The engine overheating is one of the most frequent problems that can cause big trouble if not solved in time. But what causes this problem in car engines and how can it be prevented? The cooling system of a car is responsible for regulating the temperature of the engine. This is done by circulating a coolant, usually a combination of water and antifreeze, through the engine to absorb heat and release it. This system comprises the radiator, water pump, thermostat, and cooling fan and any failure in any of these will cause the engine to overheat. Now let us discuss the reasons for overheating and what measures can be taken to eliminate them.
Reasons Your Engine Overheats
- Low Coolant Levels: Low coolant is one of the main reasons your engine overheats. Coolant or antifreeze as it is commonly referred to plays the role of maintaining the temperature of the engine. If the level of the coolant is low, it will not be able to transfer sufficient heat from the engine, and this results in high temperatures. Periodically inspecting and refilling your coolant is one of the easiest methods to avoid overheating.
- Radiator Problems: A radiator has the function of cooling the coolant before it is pumped back into the engine again. The radiator cannot release heat if it is blocked by dirt, debris, or corrosion that builds up on the surface of the metal tubes. When the coolant fails to get cooled through the radiator, it can cause the coolant to get very hot and result in some engine complications. Also, if there is a leak in the radiator, it leads to loss of coolant, which only worsens the overheating situation. It is important to occasionally flush the radiator and look for any signs of leakage in your cooling system.
- Malfunctioning Thermostat: The thermostat of your car controls the movement of the coolant from the engine to the radiator and vice versa. It usually opens and closes based on the temperature of the engine. If this thermostat is stuck in the closed position then no coolant will be allowed to circulate and the engine will overheat. Replacing a faulty thermostat is a relatively cheap task that can help avoid more serious problems.
- Bad Water Pump: Water pump is the central part of the automobile cooling system that circulates the coolant in the engine. If the water pump fails, the coolant does not flow, and this causes overheating. Some symptoms of a bad water pump are coolant leakage, strange sound when the car is running, and white steam from the engine. If you experience some difficulties with your water pump, it is high time you got it checked, and if it is bad, replace it because a bad water pump can cause severe damage to your engine.
- Faulty Cooling Fan: The cooling fan assists in the circulation of air over the radiator particularly when the car is stationary or moving slowly. If the cooling fan is not functioning properly, the radiator cannot cool the coolant and this can result in overheating. Some of the frequent problems that affect the cooling fan are a defective fan motor or blown fuse. Cooling fan troubleshooting is a complex process, and if you have problems with it, you should contact a mechanic for assistance.
Preventing Engine Overheating
To avoid getting an engine overheated there is a need to do some regular maintenance and also be able to recognize some symptoms that indicate that something is wrong. Make it a habit to check your coolant and look at your radiator, hoses, and belts and see if they are worn out or leaking. Be aware of your temperature gauge, especially during the hot summer or if you are driving for a long distance. If you observe that your engine is running hot, you need to take it to a mechanic for corrective action before the situation gets worse.
