What Causes a Car to Overheat?

While there are several reasons why your car is overheating, these are the most common car overheating causes on Martinsville roads. See if your situation matches any of the following scenarios:

  • Leaking Cooling System – A leaking cooling system is the most common reason a car overheats. This cooling system includes a radiator, hoses, a water pump, a head gasket, and thermostat housing. If one of these components breaks or leaks, your car will overheat.
  • The Coolant Hose is Blocked – Even with no leak in your system, your car might still overheat if there’s a block in the coolant hose. Sometimes dirt or debris can accumulate inside it and prevent the system from functioning properly.
  • The Wrong Coolant Mixture – Most cars require a 50/50 water-to-coolant ratio. If the mixture is incorrectly mixed, your vehicle could overheat.
  • Radiator Problems – If your radiator is broken, blocked, or leaking, it’s another reason your car could overheat.
  • Broken Water Pump – A leak or a shifted pump shaft may prevent your water pump from delivering coolant where it’s needed and cause your vehicle to overheat.

What to Do When a Car Overheats

If you are out cruising Danville roads and experience one of the issues above, there are several things you should do immediately:

  • Safely pull over to the side of the road and turn off your vehicle as soon as you can. To avoid getting burned, it’s important that you wait at least 30 minutes before popping the hood.
  • If you’re using the air conditioning, stop right away and set the heat to full blast. You’ll be uncomfortable, but it will help eradicate the excessive heat from your engine block.
  • Call Roadside Assistance, or another towing service to take you to Gunter Nissan of Martinsville for service.

Remember, driving your car around Roanoke while it’s overheating is a bad idea and can lead to long-term damage.
