How to change car antifreeze

Question 1: How to replace the antifreeze in the car? There is a drain hole under the water tank. Just put it in. The most important thing is to add antifreeze. After adding the antifreeze, be sure to heat the car to allow the water tank to circulate widely, that is, the fan blows it. Hot air

Question 2: Can the car antifreeze be changed by myself? Yes, first increase the engine temperature. When the fan starts to rotate, the temperature is enough, and then turn off the engine.

Open the antifreeze drain valve under the car to drain the water. If possible, it is best to flush it again with high-pressure gas to let the antifreeze flow cleanly.

Afterwards, close the drain valve, add antifreeze, watch the kettle scale prompts, stop adding when it reaches half of the scale, start the vehicle, wait for the exhaust cycle, and check how much is missing before adding. Half of the scale is better.

Question 3: How to change car antifreeze? Hello, unscrew the water tank cover and water tank drain plug to drain the original coolant; remove the upper and lower water pipes and the heater water tank pipe to completely drain the original coolant Dry it, then clean the entire cooling system with clean water, and finally use a high-pressure air gun to blow out the water in the water pipe until there are no water droplets at the outlet of the water outlet. Install the water pipe, add new coolant, and fill the water tank. Start the car, continue to fill, squeeze the water pipe while filling until it can no longer be filled, then tighten the water tank cap and fill the auxiliary water bottle! Continue to heat the car until the upper and lower water pipes are equally hot and the fan is running. If there is any problem with the car, ask a car expert. Professional technicians from 4S stores can solve the problem in 10 minutes.

Question 4: Specific steps for changing antifreeze in a car. How to deflate the air after adding antifreeze 1. When the car is hot, unscrew the expansion tank cover and water tank cover. Pay attention to the hot air and put a piece of cloth on it. . 2. Remove the water pipe and sewer pipe on the side of the water tank, drain the water, and at the same time inflate the expansion tank to make the water flow as clean as possible.

3. After the water has finished flowing, install the sewer pipe.

4. Add antifreeze. The amount of antifreeze varies depending on the car model. Remember to vent the air after adding antifreeze.

Question 5: How to discharge the air when replacing car antifreeze. First, fill up the antifreeze, then take a taxi to see if the antifreeze has dropped. If it does, stay home until it stops. It means there is no air inside. The electronic fan has an independent sensor, etc. When the water temperature reaches a certain temperature, the water temperature sensor will automatically turn on. The water temperature sensor is usually installed at the water outlet, which is the engine water outlet. Some cars will have several sensors, but the engine water outlet must have air-borne heat conduction. If no water is added, the fan will continue to rotate.

Question 6: How can I change the antifreeze in my car? Just take it to a car repair shop to replace it.

Question 7: If you want to change the antifreeze yourself, how should you do it? It is best if the car is cold. Remove the water pipe and drain the antifreeze. Then rinse with clean water. Finally, add new antifreeze

Question 8: How to change car antifreeze yourself. It is recommended not to change it yourself. Your car cannot be lifted. If there is a problem with a car that is difficult to replace, ask a car expert. Professional technicians from 4S stores can solve the problem in 10 minutes.

Question 9: How to replace and refill automobile antifreeze. The engine cooling system must be carefully cleaned before refilling antifreeze. This is because descaling and cleaning agents are added to the antifreeze. If the engine cooling system is not carefully cleaned before use, after adding antifreeze directly, the original scale in the engine cooling system will fall off after contact with the antifreeze, causing the antifreeze to The fluid becomes turbid, thickened, even discolored and smelly. In serious cases, it blocks the water pipes and water channels or settles in the elbow joint at the bottom of the water tank, causing poor heat dissipation, preventing the antifreeze from circulating, and causing the engine temperature to be too high. In order to prevent these phenomena from happening, before filling the antifreeze, soak the water tank with 10% caustic soda aqueous solution for an hour, then drain the flushing fluid, and then flush it repeatedly with demineralized water 2-3 times to remove the original accumulation in the engine cooling system. Antifreeze can be added only after flushing. (2) Before adding antifreeze, check whether there is any leakage in the engine cooling system and eliminate it in time before using antifreeze. (3) It is prohibited to directly add antifreeze mother solution. Some drivers and repairmen think that the purer the antifreeze, the better, and the greater the ethylene glycol concentration, the better, and directly add the antifreeze mother solution. Not only does this fail to meet the freezing point requirements of the antifreeze, but some unexpected phenomena will occur. , such as antifreeze deterioration, high concentration, high density, increased low-temperature viscosity, and high engine temperature.

Therefore, when using antifreeze mother solution, it must be prepared as required and direct use is prohibited. (4) Regular inspections must be carried out during use of antifreeze. The validity period of antifreeze is generally 4 years, so there is continuity in use. In order to reduce waste, do not replace antifreeze at will after filling it. However, antifreeze in use should be inspected regularly. The antifreeze can be checked every year in conjunction with seasonal maintenance. The inspection should include freezing point inspection and specific gravity inspection. At the same time, the antifreeze in use should also be visually inspected. If the specific gravity increases, the antifreeze becomes thicker, the freezing point rises, and the antifreeze becomes turbid, deteriorates, smells, foams, etc., it should be promptly inspected. replace. (5) Antifreeze produced by different manufacturers cannot be mixed. Mixing can easily corrode the engine and water tank.

Question 10: How to replace the antifreeze in a family car? There is usually a drain switch at the bottom of the car water tank. You can take a closer look. If there really isn't. You can only remove the drain pipe to drain the water. After putting it away, reinstall it but it must be done with the car in a cold state.
