What to do if the water temperature of the vehicle is too high in summer

When we encounter an alarm of high water temperature, we should first slow down, and then drive the car to the side of the road, do not rush to turn off the engine, because the water temperature is too high, which will cause the temperature of the piston, steel wall, cylinder, crankshaft, etc. to be too high, and the oil will become thinner and lose its lubrication. If the ignition is turned off at this time, the parts are in a state of expansion, and the gap between the accessories is very small, which will cause some soft metals to fall off after the shutdown, and some will even cause the cylinder to stick. Therefore, do not turn off the heat immediately after you find that the pot is boiling, but keep idling for the time being to try to cool down.

Do not pour cold water on the engine when cooling down, as this may cause the engine block to burst due to quenching. The correct way is: put on gloves, add a multi-folded damp cloth to the water tank cover, gently unscrew a small slit in the water tank cover, wait for the water vapor to slowly drain out, and after the water tank pressure drops, add cold water or antifreeze.

If the water temperature in the car is too high, it is recommended to check whether the antifreeze is missing or needs to be replaced.

Hello, if the water temperature of the vehicle does not alarm, there is no problem, the water temperature of the air conditioner will be higher in summer, if the alarm needs to be checked.

Hello, this advice should not be opened again, check if the antifreeze is missing, or if there is a problem with the thermostat.

Hello, this should first be caused by the lack of coolant, followed by poor fan heat dissipation or damage to the cylinder head gasket, which should be solved in a targeted manner.

In this case, you need to see if it is caused by the lack of antifreeze, and if you check it less, you need to replenish it in time.

It is advisable to check if the antifreeze is missing, and if there is no alarm, there is no problem.

In your case, you need to see if it is caused by the lack of antifreeze, and you need to replenish it in time.

Caused by high water temperature, it may be that the thermostat cannot be opened, the temperature control switch is not accurate, the electronic fan motor is faulty, and the water tank condenser is faulty.

What should I do if the water temperature in my car is too high?

1. First of all, after finding that the water temperature is too high and stopping to the side, it should not be turned off immediately, because there are many reasons for the high water temperature, but there is probably only one fault each time, if all other functions are turned off, the water temperature will be too high, damaging the engine, the accurate approach should be to idle the park, open the hood, turn on the heater, dissipate heat as soon as possible, and pay attention to parking in a cool place.

2. Next, we have to check whether the coolant is sufficient, this situation is likely to be that the owner usually does not care about forgetting to add it in time, and it should be noted that the owner must choose the same brand and model of product when adding coolant, otherwise it may cause chemical reaction due to different components and lead to the failure of antifreeze.

3. Then, we are looking at whether the cooling fan is running normally, and the failure of the cooling fan will cause the heat generated in the car engine at high speeds to be transferred to the antifreeze and not be dissipated in time, resulting in an increase in the temperature of the antifreeze. If the fan is stuck or the insurance is burned, you can solve it as soon as possible after the power failure, if it is a line problem, it can only be handed over to the professionals of the 4S shop to overhaul.

Extended Information: Car Radiator Function.

The function of the cooling system is to dissipate excess and useless heat from the engine, so that the engine can operate at normal temperature at all speeds or driving conditions.

The water tank is the heat exchanger of a water-cooled engine, which is cooled by air convection to maintain the normal operating temperature of the engine. Once the cooling water of the engine in the water tank boils and vaporizes and expands due to high temperature, and the pressure exceeds the set value, the pressure will be released from the water tank cover (a), resulting in a decrease in cooling water and preventing the cooling system pipeline from bursting.

When driving, you should pay attention to whether the engine cooling water temperature gauge pointer on the dashboard is normal. In addition, if the engine cooling fan fails and the water temperature of the engine cooling finger bend rises or the cooling system pipeline leaks, the cooling water may also be reduced.

Solutions to high water temperature:

1. Check whether the water tank is leaking, open the water tank to see if the water surface height is below min, if the water level is very low, it is likely to be water leakage. Add water, open the exhaust screw near the engine to exhaust, and check for water leakage. The presence of gas in the tank can also cause the water temperature to be high.

Water leakage is generally a cool car leakage, so check after the hot car is cooled, pay attention to see if there is a leak in the warm air and water pipe joint leading to the driver's cab, and look at the ground under the car when you get up in the morning when the leakage is large. If there is no leakage, but the water gradually falls below the lowest point after a week or half a month of filling up the water, then there is another possibility that the cylinder gasket is leaking and the water seeps into the engine and consumes. Open the oil filler to see if there is white foam and bubbles, see if there is oil in the water tank cap, and see if there are white water droplets on the oil dipstick.

If so, water seeps in. The cylinder gasket needs to be replaced.

2. Change the water temperature sensor. If you don't boil the pot, it just shows that the water temperature is high, and it may also be caused by the inaccurate water temperature sensor. Change the water temperature sensor.

3. Change the thermostat. After the water temperature reaches 90 degrees, open the cabin cover and touch the water pipe near the engine to heat (be careful of hot hands), the water tank is not hot, that is, the water is not circulating. It's hot on both sides. Otherwise, the thermostat should be replaced.

4. Water change pump. The water pump is the most expensive, so you have to change it last. I have seen with my own eyes that there are a lot of rubber strips twisted in the pump of my car, and the pump is not working well, and the water cannot be circulated, causing the water temperature to rise rapidly.

This necessitates the replacement of the pump.

What should I do when I suddenly find that the water temperature is too high or even "boiling" while driving? Pull over, but don't turn off the engine right away! Because the coolant temperature is already high and the cooling capacity has reached its limit, if the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft).

Of course, if it is an electric water pump engine, it will be good.

When the water temperature is high, avoid turning off the fire immediately.

When the water temperature of the vehicle is too high, the owner must not turn off the engine immediately. For most models, the water pump for the cooling system is engine-driven.

After the ignition is turned off, the water pump will also stop at the same time, and the coolant can not continue to circulate, and all parts of the engine are maintained at a high temperature, and if it is not effectively cooled, the engine may be damaged.

There are many reasons for high water temperatures.

The thermostat is damaged.

The water pump is damaged. Lack of water can cause high temperatures.

After the high temperature, turn on the heater to cool down.

Do not turn off the heat. Idle operation.

Flameout will cause the cylinder to burst.

Drive at a low speed when the water temperature is lowered.

Do not exceed 2000 rpm.

In this way, the acorn dates pay attention to the water temperature.

You can rush to the repair station and slowly drive to the repair station beam to dismantle.

This saves on towing fees.

Add antifreeze.

It can prevent freezing and cooling.

If the water temperature is high, it is recommended to check two points, the first is whether the front cooling tank is dirty? The second is that there will be problems with the thermostat.
