Expansion

A radiator tank expansion (or RTE, for short) is a container that provides extra storage space for coolant when it expands. It can also be called an overflow tank. The expansion recycles this coolant to keep your engine functioning at optimal temperatures for a longer period of time.

Warning Signs Of Radiator Tank Expansion Failure

When the RTE begins to malfunction or fail, you may notice some of these warning signs:

  • Rust has formed in the radiator. The overflow tank usually keeps this from happening. This is one of the main functions the RTE serves. When your radiator is rusty, you should assume that your RTE may be failing.
  • The engine will overheat. Coolant does exactly what it sounds like: it keeps your engine cool. When your MINI overheats, it can damage the engine irreparably and cause your vehicle to break down on the road. It is vital to get this issue fixed without letting it run hot for extended periods.
  • Coolant levels will be low. Your coolant should be replaced or topped off according to the specific manufacturer’s instructions. Always check your driver manual for reference. If your coolant is running low before it should be, your RTE could have failed. This is because it has caused the coolant to leak.
  • Coolant is leaking. The liquid you see underneath your MINI will determine whether or not your coolant is leaking. Coolant will usually be something colorful, like blue, green, red, yellow, pink, or orange. Oil is black, and although it gives off a colorful sheen, it should not be confused with colorful coolant.
  • You will be able to smell the coolant. The scent is unmistakable. Instead of being pungent and burning like gasoline, it will have a sweet aroma.

What Causes RTE Failure?

  • The reservoir has cracked. This allows the coolant stored inside to leak out. Depending on how bad/big the crack is, you could lose a lot of coolant very quickly. This happens mostly due to age or any overheating in the past.
  • Time. Every auto part eventually needs to be replaced, including the RTE. It is just something you have to deal with if you own any vehicle.
  • The RTE is not pressurized correctly. This is what causes the engine to overheat.
  • The radiator cap is broken or not sealed properly. When this happens, the pressure it needs to keep coolant flowing is lost.

The Consequences Of Procrastination

If you notice any of these things happening while driving your MINI, and you fail to get the issue repaired, you are asking for trouble. The engine may become catastrophically damaged. Putting off service could cause your engine to break down permanently, and replacement of the engine can be extremely expensive. Your car could also actually catch on fire. Obviously, this is the worst-case scenario, but prolonged overheating can start a fire in the engine. It could and likely would seriously injure you and others if it causes you to crash.

How To Take Care Of Radiator Tank Expansion Failure

MINIs are special vehicles that require special Adding Coolant in MINI care. You can’t fix the RTE by yourself. You have to trust a professional mechanic to do these repairs. Not all auto shops are made alike, so you need to be careful where you take your MINI. A standard mechanic may not have the skill set they need to get the job done right. This is why you should trust the technicians at Schearer’s Sales and Service, Inc. Our mechanics won’t stop until they know that you are satisfied with the care you are receiving. We will assure that you will drive home safely with proper repairs.

what people say about us

Excellent & timely service – keep up the great job!! =D

Excellent service. Work done on time as promised.

Just got back from having a turn signal bulb replaced… For $133… Bulb is available for $7.98 online, but the intensive training required to unscrew the old bulb and screw in the new one must have been very costly indeed. Was looking for a new place to go for service on my GTI. Got a postcard saying “you don’t have to go to the dealer” As horrible as the dealer is, I very certainly would have been much better off. Oh, and they charged me $80.00 for the bulb! I said that’s some real markup on that and they told me it was 65% markup as they bought it for $25.00… Unbelievable.

You always take good care of my daughters car. Fast reliable and honest service.

Very Professional and Through in their Work. They have my Trust in their recommendations.

Always professional. I’m a 7 year customer. I’ve had several vehicles serviced here and I’ve never had to worry that the work wasn’t done properly.

You are always very helpful to me. Had my car ready on time , the time I said needed it. No loaner cars available but so good of Rayanne and Christie to get me back and forth. Thank you so much.

Thank you for polite and professional service!

Work nicely done at a reasonable price – made recommendations for (necessary!) additional work I hadn’t considered. Left one wire disconnected, but that was promptly and properly corrected. Thanks!

Service at Schearers is always meticulous and professional. The work for which I brought my car in was done well, and an inspection of potential future problems was also undertaken, enabling me to plan for future maintenance to keep my car running smoothly. I am satisfied, as always, with the quality of work and the professionalism of everyone I encountered at Schearers.

Excellent service as usual. Work was done in a timely fashion at a reasonable price. I really like the loaner car arrangement. Mike was very nice to schedule service on the same day and get the necessary parts quickly. Samantha provided a coupon from the internet. Thanks

Friendly service and fair pricing.

Very personable owner/ family. Made us feel comfortable. Explained everything that was necessary for our car upkeep. Prices better than other foreign car dealerships. Car was completed in a timely manner. Will recommend to friends. Thank you

Great experience! From the first call I made and spoke with Kristy to Mike walking me through and explaining what he was going to do. Mike also did an evaluation and let me know what to expect regarding services my car will need in the future. Exceptional customer service from beginning to end, including Samantha taking my payment. I told Mike, I am a customer for life! Well done Scherrers!! Jim Rowlands

Shearer’s yet again provided exceptional service! I am always informed of any maintenance requirements, reasons for, and associated costs before any actions are taken. They offered flexibility for returning home while the work was done in terms of a loaner car or ride. Everyone with whom I spoke was knowledgeable, courteous, and supportive. I highly recommend Shearer’s to service your car!

Always very nice and accommodating being that I live in Vermont. Will definitely have them maintain my sons car for the next 2 years while he attends school in PA.

Incredible service at a great price. I totally trust the Schearer’s Team!
