Mini Coopers are beloved by drivers around the country for their size and reliability. That’s what makes it so distressing when your Mini has a big problem. No matter your vehicle, an overheating engine is a serious problem that a mechanic must address right away. The good news is, our expert mechanics are ready to tackle any problems you have.
Three main problems cause an engine to overheat. Your Mini Cooper’s engine is kept cool by your radiator. The radiator, in turn, requires coolant to function. Last but not least, the thermostat controls the release of coolant into the radiator. These three systems are all connected, and any disruption could cause your engine to overheat.
Your Radiator
Your Mini Cooper’s radiator does precisely what it sounds like; it radiates heat away from your engine. If the radiator has any cracks or leaks, the coolant will drip out into the chassis. That could cause corrosion in addition to causing your radiator to malfunction.
If your car seems to be going through coolant faster than usual, you may have a coolant leak in your radiator. In most cases, your radiator will need replacement. Radiator replacements are relatively commonplace, and our mechanics do them all the time.
The longer you allow your radiator to leak coolant, the more corrosion damage your engine, chassis, or other systems. If you suspect your radiator is leaking or otherwise damaged, bring your mini cooper in right away to be examined by one of our trained technicians.
Leaking or Improper Coolant
Another possible problem is an improper mixture of coolant. When adding coolant to your tank, you must use an even mixture of coolant and purified water. If you do not measure carefully, the coolant will not mix well. Improperly mixed coolant will not carry heat away within your radiator, leading to an overheating engine.
If your coolant is too thick, it may solidify inside the radiator and cause build-up. On the other hand, if your coolant is too watery, it will not correctly carry heat and run out much quicker.
Lastly, if the water you use is full of calcium and magnesium, calcium carbonate may form inside your radiator or coolant tank. Calcium carbonate is a hard, chalky substance that forms when tap water reacts to heat. If deposits are allowed to form inside your vehicle, you are at risk for blockages and corrosion, which both cause damage to the radiator, coolant tank, and engine.
Engine Thermostat Issues
Lastly, your thermostat might be reading improperly or broken entirely. The thermostat is responsible for determining how much coolant to release into your radiator to ensure your engine stays at an optimal temperature.
The thermostat operates a valve that allows coolant to pass into the radiator, cooling your engine. If your thermostat is reading too low, it will fail to cool your engine. Over time, a thermostat may become damaged or broken due to harsh weather conditions. The good news is that replacing a thermostat is an easy repair job.
While it is a simple replacement part, please leave this to the professionals. A misaligned thermostat or a thermostat that has been placed without an industrial-grade sealant can cause serious issues with your vehicle. When improperly installed, a thermostat will fail to open as the engine heats, potentially leading to an engine fire.
Remember that today’s cars are more delicate and difficult to fix than the cars of 30 years ago. To ensure your vehicle’s health, have your Mini Cooper serviced by a licensed technician.
