What is the reason for the red light on the BYD F0 water temperature gauge?
2 Answers
It indicates that the water temperature is too high, and it is not recommended to continue driving. The reasons are as follows: 1. Overheating: The red light on the water temperature gauge means the temperature is excessively high, and you should not continue to drive the vehicle. High temperatures can easily cause engine problems. 2. Precautions: If you must continue driving, wait for the engine temperature to drop. Also, check if the coolant level is low. In severe cases, it may affect the cylinder head or cause cylinder scoring. 3. Measures: This situation is likely caused by low engine coolant levels. It is recommended to check the coolant level and replenish it promptly if it is low.
That time when I was driving my BYD F0, the coolant temperature warning light suddenly turned red, which gave me a scare. Overheating is quite common in small cars like this, mainly due to reasons like insufficient coolant, a faulty water pump, or a non-functioning fan leading to poor heat dissipation. I often drive in the city, and during traffic jams, the engine temperature can easily spike. If there's a leak or blockage in the cooling system, the warning light will come on. Last time, I checked the coolant level in the radiator, and sure enough, it was quite low. Adding some purified water gave me temporary relief. But this is just a stopgap measure. In the long run, if the water pump is worn out or the thermostat is stuck, the system can't circulate coolant, and the temperature will rise even faster. If the fan isn't working, the motor might be broken. In such situations, I immediately pull over, turn off the engine, and open the hood to let it cool down naturally. Otherwise, engine overheating can cause cylinder scoring or even total failure. I recommend that beginners always carry some coolant and avoid pushing the car under such conditions. The safest solution is to seek professional repair services right away.
