[Winter is coming] I replace fresh blood for my car
KellyDewey 
7 Time flies, and it has been nearly three and a half years since the car was bought unwittingly. My little Ai accompanied me to many places without complaining, and I never treated her badly. I changed the oil, maintained and replenished all kinds of oil and water on time. All kinds of routine maintenance, inspection never left behind (I did all these myself). Now think about it, winter is coming, the antifreeze on my car should be changed. although it is the antifreeze of the original car, the mileage is not much, but over time, the freezing point of antifreeze will be much lower. The manual also indicates that 40,000 kilometers of antifreeze will be replaced in 2 years. In addition, although the weather in the north can not be compared with that in Northeast China, it is also very cold. Get a few bottles of antifreeze from the original car, dry it out, find a place, get tools, and get to work!![]()

Stop the car in position. Open the cover. Since you don’t need a lift or anything, you can change it anywhere. It’s simple. Qualified students can find a trench or something that is more convenient to change.
Engine room internal structure, ready to begin.
Remove the air filter shell first. In the way, it is more convenient to unscrew the water release screw.
The position of the discharge screw can be seen vaguely, which will be specified later.
Fixed wire harness of the tie clip, this thing is still a conscience. Some cars break down when they take scissors or change cones.
Be careful! The key point is that the antifreeze had better be replaced by a hot car, and the upper and lower water pipes should be heated up, not the water temperature. After the thermostat is turned on, the upper and lower pipes of the engine will have the same temperature, so that the waste antifreeze of the engine body can be better discharged. There are also matters needing attention: when twisting the kettle lid, let it cool naturally for a few minutes after the water temperature comes up completely, and do not screw the kettle lid immediately. Put on a wet towel when twisting, press and rotate hard to prevent the pressure inside the kettle from overflowing antifreeze and causing scald.
This is the discharge outlet. Note: you can not unscrew the screw counterclockwise until the top of the kettle lid is completely unscrewed, so that the waste antifreeze can flow out.
This is the discharge screw, note: when screwing, there is a sink on the screw body, be careful not to get burned, and don’t lose the rubber ring above.
Because Xiao Ai has a guard plate at the bottom, he is afraid of the flow guard board, and he can only come up with a silly way to accumulate dust over a long time. Qualified students can cover the upper kettle mouth with an air pump to pump air at the same time. This is more conducive to the discharge of antifreeze liquid inside the cylinder. If there is no condition, you can blow air into the kettle with your mouth. Of course, I belong to the latter. Ha.
Do you see the dirty mud inside the pot? It’s too muddy.
Half a basin of waste liquid gives off an unpleasant smell.
When there is no antifreeze coming out of the lower discharge port, you can screw on the discharge screw and wipe the screws with paper (in preparation for checking whether the liquid is leaking later). After that, you can add the fresh antifreeze to the pot, be careful not to fill it too quickly or too full.
When adding to the engraving position, pinch the upper pipe and the lower sewer pipe back and forth, and then when the water level is not falling at all, start the vehicle, and after the water level drops, add antifreeze to the engraving position in time. During the period, you can pinch the water pipe and the sewer pipe, which can carry the throttle to keep it stable at about 1500-2000. If the water level does not fall, screw on the kettle cover and tighten it to raise the water temperature. During the period, you should often touch the upper and lower water pipes to see if the temperature of the two pipes has reached a constant. If the fan rotates and the sewer is really cold, it means that there is gas inside or the antifreeze needs less exhaust, then the vehicle should be flameout immediately. After cooling, fill the kettle with antifreeze and reignite to complete the above steps.
Warm air hose, hot hands
Everything is fine. You can pick up the car.
The above are my steps to change the antifreeze this time. If there is any improper operation, please point out one by one. In addition, we must pay attention to the points for attention mentioned above. After the change, I feel that the temperature of the water comes up a little faster than before. I don’t know if it’s psychological.![]()
