How To Fix Overheating Car

Author: |

What happens if your car overheats while you're driving? this is obviously one of the worst things you might face on the road. One of the worst possible problems for an automobile is an overheating engine. In order to keep your engine operating in any weather, modern cars include sophisticated cooling systems with several heat sensors and computer-controlled electric fans. But it's still possible to overheat. When an engine becomes too hot, it may start to warp and break, potentially resulting in permanent damage.

we are going to take a look at causes of overheating engine and see what is the best advice if your car overheats.

1.Low Coolant Fluid

Coolant Fluid

Coolant travels to the radiator where it is cooled after absorbing heat from the engine. It goes through the engine again after losing the heat. The system won't be able to adequately cool the engine if there isn't enough coolant in it. Keep in mind that if the coolant contains pollutants as well, it won't function as well and might not absorb as much heat.

There is no other option in this situation besides draining your radiator and refilling it with fresh coolant. You must consult the user manual to determine how much coolant to use in your car. Some coolants might need to be mixed with water, while others might not.

2. Damaged Water Pump

Water Pump

The coolant is pumped through the engine by the water pump, where it absorbs the extra heat. Even if your coolant levels are adequate, a malfunctioning water pump could cause poor coolant circulation, which could result in an overheated engine.

You might also notice a leak in the water pump housing, in which case you need to get in touch with a professional right once.

3. Damaged Thermostat


Let's first take a quick look at what the thermostat does in your engine. The thermostat prevents coolant from entering the engine until it has heated up. The thermostat regulates the flow of coolant. When your engine first starts, the thermostat valve remains closed, preventing coolant from circulating. When the engine reaches operating temperature, the valve opens, allowing coolant to flow through the engine.

If the thermostat is broken, it may not open and allow coolant to flow in when it should, leading to overheating.

4. Damaged Radiator or Radiator Cap


One of the most important components of any combustion engine is the radiator. The place where the coolant goes to regain its cool is the radiator itself. Therefore, the coolant may remain overly heated if the radiator has sustained damage.

Radiators can malfunction for a variety of reasons. For instance, the radiator's fan may have burned out or the radiator may have physically been harmed in an accident. A coolant hose obstruction is yet another potential offender. There are numerous ways for dirt and other debris to get stuck in the cooling system.

The radiator cap is also used to maintain the pressure in your cooling system. The coolant may simply boil off and leave the system if the cap is destroyed.

while changing a damaged radiator in not what you can easily do it yourself at home, but if you have a radiator cap doesnt work properly, you can buy a new one and easily replace it yourself.

5. Damaged Head Gasket

Head Gasket

this one of the most serious problems can happen and let me make simply say, it is not cheap at all as well. Your car's head gasket keeps the cylinder head and engine block apart. If it blows, oil and coolant may enter the cooling system and combustion chamber, respectively. This can result in decreasing coolant levels without a visible leak as well as a visible coolant leak. You might also detect milky-white oil and white smoke emerging from the exhaust pipe if engine oil manages to enter the cooling system. The latter is a very significant issue, and you risk having to overhaul your damaged engine, which takes a lot of time and money, if you don't take your automobile to a mechanic.In order to rule out a broken head gasket, see a skilled technician if you notice any symptoms.

Overheating Car

what to do if you have overheating engine?

The heater should be turned on as soon as you notice the temperature gauge in the cluster rising. Although it seems paradoxical, it reduces the load on the engine's cooling system by drawing heat from the engine and into the passenger area.

After then, you must stop the vehicle and wait for it to cool. Be patient if you don't have roadside assistance; the engine will need at least 15 minutes to cool. In the interim, avoid attempting to open the hood because an overheated car's coolant could be above 200 degrees. You run the risk of getting splashed with hot water or steam once the hood is opened.

Keep an eye on the gauge and wait for it to return to normal. Put on gloves, open the hood, and locate the radiator cap after waiting at least 15 minutes and the hood is cool to the touch. You should also fill the small, clear plastic overflow reservoir mounted to the side of the radiator with coolant.

Adding coolant does nothing to address the issue that caused your engine to overheat in the first place, but it often allows you to safely drive to the nearest repair shop. You must get your vehicle to a repair shop, so contact a friend or a tow truck.
