Hello dear! Open the hood, in the lower left corner of the engine compartment, that is, in the lower left corner of the tank, there are two very thick water pipes, one in the upper right corner of the radiator and one in the lower right corner of the radiator. At the bottom of one of the pipes below is a plastic Crucifixion.

It's very big, the screws are facing outward, if you want to change it, you must remove the left front fog lamp grille, the fog lamp grille pulls out hard, you can see the screw, you use a screwdriver to unscrew the plastic screws, don't unscrew it, the antifreeze will leak out. When replacing it, after the antifreeze leaks, start it to drain the remaining liquid. Add new antifreeze.

I hope it can help you, please set it as! Thank you!

Hello, because the circulating water is not only available in the engine, but also in the air conditioner and heater. Generally, if the antifreeze is replaced, if it is the same ether or ethylene glycol, there is no need to consider the problem of cleaning. If the replacement antifreeze is different, you can add 1-2 times of water purification after putting the old antifreeze and then add a new antifreeze, so that the original antifreeze content can be minimized.

Even if the water is not clean, it has no effect because all antifreeze has water in it. After replacing the anti-new freeze, pay attention to the specific gravity of the detection. It's not good to be too high or too low.

One more point. Generally, the car should be heated and drained, and there is a water release switch under the water tank and the cylinder body, (if the cylinder body is not available, the relevant pipeline can be disassembled for ventilation) It is best to let the front of the car be slightly lower. At the same time, it can also run the engine without water, and the time should not exceed one minute.

In this way, the water in the system can be basically drained.

As long as the return pipe of the water tank is disconnected, the old antifreeze of the cooling system can be completely emptied, and the specific operation steps for replacing the antifreeze are as follows:

1. Stand Dongfeng Xiaokang K17 to reduce the water temperature to normal temperature.

2. Slowly unscrew the lid of the water tank to release the internal pressure.

3. Disconnect the return pipe of the water tank to drain the antifreeze, and then connect it.

4. Fill the water tank with antifreeze until it is full.

5. Run the engine until the water temperature rises to 90 degrees.

6. Turn off the engine and let it stand until the water temperature drops to normal temperature.

7. Open the lid of the water tank to release the internal pressure.

8. Fill up with antifreeze to complete the operation.

You can't put the old ones in there, because there's still a little bit in the engine! Remove the plastic plug at the bottom of the water tank, put it without water, start it for 10 seconds, then turn off the ignition, put the plug up and add antifreeze!

But see that the tree is not very far from the building.

The specific manipulation steps are as follows:

1. Twist the car key of Dongfeng Xiaokang C37 and turn off the engine.

Summary. Hello, the water temperature of the car is high, there are several factors that affect it. The first one is the thermostat, which does not turn on.

The second is that the tank electronic fan is not working. The third is a clogged tank. The fourth is a damaged water pump.

The fifth is that the engine has less water. The water temperature is generally high due to damage to the thermostat. The water temperature is high, so it is recommended that you do not drive to avoid damage to the high temperature of the car engine.

The car goes to the car repair shop to replace the thermostat can replace the thermostat in about 120 yuan in different areas, **there will be differences, you can also consult your local car repair shop for details, you should have air in this line, need to remove the water temperature sensor to exhaust the air to see if I hope my can help you!

Seepage car to the car repair shop to replace the thermostat can replace the thermostat** in the area of about 120 yuan, **there will be differences, you can also consult your local car repair shop for details, you should have air in this line, need to remove the water temperature sensor to exhaust the air to see, I hope my can help you!

Hello, the engine water tank exhaust air, 1, this is no air exhaust, he started the self-Na He dynamic grinding rolling circulation air exhaust air, you can disassemble the warm air water pipe to exhaust the air, and wait for the warm air water tank position to flow out of the eliminator, the warm air water pipe can also be installed, 2, and then start the car, wait for the fan to work, the temperature of the upper and lower water pipes is the same, the fan heat dissipation is hot air, this is no problem, it is normal.

1. Dongfeng Xiaokang C32 plus coolant is located in the engine compartment. Coolant is also called antifreeze, open the hood, you can see a hungry white container, that is, the expansion pot, there is a mouth on the expansion pot, that is, the filling port of antifreeze, the antifreeze filled into the dust expansion pot, will be replenished to the cooling system through the refill tube.

2. Antifreeze coolant, as the name suggests, in addition to the cooling function, can also prevent condensation at low temperature to ensure normal operation.

Antifreeze can freeze at zero degrees Celsius and won't damage the engine, for example, if you freeze a soda for a long time, the bottle will break, and the same goes for the engine. Secondly, antifreeze has the same effect as a water tank treasure to prevent corrosion and rust of the engine waterway and water tank.

Reasons and steps for changing antifreeze square air:

1. There are leaking places in the cooling system, such as water pumps, water tanks, etc.

2. When filling antifreeze, there is air in the antifreeze pipeline, and after the air is discharged, the level of antifreeze will drop.

3. The engine boils water, if the engine gasket is broken, the antifreeze will be burned, and the cylinder gasket can be replaced.

4. The high water temperature of the cooling system causes the pot to boil, and the antifreeze is sprayed out, and the reason for the high water temperature needs to be checked.

The presence of air may cause:

1 Local high temperatures, also known as boil-and-boil 2 Cavitation is a damaging device similar to corrosion.

Evacuation method with attention.

1 Fill a part of antifreeze first, and then slowly fill to give the bubbles enough time to come out 2 After filling up, test run for a while, and wait for the bubbles to come out before filling up.

Hope it helps.

If there is air in the cooling system, it is easy to cause water backflow when the pot is boiled.

There are bleed valves on the engine cooling system, you can check the maintenance manual yourself.

There are many ways to drain water, and the more standardized operation is to lift the car and unscrew the drain screw at the bottom, so that the antifreeze can be discharged from this drain screw hole. There is also a method that is not very standardized, but very practical and used by most repair shops is to directly pull out the "sewer pipe", which has the advantage of releasing water relatively quickly and does not need to lift the frame to jack up the vehicle. In this way, the water will be drained faster and more thoroughly than with the drain screw.

However, no matter which way you drain the water, it is impossible to clean all the antifreeze in the car, and there will still be a lot of antifreeze left in the engine water jacket, condenser, etc. Therefore, it is recommended that when changing antifreeze, try to choose the antifreeze specified by the original factory, and be sure to avoid the mixing of different brands and models of antifreeze.

Of course, if you decide to change the brand of antifreeze, you will need to flush the cooling system after the antifreeze has been completely discharged. The method of flushing is to fill the reservoir with a steady stream of clean water, while keeping the drain open to let the water flow smoothly from the bottom, and in the process of flushing, it is necessary to start the vehicle briefly for about 3-5 minutes, and turn on the warm air, and the clean water must be circulated. The purpose of this is to make all the old antifreeze in the car flow out, and the water to be drained becomes colorless clean water, which means that your flushing work is complete.

When you put it, it is best to turn on the air conditioner to the maximum, start and get out of the car, if there are impurities, it is estimated that you will have to clean it repeatedly.
