There are multiple reasons a car would overheat, from a leak in the cooling system to an issue with the radiator. Every vehicle has a "normal" place for their temperature gauge to sit, but most cars tend to operate between 90 and 93 degrees Celsius. If you start your car and notice the temperature gauge is reading far higher than normal, do not drive the car. Driving an overheating car can put you in danger, and it will only cause bigger, costlier issues down the road.

What Does It Mean When Your Car Overheats?
An overheated car is a clear signal to you that there is a bigger issue to take care of. Here are the most common reasons overheating might happen:
- There's a leak in the cooling system: Most often, a leak in the cooling system is what's causing your car to overheat. The radiator, hoses, water pump, head gasket, and thermostat housing are all components of the cooling system, and all can be susceptible to leaks.
- There's a problem with your coolant: If the wrong coolant was put in your car, or you have an improper coolant-to-water ratio (50/50 is proper), your engine may be prone to overheating.
- There's a blockage in the coolant hose: The next possible culprit is the coolant hose. There are plenty of opportunities for dirt and debris to get in your cooling system. Unfortunately, this can cause blockages in the coolant hose.
- There's an issue with the radiator: Radiator issues are another common reason a car would overheat. There could be a blockage, a leak, or something wrong with the radiator fan, and all could cause a car to overheat.
- Your car's water pump is broken: The water pump sends engine coolant throughout the cooling system. Yours may be suffering from a leak or a shifted pump shaft, both of which often cause overheating.
What to Do When a Car Overheats
Unfortunately, your car may not overheat until you've already hit the road. If you're running the air conditioning, turn it off and instead run your heat at full blast. It may be uncomfortable, but it will help pull heat off your engine. When you're able to pull over to safety, you should not attempt to pop the hood by hand for at least 30 minutes. The best way to maintain your safety and that of nearby drivers is to call a towing service to pick your car up and bring it to your mechanic of choice.
