What are the reasons for the car's water temperature always showing high?

There are several reasons why a car's water temperature always shows high, including insufficient coolant, malfunctioning cooling fan, and faulty circulation water pump. Insufficient coolant: Coolant leakage or shortage can cause the engine's water temperature to rise. In this case, you should check the coolant level. If it's insufficient, first top it up to the appropriate level, then check again after a few days to see if the level has dropped significantly. If it has, locate the leak and repair it. Since there are many small tubes on the coolant reservoir, if the coolant leakage is due to loose connections, you can wrap the damaged tube with a string or plastic bag. If it's just a matter of insufficient coolant, simply add more antifreeze. Note that you should wait for the coolant temperature to drop before adding antifreeze. In an emergency, clean water can be used as a temporary substitute for coolant. However, it's important to note that clean water should only be used as a temporary solution. Once the water temperature returns to normal, you should replace it with new coolant as soon as possible. Malfunctioning cooling fan: If the cooling fan is faulty, when the vehicle is running at high speeds, the heat generated cannot be transferred to the coolant in time, affecting heat dissipation and causing the coolant temperature to rise, leading to issues like boiling. Timely repair is necessary. Faulty circulation water pump: Water pump failures can include seized bearings and damaged impellers. Seized bearings are relatively rare, while damaged impellers are more common, such as cracked impellers or impellers loosening from the pump shaft, which can slow down the circulation of coolant and easily cause the engine to overheat. Timely repair is required.
