Car Heat Gauge 

Why is my car overheating? If you've ever asked yourself this question, then it's important to understand what causes this to occur for future prevention. A car can overheat for many reasons, from cooling system leaks to radiator troubles. For reference, the optimal temperature range for most cars is between 195 and 200 degrees. So if you ever notice your temperature gauge rising above these figures, get out of your car immediately. Driving an overheated car is dangerous, and doing so will likely result in more expensive repairs later on.

Here, the experts at Auffenberg Ford Belleville explain the reasons a car would overheat. Make sure to get in touch if you have any questions or need additional advice.

What Does It Mean When Your Car Overheats?

Typically, an overheated car serves as a signal to Waterloo drivers that there is a bigger issue afoot, and that it should be handled immediately. Some common reasons a car would overheat include:

  • Cooling system leak: More often than not, a cooling system leak is the cause of an overheated car. The cooling system is comprised of the radiator, head gasket, thermostat, water pump, and hoses. All components are susceptible to leaking, and you should check your coolant often.
  • Coolant issue: Adding the wrong kind of coolant to your car or maintaining the improper coolant-to-water ratio makes your engine more prone to overheating. The proper coolant-to-water ratio is 50/50.
  • Coolant hose blockage: Dirt and debris often enter your cooling system as you drive around Belleville. These can cause a coolant hose blockage, which in turn can prompt an overheated car.
  • Radiator problem: Blockages or leaks in the radiator, as well as a broken radiator fan, are all reasons a car might overheat.
  • Broken water pump: The water pump's main responsibility is delivering coolant throughout the cooling system. A leak or shifted pump shaft may result in overheating.

What to Do When a Car Overheats


Mascoutah drivers often won't realize that their car is overheating until they're already on the road. Here is what to do when a car overheats:

  • Turn off the air conditioning, and instead activate the heat at full blast. While this is certainly uncomfortable, it draws heat from the engine, allowing it to cool down.
  • Pull over to safety, and wait for about 30 minutes before popping the hood.
  • Call a towing service, and have them bring your vehicle to a nearby mechanic.
