The reasons for high temperatures in automotive engines may include but are not limited to the following:
Insufficient coolant or cooling system leakage. The coolant is an important component of the engine cooling system. If there is insufficient coolant or leakage, it can cause the engine temperature to rise.
Cooling fan malfunction. The purpose of a cooling fan is to help the radiator dissipate heat. If the fan is not working or not working properly, it can cause the engine temperature to rise.
Thermostat malfunction. The thermostat controls the circulation of coolant. If the thermostat is damaged or fails, it will affect the circulation of coolant, leading to an increase in engine temperature.
Water pump malfunction. The water pump is responsible for circulating the coolant through the engine. If the water pump is damaged or not working properly, it can cause poor coolant circulation, leading to high engine temperatures.
The radiator is blocked or dirty. If the radiator is blocked or dirty from the outside, it will affect its heat dissipation effect and cause the engine temperature to rise.
Improper use of lubricating oil or low-grade gasoline. Inappropriate lubricating oil or low-grade gasoline may cause increased internal friction in the engine, generate excessive heat, and cause high engine temperatures.
Insufficient intake volume. Air intake system issues may cause incomplete engine combustion, generate excessive heat, and cause an increase in engine temperature.
Internal engine malfunction. Internal faults such as improper ignition timing and cylinder gasket erosion may also cause high engine temperatures.
Solving these problems usually requires professional inspection and maintenance, including replacing damaged components, cleaning the radiator, inspecting and replacing the coolant, etc. When encountering high temperature problems with the engine, you should first pull over to the side of the car, but do not immediately turn off the engine to avoid damage caused by overheating. Then contact professional maintenance personnel as soon as possible for inspection and repair.
