We all know that how it feels when the car is overheating. Many drivers driving slightly older cars fear that their engines will overheat in a traffic jam – on hot days, cars often stand behind the steam on the side of the road. But you can do something about that.


Why Is My Car Overheating?

One of the main causes of car overheating is a low coolant level. Hoses and various screw connections will wear out over time. In this case, the system is no longer sealed and fluid may leak out. The circuit is then filled with air which does not have the properties necessary for proper engine cooling. Sometimes the cooler itself leaks, i.e. B. if damaged in a collision.

If the coolant level looks correct but the operating temperature continues to rise, your thermostat may be stuck or clogged. The additional cooling circuit must be opened when the engine is hot. The defective device cannot fulfill its function and limits the flow of coolant. This is especially common when poor quality replacement parts are used.

The engine is cooled by the coolant that flows through it and absorbs heat. The cooler is constantly moving. This cycle is provided by a water pump. So, if the pump breaks or the belt gets stuck or torn, that is the source of the problem because it can no longer properly dissipate excess heat.

Another reason coolant circulation can be cut off is due to blockage. The coolant hose or line may become clogged. Some drivers still use water as a coolant today. If the water is not distilled, limestone will likely form in the system. Heat transfer gradually becomes less efficient until the flow is completely blocked.

However, the problem may not be related to the refrigerant or circulation. The engine is not only cooled with coolant, but also with oil. It is used as a lubricant to reduce friction between engine components. If the oil level is low, these components will not be properly lubricated. They generate excessive heat when rubbing against each other.

Low coolant levels can also indicate another problem with the engine itself: a burst cylinder head gasket. This closes the combustion chamber and prevents oil and coolant from mixing. When they explode, coolant escapes and the air is sucked in, putting the engine at high risk.

Another component of an engine cooling system that can cause car overheating is ventilation. Improper ventilation cannot create airflow which cools the motor and protects it from overheating.


How to Fix Overheating Car

If your car is overheating you can do a few certain things to fix it.

If you find that the temperature gauge shows that your engine is warmer than it should be, first check the coolant level. Add liquid if not enough. However, this is a short term solution. If the coolant level is low, check for leaks. Check coolant, hoses, fittings, and seals for leaks. If one of the components is damaged, it must be replaced immediately.

Make sure the cooler has completely cooled down before removing the filler cover. Otherwise, you could catch fire if the pressurized coolant suddenly leaks out. If the coolant tank is full but the engine is still hot, the problem could be with a faulty thermostat. This can be checked very easily. Handle the bottom of the radiator or bottom radiator hose with care when the engine is warm. As they cool, the flow of coolant is restricted. You find the cause. By changing the thermostat, you should be able to stop the engine from overheating.

Using water as coolant or using poor quality auto chemicals increases the risk of clogging your cooling system. If you suspect you need to remove the radiator and have it checked. Rinse the cooler if you find traces of dirt. It is advisable to do this every two or three years.

Check the oil level to get rid of excess heat due to insufficient oil. Stop the engine and let it cool down. Remove the dipstick, wipe the oil, and apply it all over the surface. Wait a minute, then remove the dipstick and check the level. The oil must be between the two brands. If it comes down, it’s not enough. Put a little oil in the engine. Make sure the booth is between the signs. Check the engine for leaks and traces of oil leaks.

If you’re worried that your coolant pump is overheating the engine, it’s best to check the area. There shall be no sign of coolant leakage. It’s a good idea to also check the spool and make sure the rope is tightened properly. Listen for the sound of the car when the engine starts. When the cover is open, you can hear the coolant pump running. If you hear a little noise, it could be due to worn bearings. If you experience any of these symptoms, the pump or belt should be replaced.

This is clearly a bad sign for the white steam that comes out of the exhaust as coolant enters the combustion chamber. The cylinder head gasket that is blown separates the oil and coolant so that it can no longer mix. You will have to contact an auto technician to replace the seal.

It’s easy to see a broken vent. When your engine reaches a certain operating temperature, the vents will turn on automatically, or you can turn them on if your car is equipped with air conditioning. There are a number of reasons why this might not work. For example, a lighter, temperature sensor, or electric fan may need to be replaced.

The engine is the heart of every vehicle and must therefore be treated with great care. Overheating significantly shortens the life of the unit and sometimes a major overhaul can cost a car. Always monitor the warning lights and temperature sensors, check the coolant and oil level, and make sure that nothing is leaking if you see a puddle of liquid under the car.
