Dongfeng Nissan Blue Bird how to add antifreeze in winter

Engine coolant must be mixed with distilled water and antifreeze, and pure antifreeze cannot be added alone, as pure antifreeze will cause high water temperatures.

Antifreeze has the effect of antifreeze and the ability to prevent rust.

Antifreeze: Generally ethylene glycol or propylene glycol for our industrial use.

Its function is: to increase the "boiling point" of our engine coolant (the temperature of the cooling water boiling pot), reduce the "condensation point" of the cooling water, the service life is generally 1---2 years, there is a special test strip for measuring the concentration of coolant, the concentration of antifreeze is generally 35%--68%, and the recommended value of the general vehicle is 50%, that is: 50% antifreeze + 50% pure water constitutes engine cooling water.

The service life is generally 1---2 years.

1. First of all, the color of the antifreeze does not mean that the antifreeze is bad, the color is just the different proportions of each antifreeze manufacturer, and different pigments are added.

2. After the antifreeze is used for a period of time, it is not based on the brightness of the color to determine whether it needs to be replaced, but the concentration of the antifreeze to determine whether it needs to be replaced (the concentration needs to be tested with a special test strip, which is available in the maintenance station).

3. If you replace a different brand of antifreeze, you need to clean the previously used antifreeze to reduce chemical corrosion, and you need to clean the water tank, so it is recommended that you clean the water tank.

The scale of Bluebird antifreeze is between min and max. Below the minimum scale and above the maximum scale, the vehicle will be damaged. The full name of antifreeze should be antifreeze coolant, which means antifreeze coolant.

Antifreeze prevents the coolant from freezing the radiator and freezing the engine block or cylinder head when it is parked in the cold winter.

The role of antifreeze is mainly divided into five aspects: cooling is its most basic function, which can protect engine performance and extend service life. It also has the functions of anti-freezing, anti-boiling, anti-scaling, especially when the outdoor temperature is below zero, antifreeze can ensure that vehicle parts and components due to cold system failure.

Anti-hidden refreeze also has antiseptic function. Because the cooling system of the engine includes several metals such as steel, aluminum alloy, cast iron, copper and solder used in the welding of the water tank, the cylinder block and cylinder head are generally made of cast aluminum or cast iron, and the water tank is mainly made of copper and brass. Antifreeze must be able to protect all of these metals for a long time, and the use of deionized water and appropriate additives can prevent all kinds of corrosion.

Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round.

Nissan Bluebird Antifreeze Replacement Tutorial.

1.Let the vehicle sit for half an hour before changing the antifreeze, as the temperature of the antifreeze is relatively high when the vehicle is just turned off. Unscrew the drain screw at the bottom of the tank to drain the old antifreeze completely.

2.Keep the car idling while constantly adding clean water to the antifreeze storage tank to flush out any remaining antifreeze in the cooling system. If the water flow has no color, it can be stopped, which means that the original antifreeze is completely removed.

3.After the clean water is discharged, close the drain valve and turn off the vehicle engine. Fill the fill port with new antifreeze and the level scale should be between max and min, even if the level is slightly above the max line.

4.Light the engine again. At idling, the air in the cooling system will be expelled, which will cause the antifreeze level to drop to a certain height. Wang Gai.

5.When the liquid level no longer changes, add antifreeze between max and min, and the antifreeze replacement process ends here.

1.A medical syringe can be used, the filling port is opened, and a portion of the antifreeze is drawn with a catheter.

2.There is a drain valve under the cooling fan. Release the unit and drain excess antifreeze.

Remember not to experiment with it. The pressure inside the tank is higher than the atmospheric pressure, and the depressurization process itself is dangerous. And the drain valves are not all exposed, some are hidden, making it more difficult to operate.

Nissan Bluebird antifreeze is priced at 80 yuan per bottle. When Nissan Bluebird antifreeze is added, the liquid level should be between the max min scale marks;

This needs to be paid attention to during the use of Nissan Bluebird antifreeze.

Pay attention to storage.

Ensure that the antifreeze is stored in a cool, direct sunlight area, and at the same time, the lid should be tightened to avoid oxidation of the antifreeze in contact with the air, which will affect the antifreeze performance.

Note: Cleaning the inside of the time-changing cooling system.

When changing the antifreeze, if the inside of the engine cooling system is not cleaned, some scale and other sediments will remain inside, which will cause the antifreeze to change color significantly over time. If the color of the antifreeze changes, it is an indication that it has deteriorated. Therefore, before changing the antifreeze, make sure that the old antifreeze has been thoroughly drained and that the cooling system has been cleaned internally.

Check the antifreeze level regularly.

The liquid level of the antifreeze closed liquid reservoir in the engine compartment should be checked on time every quarter, and the normal liquid level should be between the max min scale lines.

Pay attention to change the antifreeze regularly.

In order to ensure that the engine cooling system is working properly, please change the antifreeze regularly, and the change interval is generally two years or 40,000km (depending on the brand and model).

Note that water should be added to the antifreeze.

If water is added to the antifreeze, its freezing point will rise, which will affect the cooling effect of the engine. And because of the impurities in the tap water, the antifreeze will gradually produce sediment, which will eventually affect the efficiency of the cooling system.

Bluebird's antifreeze is not oily. Antifreeze is the coolant that is added to the turbocharged intercooler, and cannot be injected into the engine water tank; The full name of antifreeze is antifreeze coolant, which is a kind of coolant containing special additives, mainly used in liquid-cooled engine cooling system, with excellent properties such as antifreeze in winter, anti-boiling in summer, waterproof scale and anti-corrosion throughout the year; Water-based and oil-based antifreeze should not be mixed, and it is not recommended to mix different brands of antifreeze, and the additives added to each antifreeze may not be the same.

Advantages of Bluebird antifreezeThe vehicle does not prevent freezing when it is started, because the antifreeze is in the cylinder, and the liquid will expand when it becomes a solid volume, so it will freeze and crack the cylinder. Another function is to liquid-cool the engine early after the vehicle is started. Anti-guess prevents the engine from being too hot, resulting in engine damage.

Antifreeze also serves to manage rust and prevent excessive limescale from causing clogged lines.

1.The new Bluebird antifreeze should be replaced every two years or 40,000 kilometers. The all-new Bluebird measures 4,683 mm, 1,780 mm in width and 1,465 mm in height, with a wheelbase of 2,700 mm, and is a four-door, five-seater sedan with a CVT transmission for a top speed of 185 km/h.

2.The front brake type of the car is ventilated disc type, the rear brake type is disc type, the parking brake type is hand brake, the body structure is load-bearing, and the steering power type is electric.

3.Antifreeze can prevent the coolant from freezing when parking in the cold winter, freezing the radiator, and freezing the cylinder to start the cylinder.
