Why Is My Car Overheating?

man upset in front of overheating car
Most cars have a normal engine temperature between 195°F and 200°F, but check your owner’s manual more specific information on your model. The engine can overheat for a number of reasons–whether there is a coolant leak, an issue with the radiator, or something else. To see whether you have an overheated engine, check your vehicle’s temperature gauge on the instrument panel. If the needle is getting close to the red section of the dial, it may be time to drive to your local authorized service center. Learn what causes a car to overheat with Tulley Mazda below, and contact us if you have any questions in the Hudson area.


What Does It Mean When Your Car Overheats?

When you have an overheated engine, that may mean there is a bigger issue to take care of. Here are the most common reasons a car would overheat:

  • 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.
  • A problem with the coolant itself 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.
  • 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, which can cause blockages in the coolant hose.
  • Broken water pump 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.
  • 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.

What to Do When a Car Overheats

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.
  • If you have a roadside assistance service like AAA, or roadside assistance part of your vehicle warranty, get your car to a service center as soon as possible.

If your engine overheats after you’ve already started driving around Merrimack:

  • Assess if you are able to safely pull over to the side of the road.
  • If you cannot pull over right away, make sure the air conditioning is turned it off and run your heat at full blast, which help pull heat off your engine.
  • Once pulled over, wait at least 30 minutes before popping the hood. Once the engine cools fully, then it will be safe to pop the hood and take a look, or simply have it towed to the nearest service center.
