How much does Changan Star 2 need to change antifreeze?

Replace the antifreeze.

The dosage is about 5L.

There are standards for adding antifreeze, and too much or too little should not be added.

Too much antifreeze can cause spillage from the secondary jug of antifreeze. Because the vehicle's cooling system is under pressure when working. The secondary kettle lid is used to relieve the pressure in the cooling system, and if there is too much antifreeze, the antifreeze will overflow from this area.

Too much spillage is the result of a lack of antifreeze.

Too little antifreeze If there is no antifreeze, the engine temperature will continue to rise due to thermal expansion and contraction.

The internal parts of the engine will expand, which will cause the engine to pull the cylinder and not work. This is where the engine needs to be overhauled. When the engine is not working and the temperature is too low, antifreeze can prevent freezing, because the liquid is liquid and the volume will expand into a solid state, so it will freeze and crack the engine block.

If the engine block is cracked, the engine block needs to be replaced. That's why it's important to use antifreeze instead of water. Because antifreeze has a higher boiling point and freezing point than water.

Therefore, the antifreeze will not evaporate at high temperatures and will not freeze at low temperatures. So if the vehicle does not have antifreeze, it will cause engine damage.

After changing the water in the tank to antifreeze, it must be run for a few minutes, preferably to the temperature, so that the antifreeze in the tank can fully flow in the body waterway. There is no need to exhaust air.

Hello, according to your description, exhaust steps. Two places, one is the exhaust screw on the thermostat cover of the engine under the seat, which is not easy to operate personally. You can choose to exhaust from a thin tube next to the tank.

This tube is black, about the same thickness as the little thumb, the tube is inserted into the iron post at the jack position, pull it out, put the tube down, lower than the mouth of the water tank, and then add antifreeze, and then watch the tube flow out of the water after taking a taxi, and then add water while letting the tube flow out of the water, which is to let the engine water flow circulation to remove air. If the water continues to flow out without interruption, it means that there is no gas. At this time, tighten the water tank cover, and then wait for the water temperature to come up, to see if the electromagnetic fan is working normally, whether the heat dissipation exhaust air is hot air, if the hot air is normal, if it is a cool breeze, it means that there is still air inside.

You have to wait for the car to cool down before exhausting.

The specific operation steps of the Chang'an Star 2 after replacing the antifreeze are as follows:

1. Twist the key door to ST gear and start the engine.

2. Run the engine of Changan Star 2 until the water temperature rises to 90 degrees.

3. Turn off the car key of Changan Star 2 and turn off the engine.

4. Stand the engine of Changan Star 2 until the water temperature drops to room temperature.

5. Pull the forward flip switch.

6. Open the front flip.

7. Unscrew the lid of the small kettle to let go of the gas inside the cooling system.

8. Replenish the antifreeze to the max upper limit to complete the operation.

If you need to exhaust air, the specific operation steps of Chang'an Star second exhaust air are as follows:

1. Press the brake pedal of Chang'an Star II.

2. Twist the car key of Changan Star II and start the engine.

3. Run the engine of Chang'an Star II until the water temperature reaches 90 degrees.

4. Turn off the engine until the water temperature drops to normal temperature.

5. Open the front compartment flap.

6. Slowly unscrew the lid of the small kettle to release the air.

7. Add antifreeze to the max limit in the small kettle.

The steps are as follows: unplug the water plug under the water tank, drain the water, the engine is fueled, the water in the engine is discharged, the engine is extinguished, the water plug is pressed, antifreeze is added to the water tank, the engine is started, and the oil is blasted until the antifreeze in the water tank is full, and the water tank may be added if there is a shortage of water.

About 5L, do not exceed the highest scale marked in the kettle, generally prepare 6L or 7L, if the antifreeze is lost, then add it, so that you can avoid mixing with other antifreeze, you can reserve more.

The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant freezes when parking in the cold winter.

Time or **?

The time is two years or 40,000 kilometers, in fact, three years is not much of a big deal, mainly depends on whether the liquid level is almost to the end.

**In the case of the material cost of 65 and the cost of working hours 15, it will add up to about 80, and it will not be higher than 100 depending on the region

It is recommended to do maintenance together.

1 Loosen the saucer-shaped plastic screws at the bottom of the water tank and drain the water. 2 Loosen the heater hose under the driver's seat (unplug). 3 After tightening the drain screw of the water tank, add antifreeze until antifreeze flows out at the interface of the warm air water pipe, plug in the warm air water pipe, and tighten it to turn on the engine.

4 The water tank is filled and the kettle is halfway up. 5 The next morning, check the water tank and water bottle for lack of antifreeze and replenish it.

There is a waterproof port under the heat dissipation water tank, unscrew the expansion water tank cover and unscrew the water opening, and pour clean it from the expansion water tank with clean water after all the water is discharged. After the water is finished, tighten the drain, pour the coolant into the marking line up and down, and idle for about ten minutes for exhaust, and it is completed. Remember to check the level again every few days.

Changan Star is a new model with a new concept in the field of micro-cars, launched by experts from Changan Company and its international partner Suzuki Corporation for four years. The Chang'an Star not only maintains the style of the original Chang'an microcar, but also highlights it"Three highs"(High-tech, high-quality, high-grade)."Five sexes"(safety, economy, comfort, robustness, environmental protection) characteristics, Chang'an Star is praised by industry insiders as a micro-car MPV with sedan performance.

8. Replenish the antifreeze to the max upper limit to complete the operation.

Idle the first engine, and at the same time add antifreeze according to the drop of the coolant level until the liquid level is stable.

Hello: There is a small water pipe on the side of the liquid storage tank, fill it with antifreeze until the small water pipe leaks.

If you need to exhaust air, the specific operation steps of Chang'an Star second exhaust air are as follows:

1. Press the brake pedal of Chang'an Star II.

2. Twist the car key of Changan Star II and start the engine.

3. Run the engine of Chang'an Star II until the water temperature reaches 90 degrees.

4. Turn off the engine until the water temperature drops to normal temperature.

7. Add antifreeze to the max limit in the small kettle.

Most cars don't have to exhaust air.

The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function, antifreeze can prevent the coolant from freezing and bursting the radiator and freezing the engine cylinder block when parking in the cold season, but we have to correct a misunderstanding, antifreeze is not only used in winter, the normal maintenance project of the car, every year of driving, the engine antifreeze needs to be replaced, and the frequency of special vehicle antifreeze replacement is high.

There are many types of automotive antifreeze, such as calcium chloride (CaCl2) in inorganic matter, methanol (CH3OH) in organic matter, ethanol (C2H5OH, commonly known as alcohol), ethylene glycol (C2H4 (OH)2, commonly known as sweet alcohol), glycerol (C3H5 (OH)3, commonly known as glycerin), lubricating oil and common sugar, honey in our daily life, etc., can be used as the mother liquor of antifreeze. Unpolluted rainwater, snow water, etc., can become antifreeze in the general sense when the total hardness component concentration of the water quality is between 0 and 30 ppm.

If you don't need it, just add it.
