lighted electric water temp and oil temp gauge

What is the reason for the car temperature gauge to light up?

If the car temperature gauge is on, it means that the temperature of the car is too high or too low. In winter, the temperature gauge is bright because the temperature of the vehicle is low, and it will turn off after the vehicle has been running for a period of time. In summer, it is because the outdoor temperature is high and the temperature gauge is not bright. If it suddenly lights up after running for a period of time, it means that the temperature of the car is too high, you should turn off the engine and check whether the car is short of water or other reasons.

Why is the most complete fault light of the water and oil tank on? reason:

1. The water tank is short of water, the water temperature sensor, the thermostat, the water tank is too dirty, and the electronic fan does not turn the impeller of the water pump;
2. When the water temperature alarm light is on, it does not necessarily mean that there is no water shortage. If the water temperature alarm light is on, it means that the temperature is too high. It cannot be sure that it is a lack of water. Even if there is no water shortage, the temperature is too high. The alarm light will still be on;
3. The function of the water temperature warning light: remind the water temperature when the engine is working, prevent the engine from being damaged due to excessive high temperature, and play a warning role.

What is the reason for the beating of the water temperature gauge? Because:

Check whether the water temperature sensor is faulty. The Buick Regal water temperature gauge jumps up and down because the plug of the water temperature sensor is loose or the water temperature sensor is faulty.

The water temperature gauge is displayed in digital form, 50-130 degrees Celsius, and the normal temperature is around 90 degrees. The water temperature gauge alarm is to remind the owner that the vehicle water temperature is too high and needs to be stopped for rest. If the vehicle continues to drive, the engine will be scrapped.

How to solve the water and oil temperature light on the car dashboard?
The solution to the car's water temperature gauge is bright:

1. When the water temperature warning light is on, you should stop the vehicle and check it. It should be noted that parking does not mean turning off the engine. Let the engine continue to run at idling speed, and open the engine cover to dissipate heat.

2. After parking the car, open the engine cover and look at the auxiliary water tank Is the antifreeze level normal? If the antifreeze is too low, you can add antifreeze. If there is no antifreeze, you can use mineral water to replace it temporarily, but you need to replace it with new antifreeze afterwards. For most models, the water pump of the cooling system is basically driven by the engine. After the engine is turned off, the water pump will also stop at the same time, and the antifreeze cannot continue to circulate. At this time, all parts of the engine are basically maintained at high temperature. If effective cooling is not obtained, the engine may be damaged.
