What are the best oils for the VAZ 2103 engine. Changing the oil in a VAZ engine: what you need to know for self-service. What kind of oil should be poured into the Lada Granta?

The VAZ 2103 engine is a classic power unit, part of the line of engines developed and produced by AvtoVAZ OJSC.

To summarize, we can say that all of this family (2101 - 2130) are developed on the basis of a deeply modernized FIAT-124 engine. The changes carried out by domestic designers concerned the upper camshaft and cylinder center distances.

It was these changes that made it possible to modernize the engines more than once in the future, without stopping their mass production. From other power units of this model range(except for “”) the 2103 engine differs in that the timing shaft is driven by a steel chain.

Specifications

The power unit was installed on VAZ cars: 21023, 2103, 21043, 21053, 21061, 2121.

Description

The VAZ 2103 engine is manufactured using a “high” cylinder block (215.9 mm instead of 207.1 mm), which made it possible to increase its working volume to 1.5 liters and install a crankshaft with an increased piston stroke.

The unit is a classic version of an engine with an overhead gas distribution mechanism.

The camshaft is driven by a chain drive, and there is no chain tensioner. Therefore, chain tension must be checked and adjusted regularly. In addition, the valve clearances also need to be adjusted, since the gas distribution mechanism does not have hydraulic compensators.

• The cylinder block is made of cast iron, and its head is cast from aluminum alloy. The camshaft is made of steel and differs from other models by the presence of one untreated journal, which is shaped like a hexagon.
• The carburetor, which is installed on the VAZ 2103 engine, is equipped with a distributor with a vacuum ignition timing regulator. After the advent of injection power units, a modified cylinder head with a corresponding gas distribution mechanism began to be installed on the engine.
• To operate the water pump (pump), a drive with a V-belt having a cross-section of 10x8 mm is used.
• Oil is supplied from the crankcase to the internal channels of the cylinder block and to the friction pairs using oil pump, located in the crankcase of the power unit.
• The 2103 engine was equipped with both classic and contactless system ignition

Maintenance

The VAZ 2103 engine has a high degree of unification at the level of parts and assembly units, and therefore its repair, associated with the replacement of components, does not cause any difficulties.

Like all VAZ power units of that time, VAZ 2103 engines require quite complex and labor-intensive maintenance. When conducting routine maintenance necessary:

1. Every 10-15 thousand kilometers, check and, if necessary, adjust: tension of the timing chain; valve clearances in the cylinder head;
2. Clean and adjust the carburetor regularly.
3. Change after every 10,000 km motor oil.
4. Check the engine regularly for coolant and engine oil leaks.

According to numerous owners of cars with VAZ 2103 engines, this power unit is one of the most unpretentious and reliable among all engines of the classic engine family.

The only condition is careful regular maintenance and operation in the modes recommended in the vehicle’s operating manual. If this requirement is met, the service life of the 2103 engine can reach 300 thousand km.

Malfunctions

Engine 2103 is characterized by the same malfunctions as other classic VAZ engines. The most common:

There are also other malfunctions when operating VAZ 2103 engines. In general, it is better to diagnose engine malfunctions in a specialized service station.

Tuning

You can add power to the 2103 motor in various ways:

The easiest way is to bore the cylinders to a diameter of 79 mm. This will increase their total volume to 1.6 liters. Installing pistons with a diameter of 79 mm allows you to increase power to 75 hp. With. In this case, the torque will be 115 Nm at 3,000 rpm.

1. A further increase in power can be achieved by increasing the piston stroke to 84 mm. For this, TRT pistons and a crankshaft from the VAZ 2130 are used. This crankshaft is usually used in cases where they want to increase power and torque at low and medium speeds. At the same time, engine power will increase to 80-85 hp. With.
2. There is a more complex tuning option, in which: the channels of the cylinder head and intake manifold are bored and polished; select the appropriate camshaft. Correctly selected parts can increase engine power up to 100 hp. With.
3. Installing a 0.5 bar compressor together with a modified cylinder head makes it possible to increase power power plant up to 125 l. With.
4. More expensive ways to increase the power of the 2103 engine are also possible, but the price of components and payment for work associated with modifying parts, assembling the engine and adjusting it may exceed the cost of both the engine and the car as a whole.

Do I need to add oil to the engine? The person who asked such a question can be immediately sent to hell, or considered to be completely ignorant of technology or just an idiot.
The answer is clear - there must be oil in the engine. What kind of oil to pour into the VAZ 2103 engine?
When is the oil change done in a VAZ 2103 engine?
How to change? To rinse or not?
Not every driver can answer these questions. But these instructions for changing the oil will completely satisfy you with their answers to the above questions.
Here you will find everything you need: oil change videos, detailed description the process of changing the oil yourself, tips or “how to do it better” and so on. So let's get started.

Types of oil oil

Selection of engine oil for VAZ 2103:

• Mineral motor oil
• Semi-synthetic
• Tool
• Oil change
• Drain
• Flushing
• Replacing the filter
• Fill
• Starting the engine
• Brief Conclusion

Choosing engine oil for VAZ 2103

What to look for when choosing oil? Correct VAZ 2103, and any other, means filling in the same type of oil as it was from the same company, preferably.

This is done because the engine is already accustomed to working with this oil and there is less chance of harmful deposits, precipitation and the like. But you can switch to another, say, higher quality oil.
So which one should you choose?
As for the manufacturer, there are no special rules. It all depends on the desire and price of the oil.
If finances allow, it’s better to buy more expensive ones, because more expensive means better quality. And the higher quality the oil, the later it is to overhaul the engine.
You can buy oil domestic brands or foreign ones - but not a cheap fake - it will only make things worse!

Mineral motor oil

So:

• Will it fit? mineral oil(simply “mineral water”) for the VAZ 2103? Yes, it will do. After all, this car was manufactured back in Soviet times, and then, perhaps, this was the only oil they used.
  We went and were happy.
• But “can” does not always mean “necessary”. Yes, it is permissible to use a mineral water engine, but it is not recommended.
  Why? Time will tell - or rather, time will pass, winter will come, frost will hit and your engine, when you try to start it, will show you, excuse me, no idea!
• Yes, yes, and all because mineral oil has a very bad property - it freezes at low negative temperatures. This is not the only negative property.
  Mineral water also leaves deposits on engine parts and also requires frequent replacement.

Semi-synthetic

So:

• This oil has already improved properties and characteristics in comparison with mineral water. The service life of semi-synthetics is noticeably longer; accordingly, it will better retain its properties up to necessary replacement by mileage.
  Less negative impact on the engine than mineral oil.
• The price of such oil is not that high. It is easy to buy in almost any store.
  In a word, it is a universal oil, which is often used in Zhiguli cars.

So:

• This oil is by far the best there is. It has become widespread due to its high performance properties and good ability to maintain the functionality of all engine parts.
• Also, synthetics hold up well at high negative temperatures, which is extremely useful under harsh working conditions.
• But still, synthetic motor oil is not recommended for use on such cars for several reasons. The main one is expediency.
  The whole point is that the car was developed a very long time ago, when such oils did not yet exist.
• And engine parts can easily run on both mineral water and semi-synthetic. And the price for synthetics is simply astronomical.
  So there is simply no need to pour such oil when changing the oil in a VAZ 2103.

Let's sum it up! The generally accepted opinion is that a semi-synthetic oil labeled 10W-40 or similar in properties is best suited for a VAZ 2103 car.

Oil change intervals and vehicle preparation

How often is the engine oil changed on a VAZ 2103?
Let's pay attention to a few points:

• If oil was added after overhaul engine, it should be changed after 1 thousand kilometers. This is done because during break-in, intensive wear of engine parts occurs - the connecting rod-piston group and other parts.
• The usual oil change on Zhiguli engines is carried out during the period of 8-10 thousand kilometers or after 2 years, if the car has not been used, the lubricant will simply lose its properties.
• If mineral motor oil was poured into the engine, it should be replaced earlier.
• Unsuitable oil has a dark color - black, gray. This indicates that it contains a large amount of carbon deposits and other harmful substances and signals the need for replacement.

What does preparing a car for an oil change include?
Let's look at it in order:

• Of course, purchasing oil and filter.
• The condition of your car's engine is satisfactory. If the engine is “consuming” oil or if traces of leaks are visible on the block, then it would be advisable to first repair the engine to eliminate all the shortcomings.
• Warming up the engine. Hot oil drains better - an indisputable fact.
  Before changing the oil, you should drive it for about 10 kilometers.
• Find a hole or overpass. If you have a hole in your garage, that's just great.
  If not, then you will have to work hard and find these objects. They are the most convenient way to change the engine oil of a VAZ 2103.

• And, of course, a tool.

Tool

What you need to change the oil.
Here's what:

• 12mm hex or 17mm wrench
• Watering can for convenient oil filling

• The container for draining the oil is an unnecessary old bucket, but intact.
• Oil filter puller

• Knife
• Screwdriver
• Rag

That's all the accessories. Let's start replacing!

Oil change

So, after selecting high-quality oil, purchasing, eliminating all oil leaks on the engine, preparation the necessary tool After warming up the engine, you can change the engine oil.

Drain

Drain the old oil.

So:

• We climb under the car and find a drain plug in the pan.
• Usually it is made with a hexagon, but there can be another one - usually with a 17 key.
• Unscrew the drain plug.
• We substitute a container for oil.
• Next, you need to wait until all the oil drains from the engine.
• Then screw the drain plug back into the pan.

Note! Oil can burn your hands, so be careful. It is best to use thick rubber gloves - your hands will remain safe and clean.

Flushing

Often this item is simply excluded from the list. But in some cases it is better to wash it.

So:

• If produced for a different type. Simply put, there was mineral water, fill it with semi-synthetic, which means we do a flush.
• Change the markings of the oil being poured.
  Let’s say semi-synthetics remain, but the new one has a different designation, and, accordingly, different performance indicators. Let's do the washing!
• And the third option is if the engine has not been started for a long time.
  The oil has left deposits on the walls of the parts and they need to be washed off. We wash the engine.

Washing can be done in several ways.
Here are some of them:

• Five minutes. The liquid is simply poured into the engine for 5 minutes and then drained.
  This method is not recommended simply because it makes no sense. This type of supposed flushing simply thins the oil and allows it to drain better and faster from the engine, but does not flush it!
• Special fluids for flushing or flushing oil. Here is the procedure for flushing the engine in this way.
• After draining the old oil, flushing oil is poured into the engine. This is done through filler plug in the cylinder head cover.
• Then the engine is started and allowed to run at low speed for about 10 minutes.
• The next step is to drain the flushing oil.
• The engine is flushed and ready to be filled with regular oil.

Advice! Flush the engine only in the cases listed above. If you fill in the same oil as you had before the change, then flushing will even be slightly harmful to the engine!

Replacing the filter

After washing, and if we change the oil without it, then after draining the oil it is necessary to replace the oil filter. Instructions for replacing the oil filter.

So:

• Removing the oil filter may not require anything. Usually it is simply twisted by hand.
  For convenience, you can use a rag or gloves.
• If you cannot twist the filter, then you will need to use a special puller.
• There are pullers different types, so let's say in general outline. Clamp the filter in the puller and turn it in the unscrewing direction.
  Then you can twist it by hand.
• If even with a puller it is not possible to remove the filter, then it is simply pierced with a screwdriver and unscrewed in this way.
• Pay attention to the seat for the filter. It happens that a rubber sealing ring from the old filter remains on it.

• This ring must be cleaned with a knife and the seat wiped with a rag so that no debris remains there.
• After preparing the seat, you need to pour a little oil into the new filter and also lubricate the rubber O-ring.

• Remember - the filter can only be screwed back on by hand! Otherwise, you simply won’t be able to unscrew it later.
• The filter has been changed.

Advice! Don't forget that in oil filter There are also oil residues. Do not expose your face or hands - you risk getting burned and dirty!

Fill

Let's start filling the oil:

• Open the hood.
• Unscrew the filler plug. As already mentioned, it is located in the cylinder head cover.
• Next we need a watering can. We insert it into the filler neck.
• Add oil. When filling the oil, it is important to monitor its level in the engine.

• To do this, take out the oil dipstick and wipe it. Then we lower it into the block again, take it out and look at the level.
• The oil level on the dipstick should be approximately halfway between the two minimum and maximum marks. Do not allow the oil to reach the maximum - this will put unnecessary stress on the engine seals and make it more likely to leak.

• After starting the engine, you will need to add oil to the level.
• Screw the filler plug back. Pay attention to the condition of the plug.
  It should fit tightly. If its condition is not satisfactory, then oil will leak from under it and it will tremble and make sounds that will irritate you while driving.

Starting the engine

After changing the oil, you need to start the engine and check its operation:

• A few seconds after starting, the oil level light should go out.
• The engine may be noisy at first, but it will clear up later. It takes time for the oil to get into the system.
• While the engine is running, check the tightness of the drain plug. If it is not tightened properly, oil will leak from there.
• After running the engine for a few minutes, turn it off and check the oil level. Top up if necessary.

Brief Conclusion

A short final note:

• Monitor the condition and cleanliness of your car engine.
• Change the engine oil on time!
• Do not break the thread when tightening the drain plug - this sometimes threatens to replace the pan.
• Don't overlook the advice you've seen here.
• Choose an oil that has already proven itself in good light. Beware of cheap imitations.
• Watch the video on changing the oil to make it even clearer.
• We hope that this article, along with supporting photos, will help you.

Keep an eye on the condition of your Troika and it will serve you for many years!

By analogy with previous modifications of the line ICE engine VAZ 2103 retained the overhead camshaft arrangement. The engine power has been increased, the attachment is rotated by a belt, the chain remains only on the timing sprocket.

Technical characteristics of the engine 2103

In the third ICE 2103, the manufacturer AvtoVAZ returned the original cylinder diameter of 76 mm and increased the volume of the combustion chamber, therefore technical specifications motors look like:

Design features

The engine diagram has the following nuances:

• camshaft from 2101 – one journal between the cams of the second cylinder is unprocessed (hexagon);
• cylinder head – inside the combustion chamber there is a 2 mm stage made by milling;
• drive - timing chain, pump and generator - 8 x 10 mm belt, 944 mm long;
• crankshaft from 2101 – 40 mm crank radius;
• The engine volume has been increased compared to the previous version 2101 - the block height is 8.8 mm larger, the piston stroke has increased.

For the domestic “classic” VAZ, there are general standards for what kind of oil to pour into the engine - 5W30/5W40 or 10W40/15W40. The cooling system here is combined (spraying and lubricant supply under pressure).

In this internal combustion engine, the intake manifold has a longer baffle to improve the stability of idle speeds, so the part is not suitable for earlier versions of engines. The exhaust manifold remained unchanged, allowing tuning through the use of a direct-flow muffler to increase the car's drive power.

Advantages and disadvantages

The main feature is the timing drive, so the 2103 engine must be serviced every 10,000 km. The camshaft wears out intensively, reducing engine performance. This version of the internal combustion engine manufactured by VAZ is characterized by all carburetor malfunctions.

But for these engines a major overhaul is provided, since they are serviceable; the manufacturer’s plant has repair kits for pistons and rings

What cars was it installed in?

The 2103 engine was created for the corresponding AvtoVAZ model, and later began to be installed on other cars of this manufacturer:

• VAZ 21023;
• VAZ 21043;
• VAZ 21053;
• VAZ 21061;
• VAZ 2107;
• VAZ 2121.

Due to technical features, the 2103 engine is always located longitudinally, so it is not used in front-wheel drive models.

Maintenance schedule

The official manual explains the design of the internal combustion engine and the timing of replacing consumables when servicing the engine:

Thanks to its simple design, oil changes and even major repairs can be done yourself. In Soviet times, motorists practiced engine modernization, the options for which are discussed below.

Malfunctions: signs, causes and solutions

The following breakdowns are typical for the 2103 engine manufactured by VAZ:

Attention: When the timing chain breaks, the engine bends the valve, so the tension and general condition of the links should be periodically checked.

Tuning options

The most popular tuning types are:

• boring the cylinder diameter by 3 mm to increase the volume (for serial piston 2101 or 2106);
• increasing the piston stroke to 84 mm and using a crankshaft from 2130;
• replacing connecting rods with parts 134 mm long.

Thus, the 2103 engine is qualitatively superior to the two previous modifications of the internal combustion engine of the AvtoVAZ manufacturer. The owner of a Zhiguli did not need to think about which oil to use, since the instruction manuals 2101 - 2103 are as similar as possible.

Substitution oil filter And oils in the engine crankcase

Since 1974 the plant VAZ advises a change oils create after 5000 km, but this depends on the operating conditions.

During the running-in process, despite the highest production standards and the most advanced technology for the production of engine parts, small particles of metal are separated, which are constantly washed away by the oil circulating in the system.

The oil is also contaminated by penetrating dust particles. The bulk of these particles settle in labyrinths oil filter, but some of them still circulate in the system. In addition, additives that improve the oil evaporate over time, the oil loses its valuable properties, and this immediately affects the performance of the engine.

On engines Zhiguli cars a full-flow narrow filter is installed oils. Changing the oil in the VAZ 2115 gearbox - detailed. The very word “full flow” means that, unlike the lubrication systems of other cars, where only part oils passes through a fine filter, all oil circulating in the system is cleaned. The filter provides good cleaning oils from mechanical particles and oxidation products.

For cleaning oils The filter design uses a paper filter element made of porous heat-treated paper. In order to increase the working surface of the element, the paper is specially bent into 180-184 folds.

Efficient filter operation— a reliable guarantee of long-term engine operation, therefore we draw your attention to the need for timely replacement filter.
Replacement operations oils and filters, for convenience, should be done in the garage on an inspection ditch or overpass to provide free access to the drain plug in the engine oil pan.

To successfully carry out this operation, like any other, prepare the necessary tools, devices and materials. Do not forget to check the suitability of the material prepared for pouring. oils season, remembering that summer oil is used at temperatures from 5°C and above, all-season oil - up to minus 20-25°C, and winter oil - from minus 25°C.

Quantity oils in the lubrication system - 4.2 l, however, it should be remembered that when changing oils For all VAZ models, it is enough to fill only 3.75 liters, since approximately up to 0.5 liters remains in the lubrication system when drained.

Oil filter must be complete with a rubber gasket.

Removal key oil filter

If everything is ready, the car is installed on an inspection ditch or overpass, secured with wheel chocks and a hand brake, you can begin the operation. Open the hood. Remove the oil filler cap to create normal atmospheric pressure in the internal cavity of the engine.

The fact is that when the engine is running, the mechanisms, heating up, displace excess air, creating a vacuum, which interferes with normal drainage oils. Unscrew the drain plug in the oil pan, having previously installed a bucket or other container to drain the used oil. oils. The container needs to be installed slightly back along the car from the drain hole, since it is located at an angle of 30° from the vertical.

The oil must be drained from hot engine, when the viscosity oils low. How much oil is in the VAZ/LADA 2103 engine. How much oil is in the VAZ 21099 gearbox and engine. The drained oil must be warm, the draining time must be at least 10 minutes. When performing this operation, be careful to avoid burns from the hot oil.

After the oil has drained, tighten the plug and unscrew oil filter. If you do not have a special key, this operation can be performed using a piece of sandpaper. Wrap the abrasive side around the filter and turn the filter counterclockwise.

If this method does not give the desired effect, do not be upset; pierce the filter housing with the firmware that is included in the small tool box. In the original version, the engine in the VAZ 2103 can produce up to 77 horsepower, this power is quite enough to accelerate a not so heavy car to hundreds in 16 seconds. By placing a tube or a key for turning out the spark plugs on the firmware rod for convenience, you will certainly move the “stubborn” filter.

This extreme measure can be applied, given that oil filter- one-time use.

Before installing a new one filter do not forget to check the position of the rubber ring gasket, which should be in the groove of the filter end. To prevent the gasket from moving during installation, lubricate it motor oil. When installing a new oil filter You should not use any tool, but rely on the force that can be provided by your hands.

Using a funnel (so as not to spill oil), pour 3.75 liters of engine oil into the oil filler neck. oils, corresponding to the season of operation of the vehicle. After a few minutes, when the oil has drained, check its level using a dipstick.

If upon inspection it turns out that the level oils above the “Max” mark, don’t be embarrassed, start the engine, after 3-4 minutes the oil will fill all its “containers”, and its level in the engine sump will become normal.

Before starting the engine, be sure to install the filler cap.

Some car enthusiasts sometimes use oils imported, for example, Shell or Esso. Changing the oil in the box for a VAZ 2101-VAZ 2107. When purchasing a mineral oil oils We recommend taking a look at esso extra oil. What you need to know to change the oil in a VAZ 2106 car. Recommended oils and their main characteristics, selection criteria. With a viscosity of 15w40, it is practically all-season. You can also try using semi-synthetic, but this is usually not recommended for older engines. In general, it is necessary to fill in the same oil as was previously filled.
