What is the normal position for the Leiling water temperature gauge?

On the Leiling water temperature gauge, the black dot between C and H indicates the water temperature, with C on the left representing 60 degrees and H on the right representing 110 degrees. The middle position indicates the normal water temperature. Common troubleshooting methods for abnormal water temperature are as follows: 1. If the temperature is too high or the temperature indicator light keeps flashing, stop and check whether the radiator coolant is normal and whether there are any leaks in the radiator, hoses, or joints. If no abnormalities are found during the external inspection, you can refill the coolant as required and continue driving. If the temperature remains high after driving for a while and you find the coolant level has decreased upon stopping to check, this is likely due to a sand hole or perforation in the cylinder block's water jacket causing leakage. This fault should be repaired upon discovery. 2. When the engine temperature is too high, you can touch the upper and lower hoses to determine the fault by their temperature difference. If there is a significant temperature difference between the two hoses, it can be concluded that the thermostat is not working. If you cannot purchase a replacement part immediately, you can remove the thermostat as an emergency measure. 3. If there is air in the cooling system, it can create an airlock, impairing coolant circulation and causing the engine temperature to rise too high. The following method can be used to bleed the air: Run the engine at high speed and gently unscrew the radiator cap until gas begins to escape. Some coolant may escape with the gas. Repeat this process several times until you feel all the gas has been released. After resolving the fault, replenish the coolant promptly.
Having driven for so many years, I've found the coolant temperature gauge to be quite reliable. For the Levin, the normal temperature is right at the middle mark on the dashboard, usually around 90 degrees, neither leaning left nor right. If it gets too high, you should worry about engine overheating, like smoke coming out, and severe cases can damage parts; too low is also bad, as it takes forever to get warm air after a cold start, wastes fuel, and affects performance. Last time my temperature hit the red line, I pulled over immediately to check if the coolant was low. I'd advise new drivers to glance at the temperature gauge more often and make it a habit, adding some antifreeze during routine maintenance. If anything seems off, don't push it—get it checked at a repair shop.
