What causes the red light on the BYD F0 temperature gauge to illuminate?
2 Answers
BYD F0 temperature gauge showing a red light is likely caused by low engine coolant level. The specific explanations are as follows: 1. Reasons for the red light on the temperature gauge: One possibility is insufficient coolant, which triggers the temperature warning light. Another possibility is engine overheating, which also activates the temperature warning light. 2. It is not recommended to continue driving when the red light is on: If the temperature gauge shows a red light, you should not start or continue driving the vehicle. The red light indicates excessive temperature, and high temperatures can lead to engine issues such as blown head gaskets or excessively small gaps between mechanical components. To continue driving, you must wait for the engine temperature to drop and also check if there is any shortage of coolant.
The red light on the water temperature gauge most likely indicates insufficient coolant or engine overheating. I've repaired many BYD F0 models, and common issues with this car often involve fan or water pump failures. After stopping the car, don't panic—open the hood and check the coolant reservoir: if the level is below the min line, there's a leak or excessive evaporation; if it's normal, the fan might be stuck. In summer, high temperatures make the fan work more frequently, and older motors are prone to failure. I recall one case where a non-functioning fan caused the water temperature to skyrocket, and replacing the part solved the issue. Don't ignore this warning—minor consequences can include burst hoses, while severe cases may lead to engine failure. Safety first: when the light comes on, turn off the AC, pull over to let the car cool down, and head to a professional shop for inspection immediately.
