Advice 1: How to replace antifreeze in a Nissan

Technology change antifreeze - coolant – in car brand Nissan is quite simple. Through the drain holes located in the radiator and the engine is completely drained of old fluid, and in its place filled with new.
How to replace antifreeze in a Nissan
You will need
  • Phillips screwdriver, bucket, funnel, water, antifreeze.
Place the car on the overpass.
Drain the antifreeze from the radiator. To do this, Unscrew the plastic plug located on the radiator using a Phillips screwdriver.
Substitute under a radiator the bucket and let the fluid. To better flowed with the filler hole of the radiator should also remove the cover before you Unscrew the drain plug. However, be careful – the lid can spill hot antifreeze.
Pay attention to the fact that after having done the engine is still a certain amount of liquid. This residue can be drained through a hole that is in all Nissan models located on the engine itself.
Pour washing water at the top thick hose that runs from the radiator to the engine. Gradually, in small portions pass through the hose about ten litres in total. Until the engine has drained all the coolant, the water will have the color of antifreeze. Should I flush the engine, until it becomes transparent.
Pour distilled water, its volume should be about one and a half liters. Rinse the engine is already proven method. There ready pour over a liter of antifreeze and run all the way until it drains from the drain.
Free from residues of used antifreeze expansion tank. Drain the coolant via the hose that connects the tank with the neck filler hole of the radiator.
Fill the tank with water the same way once spilled out all the antifreeze. Release it out through the hose. After the process is over, return the hose in place.
Fill in new antifreeze the whole system. First pour the antifreeze into the engine. In the cars Nissan to fit about three liters.
Pour coolant in the filler opening of the radiator by loosening the drain bolt, which serves to release excess air. In the Nissan it is in the highest point of the system. Note that in models of cars of this Japanese brand, unlike others, is not necessary to remove the decorative cap from the engine to open the drainage.
In addition to distilled water, to clean the system from old antifreeze will help flush special tools.
Useful advice
When the radiator is filled with coolant completely, pour a little antifreeze in the expansion tank and start the engine, leaving the drain hole open. So run the coolant throughout the system. The whole procedure should last about twenty minutes.

Advice 2 : Where poured the antifreeze

Replacement of antifreeze, usually produced during aging of the coolant. Or is it required after repair, often replacement of the radiator. The most reliable in this case will follow the user manual for the specific car. But there are requirements for replacement of antifreeze, which for all models and brands of identical.
Where poured the antifreeze
You will need
  • - antifreeze/ANTIFREEZE;
  • - distilled water;
  • - gloves;
  • - filling funnel.
Pick up the antifreeze or ANTIFREEZE in accordance with the specification for lubricants and fluids for your car. Do not select coolants by color. Before antifreeze was really classified by color, currently it is nothing more than a marketing ploy manufacturers.
Start and operate the engine for 5-10 minutes. Slide the controller compartment heater in heating position, he should remain there during the whole procedure of replacing the coolant.
Drain all old coolant from the system. To do this, rotate the surge tank cap or a radiator to lower the pressure. Do not perform work when the engine is hot because cooling system is in a state of high pressure and when you open the valve the inevitable release of hot fluid. After fully Unscrew the cap. Open the drain valve at the bottom of the radiator and drain the antifreeze.
Fill the system with distilled water or washing liquid, having closed the drain valves. Don't forget that you can not pour cold water into a hot motor. Tighten the tube. Run the engine for 5-10 minutes to pump the cooling system. Repeat the procedure draining fluid. The need for repeated flushing identify as drainage water: it must be clean. Can pre-rinse with tap water by inserting a hose to the input to the system and feeding water under pressure. And then finally clean with distilled water or wash fluid with the engine running.
Pour the new antifreeze into the neck of the radiator and expansion tank. In the case of nonseparable radiator liquid is filled only into the tank. Don't confuse surge tank with obywatelem! Follow the fluid level. In the radiator it needs to be lower cut neckline in the tank - between the marks of minimum and maximum, but at the first gas station you can fill to the maximum, because the liquid will fill the cavity system, the level in the reservoir will fall.
Bleed the air through the screw/tap on the engine block until the appearance of liquid droplets. Tighten the faucet until it stops. Again, run the engine, check the antifreeze level, if necessary top up.
Replace the antifreeze every 2-3 years because it gets old and loses its properties. Do not mix different brands of coolants, it is unknown what kind of reaction they will give when interacting. Can form harmful to the working substance and precipitation that can bring down the pump, clog the cooling system. The result is an overheated engine in need of overhaul.
Useful advice
Antifreeze is realized mainly in two types: concentrate and diluted. If you purchased a concentrate, you dilute it in the ratio 1:1 - quart of antifreeze per liter of distilled water. But pay attention to the manufacturer's recommendations concerning the desired proportions for dilution of concentrate.

Advice 3 : Can I mix antifreeze with antifreeze?

Antifreeze and antifreeze - means for cooling automobile engines. Some motorists do not see them as a fundamental difference, others doubt the quality of the good old antifreeze, and the third one safely mix these liquids.

Protivozmeinaya fluid (antifreeze)

If the coolant in the jacket of the engine flooded with water, in case of leaving her in the cold, resulting ice expands and will damage the internal parts, if not break the body of the shirt. Special coolants for vehicles to prevent damage to your items, because they have a lower freezing point and, moreover, during crystallization of the antifreeze turns into a mushy mass, which is not able to bring harm to the parts. Crystallizes, antifreeze lose fluidity, and therefore is no longer able to fulfill its mission.

Antifreeze, used as coolants for vehicles, created on the basis of ethylene glycol, diluted with water, with the addition of various additives. The latter are intended to give the solution additional properties: anti-corrosion, anti-cavitation agent, anti-foaming and fluorescence (staining).

Antifreeze – antifreeze is also

It so happened that we all were forced to participate involuntarily in this paradox of the Russian language. Probably, many not often heard such a dialogue:
- You have antifreeze poured?
- No, I have not antifreeze. I have antifreeze.
ANTIFREEZE acronym stands for: technology of organic synthesis of OL (i.e., alcohol).

The common name "antifreeze" became its own, although within this the names of a number of different grades, denoted by Latin letters and numbers. This was originally the proper name noun "antifreeze" became a household word. Meanwhile, the word "antifreeze" is a General name for all non-freezing liquids. It translates as "non-freezing, anti-freeze".

Can you mix different brands of antifreeze

"Can you mix antifreeze with antifreeze?" – this is often how the question motorists, without going into the variety of both. As mentioned, different brands of antifreeze contain different additive package, sometimes conflicting with each other. The result is that it can precipitate and clog the system.
If you still had the trip to mix different coolant on arrival at the garage thoroughly rinse the cooling system with distilled water. The same must be done when moving from one antifreeze to another.

Based on the foregoing, it is better not to mix fluids, especially if they have different distinctive colors. First of all, it just refers to domestic green antifreeze and foreign antifreeze, which often red.

Advice 4 : How to replace antifreeze

Regular replacement of antifreeze needed to maintain the normal operation of the machine. It is important to know what to replace the coolant every 45 thousand kilometers of the car. Then your engine will continue its work in standard mode, will not corrode and overheat. Also, this procedure is recommended 1 time per year. The fact that special additives in the liquid, preventing the destructive processes, over time, lose its protective properties. And when that happens, the radiator and the engine begin to break down under the action of electrolytic corrosion.

The definition of quality antifreeze

Testing antifreeze is made using special strips. Usually they are sold together with the liquid and have a special scale. If dipping the test strip into the liquid, it will change color and then you can determine the condition of the antifreeze and identify the need for its replacement.

Special attention should be paid to engines, consisting of aluminum parts. In order to protect the engine, should prevent signs of rust (even basic) on the aluminium parts.

Replace the antifreeze with your hands

Performing works by independent replacement of antrepriza, you need to remember that it is toxic. Therefore, the place for such work should be kept away from children and Pets. In addition, it is important to strictly observe necessary safety regulations, which are not allowed to discharge the waste coolant into rivers, lakes and streams and close to water sources - columns, wells, etc.

Antifreeze is allowed to change only on a cold engine. To perform work on a hot engine is very dangerous. So, remove the radiator cap and then open the drain cover, pre-setting under it a capacious bucket. Then drain the antifreeze. Inspect the system hoses for breaks and cracks. If necessary, replace the hoses.

Before filling with new antifreeze, flush the cooling system to eliminate grease, rust and various deposits. There are special tools for flushing a coolant system. Pour the entire bottle of this means to the radiator and then fill it in the tank and demineralized or deionized water to the brim. Close the lids.

Turn to maximum the engine and the stove. Wait until the engine reaches operating temperature and then turn it off and let it cool. Remove the caps from the radiator and drain the fluid.

Pour in the cooling system normal water, close the lid and turn the engine for 15 minutes. Then again let it cool down completely. Drain the water from the system and then refill with new antifreeze.

Pour it in accordance with the recommendations of the manufacturer. Allowable concentration of antifreeze in the cooling system should be no more than 70%, and the optimum is 50% water and 50% antifreeze. After it fills turn at maximum torque, and heating in the car. It is necessary to distribute the antifreeze throughout the system and removing the air bubbles.

After a few days of driving the car check the available level of antifreeze in the cooling system. If necessary, fill to the desired mark.

Advice 5 : How to change antifreeze on "Chevrolet Lacetti"

The better the coolant in the system, the less chance of overheating the motor. Engine overheating and terrible fact that there is an intensive wear of all moving parts. Also there is a spontaneous ignition of the fuel mixture in the combustion chamber, the detonation occurs.
How to change antifreeze on "Chevrolet Lacetti"
Antifreeze is necessary not only for engine cooling and to lubricate the coolant pump. Lubrication is due to the substances contained in the coolant. In addition, the coolant water contains many chemicals which counteract the formation of scale and deposits. But these chemicals have a relatively short period of existence.

So, the manufacturer strongly recommends to replace fluid every 45 thousand kilometers of mileage. In fact, you have to control the acid-alkaline balance in the system. The high content of acids or alkalis can lead to the destruction of the system nodes and to the continued erosion of the walls of the cooling jacket in the engine block. To check the balance by using special indicators.

Preparation for the replacement of antifreeze

The first thing you need to give the engine to cool. Will have to completely drain the old antifreeze from the system, as hot liquid can be very Ambaritsa. And don't forget that the toxicity of antifreeze is very high, therefore it is best to protect hands when working with him. Wear rubber gloves and a respirator.

Now you need to drain the old antifreeze into a container. To do this, remove the motor protection, to provide access to the drain taps on the bottom. Under drain substitute capacity, then only open stub. Don't forget about the stove, it faucet need to open completely to leaked out all the antifreeze.

After draining, close all tube and flush the system with special solutions. To do this, pour into the tank washing liquid, and then start the engine. You need to bring the temperature of the working engine. Do not forget to turn the stove on full power to the system is not a single air bubble.

Replacement of antifreeze

After reaching operating temperature, stop the engine and allow it to cool him. Only after that drain wash fluid. Fill with new antifreeze mixed with water in a ratio of 50/50. Antifreeze can be increased to 70%, but more is not recommended. Close all inlets again start the engine and turn the heater up to full power.

Operate the motor for as long as the antifreeze will not heat up to operating temperature. Be sure to turn on the stove so that the fluid circulated all over the system. It is also recommended to remove the thin hose going to the throttle. Wait until it will be fluid and install in place.

Advice 6 : When you need to change the antifreeze

Maintain the vehicle in optimum condition is a primary responsibility of the driver. After all, how the machine is ready for operation, security depends equally as its owner and other road users. Time replaced the antifreeze will help to avoid serious problems with the engine overheating or corrosion inside the fuel system. This means that the quality of the coolant has to be the most serious.
When you need to change the antifreeze

It is known that for efficient operation of the antifreeze effect of the so-called additive or additives. Usually it's the borates, silicates, phosphates are sometimes elements that are responsible for protection against electrolytic corrosion. By reducing the amount of these elements, resistance to corrosive processes during the working cycles of the engine is sharply reduced. Clear what to change antifreeze it is necessary before he will cease to perform its function. The question arises: how do you determine that the coolant is stopped "working", but still make it in time?

Manufacturers of antifreeze has developed a very effective and easy way to check the working condition of the fluid using the test strips and the special scale of quality. The driver enough to moisten the test strip with antifreeze and that certain way will change its color. You will then compare this color with the scale and thus determine, that whether the time of replacement of the liquid or it can be a time to ride the old antifreeze.

Manufacturers of coolants is recommended to change the antifreeze after the level of 45000 km. Some suggest that to guarantee the anti-corrosion effect, you need to change the coolant at least once per year regardless of the number of well-worn miles. New developments, presented by well-known manufacturers of antifreeze in the global automotive market, the promise of 100,000 km without replacing the fluid. However, it should be borne in mind that the consumption, effectiveness and duration of the antifreeze depends on the brand of machine and operating conditions of the vehicle.

Despite the current myth that pure antifreeze is much better, more effective and at the same time more economical than the mixture, manufacturers in their instructions quite clearly write, in fact need to use coolant. At an optimal concentration of the mixture should be equal, that is 50% water 50% antifreeze. Experts note that the increased proportion of antifreeze to 70% under certain conditions is acceptable, but pure antifreeze rather "ruin" the engine than it helps him.

Advice 7 : How to check the antifreeze level

Antifreeze is a liquid which is designed to cool the engine, otherwise damage may occur parts. It is important to check the level of antifreeze and carry out its replacement.
How to check the antifreeze level
Look in the surge tank, which check the level of antifreeze. It should be between the minimum and maximum clipping. If the fluid is below the required level, then perform the refilling of antifreeze to the desired mark.
Remember that antifreeze needs to be of high quality, which is suitable for aluminum engines. Be careful to use the same brand of fluid, because constant change can lead to corrosion and to defects in the cooling system.
If you see that the tank is completely empty, and there's not a drop of antifreeze, then check it the level in the radiator. To do this, Unscrew the radiator cap. Remember that let out pressure from the system by unscrewing the cover counterclockwise. Be careful to not remove the cap when hot antifreeze, because in this case the jet can seriously burn you.
After checking the coolant can replace coolant if not satisfied with its quality. To do this, make sure that the radiator and engine are cooled down condition. Remove the drain plug and drain the coolant.
Then push the hose onto the special bolt which is in the back of the engine compartment. Pour the same antifreeze in the radiator, do it before the start of the neck. Close the cap and start the engine, wait until it warms up, and stop. Add coolant to the reservoir was completely filled.
Turn on the air conditioning or climate control for the greatest cooling. After that, stop the engine and check the level of antifreeze in the radiator. If necessary, perform refilling of liquid. Do the same with the climate control to maximum temperature. Make sure that the level of liquid were at a constant level.
