Which oil for the Chevrolet Niva gearbox should you choose?
The Chevrolet Niva is an all-wheel drive vehicle. Properly selected oil for the transfer case, as well as all axles of an SUV, guarantees long-term operation of all vehicle transmission mechanisms. Oil helps reduce friction, which means the period of wear of parts increases significantly. The table below shows the characteristics of filling fluids for the Chevrolet Niva, taken from operating instructions
When choosing transmission oil for a Chevrolet Niva SUV, you should follow the recommendations of the vehicle manufacturer. It is better to purchase gear oil in special auto stores. It is best to give preference to proven, well-known brands. It is important to pay attention when buying oil for what period of the year it is intended. There are oils for summer, winter, and all seasonal. Worth remembering! If the vehicle was purchased with mileage, then it is necessary to check the oil level.
It would also be a good idea to change all the oils.
Tips for choosing oil
As mentioned above, the purpose of this car is mainly for off-road driving. This can be understood by the connection between the gearbox and all-wheel drive. The car overcomes various off-road obstacles well and withstands various operating weather conditions well. All these factors affect the performance of the transmission. To maintain transmission efficiency and reliability, lubricants must be selected responsibly.
When choosing the best transmission oil for Niva-Chevrolet, you need to follow the following recommendations. First you need to refer to the vehicle operating instructions provided by the manufacturer. Also, you should not chase the cost of oils; to a large extent, a high price does not always mean good quality. Sometimes it is influenced by the popularity of the brand - the greater its popularity, the higher the cost of the product provided. It is also important to change the oil correctly and on time, this extends the life of the transmission, and the ride itself becomes more comfortable. That is, when buying a used car, you need to take into account that it may have traveled more than one hundred kilometers. Therefore, you need to be careful when changing the oil and change it more often than on new cars. It is advisable to check the level 1-2 times a week so that it does not fall below normal - this can lead to serious deviations in the transmission.
Chevrolet Niva filling volumes
The first question before changing the oil in the Niva transmission is how much oil should be poured? The answer to this question will be a table of car refueling volumes. Here you should pay attention to the volume of oil in the gearbox housing, in the transfer case and in the rear and front axle housings. In total you will need 4.84 liters, so you can safely take a 5 liter canister of oil.
Removal
If you do the work yourself, then you need to do the following:
- Removing the wheels
- There is oil in the crankcase that needs to be drained, disconnect the driveshaft from the front axle gearbox
- We unscrew the nut and remove the bolt that secures the left gearbox bearing cover to the suspension cross member.
- We remove the existing drive from the wheel and unscrew the nuts that secure the bearing cap
- We take the steering knuckle and turn it, pulling the drive from which we disconnect the gearbox and then remove it.
We carry out the installation in the reverse order, after which we fill the lubricating fluid to the required level.
What kind of oil should I pour into the Chevrolet Niva transmission?
The choice of oil for the transmission of a Chevrolet Niva car is carried out on the principle of inadmissibility of mixing oils whose compositions are different. Regarding the viscosity characteristics of oils, it is better to give preference to the use of the following oils:
- 75w-90;
- 80w-85;
- 80w-90.

Lubrication
On previous versions, drivers encountered problems with the lever's operation. It was possible to accidentally engage reverse gear instead of fifth. This issue has now been fixed. The solution was found in the form of installing a blocker, which is located at the end of the traction fork.
Now, to engage reverse gear, you need to squeeze the clutch and only then move the lever to position R. In this case, the locking stop drops below the special lining. In order for the mechanism to work properly inside, when the speed is turned on, constant lubrication occurs due to the splashing of oil. Therefore, to prevent oil leakage from the transfer case and dirt and dust not to get inside, the landing spots of the primary and secondary shafts are sealed with oil seals.
Changing the oil in a Chevrolet Niva gearbox
To change the oil in a Chevrolet Niva gearbox, you will need the following tools:
- steel hex key 12;
- wrench 17;
- container for draining used lubricant.
The sequence of actions for changing the oil in the Niva gearbox is as follows:
- Place the car over an inspection hole or drive it onto an overpass for ease of work. Before draining the old transmission oil, it is necessary to warm up the engine . This is necessary in order to drain the oil from the box as much as possible and without residue.
- Lower yourself into the inspection hole and place a container under the drain hole, taking into account the bend of the exiting stream. It is convenient to use a funnel.
- Clean the locations of the filler and drain plugs on the gearbox, as shown in the photo above.
- First, it is better to unscrew the filler plug, and then the drain plug using a hexagon.
- Now you need to wait until all the used oil has drained to the last drop.
- The drain plug has a special magnet to which all metal shavings are attracted. If there are steel particles on the plug, they must be removed. And another important point from a diagnostic point of view - the more of these particles are present on the cover, the less the gearbox will last.
- When the old used oil is glass, you need to screw in the drain plug and start flushing the crankcase. To do this, you need to 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 neutral in the transfer case and change gears with the clutch.
- Next, the flushing liquid is drained in the same way and new oil is poured in its place in the required volume.
- After filling the oil, you need to check its level on a level surface and start the engine. to let the engine run in first gear for 2-5 minutes After this, the oil level is checked and if it has dropped, then you need to add a little more.

Transfer case
This is another important transmission unit of the Chevrolet Niva. It includes a range multiplier and a lockable center differential. The transfer case also changes the amount of torque, but not in the same way as the gearbox. In addition, it distributes it between the axles, front and rear, maintaining a 50:50 ratio. The differential is locked to improve maneuverability if road conditions are very difficult.
The transfer case (in the picture its lever is 2) can be switched similarly to a gearbox, only the purpose of the lever shifts is completely different. There is a neutral position (NII–V). There is a high gear (HI) used for normal road conditions, with the differential unlocked. If it needs to be blocked, transmission (HIV) is activated. In difficult areas, the lever switches to LIII if the differential does not yet need to be locked. If it’s really difficult to drive, you need to switch to LIV, blocking the bridges between them. The wheels then rotate at the same speed.
You can switch from the Low position (L - low gear) to the High position (H - high gear) while driving. In this case, you should squeeze the clutch twice, because the transfer case does not have synchronizers. Switching from H to L positions is only possible after the vehicle has stopped. In addition, you cannot lock the differential at high speeds, as you can lose control of the car when cornering. The transfer case uses the same gear oil that is used for the gearbox.
Changing the oil in the transfer case of a Chevrolet Niva
As for this car model, the oil needs to be changed every 50-80 thousand kilometers . As soon as the car has traveled more than 120 thousand kilometers, the oil should be changed every 45 thousand kilometers. For information! The vehicle operating instructions contain information on the frequency of oil changes, which every car owner must follow. But it would be better 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, which over time leads to contamination of vehicle traffic mechanisms. This is why many car owners advise changing oils more often than indicated in the instructions. To ensure that the oil can be drained without problems, you should start replacing it after the trip. On the way, the oil has time to heat up, thereby taking on a more liquid consistency. Changing the oil in the transfer case is not as difficult as it seems at first glance. To replace it, you need to drive the vehicle into an inspection hole, or raise the car on a lift. You will need a container designed to drain the oil, as well as a rag to remove all smudges. Do not forget about the hex wrench (size 12), and you also need to have a refill syringe .
Draining and filling oil into the Chevrolet Niva transfer case
1. First of all, unscrew the drain plug. Then the oil is poured into the 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 dirt on the stopper should be cleaned. Afterwards the plug should be screwed back on. 4. The filler hole has a screw-on plug; it must be unscrewed. 5. Transmission oil is poured through a filling syringe. The ventilation valve is inspected and cleaned . 7. It is necessary to remember or note in a notepad the mileage that was on the car at the time of the oil change.
More details about changing the oil in the Niva transfer case are shown in the good video below.
Gear shift mechanism
This component consists mainly of a plate with cutouts that are rectangular in shape. All this is enclosed in the main body and is controlled by a lever.
The speed control mechanism is mounted on studs at the rear of the box. The neutral position is located between the third and fourth speeds and is adjusted by bars with spring guides. The plates are located in the guides to provide mechanical movement of the lower part of the lever.
The drive is based on three rods that connect to forks. Forward gears are engaged as a result of the forks entering special holes in the couplings. The rear entry is activated when the fork enters a special hole.
Changing the oil in the axles of a Chevrolet Niva SUV
For this procedure, it is recommended to follow vehicle maintenance, as well as the rules for repairing an SUV. Oil changes in vehicle axles should occur every 40 thousand kilometers (applies to cases of Niva operation under normal conditions ). If the car is operated in more difficult conditions, then the oil should be changed much earlier.
Preparation for changing the oil in Chevrolet Niva axles
Changing the oil in a vehicle's axles is identical to the procedure for changing the fluid in the transfer case. You should drive the SUV onto a viewing hole or onto a lift. The volume of oil required is the same as for the transmission. Before changing the oil, you should warm up the Niva. Next, you will need a 12-mm hex key, a 17-mm socket with a knob, a container for draining the used oil, and a rag. You should also make sure you have a refill syringe.
Stages of oil change in Chevrolet Niva axles
1. Unscrew the drain plug. 2. The bolt magnet is inspected to determine whether there are chips on it. If there are no chips, the bolt is screwed back in. 3. The used oil is drained into a prepared container. 4. The drain plug is screwed on and tightened - this procedure applies to the rear axle. 5. The filler plug is unscrewed. 6. Using a filling syringe , add oil in the required volume. 7. The filler plug is screwed in and tightened - again we are talking about the rear axle.
Changing the oil in the front axle of a Chevrolet Niva is shown in more detail in the video.
For details on changing the oil in the rear axle of a Chevrolet Niva, watch the video.
even an inexperienced driver can change the oil in Niva on his own if he follows all the necessary recommendations and the above. If you have any questions about changing the oil in the Niva transmission, ask them in the comments - our specialists will answer them.

Cooling mechanism
The Chevrolet Niva has a closed-type liquid cooling mechanism.
The cooling system includes:
- radiator,
- hydraulic pump,
- indicator,
- thermostat,
- electric fan,
- expansion tank,
- pipelines, etc.
The volume of the cooling system is 8 liters.
The expansion tank is located in close proximity to the brake booster. The marked indicators make it possible to quickly respond to a lack or excess of fluid. The main importance is attached to the tightness of the cooling system. Therefore, inlet and outlet valves regulate this value.
Aluminum radiator tanks are constructed of special plastic. The coolant is supplied through the expansion tank. The parameters for this type of liquid are Antifreeze A-40 M. It is recommended to use antifreeze containing additional components to avoid rust.
Lubrication algorithm
The car has a combined lubrication system. Lubrication is carried out under pressure and is distributed to the following mechanisms:
- main bearing,
- crankshaft connecting rod,
- camshaft bearing,
- oil pump shaft,
- helical gears of the oil pump.
Selected elements are lubricated by spraying.
The oil pump, consisting of one section and having gears in its design, is driven by two gears. Oil purification is carried out using an oil filter element. Oil system pressure is monitored using a light bulb. Signaling a decrease in oil pressure in the system. The lubrication system also includes hydraulic valve stems and a torque chain tensioner.
Preparing for replacement
The process of changing the lubricant yourself will take a little time - an hour or an hour and a half. But you need to prepare first. A set of tools, devices, and consumables is selected. You will need a 12mm hex key and a 17mm socket head, a container for waste fluid, dry rags, and sealant. For filling, you can use a special filling syringe (pump) or another device (funnel with hose). Copper sealing rings are placed on the crankcase plugs. Therefore, you need to prepare them in advance. Work is carried out with protective gloves.
