There is a LOW COOLANT on the dashboard of the old Buick, what does it mean?

Low Coolant isBuickcar in the engineCoolantAn indicator light that only illuminates when the liquid level is too low.

When the indicator light is on, it means that the engine coolant is running low and the coolant should be replenished in time. Under normal circumstances, the coolant circulates through the engine water jacket, cooling system and air conditioning heating system without significant reduction. When the low coolant indicator light is on, it is likely that there is a leak in the cooling system pipes.

Coolant is very important for the engine

The correct use of coolant can play the role of anti-corrosion, anti-cavitation leakage, anti-radiator boiling, anti-scale and anti-freezing, etc., which can make the cooling system always in the best working condition and ensure the normal working temperature of the engine. If you do not pay attention to it in use, it will seriously affect the normal performance and life of the engine.

For conventional engines, the coolant temperature value that can ensure the normal operation of the engine is 80 90, but the engine, mechanical heat load.

Larger, higher frictional heat, so the requirement for the normal operating temperature of the coolant has been increased to 95 105. And pay attention to the continuity of coolant use, the view that only needs to be used in winter is wrong, only know the anti-freezing function of coolant, and ignore the anti-corrosion, anti-boiling, anti-scale and other functions of coolant.

The above content refers to Encyclopedia - Coolant.

First of all, lowtire is the meaning of low pressure, and lowtire yellow light is common in Buick series models, to be precise, it is a low tire pressure warning light, equivalent to the current tire pressure monitoring, if the indicator light is on in driving, do not panic, slow down and pull over, stop to check the four tire pressure.

If you have a simple inflator on your car, you can test and inflate each tire yourself. If you don't have a simple inflatable tool, you can drive slowly and find the nearest repair shop to inflate. Note that after restoring the normal air pressure of the tire, the indicator light will not be removed from the dashboard and needs to be removed manually.

At this time, open the safety cover from the right side of the co-pilot, you will see a red reset button, at this time to turn on the ignition switch, that is, the position of the instrument light, press and hold reset for 6 seconds, lowtire yellow light will be eliminated naturally.

That light is a test light with too low coolant, it may be that the water in the tank is less or to the lowest line, it is a water level sensor installed on the water tank, in the morning, you can open the water tank cover to see if the water in the tank is less (if there is no less) or it may be that the water level sensor is broken, (Buick's water tank cover is a little difficult to open, you have to press the water tank cover down and then slowly unscrew it.) ）

The outdoor temperature is too low, and the antifreeze liquid level is close to the low bottom line, remind to add antifreeze or replace the antifreeze, but sometimes it is due to a false alarm due to the cold, especially in the morning when the temperature is too low in winter, you can visually inspect it and then decide whether you need to replenish it.

Low coolant, which may mean low water temperature.

On the contrary, the coolant is not enough, and the engine temperature is too high.

The coolant level is too low and water needs to be added.

It is Buick's tire pressure warning indicator. When the indicator light is on, carefully check the air pressure on the four wheels of the car.

2.Tire pressure refers to the air pressure inside the tire. The level of tire pressure plays a vital role in the performance and power of the car.

3.Buick's car brands include Encora, Excelle, Yinglang, Langyue and Longwill.

4.Take the Encora, for example: the car measures 4,295 mm, 1,798 mm, 1,607 mm in height, and has a wheelbase of 2,570 mm.

It is a five-door, five-seater SUV with a 6-speed automatic manual transmission and a top speed of 180 kmh.

This is the engine coolant insufficient reminder that forcibly starting the engine will cause poor heat dissipation of the engine, and in severe cases, it will damage the engine.

It is recommended to add coolant before driving!

If you lack coolant, go to the auto parts city and buy a bottle or two to inject it to recover.

Lack of antifreeze, the engine cooling system should be checked.

The tire pressure monitoring indicator is always on, and there are usually four situations:

1. The tire pressure monitoring light is on due to the tire being punctured.

This situation is usually very slow air leakage, for a while can not find out which tire is it, at this time you can use the tire pressure gauge to measure, front, rear, if there is a lack of air, make up, and then observe the tire pressure warning light, if a few days later and on, it may be necessary to pick up the tire to check. 4S shop, the usual treatment of the maintenance personnel is to adjust the pressure of the two front tires, adjust the pressure of the rear tires, and then cut off the tire pressure alarm, and let us run another day to see, if you don't call the police again, there will be no problem, and then the police may be pricked, you need to go to the 4S shop again, let them help check and check.

2. The tire pressure monitoring light is on, sometimes the tire pressure is too high.

Generally, the international GBT 2978-2008 standard stipulates that the inflation pressure of car tires meets the requirements of Table 1-Table 15

Standard tires:; Reinforced tires:; Maximum air pressure: should not be greater than. Therefore, when there are tires that exceed them, the tire pressure monitoring light will also be triggered, and 3. The tire pressure monitoring light will be on due to low tire pressure driving time for too long.

This situation usually occurs when the tire pressure of a tire is too low, and the tire temperature rises due to high-speed operation, which in turn causes the tire pressure to rise.

4. The tire pressure monitoring light is on due to the low tire pressure that has not been refilled for a long time.

When the air pressure is lower than the bottom, the tire pressure monitoring light is on, so you should usually do a check to see if the tire pressure detector is normal. When the car is in trouble, if the tire pressure monitor does not alarm in time, it is a problem with the tire pressure monitor; If the ignition switch is on start, the indicator light point and the TPMS indicator light will be on at the same time for 2s and then turn off. In this case, either the original receiver of the vehicle has not been learned, or the receiver controller has been replaced, and the receiver controller has not been learned.

You can go to the 4S store and ask professionals to use handheld learning tools to re-obtain all tire sensor IDs and bind the receiving controllers.
