What to do if the engine grinds through the rainbow cover and the water temperature is too high

Hello! If the vehicle's water tank is not properly handled in ordinary driving, it is very easy to "boil the pot" phenomenon. Either white water vapor comes out of the engine cover, or when the water thermometer needle rises rapidly to the high temperature "H" mark, it means that the engine temperature is too high.

It is mainly caused by insufficient water in the water tank, water leakage, or the water tank fan does not run. Here's how to deal with it!

Step 1: Find a safe place to park immediately, but never turn off the engine immediately. Keep the engine idling to continue dissipating heat, while opening the hood to increase the rate of dissipation.

Note: In case of high water temperature or even boiling:

1. Do not try to continue driving, so as not to cause major accidents.

2. Do not try to open the lid of the water tank, otherwise it is very likely that hot liquid will spray out and cause scalding.

3. Do not pour cold water on the engine block and cylinder head, which is likely to cause the cylinder block to burst due to quenching.

Step 2: After a period of time, check for water leaks under the car.

Step 3: Wait until the water thermometer pointer drops to the appropriate temperature position, then turn off the engine.

Step 4: Wrap the water tank cover with a wet towel, slowly open the first switch, and after the water vapor pressure is released, open the water tank cover completely, check the water quantity and quality in the water tank, and whether the fan belt is abnormal. If the amount of water is insufficient, you should slowly add water to the vicinity of the highest marking.

Note: If the water tank is leaking or the fan belt is loose or broken, you can call the towing company ** and wait for the trailer rescue. If necessary, you can also wait for the engine to cool down completely, and then drive the car to the service shop for maintenance at low speed.

Remember, you can't drive at normal speed, as there is a high risk of permanent damage to the engine.

Hope it helps, hope, thank you!

1. When the engine temperature is too high, you can use your hand to touch the temperature of the upper water pipe and the lower pipe to judge, if the temperature difference between the two water pipes is large, you can judge that the thermostat is not working, if you can't buy accessories on the way, you can remove the thermostat for emergency, and replace it immediately after going home.

2. If there is air in the cooling system, it will form air resistance, which will make the cooling water circulate poorly, resulting in high engine temperature. The following methods can be used to deflate: let the engine run at high speed, gently unscrew the water tank cover until the gas is just released, at this time, some cooling water will flow out with the gas, and so on many times until you feel that the gas is exhausted (at this time, touch the upper and lower pipes with your hands, and the temperature will be significantly different from before the gas).

After troubleshooting, the cooling water should be replenished in time.

3. If the vehicle is driving on a dirt road or muddy road for a long time, there will be some dirt adhering to the radiator, which will affect the heat dissipation effect over time and cause the water temperature to be too high. In this case, you can blow the radiator grid with compressed air first.

4. If the temperature is too high or the temperature indicator light keeps flashing, stop to check whether the cooling water of the water tank is normal, and whether there is leakage at the water tank and water pipe. If no abnormality is found through inspection, you can continue driving after replenishing the cooling water. If the temperature is still too high after driving a certain distance, and the cooling water is reduced after stopping for inspection, this is mostly due to the loss of sand hole or perforation in the water jacket of the cylinder block.

5. In the process of driving, if the water temperature is too high, it must not be washed with cold water, so that the cylinder may break; You should also not rush to open the lid of the water tank, so as not to hurt people with boiling hot water. Turn off the heat and wait for about 20 minutes before opening the lid of the water tank and adding cold water for emergency.

Cars can also have a high fever just like people, what should I do if the car is hot?

The normal working temperature of the water-cooled engine should be 80-90 degrees. The temperature of the engine is taken as an example of the Jiefang CA10B car, and the engine temperature can be adjusted by pulling out (i.e., opening) or pushing out (i.e., opening and closing) the louver joystick in the cab according to the temperature of the engine, changing the amount of air entering the radiator.

The normal water temperature of a car's engine is 85 95, and the water temperature can be controlled by opening the shutter joystick in the cab to allow air to circulate through the radiator.

The cylinder liner needs to be replaced after the cylinder is pulled.

There are many reasons why the water temperature of the engine is too high, such as too many dirty items on the surface of the cooling water tank, damaged electronic fans behind the cooling water tank, and the antifreeze is not replaced for a long time.

The engine of the car is water-cooled, and the water-cooled engine relies on antifreeze to continuously circulate heat in the engine.

Antifreeze has two circulation paths within the engine, one for the large cycle and the other for the small cycle.

In the case of the engine just starting, the antifreeze will implement a small circulation, at this time the antifreeze will not pass through the heat dissipation tank, which is conducive to the rapid heating of the engine.

When the engine reaches its normal operating temperature, the antifreeze is dissipated through the radiator water tank, which keeps the engine within the normal operating temperature range.

The freezing point will rise and the boiling point will fall when the antifreeze is used for a long time, so it is natural that the antifreeze needs to be replaced regularly.

If it is not replaced for a long time, it will affect the normal operation of the engine.

When replacing antifreeze, be sure to clean the old antifreeze inside the cooling system.

The high water temperature means that there is a problem with the engine's cooling system.

To put it simply, the internal operating temperature of the engine is 800 to 1000, if the cooling system does not bring away the excess heat. The internal pistons, cylinder heads, sealing rings, etc. will be burned out. Even if it's metal, there is a temperature that I can't endure.

High temperature may cause the cylinder to be pulled, and there is also a high level, low speed, may also pull the cylinder.

Pulling the cylinder is not a good thing, and it may cause the piston, rocker arm, and other cylinder internal parts to wear faster, or directly damaged. Pay for one's whistle. These things are all special metals, special methods such as casting, manufacturing. It's quite expensive to change one.

The engine was pulled and only overhauled.

This can only be overhauled the engine.

If the water temperature is too high, it is commonly known as "boiling the pot". "Boiling" can cause deformation or even damage to the cylinder head and block.

In summer, when the temperature is high, it becomes difficult to dissipate heat from the water tank, the water temperature of the engine will rise to varying degrees, and the hose is more likely to soften and leak cooling water, so it is common for the water temperature to be too high or even boil during driving. The normal engine water temperature should be constant between 85-95 degrees Celsius, when the water temperature is too low, the fuel enters the cylinder can not be atomized well, the power and economy are not good, and the matching gap between the parts is too large at low temperature, and the noise and vibration will be larger. When the water temperature is too high, the viscosity of the oil will become thinner, the lubrication strength will decrease, and at the same time, the high-speed moving parts such as the piston and valve are more likely to deform, resulting in engine weakness.

In severe cases, the expansion and deformation of the piston will strain the cylinder, the crankshaft bearing dissolution and lock the crankshaft, etc., the consequences are unimaginable. Therefore, if the water temperature gauge is close to the red zone, or if the water temperature warning light is on, you should immediately pull over and turn off the engine for inspection.

Go to the auto repair department and let the repairman take a look, and leave the professional things to the professional people to do.

If the water temperature of the truck crane engine is too high, it should stop working immediately and find out the cause and solve it in time

Check whether the engine waterway and water tank are blocked, and replace the antifreeze of the truck crane regularly, it should be noted that the liquid concentration of the truck crane cooling system cannot exceed the standard, otherwise the water temperature will rise;

2.Check whether the load of the truck crane engine is too large, which affects the heat dissipation performance of the cooling system, excessive filling of air conditioning refrigerant and air conditioning refrigeration lubricating oil, or blockage of the air conditioning condenser, etc., will increase the load;

Check whether the temperature difference between the upper and lower water pipes of the water tank is within the normal range, check whether it is caused by the speed of the water pump, and the return pipe on the antifreeze storage tank is blocked or the water return is not smooth, which will also affect the water temperature rise;

If the cooling system fails, check whether the oil dipstick scale is at the normal value;

When carrying out fault maintenance, do not blindly disassemble the parts, so as not to cause the loss of spare parts, and usually carry out regular maintenance, so as to find the fault in time and prolong the service life.

This glitch is easily forgotten. This fault is caused by burning engine oil or too little engine oil (which may be caused by burning engine oil). The main role of the engine's oil is:

Lubrication, sealing, heat dissipation. When there is less oil, the lubrication and heat dissipation effect is poor. It can cause the water temperature to rise rapidly.
