What to fill in gur lancer 9. Different types of oils

normal operation power steering is possible only with the timely replacement of the working fluid and following the recommendations for choosing oil for Lancer 9.

Power steering directly affects the safety of the car and driving comfort. Malfunctions in the hydraulic boosters lead to the fact that it becomes harder to turn.

Prolonged operation of the Mitsubishi Lancer 9 with an old or incorrectly selected fluid leads to failure of the steering components and can cause the pump to jam.

Power steering oil

Overview of oils in power steering Mitsubishi Lancer 9

From the factory, the original Dia Queen PSF oil with article number 4039645 is poured into the power steering circuit. The cost for branded power steering fluid is about 400-600 rubles. By purchasing Dia Queen PSF, the car owner receives a number of advantages:

• good anti-corrosion properties;
• low influence on the elements of the power steering circuit;
• long-term operation with preservation of original properties;
• low kinematic viscosity;
• small thermal expansion;
• no foaming.

original power steering fluid Mitsubishi Lancer 9

Mobil 1 ATF 320 is a complete analogue of Dia Queen PSF branded oil. It has the same performance properties as the original. At the same time, Mobile has a lower price and is easier to find on sale. For these reasons, Mobil 1 ATF 320 is most commonly used in the Lancer 9.

In the absence of Mobile in the Power Steering Lancer 9 official dealers accept third-party oil fills that comply with Dexron 3, such as Castrol Dexron III. More detailed information about the analogues of the original power steering fluid Lancer 9 is presented in the table below.

Frequency of control and replacement of the working fluid of the power steering

According to official recommendations, it is necessary to check the level of the working fluid in the power steering reservoir Lancer 9 every 15 thousand km. In this case, there should not be a significant decrease in the amount of oil, which indicates a depressurization of the power steering circuit.

Replacement of the working fluid is required every 105 thousand km. In this case, it is necessary to focus on the operating conditions of the machine. In some cases, the interval for filling fresh fluid has to be reduced to 40 thousand km. In addition, an unscheduled change of power steering fluid is required when the following reasons are identified:

• Availability extraneous sounds when turning the steering wheel;
• a burnt smell coming from the power steering reservoir;
• jamming when turning;
• black or rusty liquid;
• the appearance of deposits on the tank;
• oil heterogeneity;
• lack of accurate data on the time of the last fluid change.

Required Tools

In order to change the power steering oil, you need the tools that are shown in the table below.

Table - Required tools for replacing power steering fluid

Mitsubishi Lancer 9 power steering oil change process

In order for the replacement of the Mitsubishi Lancer 9 power steering fluid to be successful, it is recommended to use the instructions below.

• Open the cover of the expansion tank.

Power Steering Expansion Tank

• Put a hose on the syringe.

• Install the bottle next to the expansion tank. Using a syringe with a tube, pump out the old liquid as much as possible.

• Pull out the top return hose.

• Plug the fitting with a pencil.
• Put the return hose into a plastic bottle. The tube can be pushed into the top of the neck. Some car owners make a special cutout on the side of the bottle in order to reduce the risk of overturning the container or spilling liquid.

Inserted return hose into the bottle

• Pour new oil into expansion tank. At the same time, it is desirable that its level be equal to or higher than the “MAX” mark.
• Displacing the old slurry is possible in two ways. The first time you need to start the engine for a few seconds. In the second, you need to turn the steering wheel from lock to lock. Regardless of the method chosen, it is extremely important to ensure that the liquid does not go all out of the tank. To do this, periodically pour it.

• When fresh oil flows from the return line, it is necessary to return the hose to its place.
• Add fluid up to the maximum mark.

Oil level "MAX"

The power steering fluid in the Mitsubishi Lancer 9 should be replaced at least once every 2-3 years or every 100,000 runs. At self service car, we advise you to replace it more often - once every 60-80 thousand km. Over time, the power steering fluid loses its properties, hence it can be replaced that the steering wheel becomes tighter than before.

How to determine if a replacement is needed

The steering wheel turns with effort - this indicates that most likely the fluid has exhausted its resource and needs to be replaced.

A characteristic hum and sound when the steering wheel is turned to the sides may also indicate a replacement.

If you do not understand the quality of the liquid and cannot determine the need for a replacement, then you should contact a car service specialist.

What power steering fluid to choose to replace with Lancer 9

From the factory, Mitsubishi Lancer 9 was filled with the original liquid article 4039645. The cost of 1 liter in an iron can at the time of writing was about 850 rubles. In addition to it, you can choose other liquid analogues, cheaper, but also of good quality.

• Mobil ATF 320 article 152646 price for 1 liter about 500-550 rubles
• Castrol Dexron III article 157AB3 price for 1 liter about 500-530 rubles

To replace, 1 liter of oil is required.

Instructions for self-replacement

So, to replace, we need a syringe with which we will pump out the old oil from the expansion barrel.

A hose about 20 cm long, which we will put on a syringe.

An empty 1.5 liter bottle, as well as a screwdriver and pliers.

First of all, we pump out the old liquid from the expansion tank (located on the right in the direction of travel). There is a mesh at the bottom of the barrel, so the gur oil is not completely pumped out.

Now, to drain the remaining liquid, remove the clamp of the lower pipe, disconnect it and drain the liquid. We put the pipe and clamp in place.

We remove the upper pipe and muffle it and the hole in the tank. And put the return hose in a plastic bottle, as oil residues will come out of it.

We monitor the state of the liquid level in the tank. The old liquid through the return line will enter our plastic bottle, and the new one will enter the system. As soon as the return hose goes pure liquid replacement is completed.

There is a second way faster, but it has disadvantages. It is not necessary to turn the steering wheel, you can turn the engine several times with a starter, thereby the old liquid will go into the bottle, and the new one will fill the system in the same way. However, if oil leaves the reservoir and air gets in, the gur pump may burn out.

After a new clean liquid has come out of the return hose, put the hose in place. We start the car, turn the steering wheel several times in different directions and look at the level in the tank. If necessary, top up to a normal level between Min and Max and tighten the reservoir cap.

This completes the replacement of Gur fluid with Mitsubishi Lancer 9. Now the steering wheel should turn much easier.

The fluids used in the hydraulic booster can be divided according to several criteria:

• Color;
• Composition;
• Variety.

Color classification

It is wrong to be guided only by color gradation when choosing oil, although this practice is widespread among car owners. It is also often indicated which color of the liquid can be mixed and which should not.

Mixing is contraindicated in liquids by composition and not by color, and since now both mineral water and synthetics can be represented in any color, this information should be treated very carefully.

Red transmission ATF oil, usually synthetic, the Dexron brand from General Motors is considered the reference brand, but there are products from other manufacturers, such as Revenol, Motul, Shell, Zic, etc.


The yellow oil produced by Daimler and under its license is used in Mercedes-Benz hydraulic boosters. It is synthetic and mineral.

Green oil. For the most part, multifunctional and universal fluids, the composition can be both synthetic and mineral. Used in hydraulic boosters, suspension and other systems that operate on liquids. Do not mix with other colors, unless the manufacturer claims full compatibility, for example Comma PSF MVCHF is compatible with some types of Dexron.

Liquid composition

According to the composition of the power steering fluid, it can be divided into mineral, semi-synthetic and synthetic. The chemical composition determines the basic set of functions of the oil:

• Viscosity characteristics;
• Lubricating properties;
• Protection of details from corrosion;
• Anti-foaming;
• Thermal and hydraulic properties.

Synthetics and mineral water cannot be mixed with each other, since the types of additives in them have fundamental differences.

Synthetics

These are high-tech fluids, the production of which uses the most modern developments and additives. Oil fractions for synthetics are purified by hydrocracking. Polyesters, polyhydric alcohols and additive packages give them outstanding characteristics: wide operating temperature range, stable oil film, long service life.


The main reason why you can not fill hydraulic fluid on a synthetic basis in power steering, intended for mineral ones - its aggressive effect on rubber products, of which there are many in the hydraulic booster. Where synthetics are used, rubber has a completely different composition and is made on a silicone basis.

Semi-synthetics

A mixture of synthetic and mineral oils, thanks to which the latter receive significant improvements in performance: reduced foaming, fluidity, heat dissipation.


Semi-synthetic fluids include such well-known fluids as: Zic ATF Dex 3, Comma PSF MVCHF, Motul Dexron III and others.

mineral water

Mineral-based oils contain petroleum fractions (85-98%), the rest is additives that improve the performance of the hydraulic fluid.

They are used in hydraulic boosters containing seals and parts based on ordinary rubber, since the mineral component is neutral and not harmful to rubber products, unlike synthetics.


Mineral fluids for power steering are the most inexpensive, but they also have a short service life. Mobil ATF 320 Premium is considered a good mineral water, Dexron oils up to and including the IID marking were also mineral.

Various types of oils

Dexron- a separate class of ATF fluids from General Motors, produced since 1968. Dexron is a trademark, manufactured both by GM itself and by other companies under license.

ATF(Automatic Transmission Fluid) - oils for automatic transmissions, often used by Japanese automakers and power steering.

PSF(Power Steering Fluid) - literally translated as power steering fluid.

Multi HF- special, universal fluids for power steering, having approvals from most automotive manufacturers. For example, the CHF liquid produced by a German company Pentosin (pentosin), received approvals from BMW, Ford, Chrysler, GM, Porsche, Saab and Volvo, Dodge, Chrysler.

Can oils be mixed?

Mixing is acceptable, but the manufacturer's recommendations must be followed. Most often, the packaging indicates with which brands and classes of oils this or that power steering fluid can be mixed.

Do not mix synthetics and mineral water, as well as different colors, unless specifically directed to do so. If there is nowhere to go, and you have to pour what is at hand, replace this mixture with the recommended one as soon as possible.

Is it possible to fill engine oil in the power steering

Motor - definitely not, transmission - with reservations. Let's take a closer look at why.

To understand whether other oils, such as engine or transmission oils, can be poured into the power steering, you need to know what functions it performs.


The fluid in the power steering must cope with the following tasks:

• Lubrication of all hydraulic booster units;
• Protection against corrosion and wear of parts;
• Transfer of pressures;
• Anti-foaming;
• System cooling.

The above characteristics are achieved by adding various additives, the presence and combination of which endows the power steering oil with the necessary qualities.

As you understand, tasks engine oil somewhat different, so it is highly not recommended to fill it in the power steering.

Relatively transmission oil everything is not so simple, the Japanese often use the same ATF fluid for automatic transmission and hydraulic booster. Europeans insist on using special PSF (Power Steering Fluid) oils.

What liquid to pour into the power steering

Based on this, the answer to the question “what kind of oil to pour into the power steering” is obvious - recommended by the manufacturer of your car. Often the information is indicated on the expansion tank or cap. If there is no technical documentation, call the authorized center and check.

In any case, experiments with steering are unacceptable. Not only your safety, but also those around you depends on the serviceability of the power steering.

How much oil in power steering

Typically for replacement passenger car 1 liter of liquid is enough. For trucks, this value can reach 4 liters. The volume may slightly change up or down, but it is worth focusing on these figures.

How to check the level

To control the fluid level in the power steering, an expansion tank is provided. It is usually labeled with a MIN and MAX value. Depending on the brand of the car, the inscriptions may change, but the essence does not change - the oil level should be between these values.

How to top up

The topping up process itself is simple - you need to unscrew the cap of the power steering expansion tank and add so much liquid that it is between the MIN and MAX marks.

The main problem when adding oil to the power steering is its choice. It is good if the replacement has not yet been made, and the system contains liquid from the manufacturer's factory. In this case, it suffices to refer to technical documentation, take the recommended oil and add to the required amount.

If you don’t know what is poured into the system, we recommend that you immediately replace it, because in any case you will have to buy a canister of liquid for topping up.

It is recommended to change the oil in the power steering at least once every 100,000 km. or 3 years, whichever comes first. Although, judging by its condition, it can be changed more often, especially since it is not at all expensive, around 200 rubles per liter. Oil change is carried out by the substitution method, i.e. no need to completely drain the old oil before filling with new. Everything will happen in sync.

The following fluids are suitable:

• Mobil 1 ATF 220
• Castrol Dexron III

They resemble cherry juice in color, especially if you buy oil for bottling from a barrel into a one and a half liter plastic bottle. 1 liter of oil is required for replacement. If you take on tap, you can also purchase 1.5 to thoroughly rinse everything.

The photo Castrol oils Dexron III:

Let's change the oil

1. First of all, open the lid of the power steering expansion tank, then with the help of such a syringe we pump out the oil, it will not go away until the end, since there is a mesh inside the tank.

2. We take out the upper return hose and plug the fitting with some device:

3. Then we put the just pulled out return hose into a plastic bottle:

4. Pour new oil into the expansion tank up to the MAX mark.

5. Then we start the engine for literally 2-3 seconds, the old liquid will begin to pour into a plastic bottle, and the new one will decrease from the tank. It is necessary to do this procedure with an assistant so that he monitors the liquid level. It must not be allowed to completely leave the tank, otherwise the pump will take a sip of air, and this is not known how it can affect its operation.

6. Repeat the previous 2 points until clear liquid begins to pour into the plastic bottle.

7. We dress the oil return hose in place

8. Top up the liquid level to the MAX level.

10. We start the car, for fidelity, you can turn the steering wheel. If the liquid has subsided, top up.

This completes the hydraulic oil change procedure.

It is advisable to change the oil in the power steering at least once every 100,000 km or every three years - it all depends on what happens first. Nevertheless, if we take into account its condition, the replacement may be more frequent, and the cost of it is insignificant - within 200 rubles per liter. The oil is changed using the replacement method, which means that it is not necessary to completely drain the old oil before filling in the new one. In addition, it is a synchronous procedure.

Suitable for the following fluids:

• Dia Queen PSF (original, no. 4039645 )
• Castrol Dexron III
• Mobil 1 ATF 220

They are similar in color to cherry juice, in particular, if you buy draft oil from a barrel into a plastic bottle with a volume of one and a half liters. To replace, you will need 1 liter of oil. You can buy 1.5 bottled oil to rinse everything properly.

You will also need:

• large syringe (10 cc)
• a piece of hose (to put on a syringe) 10-20 cm long
• any plug of suitable diameter or a pencil so that you can close the hole in the power steering reservoir
• 1.5 liter plastic bottle
• pliers or pliers
• slotted screwdriver
• scissors
• assistant

Symptoms of power steering malfunctions

You can determine the main signs of a malfunction of the power steering on the 9th generation Lancer yourself according to criteria such as:

• oil leakage in the area of ​​​​the pump, the expansion tank of the power steering and the attachment points of the hydraulic booster,
• > increased oil consumption, can be seen by the liquid level in the expansion tank,
• deterioration of the hydraulic booster (the steering wheel is harder to turn),
• whining sound when turning the steering wheel.

Step-by-step guide to changing the oil in the power steering (GUR) on Lancer 9

The process of changing the oil consists in the following sequence of actions:

1. First you need to open the cap in the expansion tank of the power steering, then use a certain syringe to start pumping out the oil. It will not go to the end, because there is a mesh inside the tank.
   
   
   
   
   
   
   
2. Pull out the upper return hose and plug the fitting with some tool.
   
   
3. Next, put the return hose just pulled out into a plastic bottle.
   
   
4. New oil must be poured into the expansion tank up to the MAX level.
5. Then start the engine for only 2-3 seconds, as a result of which the old liquid will begin to pour into a plastic bottle, and the new one will decrease in the tank. This procedure should be performed together with an assistant so that he can monitor the fluid level. In no case is it unacceptable for it to leave the tank completely, otherwise, the pump will capture air, and this may not know how to affect its operation.
6. Repeat the previous two points as many times as necessary for clear liquid to start pouring into the plastic bottle.
7. Put the hose back in place to reverse the oil.
   
   
8. Add liquid to the maximum level.
9. Start the car and for reliability, you can turn the steering wheel. It is necessary to add liquid if it has subsided.

At this stage, the procedure for changing the oil in the hydraulic booster is completed.
