Aggressive impact on the details of copper alloys.

Steering with a hydraulicer greatly facilitates the process of managing the car. But GUR, like every other car system, requires maintenance. For example, the hydraulic steering fluid does not always retain the constancy of the level. And in order to add liquid into the hydraulicel, you need to know which oil you can pour there.

First of all, you should find out what oil recommends pouring a manufacturer of your car. Well, in case there is no lack of such an oil, it would be nice to have an idea of \u200b\u200bwhat can be replaced. Most car enthusiasts distinguish the fluid of the hydraulic fluid in color. To evaluate how true the separation of oils on this basis, I propose to look back. In the first boxes of automata used the usual mineral motor oilThat was tinted in red so that the color of the oil puddles can immediately determine the source of leakage.

Oil composition for gur

The hydraulic fluid is an oil with certain properties that give it a different kind of additive. Despite the fact that more than 90% of its composition falls on the basis of which other oils, mineral or synthetic. His qualities are so strongly changed by additives, which without them it will not be able to ensure the normal operation of the hydraulic agent. In any hydraulic fluid, the following additives include:

• Antifriction.
• Viscosity stabilizers. They are then needed so that the oil does not make too thick at low temperatures or excessively liquid at high.
• Suppressor of foaming. Foam is formed when the oil is mixed with air. And since the air differs from the fluid in that it can be compressed, the foamed oil is much worse transfers the pressure generated by the pump on the hydraulic cylinder piston. Once the oil foams, the force generated by the GUR will decrease so much that it will be equivalent to its partial abandonment. This additive impairs the ability of the base to hold the air.
• Corrosion moderator.
• Antioxidant base.
• Paint substances.

The hydraulic fluid during the operation of this unit performs the following functions: transmission of working pressure from the pump to the piston of the hydraulic cylinder, heat removal, as well as lubrication of rubbing parts. Protection of system parts from corrosion.

Interchangeability

Oil for GUR (with the Marking of PSF OIL) of Japanese and American production can be mixed with each other if they have the same type of base. Mineral with mineral, and synthetic with synthetic, etc. Contrary to common delusion among motorists mineral oils Do not react with synthetic. But sometimes when they are mixed, there are cases of excessive foaming of the mixture. The main difference in synthetics from mineral water for GUR consists in their different impact on rubber parts. Synthetic behaves with respect to rubber more aggressively. Therefore, if the GUR is intended for use in it synthetics, then you can fill the mineral water.

Which basis of the working fluid GUR is better

Taking into account the above, you can make one conclusion - the car owner has no choice in which oil (synthetic or mineral water) pour into the GUR. This choice for it is made by a car manufacturer.

Difference oils PSF and ATF

Oils for GUR (PSF) and for automata (ATF) differ only to the presence of the last additives against slipping and wear of frictional. Therefore, with an insufficient level in the tank of the hydraulicel and the absence of a PSF fluid suitable for your car, best option Budge the oil tank for an automatic box having the same basis as recommended for your GUR.

DEXRON and its applications

The history of liquids with this name began in 68 of the last century, when the American concern General Motors mastered the release of unprecedented to this product - transmission oil for automatic boxes Changes of transmission produced by car. The company's marketers called it dexron. Somewhat later, this name has registered as a trademark of transmission fluids for automatic transmission transmissions. Under this brand GM and other liquids manufacturers for automatic transmissions Transmission oils for "automata" are produced to this day, and now not only for them. And so that you do not think that any dextro can pour into the waterwasher here is a list of liquids produced under this brand in our days:

When oil replaced in the hydraulicel

Most auto manufacturers assure their buyers that the liquid is poured into the GUR for the entire service life of the car and there is no need for its periodic replacement. Therefore, it must be changed only in two cases: after eliminating the consequences of the pump breakage or after the water from entering it, for example, when overcoming water barriers. Emulsion will tell you about entering the water system under the lid of the hydraulic tank. And in both cases you need to wash the filter located in the tank. It is better to make it better by the White spirit or a liquid similar to it.

In reality, the fluid GUR is better to change every 90 thousand km. or 5 years of operation.

In transmissions with automatic transmission (automatic transmission), a mixture is applied (Fluid), which the people are called ATF liquid. For decades, the GM General Motors concern produced quality standards in the fields of oils for automatic transmission.

Most global manufacturers aTF oils And the automatic transmission is focused on the quality of the GENERAL MOTORS Quality Specification. Since the eighties, the operating standard GM was Dextrone IID, which in after was updated on Dexron IIE. And in 1993, the Standardization of Dextro No. 3 was published on the market.

The difference between dexron IIE from Dexron IId is insignificant. However, the new generation of standards Dextrone number 3 is significantly different from predecessors. The fractional characteristics of the three-generation mixture have improved significantly, the manifestation of which has an impact on all modes of operation of automatic transmission.

All generations of dextro specifications are considered interchangeable. However, it is possible to update the transmission oil only for a new generation, the reverse action will worsen the robot of additives that are added in the DEXRON 3 mixture.

It is not necessary to replace the Dexron 2 on Dexron 3 in cases where the manufacturer of the appropriate transmission is not stated to increase efficiency in the transition to new standards.

Popular Marks Specifications

Mannol Dexron 3.

Mannol Dexron 3 Automatic is considered multipurpose oil for automatic transmissions. This mixture of MANOLOG is also used in steering hydraulic tapes, hydraulic clips, vending mechanisms.

As well as everything, without exception, oil dextro has a reddish tone. The manufacturer was thoroughly overlooked over the combination of additives and synthetic components whose components contribute to the improvement of fractional characteristics at the time of switching gear.

Oil from the manufacturer with Germany has high low-temperature characteristics, excellent antioxidant indicators, chemical stability throughout the entire period of operation. It is not advisable to use elements with copper as a lubricant, to all other alloys and materials, the liquid is absolutely neutral.

Products have admission to all possible tolerances:

The main standards of Mazda, Chrysler, Jaguar, Renault Elfmatic, RenaultMatic D2 D3, Acura / Honda, Lexus / Toyota ATF, Audi, GM Dexron 2 and 3, Ford, BMW and Mitsubishi are responsible.

Dexron 3 exploitation

Historically, it is not necessary to target mixtures from the mixtures of manufacturers. All authoritative motorists recommend paying attention to the specifications from the GM concern and standards from automatic transparents.

The main preconditions that can be focused - are the notation of "transmission" on the diploma of automatic transmission. If "Dexron III" is noted, then it is preferable to pour it. Otherwise, the consequences may be sad.

Our advice: Specify the manufacturers of your machine automatic transmission manufacturers, follow the standards from General Motors, pour the allowable transmission mixture to replace it in a timely manner. And your transmission will serve you for a long time and stable.

The automatic transmission goes the DEXRON-II oil. DEXRON-II D, it was used on the automobiles of the ancient 95g and older, it is mineral based on a more recent DEXRON-II E or DEXRON-III. In Toyota on oil probe You can read what is poured into the box. In any case, you should not mix liquid on a mineral and synthetic basis.

IN Japanese cars It is enough to know the quoca that the dexton is suitable for your machine and it can be safely pouring, but some owners of old cars face difficulties when searching for dextron2D \\ 2E. In the device on the probe, the Dextron2D can be pouring only the Dextron2D, while on automata using dextron2e you can Replace on Dextron3 (but not back, if the D3 required for the automatic transmission requires it to replace D2E). All negative opinions about such a replacement are associated with the fact that Dextron3 has a greater fluidity than its predecessor, it has a beneficial effect on the automatic transmission in the cold period, but from - the fact that in some old automatic transmission, the gaskets are not designed for such a level of viscosity of oil for automatic transmission, they give a little flow, it is not a problem in itself, unless of course give out the oil below the minimum level, in any case, it is recommended or swapped, Or periodically pour a little d3.

About the color of liquid for automatic transmission (notice, I specifically told liquids, and not butter!) Many define the fluid choice factor in color, in vain! Color, these are only dyes that are added to the factory to add manufacturers to make it easier to find sublifting, and the color difference shows on what basis ATF is made. Agel color ATF shows that the automatic transmission is filled with a liquid on a synthetic basis, and the red liquid indicates the mineral composition. Much critical compliance with the type of liquid than its color. Until recently, it was believed that it was impossible to mix liquids for automatic transmission for automatic transmission for automatic oils, because When operating temperatures, the engine oil on different bases is mixed thus folded.

It is necessary to dispel this misconception. 1-in automatic transmission does not occur such loads at which oil might be curled. The 2-input automatic transmission is used non-oil and the transmission fluid on different bases and mixing it is fundamentally no harm for the automatic transmission (and it is simply called it in the people of habit). On the other hand, it is better not to experiment with such an expensive thing in repairing a thing as an automatic transmission, especially since finding fluid on the necessary basis is not difficult in our days, so it is not necessary to move the automatic transmission to another basis, it is better to pour something to what it is accustomed to You will not get any advantages in changing oils. (Remember: you can replace the Dextron 2 on Dextron3, but not vice versa!), Buy the oil only in safe places and do not save on it, the automatic transmission is not the part of the car that is tolerate!

By the way, the same also applies to the hydraulic plates on the old cars (for those who do not know in the GR, it is also necessary to pour oil as in the automatic transmission), it is also characteristic of giving a little while using Dextron3 instead of Dextron2e.

The problem of mixing oils usually occurs when talling oil during operation. At the same time, it should be combined both basic oils and additives.

Mineral basic oils are mixed with each other without restrictions.

Semi synthetic oils - either a mixture of synthetic with mineral oil, or hydrocrack oil, are well combined with mineral oils.

Synthetic polyalphaolefin (PJSC) oils are also well mixed with mineral.

Compatibility of other synthetic oils (polyester, glycolic, silicone, etc.) with mineral oils and among themselves depends on their structure. Standards on motor and transmission oils require them full compatibility. Therefore, it can be assumed that the base oils cannot be the cause of deterioration lubricants When mixed it. Oil additives are used in the form of well-combined package sets. Adding other additives may disrupt their combination. In addition, synthetic oils have other additive sets than mineral and it increases the risk of unwanted interaction of all components of the mixture.

The result of negative interaction when mixing oils can be:

- reducing the effectiveness of individual additives, which is practically impossible to detect;

- loss of additives and their sediment oxidation products;

- increased engine pollution;

- accelerated increase in oil viscosity;

The deterioration of oil can manifest itself immediately, but after a certain time, and in general it can not be clearly discovered.

- mix only the oils of one category, for example, in aPI oil SG / CD topping only API SG / CD oil;

- mix only oils made from basic oils of one species, for example, mineral mixing with mineral.

For the same reason, oil manufacturers are not recommended to add any other improvement additives or additives into oil.

Liquid into the hydraulicel. Is it possible to mix the types of liquids.

By itself, the hydraulic amplifier device is quite reliable. With the right and regular maintenance, the hydraulicel will serve for a long time and truth.

Maintenance of the GUR system is quite simple and considerable part of motorists produces all the necessary procedures independently.

Stages of maintenance GUR.

1. Recommended replacement oil fluid in system.

In this case, the motorist has several questions: how often it is necessary to make a change of oil fluid and which composition is better to use for long-term work of the GUR?

But it seems to me that they are a little shy. If the mileage is small. I would limit myself with 1 time in 2 years. As you know, during the operation of the GUR, the oil over time comes in disrepair.

The GUR liquid plays an important role in the operation of the strengthening system, so it is necessary to carefully and selectively approach the choice of fluid. If you use high-quality lubricant for GUR, you can increase the service life of the system several times.

2. Permanent control over the level of the working mixture in the GUR system.

There is something superblock, I do not see much sense. Just periodically check the level. For example once a month. Do not know how.
Contact your service for help.

3. Timely adjustment of the GUR drive.

I would call this item a bit differently. Change the belt for yourself. Follow the stretch. It is important not to drag, it can be out of order ahead of time the pump GUR. Do not know how - again in service)

4. Reception of the fluid for the steering system.

The range of a modern automotive store consists of several types of oils for the hydraulic amplifier. The granted compositions are easily different in color. Nevertheless, the main difference between lubricants for GUR is not in color, but as part. Consider the classification of fluids in colors and compositions.

Red oil for gur.
This fluid color (as a rule is Dextron-III), refers to the class of compositions for automatic transmission and power steering. Red liquids are several species: mineral and synthetic. Therefore, before mixing two liquids of the same color, you must make sure that the oils belong to one type.

Yellow oil.
This type of fluid is one of the most common and often applied to serve modern cars. It is usually labeled PSF (which is translated by the hydraulic power steering fluid).

Green liquid for the hydraulic pot.
This mixture is used exclusively for the hydraulic power supply system and is not suitable for automatic transmission. Structure green color It can be both synthetic and mineral oil.

The most common issue is to choose between the mineral and synthetic composition. If the manufacturer's instructions are not specified specifically synthetic oil, it is best to use the mineral composition. The fact is that there are many rubber components in the hydraulic gain system. Synthetics adversely affect the operation of rubber components and accelerates their wear. In order to use the synthetic in the maintenance of the hydraulic gain system, it is necessary to make sure that the rubber components of the totality react normally to the synthetics and have a special composition.
When servicing GUR, it is necessary to take into account some rules in order not to reduce the service life of the system.

If the working mixture is replaced, use the hydraulic fluid from the proven manufacturers. The use of high-quality compositions will increase the service life of the system. Thus, you will avoid large-scale breakdowns and vehicle maintenance costs.

Classification, interchangeability, mixability.

In the people of oil for the hydraulic system, the color is distinguished by color. However, real differences are not in color, but as part of oils, their viscosity, type of base, additives. Oils of one color can be completely different and not even mixed. To say that if red oil is flooded, you can add other red oil completely incorrect. Therefore, use the table shown at the end of the page.

Three oil colors are the following:

1) Red. Family of dexron-s (mineral and synthetic oils of red mixing can not be mixed!). DEXRONES is several species, but they all belong to the class ATF, i.e. Class oils for automatic transmissions (and sometimes GUR)

2) Yellow. The family of oils for GUR yellow is most often used in Mercedes.

3) green. Green oils for GUR (Mineral and Synthetic Oils of Green Cannot Cannot!) Loves the concern VAG, as well as Peugeot, Citroen and some others. In automatic gearboxes are not suitable.

Mineral water or synthetics?

Pressure disputes about what is better - synthetics or mineral water for the GUR system are not appropriate.

The fact is that in the steering hydraulicel, like anywhere, many rubber parts. Synthetic oils are worse affect the resource of rubber parts based on natural rubber (almost all types of rubber), due to its chemical aggressiveness. In order to pour synthetic oils into the GUR system, its rubber parts must be intended for synthetic oils, and have a special composition.

Attention: rare cars Used for GUR Synthetic oils! But the synthetic oils are often used in the automatic transmission. Pour into the GUR only mineral water if the manual specifically does not specify synthetic oil!

In order not to harm the GUR system, you need to follow the rules: 1) Yellow and red mineral oils can be mixed; 2) Green oils can not be mixed with yellow or red. 3) Mineral and synthetic oils can not be mixed.

What is the difference between oils for automatic transmission from oils for GUR, and why can they be used in steering hydraulic poles?

The table below the function of the hydraulic fluids (oils) for the power steering system (PSF) and automatic transmissions (ATF):

The DEXRON-OB (Dextroy) family is initially designed for use as hydraulic oils in automatic transmissions (automatic transmission). Therefore, sometimes these oils are called transmission, which makes confusion, as under transmission oils Previously, thick oils of brands GL-5, GL-4, TAD-17, TAP-15 for gearboxes and rear bridges with hypoid transmissions were understood. Hydraulic oils are much more liquid than transmission. It is better to call them ATP-kami. ATF is decrypted as AUTOMATIC Transmission Fluid (literally - liquid for automatic transmissions - i.e. automatic transmissions)

As can be seen from the table above, oil for GUR and oil for automatic transmission differ only in the presence in the last additional additives intended for automatic transmission. But in the GUR system there is no frictional. Therefore, from the presence of these additives is not hot and not cold. This made it possible to calmly pour oils for automatic transmission to the GUR system. The Japanese, for example, has long been poured into GUR the same oils as in the automatic transmission.

In fact, if you pour suitable, high-quality, but non-original oil in the GUR, this will not affect its resource and efficiency. For example, the same ZF production pumps work on different cars with different oils, approved by manufacturers themselves, and work equally well. So yellow oils (Mercedes) and green oils (VAG) are equally good for GUR. The difference is only "in ink color."

At the same time, practice has shown that they cannot be mixed. In some cases, a foam appears in the mixture of green and yellow oils of GUR. Therefore, before using a liquid of another color you just need to rinse the system!

When mixing mineral dexron and yellow oils of GUR, no side effects occur. Their additives do not conflict with each other, but simply acquire their concentration in the new mixture and continue to perform their role.

To clarity about the mixing of different liquids for the steering hydraulic poweror, give a table below. However, the data in it relates only to the use of oils in the GUR, but not in the automatic transmission!

First group. This group indicates "Convertible" Oil. If there is a sign between them, then this is the same oil only different manufacturers - They can be mixed in any way. And the oils from the adjacent lines manufacturers do not intend to mix. Nevertheless, in practice, nothing happens is terrible if two oils from neighboring lines will be mixed. This will not worsen the operation of the hydraulic agent and will not reduce the resource.

The second group. In this group, oils are indicated that can be mixed only with each other. With any other oils from the tables above and below them, it is impossible to mix it, however, they can be used instead of other oils, provided that the system is fully flushing from the old oil.

Third group. These oils can be used in the steering hydraulic powerors only if a specific oil type is specified in the instructions on this car . You can mix these oils only with each other. With other oils, it is impossible to mix them. Also, it is impossible to pour them into the GUR system if this type of oil is not specified in the instructions. If doubt, it is necessary to abandon the use of these oils.
