Niva VAZ 2121, 21213, 21214 gearbox oil

Changing the oil in the transfer case Niva 21214

The Niva 21214 car is distinguished by its increased cross-country ability on roads.
The car has an engine that has a volume of 1.7 liters, which complies with Euro-4 standards. The transmission system includes a transfer case with a crankcase ventilation system. All components on the VAZ 21214, just like on the VAZ 21213, are characterized by a long service life. It is important to take proper care of the automotive system and select high-quality oil for the Niva. The Niva SUV (VAZ 2121), which has all-wheel drive and is equipped with a manual transmission, is capable of producing 75 horsepower.

Selecting gearbox oil

Which oil to choose? Transmission oils come in a wide range. You should pay attention to fuel that has the following viscosity: 75W-90, 85W-90. In particular, you can choose Lukoil 80W90 gear oil (GL5 class). When operating vehicles in winter, you should purchase 70W-90 oil, as it has a low viscosity. Semi-synthetic options are also suitable for refueling Niva 21213. It is better to carry out replacement at a specialized service center.

How much oil to fill? Approximately 0.8 liters of oil must be added to the Niva distributor. 1.6 liters of transmission fluid is poured into its high-speed box.

Before choosing a transmission fluid, you should always carefully study its composition.

The need to change transmission oil

To change the oil on a Niva, the car must be warmed up (to ensure good fluid fluidity). The machine is placed on an inspection hole; a special container should be placed under the drain hole into which the waste liquid will drain. To open the drain and fill plug, you should use a hexagon. Also, as an additional tool, you will need a special syringe, which is used to fill the transfer case with fuel.

Changing the oil in the transfer case (Niva 21214 / 21213). Main stages:

1. The drain plug is unscrewed.
2. The remaining oil is poured into the container.
3. Any contamination on the plug must be eliminated.
4. The drain plug is screwed in.
5. The top plug is unscrewed to fill in new oil using a syringe.
6. The plug is screwed in.

The peculiarity of the gearbox is that it has a built-in magnet. Its function is to attract small metal debris that may be present in the fuel.

When replacing fuel, the crankcase must be flushed. This procedure helps to extend the operational life of the box. Flushing is required if the drained oil is heavily contaminated.

The frequency of changing fuel for the transmission is affected by the mileage of the Niva 21214 (21213) and the conditions under which it is used. When making frequent off-road trips, the need to change the oil for the transfer case and gearbox may arise up to 50,000 km.

The need to add a new lubricant to the box can be indicated by the fact that the gearbox began to overheat and characteristic noises appeared on its side during movement.

Fill

To fill in new antifreeze, you don’t have to do anything complicated.
You just need a special watering can. Many containers in which antifreeze is sold are not particularly convenient for pouring directly from them. Use a funnel to avoid spilling coolant. It is extremely important to know exactly how much antifreeze is in the cooling system. The coolant for the VAZ 2109 requires 7.8 liters. Therefore, antifreeze should be purchased in 8-liter containers.

1. Take a watering can and insert it into the neck of the expansion tank. This way you won’t spill precious grams of antifreeze.
2. Check that all drain plugs are securely tightened. Otherwise, the coolant will simply spill out onto the floor and you will have to buy new coolant.
3. Start gradually pouring in new antifreeze.
4. Stop periodically for 1-2 minutes so that the liquid has time to distribute throughout the system.
5. After filling the system, add coolant to the middle of the expansion tank level.
6. Next, the most important thing is to get rid of the air that has entered the cooling system.
7. Air accumulates in the upper pipe. To remove it, you just need to squeeze the upper pipe several times. Squeeze until you feel liquid appear inside.
8. Bleed the cooling system. To do this, use a screwdriver or a size 8 wrench to unscrew the clamp that holds the return hose to the CO expansion tank (return).
9. Now close the fitting with your finger, onto which the return line is put, so that air cannot escape from there.
10. Next you need to blow into the expansion tank. Just imagine that you are trying to inflate the tank like a balloon.
11. This will create pressure and coolant will begin to flow from the expansion tank into the CO, and excess air will escape through the return.
12. As soon as antifreeze begins to flow out of the return line, the procedure can be stopped.
13. Replace the return line and tighten the clamp.
14. Reconnect the negative terminal of the battery, close the cap of the expansion tank and check the quality of the work done.

It is not recommended to start active operation of the car without checking.

Changing the oil in the Niva 21213, 2121 gearbox

According to the recommendations of the VAZ manufacturer, the oil level should be checked after every forty to sixty thousand kilometers, but practice shows that it is better to do this at least twice as often. If, during inspection, you find that the oil is dirty and smells of burning, this means that it needs to be changed immediately. This procedure is easy to carry out yourself. Changing the oil in Niva 21213 is done in exactly the same way as in 2121.

Changing the oil in the gearbox.

The entire operation must be carried out in the inspection hole, and before the operation you need to drive eight to ten km so that the oil warms up.

If you are changing the oil for the first time, the first thing you need to do is find the filler neck. It is located on the left side and may not be immediately noticeable due to the gimbal. Do not confuse it with the technological plug, which is located on the right.

Having found the neck, take a 12mm hex and unscrew the drain plug.

Place a container near the neck and let the oil drain.

Next, clean the plug magnet from dirt and metal particles and screw the plug back on.

Now take the 17 key and unscrew the filler plug. Then, using a special syringe, fill the oil to the bottom edge of the hole and tighten the plug. All.

By the way, sometimes it happens that the box becomes clogged with metal shavings or the seals begin to leak. In such cases, you just need to add oil.

Power unit

The engine installed on the modern model of the Niva 21213 (214) car was inherited from its Soviet progenitor - the VAZ 2121, and in terms of fluid volumes they are almost identical:

1. Liquid cooling system. Filled with antifreeze in an amount of 10.7 liters with a freezing point not higher than -40 ° C. The capacity of the interior heating radiator is also included in this volume.
2. Crankcase. Motor oils are poured here, the brand of which depends on the operating conditions. Capacity: 3.75 liters, including oil filter filling.

The viscosity of the oil poured into the Niva engine must correspond to the outdoor temperature at which the car is operated. Possible modes and suitable oil brands are shown in the table:

When flushing the power unit during the process of replacing liquid lubricant, the same amount of flushing oil (3.75 l) is used, taking into account the size of the filter. Replacement is carried out after 8-12 thousand kilometers, depending on the quality of the oil. Flushing is usually performed after 3 engine lubricant changes. During operation, it is important to monitor the oil level in the engine crankcase using a special dipstick. If the level drops below the Min mark, it is urgent to add lubricant to the engine of the same viscosity as was previously filled.

Antifreeze needs to be updated at least once every 3 years or according to the degree of wear of the fluid. It is not recommended to dilute antifreeze with distilled water, either in winter or summer. In winter, the diluted liquid may freeze, and during the summer heat it may boil ahead of time, which will lead to overheating of the engine.

Lubrication system.

The lubrication system itself is also combined. The oil pump supplies oil under pressure to the bearings, crankshaft, and drive helical gear. Some parts are lubricated by splashing.

• The engine lubrication capacity is 3.75 liters.
• It is better to use synthetic and semi-synthetic SUPER oil. Its viscosity class: from -25 to 30, 35 - 5W30, 5W40; from -15- 45 - 15W 40; from -10- 45 - 20W 40.
• Transmission oils from Lukoil TM-4 are made on a mineral (80W 85, 80W-90) and semi-synthetic base (75W-90) and are off-season, high-quality, as they use additives from the world's best manufacturers. They are needed for gearbox housings (1.6 l).
• The same oil is used for the transfer case (0.79 l).
• For the front (1.15 l) and rear (1.3 l) axles, 80W 90 and 85W 90 are used.
• The 1.7 liter power steering requires Pentosin Hydraulic Fluid CHF115.
• The hydraulic front shock absorber (0.15 l) and rear shock absorber (0.215) are filled with Slavol-AZh or GRZh-12 ​​operating fluid.

High temperatures, constant loads and friction affect the service life and operating time of the motor. Without lubrication, gears and parts wear out quickly. In addition to cooling, it is possible to eliminate carbon deposits and microparticles.

Other liquids and fuels and lubricants

Every car enthusiast should know by heart the maximum fuel capacity of his car. The fuel tank of the VAZ 21213 has a capacity of 42 liters, including reserve. The reserve refers to the amount of fuel remaining in the tank after the yellow warning light on the instrument panel turns on. The reserve amount is at least 5 liters. The car must be fueled with gasoline whose octane number is in the range of 91-93.

The car has a number of refueling tanks that the owner must monitor during operation:

• brake system with expansion tank, total capacity - 0.515 l;
• hydraulic clutch drive with expansion tank - 0.2 l;
• 2 plastic tanks with a volume of 2 liters each contain a supply of windshield and rear window washer fluid.

The clutch release drive and brake system are filled with hydraulic brake fluid (the most popular is DOT-4). It should be changed at least every 3 years, because the liquid has the ability to absorb water vapor contained in the air. As a result, all steel parts of the system in contact with it begin to corrode, which leads to complete or partial failure of the brakes.

If there is a leak in the clutch or brake system, the level in the expansion tanks decreases, so constant monitoring is required over them.

The level of brake fluid in the reservoirs must be maintained no lower than the corresponding mark on the plastic body of the container.

Liquid or clean water for washing glass is added if necessary; in winter, a non-freezing option is required. Otherwise, the ice will not only destroy the tubes, but also damage the electric pump.

Various thick lubricants are also used for maintenance and lubrication of the Niva:

• Litol - a composition for lubricating highly loaded bearing parts;
• CV joints-4 - lubricant for the hinges of the front axle shafts and door opening limiters;
• ShRB-4 is designed for processing ball joints and steering rods.

The list of refueling containers is useful for novice car enthusiasts who bought a used car with a lost instruction manual. The operation of such a car should begin with the replacement of all fluids and oils.

Filling volumes for a VAZ 21214 car

It’s one thing to buy a car, and another to know and understand what to do with it: what to protect it from, when to “feed” it, how to operate it. No matter what kind of car you own, sooner or later you will need to refuel it. Today we will talk about the filling volumes of the VAZ 21214 and what to fill where.

First of all, let's talk about the fuel tank. Its volume in the VAZ 21214 is 42 liters (including reserve). Fill with gasoline with an octane rating of 91 to 93.

The fuel supply system is necessary to power the car engine, as well as its cleaning and storage.

The volume of the cooling system is 10.7 liters, which also includes the interior heating system. Fill in coolant whose freezing point is not higher than minus 40°C.

Cooling system - devices that provide supply of cooling medium to heated engine parts and removal of excess heat, i.e. maintaining the engine within the required thermal limits.
