How to drain coolant (antifreeze, antifreeze) on a VAZ 2113, 2114, 2115: from the radiator, from the engine

How often do you need to change a VAZ 2114

Like any other liquid, antifreeze does not perform its functions as effectively over time. It becomes dirty, becomes less frost-resistant, and viscosity increases. You can drain the used antifreeze in a VAZ 2114 yourself, saving money on a car service. There are several prerequisites for replacing the coolant:

1. The manufacturer indicates in the technical documentation 50 thousand kilometers; after passing this distance, it is recommended to fill in new fluid.
2. If the car is used infrequently, then you need to drain the old antifreeze when the season changes - early spring or late autumn.
3. If the car uses ordinary water as a coolant, then before the onset of frost it must be replaced with antifreeze.
4. It is recommended to drain old antifreeze, like oil, after purchasing a used car.

Tip: To increase the service life of the coolant and reduce wear on parts, use special additives. They can be purchased at any auto store.

Why does it flow

Before you drain the old fluid and change it, you need to understand why it is leaking from your VAZ 2115. Sometimes it is quite difficult to determine. Try to look through all the pipes, there are several places where the element can leak.

1. Clamps - they may not be clamped well.
2. The pipe itself, which can crack over time.
3. Radiator due to mechanical damage.
4. A pump or pump that wears out over the years in VAZ cars.
5. Leakage from under the head.
6. 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.

How to properly replace antifreeze on a VAZ 2114?

The question of how to replace antifreeze on a VAZ 2114 is resolved in the standard manner. First of all, pay attention to the relevance of these actions. The reason for replacing the coolant may be one of the following factors:

• The service life of the filled antifreeze has expired;
• a leak is detected, the components of the system are repaired or replaced;
• the color of the coolant has changed, foreign impurities have appeared;
• The engine constantly overheats, the antifreeze cannot cope with cooling and gradually boils away.

If during a preventive inspection a low quality coolant is revealed, replacement is carried out with mandatory flushing of the system. It is also relevant if the brand and color of the consumable changes.

When it comes to the frequency of scheduled replacement of antifreeze on the VAZ 2114, they are guided by the service life of the coolant itself. In a car purchased from the manufacturer, it is changed after 60 thousand kilometers . The service life of a replacement consumable is determined by the canister; it is usually 5 years .

When replacing antifreeze on a VAZ 2114, pay attention to certain safety rules :

• all manipulations are carried out with a cooled engine - this avoids thermal burns and high pressure;
• when cooling, the pressure decreases, however, its presence should be taken into account when opening the covers and plugs of the system - splashes and coolant getting on your hands and face are possible;
• antifreeze has a high level of toxicity, it is not allowed to enter the soil; special containers are used to drain coolant and flush water;
• limit the presence of children and animals nearby that can interact with antifreeze.

Taking into account the above factors, the list of tools for replacing antifreeze in the VAZ 2114 includes the following equipment :

• rubber gloves, clean rag;
• a set of keys and screwdrivers, pliers, if possible, a compressor and a pumping bulb;
• drainage container with a volume of 7 liters or more. additional container for rinsing water;
• consumables - new antifreeze, distilled water, optional cleaning agent.

It is also recommended that you first inspect the entire cooling system for worn parts that may soon require replacement. In order not to change the coolant in the near future due to system components, it is recommended to carry out their preventive replacement at the same time as the antifreeze.

All consumables should be purchased only from authorized dealers and trusted suppliers in accordance with the manufacturer’s recommendations for vehicle maintenance. To do this, refer to the technical documentation and identify the original part numbers.

Stage one

Antifreeze is drained from the VAZ 2114 according to the following scheme:

• The car is parked on level ground and, if available, a repair pit or lift is used;
• if the engine has not been running for a long time, it is warmed up for better coolant circulation;
• as additional precautions, remove the minus from the battery, and also cover the generator to prevent antifreeze from getting on it;
• if there is additional engine protection and a protective casing, remove them;
• carefully, taking into account the possible pressure in the system, uncork the radiator and expansion tank caps;
• in the cabin, the heater tap is moved to the right to the maximum to ensure complete drainage of the coolant;
• there is a drain plug in the lower left part of the radiator - place a container under it for draining; before opening it, you should also make sure that the generator is protected from possible ingress of antifreeze;
• to drain the coolant from the cylinder block, you will need to dismantle the ignition module - it is secured with three bolts, the operation does not take much time;
• Place a container under the drain from the cylinder block and unscrew the plug.

Depending on the engine size, about 7 liters of used antifreeze leaks out. To speed up the procedure and ensure complete drainage, some car owners blow out the system with a compressor. Warming up the engine briefly for better circulation also helps. Remains from the expansion tank can be pumped out using a syringe or bulb.

Stage two

To flush the cooling system, use a special product or distilled water. When using the first option, repeated rinsing with water will be required, so many car owners and specialists do not use washing mixtures.

The general washing procedure involves the following stages:

• the lower drains are temporarily tightened, the system is restored to its original form;
• add washing agent or distilled water;
• warm up the engine to operating temperature, turn it off, and allow it to cool;
• drain the rinse in the same way as used antifreeze, repeat the procedure until the water at the outlet remains relatively clean.

Many car owners simplify the cleaning procedure by leaving the bottom drains open and feeding regular water from a hose into the system under medium pressure. This method allows you to avoid constant manipulation of connections and periodic warming up of the engine, but does not guarantee high-quality cleaning of the system.

Stage three

Filling antifreeze for the VAZ 2114 does not have key features that distinguish the process from a similar procedure with other cars. The only nuance is the removal of the coolant supply hose to prevent the formation of air locks.

To replace antifreeze after draining and flushing, the system is returned to its original state and the tightness of the fasteners is checked. After disconnecting the supply hose, new coolant begins to be poured into the radiator. As soon as it flows from the disconnected hose, it is returned to its place.

Next, antifreeze is poured into the expansion tank to the mark indicating the upper limit. Filling is carried out with a thin stream, periodically squeezing the pumping hoses to remove air bubbles.

After filling, screw on the radiator and expansion tank caps, and warm up the engine to operating temperature. The circulation of coolant from the first warm-up will reduce its level in the tank - after the engine has cooled, antifreeze is again added to the maximum.

After 100-200 km, the condition of the coolant should be checked again. Pay attention to the decrease in level - if necessary, add the required amount again and check the system for loose connections and possible leaks. If the color of the new antifreeze has changed, a reddish, brown or black tint has appeared - this is a low-quality product that should be urgently replaced with mandatory flushing of the system.

Replacement

Now we can talk directly about how the coolant is drained and new antifreeze is added.

We noted that 7.8 liters of antifreeze are required to fill the entire volume of the coolant tank. But it is best to purchase a 10 liter canister. This is useful in case you spill some of the liquid past the neck, and also if you need to top up the coolant over time.

If you carry out the work in a clear sequence, watch preliminary training video instructions, then replacing antifreeze or antifreeze will become an easy task for you.

1. Remove the main motor protection. To do this, there are four fasteners under the engine compartment. Although not all cars have protection.
2. Remove the protective cover. It is located in front of the body under the engine.
3. Unscrew the cap from the expansion tank.
4. We climb into the cabin and open the heater tap all the way. This will prevent some of the coolant from remaining inside the system when drained.
5. Prepare a container where all coolant from the system will be drained. A basin or other wide dish is better suited so that nothing spills past.
6. There is a drain plug on the radiator. You will find it on the lower left, in close proximity to the radiator.
7. Don't rush to drain the coolant. First, be sure to protect the generator from antifreeze. To do this, you can wrap it in plastic and put on a bag.
8. Now drain all contents from the radiator.

1. Give yourself access to the drain plug on the cylinder block. To do this, you will have to remove the three bolts securing the ignition module.
2. Place the module aside. Underneath it you will find a plug.
3. Unscrew the plug and drain the old coolant solution.
4. Let the car sit for about 15 minutes. This time should be enough for all the coolant to leave the system. Just remember, the engine must be cold.
5. At this stage, you can flush the system if desired and necessary.
6. After draining and flushing the system, tighten all plugs.
7. Arm yourself with a canister and go to the expansion tank, which is located in the engine compartment. Remove the lid and begin to gradually pour in antifreeze or antifreeze.
8. To avoid spilling the mixture, use a funnel. By inserting it into the fill hole, the coolant update procedure will be much easier.
9. Be guided by the amount of coolant remaining in the canister. In some situations, an air lock may form in the system.
10. To get rid of the plug, compress and release the upper hoses on the radiator.
11. When filling is complete, you should have no more than 2 liters of liquid left in the canister.

Removing the airlock

Useful tips

Finally, we want to share a few very useful tips that will help you avoid mistakes that beginners often make:

• Coolant can only be changed when the engine is cold. If you do this on a hot engine, there is a huge risk of serious burns;
• When adding coolant, make sure that the required amount of mixture is in the system. If it is not enough, there is a high probability of engine overheating;
• Be sure to cover the generator with thick polyethylene or other material so that the solution does not get on it;
• If you mix antifreeze and antifreeze, nothing bad will happen. But try to avoid such situations, so as not to run into problems with the operation of the cooling system.

This is not to say that draining and replacing the coolant is a simple procedure. There are some nuances when updating the contents of the cooling system on a VAZ 2114. But with the right approach, even a car owner without repair experience can cope with this task.

Purpose of antifreeze

There is nothing difficult about completely draining the coolant from the car system. But before starting this process, you need to familiarize yourself with the structure and operating principles of the system as a whole.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

Antifreeze and antifreeze mean non-freezing technical fluid used in the car system not only to cool the engine and other units, regardless of climatic conditions, but also to lubricate certain elements and protect them from corrosive changes. Like all other technical fluids in a car, antifreeze deteriorates over time and loses its properties, which means that this material must be regularly replaced.

According to the rules, it is recommended to change the coolant at least once every three years, however, these dates may shift depending on how intensively the vehicle is used. If you constantly neglect this simple rule, then the recycled liquid will cease to function fully. The consequence of this will be constant overheating of the engine and all adjacent systems, as well as the appearance of corrosion.

Some craftsmen, in order to save money, dilute antifreeze with water, without even suspecting the serious damage they thereby cause to their own car. Thus, adding water causes the pump to jam , which does not receive the required amount of lubricant, as a result of which the belt may break or the gear teeth may be damaged. As a result, the distribution valves and the entire piston system as a whole may fail, so the decision to add water to the antifreeze is clearly wrong, and its consequences can be extremely disastrous.

Step by step draining of coolant

Before you independently begin to drain the coolant from the VAZ-2114, the injector should be understood that this process is carried out in two stages:

• the liquid is drained from the radiator;
• Antifreeze or antifreeze is drained from the car engine.

For this process you will need to prepare the following tools:

• keys size 8, 13 and 17;
• a clean container with a volume of at least 8 liters. The container must be clean so that in the future you can pour coolant back into both the radiator and the engine without loss;
• You will also need to prepare several clean rags.

You can drain antifreeze or antifreeze only after the engine has completely cooled down and certainly until the end.

How to drain antifreeze or antifreeze from the engine?

Now you need to move the container under the engine block, there is a drain plug on it, you will need to unscrew it.

But first you will have to remove the ignition module along with the bracket on which it is attached, so the plug is located under it.

We wait until everything drains, after which we wrap all the parts back so that we don’t forget about them later. Now you know how to drain the coolant, but another question arises. Does the system need to be flushed?

If the car is not old, then you don’t have to wash it, it depends on the condition, but they are mostly washed with distilled water; if it is a more neglected option, then you can buy special washes specifically for these purposes. Then fill in new antifreeze or antifreeze.

Quite a lot of car enthusiasts prefer to independently maintain their passenger vehicles and monitor their technical condition. In order for your faithful four-wheeled friend to work properly and not let the driver down on the road, various repair or preventative operations have to be periodically carried out, including replacing the coolant.

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.

How to drain the coolant and flush the engine cooling system on a VAZ 2114

It is far from a fact that when buying a used car you will be able to find out literally everything about the car you are purchasing. For example, do you know what kind of coolant is used? Some people use antifreeze, others prefer antifreeze. Although there are some unique car owners who use ordinary water.

When buying a car secondhand, be sure to check the presence and quality of coolant in the engine system.

So, you purchased a car and don’t know what exactly is in the cooling system. If there is water or already used coolant there, this does not bode well for your engine.

Therefore, first of all, check whether there is any coolant in the engine at all, and what exactly it is. At the same time, make sure there are no leaks from the pipes or radiator.

It is not difficult to independently determine the type of fluid used by the old owner.

Mixing different coolants. Yes or no?

In some cases, the quality of the fluid is good enough that it is not necessary to replace it. Only the quantity is somewhat below the required level.

Let's say you have antifreeze filled, but you only have antifreeze on hand. What to do in such a situation? Many VAZ 2114 owners are interested in whether it is possible to mix different compounds.

Antifreeze or antifreeze

There is no consensus on this matter. Let us say for sure that a disaster will not occur from mixing, antifreeze and antifreeze will not react and will not explode the car. But we definitely cannot recommend combining two types of coolant in one tank. Follow the instructions in your car's manual, fill in what the factory recommends, and then you won't have any problems.

Antifreeze is simply a type of antifreeze developed in Soviet times for Zhiguli cars. This was done due to the low quality of the antifreeze offered at that time. Since then, antifreeze is the number one choice for VAZ.
