Advice 1: How to change antifreeze on Nexia

Coolant (antifreeze) eventually loses its original properties and must be replaced. The technical side of this procedure is associated with the design of the car.

Daewoo Nexia: design features

The car "Daewoo Nexia" is a descendant of the German Opel, the modernized South Korean company Daewoo in 1995. Since 1996, Nexia produced at subsidiaries affiliates Daewoo in Europe and Asia. In Russia these cars come mostly from Uzbekistan. To change the coolant on a car of this model, it is necessary to know how to get to the drain tap of the radiator. This will remove the right side during front mudguard and crankcase.

About antifreeze and the frequency of their replacement

The coolant (coolant) should be changed periodically. In most manual cars you specify what to change antifreeze it is necessary once in three years or after a mileage of 45 000 km lifetime of the coolant may depend on her individual characteristics specified by the manufacturer. First and foremost, the most important indicator is the temperature of the crystallization liquid. It is clear that for the southern regions it is not necessary that this temperature was minus 40 degrees Celsius.
There is a common misconception about the fundamental difference between antifreeze and antifreeze. Meanwhile, antifreeze is one of the many brands of antifreeze. Antifreeze literally means "antisemitisme".

The procedure of draining the antifreeze on the "Daewoo Nexia"

For replacement of antifreeze you need to drive the car to the pier or put it over a viewing hole. The engine should be warmed up enough to open the thermostat valve – this will allow you to easily drain all the liquid. Just in case, to make less, poddomkratit the left side of the car body with the tilt in the front left wheel. Prepare a wide-mouthed container to collect the spent antifreeze, as well as adequate wrenches. Open the cover of the coolant expansion reservoir.
So as not to strip the threads on bolts and nuts and to facilitate the work, a pre-spray a special liquid WD-40 for rust treatment.

Unscrew the bolts securing the splash shield and remove it. The crankcase can be completely removed, and leaving the left front bolt that to push a cavity out to the side. In this case, should open access to the threaded tube with a diagonal ledge-handle. Substitute some capacity. Hand in rubber glove (better to put it on top of the cloth) remove the stopper, and the liquid will flow.

Refill with fresh antifreeze

Once all is removed, proceed to fill fresh coolant. You can pre-rinse the system with distilled water, if you go with one brand of antifreeze to another. In the case of maintaining the brand of coolant, mixing of fresh antifreeze with the remnants of anything not contraindicated.

Screw in place the drain plug. Cooling system "Daewoo Nexia" holds 6.2 liters of fluid. So pour used antifreeze into a measuring bowl to know how much it will be necessary to pour fresh. After refilling the system, start the engine and the warming-up process several times intensely "pagesuite" to better left accidentally remaining air.

Advice 2: 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 3: 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.

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 4: How to determine the antifreeze or antifreeze

Antifreeze – the General name for liquids freezing at low temperatures. Including designed for cooling automobile engines. Antifreeze brand of antifreeze that was developed during the Soviet era. Given that the brand "Antifreeze" was not patented by any copyright, many domestic manufacturers call their low-temperature cooling liquid antifreeze.
How to determine the antifreeze or antifreeze
Currently, the coolant may be referred to as antifreeze only, provided THAT 6-56-95-96. From antifreeze composition cooling liquids differ in the additive packages. This means that their quality, applicability for different motors and lifetime are not the same.
It is widely believed that the antifreeze is applicable on domestic engines, and antifreeze in the engines of cars. Following this view, many domestic manufacturers of coolants began to call their products anti-freeze. Thus, as it were hinting at the possibility of their products are used in the engines of foreign cars. Remember: only one indicator should be considered when choosing between Tosol and antifreeze is the approval of this brand coolant from the factory. To find out it can in the service book on the car or on the manufacturer's website online.
Despite the advice of many motorists to distinguish between antifreeze from the antifreeze color is impossible. And antifreeze, and antifreeze are initially colorless. Each manufacturer is free to add any dye which will fit. For example, some domestic enterprises can produce the same brand of antifreeze or antifreeze with different colors.
Often the brochures to the antifreeze or antifreeze domestic producer indicated its applicability to engines of many cars. In fact, this may well be a hoax. For example, antifreeze cars BMW Opel various in its composition and properties. No brand coolant cannot simultaneously be suitable for these engines.
The rate of spanelement antifreeze or antifreeze is not associated with the car and with the car. So for domestic toolow indicator of spanelement much lower than for the import of antifreeze. In fact this indicator is important for the manufacturer and associated with a specific type of production.
Many imported coolants do not meet domestic standards. This does not mean that they are of poor quality. The fact is that GOST is designed for traditional coolants, and according to experts is outdated and incomplete. Therefore, if the manufacturer requires the use of the car brand of the coolant does not correspond to GOST, this does not mean that it has low quality and can not be used.
Mixing different brands toolow and antifreeze is not recommended. Included in their composition additives can react with each other and cause damage to engine parts. If there is a need to change the coolant, change it all completely. Pre-flush the cooling system with distilled or boiled water. And stock up on some antifreeze of the same brand in case the topping. In extreme cases, add distilled water.
To distinguish the quality of the antifreeze or antifreeze by quality certificate from the seller, on the quality of performance of canisters and tubes, the presence of degrees of protection against counterfeiting. In addition, antifreeze or antifreeze should not have turbidity or sediment by shaking the foam should settle within three seconds. Be sure to check the requirements of GOST, TU or standards of foreign manufacturers, the coordinates of the manufacturer, production date and shelf life.

Advice 5: How to change antifreeze on antifreeze

A lot of debate is on "what is better antifreeze or antifreeze". Actually, antifreeze is antifreeze domestic production, but with its own characteristics. As part of the imported antifreezeagents and domestic antifreezeand differ, it came into use habit to separate these liquids from each other.
How to change antifreeze on antifreeze
You will need
  • - the required amount of antifreeze;
  • - capacity to drain antifreeze;
  • - water spray systems;
  • - washing liquid.
Warm the car for 5-10 minutes. Put the machine to slide forward. Put an empty container under the drain hole of the radiator. Unscrew the cap of the drain hole and gently drain the waste antifreeze. Be careful, the liquid can be very hot. Use thick gloves or mittens.
Screw the cap back on. Be careful not to exert too much effort. Otherwise it will lead to the disruption of threads and costly repairs. Fill the system with water, pre-dilute the wash fluid. Start the engine, turn the stove to maximum capacity and continue running the engine for a few minutes. Follow the temperature sensor, as prolonged use can cause overheating. Then drain the water as described in the first step.
Repeat the procedure several times. Repeat until until the drained water is clean. Drain the water and collect in a container. Remember, you cannot mix the antifreeze and antifreeze. This will lead to corrosion of the cooling system, and there will be a leak. Alternatively, rinsing can be done with running water under pressure. The flushing look good, and saving considerable time.
Put the car on a hill so that the plug hole for coolant was above the whole system. This is necessary to reduce the number Papademos the system of air and to prevent formation of air pockets. Pour in the required amount of antifreezeand run the car again. Check fluid level, if necessary top up.
Dispose of used fluid according to the rules. Either use replacement the reputable garages who have the ability to transfer the waste supplies for recycling to specialized organizations.
Antifreeze, as antifreeze, is very toxic. Keep drain and fill the fluid does not enter the skin, eyes, respiratory tract and mouth. Drain the liquid in a container, not on the ground.
