How Urgent Is Your Mini’s Radiator Expansion Tank Failure Repair?

Do you ever ask yourself why your Mini begins to overheat on a completely normal day? Just like any other thing, it may be seen as a trivial matter, but in an actual sense, it may be an indication of failure in the radiator expansion tank. But how pressing is the need to have this rectified? Knowing the function of the radiator expansion tank and the symptoms of failure will help you determine when to bring your car for repairs.

What Does the Radiator Expansion Tank Do?

This less popular component is a very important unit of your Mini’s cooling system. It is primarily designed to store excess coolant that may be present in the radiator in instances when your engine is hot. When the car is in operation, this coolant goes through the engine and to the radiator and when the engine cools, this coolant is pulled back ensuring that the engine does not overheat.

In other words, the expansion tank assists in regulating the coolant level in the system. Without it, your engine may overheat and it may cause a lot of damage and even cost you a lot of money to repair.

Symptoms of Radiator Expansion Tank Failure

• Coolant Leaks: The most evident symptom that a particular expansion tank is failing is leakage of coolant. If you see a pool of water on the garage floor and you realize that it is coming from your car or you find traces of coolant spilling around the engine compartment then you might have a problem in the expansion tank.
• Overheating Engine: A bad expansion tank will cause the coolant to seep out and therefore lead to low coolant levels and in turn an engine that is overheating. When your temperature gauge goes up, you could be in trouble; so keep an eye on it.

Why You Should Quickly Repair A Failing Radiator Expansion Tank

• Engine Overheating: As stated earlier on, the expansion tank is very important in ensuring that the correct level of coolant is maintained. Without it, your engine could overheat very quickly and that is something that no one would wish to happen to their vehicle. Head gasket failure, warped cylinder heads, or even a complete failure of the engine is an inevitable result of an overheated engine. These repairs can also be very costly and take a lot of time to be executed.
• Coolant Loss: An expansion tank in a bad state may result in a loss of coolant. If you do not have enough coolant in your engine, then the temperature of your engine will not be well controlled. This can lead to more overheating and wear and tear of more components of the engine.
• Reduced Performance: A faulty cooling system can also be a problem in your Mini since it is used in the car’s operations. When the engine is too hot, it will not perform as it should and this will lead to low power and stalling.
• Environmental Impact: A coolant leak is not good for your car and it is also toxic to the environment. Coolant is poisonous and can be lethal to animals and plants. Repairing a leaking expansion tank is also a way of preserving the environment from such bad substances.

How to Solve the Problem of a Failing Radiator Expansion Tank

• Inspect Leaks: Inspection should be done around the expansion tank and the engine compartment for any signs of leakage. If you see any signs of leakage, then it is high time to take your Mini to a mechanic for diagnosis.
• Replace Expansion Tank: If the expansion tank is cracked or damaged the tank will require replacement. This is not a very complicated or costly process, but it is a very important one for the health of your engine.
• Visit a Professional Mechanic: If you are not sure whether your radiator expansion tank is in good shape or not, then it is always advisable to seek the service of a mechanic. They are capable of doing the pressure test to check for leaks within the system and recommend the appropriate action.
