Why Is My Car Overheating?

Overheating Car Engine

There could be a number of reasons why a vehicle would overheat, ranging from the cooling system to a problem with your radiator. Every car has a “normal” place for its temperature gauge sits at, but most operate between 195 and 200 degrees Fahrenheit. When you start your vehicle, if you notice the temperature gauge is higher than usual, do not drive the car, because it can put you in danger and cause more significant issues down the road.

Below is a look at what causes a car to overheat, and feel free to call us with any questions.


What Does It Mean When Your Car Overheats?

An overheated car is a sign of a much larger issue that needs to get addressed and fixed as soon as possible. The following are the most common reasons a vehicle would overheat:

  • There’s a leak in the cooling system – The radiator, hoses, water pump, head gasket, and thermostat housing are components of the cooling system, which can be susceptible to leaks.
  • There’s a problem with your coolant – The wrong coolant or an improper coolant-to-water ratio (50/50 is proper) can cause the engine to overheat.
  • There’s a blockage in the coolant hose – Since dirt and debris can get in your cooling system while driving on Eagan roads, it can cause blockages in the coolant hose.
  • There’s an issue with the radiator – There could be a blockage, leak, or something wrong with the radiator fan, which could cause a car to overheat.
  • Your car’s water pump is broken – The water pump sends engine coolant throughout the cooling system. If yours has a leak or a shifted pump shaft, it can cause overheating.

What Should I Do When a Car Overheats?

Unfortunately, you may not experience your vehicle overheating until you’re already on Woodbury roads. Don’t fret — if you’re running the air conditioner, turn it off and run your heat at full blast. We know it will get uncomfortable, but it helps pull heat from the engine until you can pull over to a safe area. Do not attempt to pop the hood by hand for at least 30 minutes. It’s best to tow your vehicle to our Inver Grove Heights service center.
