How to Recognize the Symptoms That Your Car Engine Is Overheated?

Engine overheating is one of the most serious and dangerous vehicle problems. The consequences of this error could result in major component failure. When the engine is turned on, a lot of heat is produced. To prevent overheating, each car has a cooling system that keeps the temperature within normal limits. An experienced driver understands that keeping the engine cool is a great way to extend the life of a vehicle and avoid major problems. Beginners may not realize, due to a lack of experience, that if the temperature exceeds a certain threshold, their vehicle will break down and cause significant damage. Continue reading to learn about the warning signs you should always look for in order to catch engine overheating problems in time.

Signs of an Overheated Engine

Nowadays, modern vehicles are equipped with onboard computers that monitor the operating parameters of the motor. In such cars, everything is simple: the error “engine overheating” lights up on the display if its temperature exceeds the permissible limit. If there is no such sensor, you need to pay attention to the temperature sensor's readings. If the arrow enters the red zone, it is urgently necessary to stop the vehicle. The next sign of overheating may be steam from under the hood of the car. Also, a sign of overheating is a characteristic ringing when the engine is running. This is because the walls of the combustion chamber when overheated, provoke abnormal combustion of the fuel mixture.

At times, it is possible that the sensor has failed, or the indicator is faulty. Even if the engine overheat sensor does not signal, the operating temperature may be significantly higher than the optimum. The following symptoms often mean that the motor is overheated:

  • The fan runs longer than usual
  • interior heating or cooling does not work.
  • Car power drops noticeably.
  • Engine oil changes color.

Reasons for Engine Overheating

Coolant Leakage - Fluid leaks can be caused by damage to the radiator, pipes, or loose clamps. If the engine gasket is broken, the liquid goes into the oil or burns out in the cylinders.

Thermostat Malfunction - If the thermostat is stuck in one of the positions, the engine may overheat or cool too much.

Fan Problems - A malfunction of the cooling system fan can be caused by a failure of the sensor for turning it on, a motor, or damage to the wiring.

Dirty Radiator - Over time, the radiator cavities become clogged with dust and dirt. As a result, its efficiency is reduced.

Water Pump Malfunction - A pump failure or a broken or slipping belt disrupts the coolant's circulation, resulting in its temperature rising locally and the antifreeze boils.

Low Oil Level - Lack of lubrication causes friction in the engine, which in turn increases heat.

High Ambient Temperature - If it is too hot outside, the cooling system's efficiency may not be enough, especially if the car is not moving.

Clogged Catalytic Converter - It prevents the passage of exhaust gases which causes an accumulation of additional heat in the engine and increases its load.

Conclusion

The stronger the overheating, the more destructive it is for the engine. High temperatures provoke accelerated wear and destroy motor units. A few tens of seconds of extreme overheating are enough to send the motor to a landfill. Therefore, the flashing of the coolant warning lamp must not be ignored.
