Is your Mini losing coolant without an obvious leak? If you are always refilling your coolant yet you cannot seem to locate the source of the leak, your radiator expansion tank could be to blame. A crack or break in this cooling system part can result in the slow leakage of the coolant and ultimately result in overheating of the engine . Here is a breakdown of what a radiator expansion tank does and the symptoms that you should watch out for to know the tank is failing.
What Is the Radiator Expansion Tank?
Your Mini’s radiator expansion tank is responsible for the performance of the engine cooling system . It stores some amount of coolant when the coolant in the engine increases due to heat or expansion then releases these coolants when the engine temperature has decreased due to cooling. This system assists in regulating the amount and pressure of the coolant to ensure that the engine does not overheat. That is why, if the expansion tank is not functioning properly, your engine could be in a dangerous position.
Signs Your Radiator Expansion Tank Is Failing
- Coolant Leaks: One of the first things that will indicate that your radiator expansion tank is faulty is if you see a leakage of coolant. If you see green or orange colored liquid on the ground under your Mini, then it could be that the expansion tank has a leak. Expansion tanks made of plastic deteriorate with time and often crack up at extreme temperatures leading to leakage of coolants.
- Engine Overheating: If the engine of your car is prone to overheating most of the time, then you might have a faulty expansion tank . The tank is responsible for storing and controlling the amount of coolant and if the tank is faulty then the engine may not receive sufficient coolant to cool it. Overheating can cause more problems to the engine and that is why it needs to be fixed as early as possible.
- Low Coolant Warning Light: Some of the latest models of the Mini brand come with a low coolant light. This light usually means that there is an issue with your cooling system. It could be that the car just needs some more coolant added to the system, but the expansion tank should also be looked at for any signs of leakage or damage.
- Visible Cracks: If you take your car for a service and open the hood to check the expansion tank, you might find that the plastic has developed some cracks or has changed color. These tanks over time become fragile and any sign of a crack on the outer surface is an indication that the tank requires replacement.
What Factors Make Radiator Expansion Tanks Fail?
- Age and Wear: The material used in the construction of the expansion tank is plastic which degrades over time and becomes brittle . This brittleness makes the surface prone to cracking and leakage, especially in older vehicles.
- Extreme Temperatures: Fluctuations in temperature also affect the plastic tank by exerting pressure on the walls of the tank. Your expansion tank may be more likely to fail if you reside in an area that has a very cold or hot climate.
- Poor Coolant Quality: When using the wrong or inferior quality coolant, there might be some chemical reactions that may lead to the deterioration of the plastic used in making the expansion tank. One should always ensure that he or she is using the right type of coolant for the Mini since the use of the wrong coolant will cause early wear of the cooling system parts.

The service light illuminates on your car’s dashboard—it’s time for routine maintenance. If you’ve seen this notification pop up and wondered why your car says “maintenance required,” it’s because most car manufacturers have schedules for basic repairs and tune-ups. Regular maintenance like rotating tires, replacing spark plugs and filters, and changing brake fluid can keep your car running well and prevent bigger repairs down the road. But you might be asking: Do I really need to do all the maintenance they recommend? Should I follow the schedule exactly? The short answer is “yes.” Here are three surprising things you might not know about factory-scheduled maintenance. 1. A ton of research goes into the recommendations. Most manufacturers have spent millions of dollars to figure out what items need to be serviced or inspected for each year, make, and model of their cars. Some items are due by mileage, some by time, and some by whatever comes first. These recommendations are developed by the engineers and techs who designed and built your vehicle (not by the sales team at the dealership), and they are customized to your car. In other words, they’re legitimate. 2. They vary by make, year, and model—so make sure you know what your car requires. Not every manufacturer is the same when it comes to when and what services are due at specific mileages. The manufacturer’s maintenance schedule not only varies by make but often by year and model as well. For instance, spark plugs are due every 40,000 miles on most Volkswagen and Audi models; some, however, on some, they’re due every 50,000 miles. On Mercedes, spark plugs are due every 60,000 miles or 5 years—whichever comes first. 3. It’s important to pay attention to them. We promise: The manufacturer’s recommendations aren’t part of a secret marketing deal between car makers and repair shops. These really are essential repairs that will keep your car driving longer. These routine tune-ups prevent damage to bigger, more expensive parts of your car. And if you have a specialty car like a BMW or Mercedes, these recommendations become even more important—high-performance vehicles require high-end care. If you want to get high mileage out of your car—and peak performance while you own it—it’s time to stop ignoring the manufacturer’s maintenance schedule and build a relationship with an auto repair shop that understands European and Asian vehicles. At Import Specialty Service , we know the routine maintenance requirements of European and Asian imports like the backs of our hands. Our expert technicians will not only keep your car in top shape, but they will also advise you on what maintenance is necessary for your specific make and model.

It’s hard to beat springtime in Nashville—sunny days, lush green trees, and flowers in bloom. The only downside? Nashville’s notorious spring allergies. While you might blame the yellow coat of pollen on your car’s exterior for your sniffles, that isn’t the only place pollen is building up in your vehicle. Your cabin air filter is constantly working to filter out dust, pollen, and other allergens. The health of your cabin air filter can seriously impact your health and the air quality of your car’s interior. Over time, cabin air filters become clogged and lose effectiveness. Just like the air filters in your home HVAC, it’s essential to regularly check and replace cabin air filters. Here are six signs that you need to replace your cabin air filter: 1. Reduced Airflow from Vents One of the most noticeable signs of a clogged cabin air filter is weak airflow when using the heating or air conditioning system. If it feels like your vents aren’t pushing out as much air as they used to, a dirty filter could be the culprit. 2. Unpleasant Odors Inside the Car A musty, stale, or dusty smell inside your vehicle can be a sign that your cabin air filter is overdue for a change. When the filter becomes clogged with dirt, bacteria, and mold, it can trap unpleasant odors and recirculate them throughout your car. Failure to have filters changed on a regular basis may result in bacteria or mold infestation of the evaporator core. 3. Increased Allergy or Respiratory Issues If you or your passengers start experiencing more allergy symptoms, sneezing, or respiratory discomfort while driving, it could be due to a dirty cabin air filter. A clogged filter allows allergens and pollutants to enter the cabin, reducing air quality. 4. Foggy Windows That Take Longer to Clear Your car’s cabin air filter helps regulate airflow, which plays a role in defogging your windows. If your windshield takes longer to clear up on humid or cold days, your filter may be too dirty to allow proper airflow. 5. Unusual Noises from the HVAC System A clogged cabin air filter can force your vehicle’s HVAC system to work harder, sometimes resulting in strange whistling or buzzing sounds when the fan is on. If you hear unusual noises coming from the vents, it’s worth checking the filter. 6. Visible Dirt and Debris on the Filter If you remove the cabin air filter and see excessive dirt, leaves, or debris built up, it’s time for a replacement. A clean filter is typically white or off-white, while a dirty one will appear dark and clogged with contaminants. How Often Should Your Cabin Air Filter Be Changed? For most European and Asian cars, cabin air filters are recommended 1x a year or every 15,000-20,000 miles. However, if you frequently drive in urban areas, dusty conditions, or pollen-heavy seasons in Nashville, you may need to replace it more often.

Our team of expert car mechanics can advise you on how to keep your car running smoothly and you feeling your best. At Import Specialty Service , we specialize in European car repair and Asian car repair in Nashville.

Is your Infiniti’s navigation system your primary means of navigation, only to become unresponsive, provide incorrect directions, or not load maps at all? Infiniti has developed an infotainment system that is supposed to enhance the ease of driving, but it can be a lot to deal with when it develops some issues. A poor navigation system is quite irritating, especially if you are in an unfamiliar area or on a tight schedule. If you are having issues with your car’s navigation system, you are not alone. Many other users of Infiniti cars have also complained of the same issue. Some of the problems reported by many Infiniti owners include slow response, wrong information on the map, or even complete system breakdown. Here are the causes of these glitches and how to rectify them so that you can have a reliable system again. Why Does the Infiniti Navigation System Go Bad? Software Bugs and Outdated Maps: Infiniti’s car navigation system utilizes software that requires updates at some point to work as expected. If the system has not been updated for some time, it may contain errors or outdated information on the map, affecting the directions and roads. The system may also lock up or crash due to software errors. Interference of GPS Signal: A bad GPS signal can be a major issue affecting the navigation of your Infiniti. This can occur when driving through tunnels, big buildings such as in towns or cities, or areas with bad satellite signals. Sometimes, it can be due to a faulty GPS antenna that stops the system from getting the correct location information. Electrical Issues and Wiring Problems: The navigation system utilizes several electrical connections and circuits. If there is a problem with the power supply or faulty wiring, the system may not work as expected. Some issues include the screen fading, the system freezing, or the audio getting interrupted. Hard Drive or SD Card Failure: In some Infiniti models, the maps are stored on the car's navigation system's hard drive or SD card. If this storage device is damaged or corrupted, the system may take a long time to load the map or freeze. A faulty hard drive can also cause slow boot time and interrupted navigation capability. Touchscreen Issues: Other issues reported by Infiniti owners include unresponsive buttons or a frozen screen. These can make it difficult to enter the address displayed on the screen or even to change the settings. These problems can be caused by software issues or physical damage to the screen. How to Troubleshoot Infiniti Navigation System Problems Check GPS Signal Strength: If the system frequently loses signal, try going to a more open area to enable the GPS to lock on to satellites. Some problems may require a technician to check the GPS antenna for defects. Restart or Reset the System: If you experience a few minor issues while using your car's infotainment system, you can turn off the car and then on again to solve the problem. If the issues are not resolved, a system reboot may help fix them in the software. Check Touchscreen and Buttons: If controls do not respond, this may be due to software problems or button damage. A professional inspection is needed to determine whether certain parts need to be repaired or replaced. Ensure You Have the Latest Software and Maps: It is always recommended to have the latest software installed in your car to avoid any hitches. Companies like Infiniti release new software to patch up some glitches and enhance other features.
