How to replace coolant on a VAZ 2115i

When buying a used car, the new owner does not know what kind of fluid is in the cooling system of the internal combustion engine. This could be antifreeze or antifreeze, or even water (if you bought the car in the summer). Very often the coolant is diluted with water. When the radiator or cooling pipes leak, the owner is not too eager to invest in the car and adds water before selling the car.

How to check what kind of liquid is poured into the cooling radiator

Having bought a car secondhand, you just need to check the presence and level of coolant in the engine cooling system!

Its insufficient level can negatively affect the engine, not to mention the complete absence of fluid in the radiator. It is also worth checking if there are any leaks from the pipes, from the radiator, from the heater in the cabin.

If the old owner of the car forgot to say what liquid was poured into the radiator, you can try to determine its composition yourself. Antifreeze is almost always blue, antifreeze is usually green or red (red comes in different shades, even purple). If the color is unclear (rust color), then this composition must be changed. In general, after purchasing a used car, it is recommended to completely change the coolant.

The total volume of coolant in the 2115 system is 7.8 liters. However, when replacing, it is often possible to fill less than 7 liters.

As for what to fill, it’s better, of course, to pour in antifreeze; gas stations and oil stores sell proven brands like Felix. Can be green or red. But if you have been filled with antifreeze, and you want to add antifreeze, then you need to drain the antifreeze. Washing is not necessary. If you just add, then pour only the one that was poured before.

For example, a friend’s “tag” was filled with antifreeze, then the liquid leaked out a little due to careless use - the tank lid was simply not closed. We added blue antifreeze, bought at the nearest gas station, to a level between the minimum and maximum.

It is not so rare that cases occur when the happy owner of a passenger car drives his vehicle without even looking under the hood. Such exploitation is not permitted. For example, all the antifreeze may leak from the cooling system of an internal combustion engine, and then it will definitely be necessary to carry out a major overhaul of the engine. Therefore, it is necessary to monitor the presence of coolant (coolant) and know which one is poured into the system.

Is it possible to mix different fluids in the cooling system?

You should know that antifreeze is a type of antifreeze - it was specially developed for Zhiguli cars back in Soviet times. At that time, domestic antifreeze was not of good quality, and a better coolant composition for the new car model was simply necessary.

Car enthusiasts often ask whether it is possible to mix antifreeze with antifreeze. This issue is often discussed among car owners in real life, on various forums on the Internet. To be honest, they never came to a common opinion. One thing can only be said for sure - a catastrophe as such will not happen to the car. But still, it is not recommended to mix the compositions. It is better to adhere to the technical conditions and, for a certain car model, fill in the coolant that is recommended by the manufacturer for this brand of vehicle.

Flushing

Many experts agree that the system should be flushed before replacing the coolant. But how to do this and is such an event really mandatory?

If the coolant being drained shows signs of rust and contamination, then the system should still be flushed. This preventive measure will never be superfluous. Therefore, try to allocate some of your precious time to the procedure. The engine will remain grateful to you.

Expansion tank

The cooling system is washed quite easily:

• Drain the old fluid by unscrewing the drain plug;
• Fill the system with water through the filler neck;
• Distilled or boiled water can be used as a washing composition. Plus, there are special cleaning compounds. They are more expensive, but their efficiency is higher;
• Start the engine with flushing water inside and let it idle for about 30 minutes;
• Drain;
• If it is very dirty, repeat the procedure;
• Add new coolant to the system.

Coolant for VAZ 2114

What kind of coolant should I fill in the VAZ 2114? Maybe first you need to ask what kind of coolant is filled in at the factory? The Volzhsky Automobile Plant does not adhere to a single standard; in a VAZ 2114 car, with an equal degree of probability, there can be both antifreeze and antifreeze in the engine cooling system. But it is still recommended to fill in antifreeze, it is not for nothing that it was once specially designed for VAZ cars. The coolant must be changed periodically; this must be done in the following cases:

• 60 thousand kilometers after purchasing a new car;
• Every two years;
• If the coolant has a red tint or the liquid has become cloudy;

• If the coolant leaked and had to be diluted with water;
• When repairing, removing and installing an internal combustion engine (ICE).

In order to make a replacement, you need to know how much antifreeze there should be in the VAZ 2114 cooling system. According to the technical characteristics, 7.8 liters are poured into the VAZ 2114 internal combustion engine cooling system until it is fully charged.

The industry produces three types of ready-made antifreeze:

1. AK (concentrate);
2. A40;
3. A65.

Antifreeze AK is a concentrate and cannot be used in its pure form. The concentrate is diluted one to one with water, then the freezing point of the coolant will be −30ºC. A65 freezes at −65ºC, the most popular brand is A40 (freezing temperature −40ºC). It is the A40 brand that is most often poured into the Zhiguli BA3 2114.

There is a question that arises before replacing the coolant - whether it is necessary to flush the cooling system when replacing antifreeze. The answer is this: if the old coolant is not cloudy and no sediment in the form of insoluble flakes is observed in the radiator, it is not necessary to flush the system. But washing definitely won’t hurt, it won’t make it worse.

Optimal coolant option

When we figured out how to replace antifreeze

for VAZ 2110 (2112),

It is important to choose the optimal liquid option. Many car enthusiasts only use expensive antifreeze, considering it to be of higher quality. For VAZ cars, it is quite possible to use a cheap domestic product - antifreeze, the characteristics of which were developed specifically for these cars.

Coolant performs several functions in the operation of a car. The main tasks that can be accomplished with this substance are cooling in the engine operating system (injector) and engine cooling.

In this article we will tell you how to drain antifreeze
on a VAZ

and how to refill it, and also describe the reasons for leaks and drops in the liquid level.

The main actions that a cooling lubricant performs.

• Creating a low temperature in the operation of the gearbox, namely hydraulic fluid, which needs to be poured only into the automatic transmission.
• Creating a normal and stable temperature during engine operation (injector).
• Interior heating in winter. Filling with antifreeze keeps the car warm because it passes through the heater. Thus, the motor warms the liquid, and the fan carries it around the cabin.

Replacement in a VAZ car 2115

should occur once every two years or every 45 thousand km. After all, antifreeze, like any other substance, loses its qualities over time.

How to flush the cooling system

Before replacing antifreeze on a VAZ 2114, in some cases you should first flush it. Flushing is necessary when scale forms in the cooling jacket of the internal combustion engine, or when engine oil gets into the radiator (oil gets in when the cylinder head gasket is faulty). Cleaning the system is very simple:

• The old coolant is drained (how to drain antifreeze from a VAZ 2114);
• Water is poured in (preferably boiled or distilled);
• The engine starts and idles for 20–30 minutes;
• The water is drained and the system is charged with new coolant.

Why does it flow

Before draining the old fluid and changing

it, you need to understand why it flows out of your VAZ
2115
. Sometimes this is quite difficult to determine. Try to look through all the pipes, there are several places where the element can leak.

• Clamps - they may not be clamped well.
• The pipe itself, which can crack over time.
• Radiator due to mechanical damage.
• A pump or pump that wears out over the years in VAZ cars.
• Leakage from under the head.
• When the leak occurs directly into the car's cabin.

When any type of leak is detected, you first need to repair the area so that this situation does not recur, and then replace it.

Do-it-yourself replacement of VAZ 2114 coolant

Before replacing the coolant, the engine must first be cooled; work should be carried out on a cold engine. It goes without saying that the liquid should be purchased in advance. How many liters of antifreeze in a VAZ 2114 should be prepared for replacement? Although according to technical specifications the coolant should be about 8 liters, it is better to immediately purchase a 10-liter canister - in case it spills past the radiator.

On the VAZ 2114, replacing the coolant is easy. Let's consider an example of carrying out all operations on a car with an 8-valve engine.

We carry out the work in the following order:

• We unscrew the main engine protection. It is attached to the bottom of the engine compartment using four fasteners. Accordingly, if the protection is not worth it, then there is no need to turn it away.
• We remove the protective cover, which is located under the engine in the front part of the body.
• Remove the expansion tank plug.
• In the cabin, fully open the heater tap. This must be done so that when draining the coolant does not remain in the heating system.
• Prepare a container for draining the coolant. It is better to take a wide dish, for example, a basin. In this case, the coolant will not spill past.
• We find the drain plug on the radiator; it is located at the bottom near the generator. Before draining the radiator, you should somehow protect the generator from liquid getting on it.
• Drain the contents of the radiator.
• In order to get to the drain plug in the cylinder block, remove the ignition module. It is secured with three bolts.
• We remove the unscrewed module to the side; under it there is a drain plug. Unscrew it and drain the old coolant.
• We wait 10–15 minutes until everything merges.
• We tighten all the plugs.

How to add antifreeze to the cooling system? We place a funnel in the expansion tank and carefully pour the contents out of the canister, trying not to spill it past. After filling, we install all the removed parts in place. Then we start the engine and begin to warm up.

It should be noted that there is a high probability of an air lock forming in the cooling system, so it may not immediately enter the system. The volume of VAZ 2114 coolant is approximately 8 liters. Be guided by the amount of liquid remaining in the canister. If a blockage occurs, you should remove one of the hoses that go to heating the throttle valve and try to compress and release the upper radiator pipes. Antifreeze must pass into the system, making room for new fluid. There should be about two liters left in a ten-liter canister after all procedures.

Some tips

1. Replacing antifreeze on a VAZ 2114 is carried out on a cold engine. It is not recommended to perform work on a hot internal combustion engine - there is a risk of burns.
2. Before draining the coolant, protect the generator from moisture.
3. When pouring antifreeze, you need to ensure that the entire required volume of liquid enters the cooling system. If it is less than required, the possibility of engine overheating cannot be ruled out.
4. When mixing antifreeze and antifreeze, nothing particularly terrible will happen, but still, if possible, do not do this in order to avoid unexpected troubles.

In general, that’s all you need to know about how to replace the coolant on a VAZ 2114. The procedure is not complicated, you just need to do everything carefully and take your time.

From time to time, every driver will have to deal with this operation. It is worth noting that the coolant must be replaced on time, otherwise engine problems cannot be avoided. Do I need to change antifreeze (antifreeze)? How to properly replace coolant. Answer: definitely necessary! The fact is that over time, the coolant loses its cooling properties, heats up quickly, and the engine wears out.

To determine when to change antifreeze or antifreeze, you need to consider the following factors:

Each coolant has its own expiration date:

You also need to pay attention to what mileage your coolant is designed for: the bottles always indicate the lifespan of the coolant: it could be 20 thousand, maybe 40 thousand.

Step-by-step instruction

1. Before starting work, open the tap on the stove in the cabin. This is necessary so that during replacement the liquid comes out of the heater radiator.
2. Place the car on the pit. Next, unscrew the bolts securing the engine protection and casing. Wrench bolts for “10” and “13”. The location of the bolts is in the photo below.

Close the generator with a bottle and place a container to collect the liquid.

Unscrew the drain on the radiator and make sure that the fluid flows into the collection container.

In order for the liquid to come out faster, unscrew the cap of the expansion tank to allow air in.

Unscrew the bolt marked in the photo below to drain the fluid from the cylinder block cooling jackets. Before unscrewing the bolt, place a container for collection. We also recommend that you do not completely unscrew the bolt in order to collect all the liquid as much as possible.

Tighten the drain bolt on the engine block, as well as the plug on the radiator.

• Insert a funnel into the reservoir and fill the coolant to just above the level.
• Place a container to collect fluid under the hose that goes to the throttle assembly. Next, pressing on the hoses in the places marked below, expel the air from the system.

• Place and secure the hose to the throttle assembly. Next, add fluid to the level and start the engine. After warming up the engine to operating temperature, increase the crankshaft speed in jerks to 2-3 thousand (do this for 20-30 seconds). Stop the engine and let it cool. After cooling, add liquid according to the level if necessary.
