16.07.2021 Cooling system

In this article, we will talk about how the oil is changed in the box, razdatka and bridges of the Chevrolet Niva. Application of quality lubricants for vehicles plays an important role in the operation of any car. The most common for the transport to work properly is oil change process... It is possible to change the oil on your own, without the help of auto service employees, while significantly saving money.

The Chevrolet Niva is a full drive vehicle. Correctly selected oil for the transfer case, as well as all the bridges of an SUV, is a guarantee of long-term operation of all auto transmission mechanisms. The oil helps to reduce friction, which means that the wear period of the parts is significantly increased. The table below shows the characteristics of refueling fluids for Chevrolet Niva, taken from official instructions on the operation of the machine.

What kind of oil to pour into the Chevrolet Niva transmission?

The choice of oil for the transmission of Chevrolet Niva cars is carried out on the principle of inadmissibility of mixing oils, the compositions of which are different. As for the viscosity characteristics of oils, it is better to give preference to the use of the following oils:

  • 75w-90;
  • 80w-85;
  • 80w-90.

Oils intended for dispensing in an off-road vehicle are designated by the API GL-4 index. A small amount of oil is required for replacement: about 0.8 liters.
During the first filling of oil into the Niva distributor, you should remember how much of it is used. This will allow subsequent oil changes to be carried out without difficulty.

From the experience of auto repairmen and car enthusiasts good oil for Chevrolet Niva transmissions are produced by the following manufacturers:

  • Gazpromneft: G-Box GL-4 / GL-5 75W-90, G-Box GL-5 75W-90;
  • Lukoil: TM-4 75w-90, TM-5 75w-90;
  • Shell: Spirax S4 G 75W-90 (Getriebeoil EP), Spirax S5 ATE 75W-90 (Transaxle Oil), Spirax S6 AXME (Spirax ASX);
  • Castrol: Syntrax Universal Plus 75W-90, Syntrans Transaxle 75W-90, Syntrans Multivehicle 75W-90;
  • TNK: Trans KP Super 75W-90, Trans Gipoid Super 75W-90;
  • ExxonMobil: Mobilube 1 SHC 75W-90

Changing the oil in the Chevrolet Niva gearbox

To change the oil in the Chevrolet Niva gearbox, you will need the following tools:

  1. steel hex key 12;
  2. wrench 17;
  3. container for draining the used lubricant.

Sequence of actions for gearbox oil change The fields are as follows:

  1. Place the car above the inspection pit or drive it onto an overpass for the convenience of work. Before draining the old gear oil, be sure to warm up the engine... This is necessary in order to drain the oil out of the box as much as possible and without residue.
  2. Go down into the inspection hole and place the container under the drain hole, taking into account the bend of the outgoing jet. It is convenient to use a funnel.
  3. Clean the locations of the filler and drain plugs at the checkpoint, as shown in the photo above.
  4. First, it is better to unscrew the filler plug, and then the drain plug with a hexagon.
  5. Now you need to wait for all the waste oil to drain to the last drop.
  6. There is a special magnet on the drain plug, to which all metal shavings are attracted. If there are steel particles on the plug, they must be removed. And another important point from the point of view of diagnostics - the more of these particles present on the cover, the less the transmission will last.
  7. When the old used oil glass, you need to screw it drain plug and start flushing the crankcase. To do this, fill in about 1 liter of special flushing fluid and let the car run for 2-3 minutes. In this case, you need to turn on the neutral in the transfer case and shift the gears with the clutch.
  8. Further, the flushing liquid is drained in the same way and instead of it new oil is poured in the required volume.
  9. After filling the oil, check the oil level on a level surface and. Within 2-5 minutes it is necessary let the motor run in the first gear position. After that, the oil level is checked and if it falls, then you need to top up a little more.

Carrying out an oil change in a Chevrolet Niva distributor

As for this car model, it is necessary to change the oil every 50-80 thousand kilometers... As soon as the car passes more than 120 thousand kilometers of track, the oil should be changed every 45 thousand kilometers.
For information! The vehicle operating instructions contain information on the frequency of oil changes, which each car owner must follow. But it will be more correct if the oil change procedure is carried out a little more often. This is due to the fact that car oil accumulates dust and dirt in itself, which eventually leads to contamination of transport mechanisms. That is why many car owners advise changing oils more often than indicated in the instructions.
So that the oil can be drained without problems, you should start changing it after a trip. On the way, the oil has time to heat up, thereby taking on a more liquid consistency.
Changing the oil in the dispenser is not as difficult as it seems at first glance. To replace it, you need to drive the transport to the inspection pit, or lift the car on a lift. You will need a container designed to drain the oil, as well as a rag, which must be used to remove all smudges. Do not forget about the hex key (size 12), and you also need to have filling syringe .

Draining and pouring oil into the Chevrolet Niva distributor

1. The first step is to unscrew the drain plug. Then the oil is poured into a prepared container.
2. The old oil is checked for metal shavings. It is also worth paying attention to the built-in magnet - inspect it.
3. Impurities and impurities i on the cork should be cleaned. After that, the plug should be screwed back on.
4. The filler hole has a screw plug and must be unscrewed.
5. The gear oil is filled through the filling syringe.
6. Is subject to inspection and cleaning vent valve.
7. It is necessary to remember or note in a notebook the mileage that was on the car at the time of the oil change.

More oil change in the Niva razdatka is shown in a good video below.

The choice of oil for the front and rear axle Chevrolet Niva

In order for the axles of the Chevrolet Niva brand all-wheel drive car to work smoothly and for a long time, attention should be paid to purchasing high-quality oil. The front gearbox has an oil filling volume, equal to 1.15 liters, and the rear 1.3 liters... It takes about three liters to change the oil.

Changing the oil in the axles of the Chevrolet Niva SUV

For this procedure, it is recommended to observe the maintenance of the transport, as well as the rules for repairing an SUV. The oil change in the bridges of the car should occur every 40 thousand kilometers (applies to cases of operation of the Niva under normal conditions). If the car is operated in more difficult conditions, then the oil change should be done much earlier.

Preparation for changing the oil in the Chevrolet Niva axles

Changing the oil in the axles of the vehicle is identical to the procedure for changing the fluid in the transfer case. You should drive the SUV onto the inspection pit or onto a lift. The volume of oil required is the same as for the transmission. Warm up the Niva before changing the oil. Next, you need a 12 key - a hexagon, a 17 socket with a wrench, a container for draining the used oil, a rag. You should also take care of the availability filling syringe.

The all-wheel drive monster of the Chevrolet Niva works flawlessly, you just need to follow the instructions, carry out maintenance of the handouts on time, monitor the volume of oil in it, and also change all technological fluids.

The pride of the domestic auto industry is the Chevrolet Niva. The manufacturer has released a truly luxurious car, which is not inferior in its characteristics to its expensive counterparts. Off-road, nature trips, fishing, hunting - better cars can not found.

How do I change the oil?

How to independently replace process fluids in Chevrolet Niva? To do this, you need to purchase high-quality oil, which is recommended by the manufacturer. All required volumes are indicated in the instructions for the car. For beginners, the replacement process may seem daunting, but in reality it is not.

The choice of oil for four-wheel drive car a very important point, the service life, wear of parts and the operation of all distribution mechanisms depend on this. You need to buy liquids that the manufacturer recommends or proven, well-known brands. There are different types of oil for different seasons, they differ in viscosity and are adapted to work at a certain temperature.

If the car was purchased used, it is better to immediately check the level of all fluids and replace them.

What kind of oil to use in the transmission?

Different types of oils cannot be mixed. In terms of viscosity, it is better to choose a liquid with the following markings: 75W - 90; 80W - 85; 80W - 90. Manufacturers who have proven themselves well and produce brands that are suitable for an SUV are: Gazproneft, Lukoil, Shell, Castrol, TNK, Exxon Mobil. Transmission oil must be of high quality, the correct operation of all mechanisms in the Chevrolet Niva depends on it.

To replace, you will need: a 12 hexagon, a 17 wrench, a rag and a container for waste material. Next, you need to unscrew the filler plug, and then the drain.

When the liquid has come out, clean the holes with a cloth and pour the cleaning liquid up to the top.

How much oil do you need for a dispenser?

If the car is new, the oil should be changed after 50 - 70 thousand km. If the mileage is over 120 thousand km, the replacement in the distributor must be carried out at least every 45 thousand km.

In order for the car to last longer, it is better to do it a little more often, a lot of dirt collects in the waste oil, which creates friction and, accordingly, the parts wear out faster.

It is optimal to change the oil after a trip, when the dispenser is warmed up and the fluid becomes more fluid. Need to prepare necessary tool: hexagon for 12, wrench for 17, container for working off and a rag.

Place the machine on the inspection hole and unscrew the drain plug, substitute the container and wait until all the waste liquid comes out. Unscrew the filler plug and check all valves for contamination. Clean the plugs and holes, pay special attention to the magnet, inspect how much dirt is, it is possible that replacement should be carried out more often if there is a lot of metal shavings. After that, pour new oil into the distributor in the amount of 0.8 liters.

The transfer case in the Niva is a very important mechanism for an SUV, how the car will cope on difficult road sections depends on its operation.

Axle oil change

In order for the Chevrolet Niva to work flawlessly and for a long time, it is necessary to monitor all process fluids and replace them in a timely manner.

The required volume in the rear axle is 1.3 liters. To change the oil in the front axle, 1.15 liters are required. Better to change at the same time.

Under normal operating conditions of the car, replacement will be required every 40 thousand km. If the car often works off-road and carries heavy loads, the procedure should be carried out more often.

The front and rear axles in the Niva are very important elements of the entire mechanism. Liquids need to be selected in accordance with the season, on synthetics in the cold season, the car simply will not start. Better to choose mineral or semi-synthetic materials.

Two bridges will require 3 liters of fluid. Car preparation is the same as when changing transmission oil.

Before starting work, you need to warm up the machine and make the liquid more fluid, prepare the tool: a 12 hexagon, a container, a filling syringe, a 17 wrench, a rag.

Then everything is according to the instructions: unscrew the plugs, drain the waste material, pay special attention to the magnet in the drain. A large amount of dirt and shavings is a sign that the procedure should be carried out more often. Thoroughly clean all openings of the axle oil reservoir, this can be done with a normal rag. Fill in liquids and let the car run, if the oil is gone, you can add the required amount.

The procedure is simple and even a beginner can handle it, but if you have concerns or just don't want to get dirty, you can contact the nearest car service. This must be done regularly and do not forget, each fluid change must be recorded and the mileage at the current moment must be noted. If you follow the manufacturer's recommendations exactly, there will be no problems with the SUV.

Periodically during operation, according to the technical inspection card, it is necessary to change the oil in the transfer case on the Vaz Niva 2121 and 2131. To carry out repair work, prepare a standard set of tools, then drive the car to the inspection pit, overpass or lifts. Also, before replacing, the oil in the distributor must be warmed up, for this it is worth driving at least 10 km.

Work

Then do the following sequence of actions:

Prepare an empty container, then use a nineteen hexagon wrench to unscrew the drain plug of the transfer case housing and drain the oil. Be careful when working, as the oil is hot.
There is a magnet on the drain plug to collect metal shavings and other debris, clean it, then screw the plug back into place.


Now, with a twelve hex wrench, unscrew the filler cap of the dispenser and fill it with a new one with a technical syringe transmission oil.


The oil must be topped up until it matches the lower edge of the filler neck. Then we twist the cork.
And in the final step, you need to clean the breather, which is located on the side of the rear propeller shaft.

Since the distribution box contains rubbing elements, wear products inevitably appear in it over time. If you do not change the oil in the transfer case in a timely manner, its resource will be reduced. Oil loses performance and small particles increase gear wear.

How often to change

There are several different types of transfer cases, and depending on the type of mechanism, the frequency of replacement in them can vary significantly. Usually this information is contained in the technical documentation for the car and varies in the range from 50 to 100 thousand kilometers.

In addition, the operating conditions affect the period. The distribution box of a car that drives on public roads experiences much less stress than that installed on a car that constantly moves off-road.

How to choose

Two types of fluid are poured into the distributor: transmission oil or ATF fluid. On cars with automatic transmission, ATF is usually poured into the transfer case, with manual transmission - the transmission. In this case, often, the fluids must match, or be completely compatible.

This is due to the fact that usually the connection between the transfer case and the box is made by a single shaft, or one is attached to the body of the other. When mixing liquids, this will avoid the formation of emulsion, foaming and other side effects.

For most modern cars with a dispenser, the manufacturer recommends the use of gear oils of the GL-5 class. They protect hypoid gears well, are designed to work in the most loaded mechanisms and contain extreme pressure additives.


The viscosity characteristics of oils play an important role. Let's analyze the meaning of the numbers using the example of 80W90 oil:

  • 80 - viscosity at low temperatures
  • W - all-season
  • 90 - viscosity at high temperatures

If ATF is used, it is better to fill in the original fluid recommended by the manufacturer, or an analogue with appropriate approvals.

What and how much to fill

The following table will allow you to choose oil by car make and find out how much is required.

Check level

On most cars, viewing windows are not provided for checking the oil level in the dispenser. Level control and replacement is carried out through the filler hole.

To check, it is necessary to place the car on a flat surface and unscrew the filler bolt, or the control bolt, if any. Usually they are made for four or hexagon, or for a wrench.


A level just below the filler / control hole is considered normal.

The need for replacement is determined by the intake of a small amount of oil. This can be done with a syringe with a flexible tube at the end. Black, cloudy, with traces of depletion, must be replaced.

How to change

The replacement procedure itself is simple, but often complicated by the fact that access to the filler hole is difficult. A lift, viewing pit or overpass is also required.

Some motorists make their own drain hole in the distributor in order to facilitate the procedure for a complete oil change as much as possible. To do this, a hole is drilled at the bottom point for the plug and a thread is cut.


You will need:

  1. A special syringe for pumping technical fluids (cost 500-800 rubles). You can use a medical one, but due to its small volume, the replacement process will be significantly delayed. What is more expensive - time or money, you decide.
  2. Transfer oil (transmission / ATF) recommended by the manufacturer or having an appropriate specification.
  3. Gasket sealant, degreasing liquid.

To prevent dirt from getting inside the dispenser, clean the surfaces before unscrewing the plugs.

There is a drain hole

If your car is equipped with a drain plug, you need to unscrew the bolt and wait until the oil drains out completely. The magnet on the plug should be cleaned of debris. Degrease the drain hole and plug, apply a coat of sealant and screw the plug into place.

Use a syringe to fill the dispenser with oil until it flows over the edge of the filler hole, then screw the cap back onto the sealant.

No drain

In this case, all operations are performed through the filler hole. A syringe tube is inserted into it and the oil is pumped out as much as possible. The procedure for adding new oil is the same as described above.

Changing the oil in the Renault Duster razdatka

Axle oil change

What and how much oil to fill in the bridge and the Duster 4x4 razdatka

According to the manufacturer, the oil in the transfer case and axle cannot be changed and is filled for the entire service life of the vehicle.

But underfilling the oil in the distributor and the axle is a fairly common occurrence on Renault Duster.
In this case, only 2 cm was missing to the level, it is not scary, but to calm it down I had to change it.

Since it is not clear what kind of oil was filled, I had to play it safe and buy a new gear oil Total Syn Fe 75W-90, Renault recommended oil, solidifies at temperatures below 50 degrees.

To change the oil in the razdatka and the Renault Duster bridge, there will be enough 1 liter.
In this report, it took 1 liter and 50-100 grams, this is when filling to the maximum, to the level of the drain holes and taking into account the complete draining and flushing of the rear gearbox and distributor.

  • We start with the rear gearbox
  • You don't have to lift the car, if you lie on the ground, then there is enough space.
  • Unscrew the drain plug (bottom) with a hexagon
  • Drain the oil, the oil will be black enough, this is normal.
  • We twist the plug back, do not forget about the gasket

The oil will not drain, so you can use the vacuum hose to drain the oil completely.

The hose is just vacuum, because the walls are not compressed. We insert one end of the hose into the filler hole of the gearbox, resting the hose against the bottom, the other end of the hose to the vacuum pump (or create a vacuum with our lungs), the hose is taken long so that oil does not get into the pump or swallow it.

You can also flush the gearbox and drain the flushing fluid completely in this way. The oil drains out of the distributor well, you do not need to rinse it.


It is convenient to pour oil into the rear gearbox with the help of such a device.


We push the hose and pour new oil into the filler hole (upper), the oil must be poured to the very edge of the hole.



We twist the upper plug on the gearbox and wipe the traces of oil with a rag after replacing

Moving on to the transfer case

We remove the right front wheel (passenger side), you can simply turn it out if it is convenient.

The transfer box is located on the passenger side, right behind the wheel. See the photo below.

We find the filler hole, it is also the control one.


Transfer case oil level is normal.

To access the drain plug, you will have to partially remove the protection by unscrewing the six mounting bolts so that the protection hangs only on the front ones. The drain plug of the transfer case is indicated by an arrow.

The oil drains out of the distributor well, you do not need to rinse it.


We drain the oil, tighten the drain plug. Putting the protection together in the reverse order.

Oil was poured everywhere exactly along the edge of the filler hole (it even poured out a little).

The control and filler hole of the box is located in the same way as the dispensing hole, but on the left side.

In the box, the oil did not change, only the level was checked - almost flush with the edge.
