What causes the car engine temperature to be too high?
2 Answers
The reasons for the car engine temperature being too high are: 1. Lack of coolant, such as water pump leakage, pipeline damage, or radiator damage; 2. The thermostat is faulty, causing the water temperature to be too high. The thermostat cannot open, hindering the flow of coolant inside the engine and causing the coolant temperature to rise; 3. The cooling fan is not working properly, leading to poor heat dissipation of the coolant; 4. The water pump is malfunctioning, and its rotation is not smooth. The car engine is the device that provides power to the car, serving as the heart of the car, determining its power, economy, stability, and environmental friendliness. Depending on the power source, car engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines.
I've been driving for several years and have encountered engine overheating quite a few times, mostly due to issues with the cooling system. The most common problem is insufficient or leaking coolant, as the coolant is responsible for absorbing engine heat and transferring it to the radiator. If the coolant level is too low, the temperature can easily spike when driving in hot weather. Fan failure is also a major issue, especially when the fan doesn't spin at low speeds or when idling, leading to poor heat dissipation. A stuck thermostat can prevent coolant from circulating properly, causing heat buildup. A damaged water pump or a radiator clogged with dust affecting ventilation can also cause the engine to overheat. Once, my temperature gauge suddenly alarmed on the highway, so I quickly pulled over to check and found that the fan belt was loose. The solution is to stop the car immediately, turn off the engine, and let it cool for half an hour. If the coolant is low, add some purified water as an emergency measure. However, you should quickly find a repair shop to check for leaks, as continuous overheating can damage the cylinder head gasket or the engine block, and repairs can cost much more than a few hundred dollars. For regular maintenance, I check the coolant level and fan condition every three months to prevent most problems.
