Is the original car coolant replaced once in ten years or 200,000 kilometers?

No. Antifreeze is generally valid for two years. Expired antifreeze can cause corrosion of the cylinder block and even serious damage to the engine. In addition, the freezing point of antifreeze is generally around -25, and if you go to a colder place, you need to change to an antifreeze with a lower freezing point.

The correct use of coolant can play the role of anti-corrosion, anti-cavitation leakage, anti-radiator boiling, anti-scale and anti-freezing, etc., which can make the cooling system always in the best working condition and ensure the normal working temperature of the engine. If you do not pay attention to it in use, it will seriously affect the normal performance and life of the engine, so special attention should be paid in use.

To judge when to change the coolant, the first way is to look at the instructions for the use of the coolant, and there will be a description of the product; Generally, the coolant is added to the water tank, and its service life is less than 2 years. Second, you can also operate it yourself, open the water tank, check the turbidity of the liquid in the box, if it is already very turbid, and there are floating objects that are corroded by the metal of the box, it is recommended to change it.

However, traditional coolants: water and aqueous antifreeze cannot meet the congenital defects of engine heat dissipation

1. The water will freeze at 0, and the pot will boil at 100. Ice can inflate the engine's water tank and cylinder block, and boiling the pot can overheat the engine until it causes paralysis.

2. When the engine temperature reaches more than 80, water bubbles should begin to produce on the cylinder wall. Water bubbles form a bubble barrier layer on the cylinder surface, preventing heat from escaping from the engine. Water bubbles are endlessly formed and burst on the metal surface of the engine block, and the cylinder block is lost in a dripping effect This is cavitation.

3. The local temperature inside the engine is too high, and the pre-ignition and detonation tendency increases, which increases the vibration and noise, greatly reduces the performance and efficiency of the engine, and forms no water and fuel consumption.

4. Under the action of electrolyte, electrochemical corrosion occurs and rust and scale are produced, which aggravates the aging rate of the cooling system and reduces the heat dissipation performance.

5. When the engine temperature reaches more than 80, the water vapor, water bubbles and water body expand, which increases the internal pressure of the cooling system. In this way, it not only catalyzes the aging rate of the cooling system, but also makes it impossible to ensure the speed required for normal heat dissipation due to corrosion. Therefore, the heat dissipation defects of aqueous antifreeze are summarized as:

The heat dissipation performance is limited, and the overheated vertex cannot be suppressed; The engine gradually ages, so that the engine heat generation increases unabated; The cooling system gradually ages, so that the heat dissipation capacity is reduced but not increased.

It is recommended to use the latest product of coolant replacement: Huibang cooling oil, Huibang cooling oil can effectively solve the above problems and better maintain the performance of the engine. There is also the effect of saving fuel, more environmentally friendly! 500,000 km maintenance-free!

Generally, it is replaced once every 2 years or 60,000 kilometers, and the antifreeze can be appropriately replaced in the cold winter.

Hello, yes, the instructions say so.

When Honda Fengfan opened the hood while changing the coolant, he could see that there were two holes in one trim plate on the front of the car, one for the water tank and the other for the auxiliary kettle. Find the location of the tank, unscrew the lid of the refrigerant storage tank, and pour in the refrigerant so that the liquid level is between the two scale marks.

The ** of Honda Sail Sealing Antifreeze is around 40 per liter. Car owners can add antifreeze at the top below the tick mark, according to the actual situation. The full name of antifreeze should be antifreeze coolant, which means antifreeze coolant.

Antifreeze prevents the coolant from freezing the engine block or cylinder head when the coolant is shut down in the cold winter months. Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round. Antifreeze protects the components of the cooling system from corrosion, prevents fouling, avoids reducing heat dissipation from the radiator, and ensures that the engine can operate within the normal temperature range of the shedwheel.

When changing antifreeze, the first and most important step is to wait for the vehicle to cool down and not to change the antifreeze when the engine temperature is high. First, there is a risk of burns; Secondly, the release of antifreeze during the "hot car" can also affect the cooling of the car.

First of all, it must be put in the case of a hot car, otherwise the thermostat will automatically turn off, and the antifreeze in the engine will not be discharged.

The place where the water is put is under the inside of the tank. There is a bolt, butterfly-shaped, which can be twisted by hand, and the antifreeze is drained after unscrewing (open the tank lid first).

Then, after putting it clean, tighten the bolts. Add antifreeze to the main opening on the water tank, patiently and slowly, until it is full. Wait a while for the liquid level to stop dropping.

Then start the engine and idle for a while (the purpose is to heat the antifreeze) to see if the liquid level drops, and continue to make up for it. Until it doesn't fall.

Then, turn on the air conditioner to the hottest (no need to start AC), turn on the fan 1 gear, wait for the warm air to blow out, bang the throttle, let the engine speed slowly rise to 2000 2500 rpm, repeat many times (this step is to drain the air in the cooling circulation system and the warm air circulation system, the engine speed is closely related to the speed of the water pump), replenish the antifreeze according to the situation, until the liquid level at the water tank mouth no longer drops, and then fill the antifreeze until the mouth is full. Then tighten the pressure cap.

Then it is to empty the liquid in the auxiliary tank (you can pump or remove it and pour it), and inject antifreeze into the middle of the min line and the max line. Then screw the sub tank cap.

Flameout. Wait for the car to cool down (come back in 2 hours). Observe the liquid level of the auxiliary water tank, and if it is below the min line, fill the auxiliary water tank with antifreeze (do not open the pressure cover of the main water tank afterwards, remember!). ) to close to the MAX line (don't exceed the limit, because the liquid level will rise after the hot car).

Observe again in a few days. Make sure the liquid level is normal. If the liquid level drops too much and you need to replenish the fluid frequently, check the tank and circulation system for leaks.

As long as the new car has not been hit, it does not involve changing the water tank, and the antifreeze runs for seven or eight years, and it is written very clearly on the hood, 1 year or 200,000 kilometers. If the water tank has been replaced, the antifreeze must have also been changed, and there is no need to change it again [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

There is a switch under the water tank of Hello Fengfan, turn on the switch, you can put the coolant out, turn off the switch after putting it down, open the water tank cover, and pour the coolant from the water tank cover! I hope my answer will help you and have a great time with your car! [If you have a problem with the car, ask the car master.]

Under normal circumstances, the coolant should be replaced every two years, and the replacement steps and precautions are as follows: (1) Release the coolant: first open the cover of the liquid storage (note that the radiator cover should be tightly sealed at this time), and unscrew the cylinder block and radiator drain switch, which should be carried out under the condition of low-speed heat of the engine.

2) Add new coolant. Car maintenance net Precautions: 1. After the coolant is exhausted, the cylinder block and radiator drain switch should be tightened.

2. Fill the specified coolant from the radiator filling port until the level of the coolant in the liquid storage tank reaches the specified "full". 3. At this time, cover the radiator cover, let the engine run to normal working temperature, stop the engine and turn off the engine to cool down to room temperature. 4. Observe the liquid level height of the storage tank and add it according to the situation until the engine is idling and there is no air in the storage tank.

1.First, stop for a while to prevent burns from antifreeze. The drain screws for antifreeze are at the bottom of the tank. Loosen it once found and see that the antifreeze does not flow out of the drain.

2.Hang the vehicle on the principle of letting clean water rinse the original antifreeze until the discharged water has no color. At this time, the old antifreeze is basically cleaned up.

3.After the clean water is discharged, install a drain valve and turn off the vehicle's engine. Fill the fill port with new antifreeze and keep the level between maximum and minimum. Accidentally adding more antifreeze did not close the state seepage system.

4.The engine is ignited again, because at idle, the air in the lines in the cooling system is further discharged, causing the antifreeze level to drop to a certain height.

5.Wait a few minutes. After the antifreeze level stops moving, add the antifreeze again between the two scales and the antifreeze will be replaced.

1.A syringe is a relatively simple tool. Open the filler and draw a portion of the antifreeze through the catheter.

2.There is a drain screw in the water pipe under the cooling fan. The sail spine loosens it to release excess liquid.

Don't try it lightly. There are certain risk factors for the large pressure in the tank, incorrect pressure relief, or no pressure relief. And the drain valves are not all exposed, some are hidden.

Even if it does, it is a big challenge to operate. )

The antifreeze of the Honda Fengfan should be changed about every two years or after a mileage of 40,000 kilometers.

The Honda Fengfan water tank is located at the front of the engine, between the condenser and the fan, and you can see the indication on the coolant addition port. When the hood is opened, you can see that there is a trim plate in front of the car with two holes, one for the water tank and the other for the auxiliary kettle. Find the location of the water tank, unscrew the lid of the refrigerant storage tank, pour in the refrigerant liquid, and the liquid level is between the two scale marks.

Remind car owners that when replacing antifreeze, the first and most important step is to wait for the vehicle to cool down, and never change the antifreeze when the engine is at a high temperature. First, there will be a risk of burns, and secondly, the release of antifreeze during the "hot car" will also affect the cooling of the vehicle.
