Causes of an overheating car and quick fixes

Engine overheating can happen while driving on a daily basis as well as during the summer. Particularly when the water temperature is too high, fast-moving automobiles, engines, and air conditioning systems can result in the boiling phenomenon. Engine overheating is hazardous. Unfortunate events could lead to engine damage. When the water temperature gauge’s pointer crosses into the red zone and remains there while driving at a higher speed on a highway or when getting into a car, the appropriate actions should be taken. Here’s how to deal with an overheating engine.

Overheating can be brought on by a variety of factors, including inadequate coolant, faulty cooling fans, thermostats, and coolant temperature sensors. It can result in a costly engine failure if you handle it improperly. Overheating can therefore be effectively reduced by prompt detection and proper disposal.

What impact does an overheated engine have on the engine?

1. decreased aeration effectiveness, which reduced engine power.

2. Pre-ignition and deflagration are more likely, which interferes with the engine’s regular operation and increases the risk of early damage from additional impact loads.

3. The moving parts can no longer move normally or can even sustain damage because the normal gap between the parts has been destroyed.

4. It damages the part’s ability to deform because the mechanical properties of the metal material are diminished.

5. The friction and wear of the parts are made worse by the deterioration of the lubrication situation.

How is engine overheating brought on?

The water temperature in the tank can become too high due to several factors, the first of which is inadequate engine cooling. The more internal scale that accumulates in the water tank over time, the worse the radiator’s ability to dissipate heat will be. The water with too high temperature will not release heat, and it will evolve into a “pan”. Furthermore, poor heat dissipation is frequently caused by the radiator’s ventilation hole. Clean it up with a water gun if the external obstruction is not ventilated. Clean the radiator’s interior with a cleaning solution if it is blocked.

Second, inadequate heat dissipation is caused by the cooling system’s malfunction. Check the fan belt’s tightness and the condition of the blades now to see if they are bent or broken.

Third, to ensure that the engine operates within a suitable temperature range, the thermostat automatically modifies the amount of water entering the radiator in accordance with the temperature of the cooling water. This feature can help reduce energy consumption. Verify the thermostat’s functionality if the engine is overheating. opens up completely at 83°C after starting at 70°C. The thermostat can be submerged in water for heating inspection when the height of the fully opened valve is not less than 9 mm. It is necessary to replace the thermostat if it cannot be opened or if the opening degree is insufficient.

Last but not least, avoid turning off the engine when it is overheated. Do not turn off the engine and wait for it to cool if the fan belt and coolant circulation are normal. People typically feel that the engine cools down more quickly after the flame out. In reality, the cooling fan and coolant circulation will shut off after the engine has cooled, which will raise the engine’s temperature. On either side of the bumper surrounding the engine compartment are two spiral fans. One is an engine cooling fan that operates when the engine is running, and the other is an air conditioning fan that operates when the air conditioner is turned on. Consequently, it is preferable to turn on the air conditioner at the same time as starting the engine if the fan belt is still intact when the car overheats, as this will speed up engine cooling.
