Replacing the coolant at certain intervals is a mandatory procedure for any car with a carburetor, gasoline or diesel engine. Over time, antifreeze or antifreeze loses its cooling properties, the liquid becomes cloudy, and visual contamination becomes noticeable. Replacing the coolant on the VAZ 2114 and other domestically produced models is carried out strictly according to the instructions, in compliance with the preparation rules, with complete or partial flushing of the system.

Replacing antifreeze and antifreeze on a VAZ 2114

First of all, you need to remember that replacement occurs only in a cooled car, where the engine will be cold. For your own safety, it is prohibited to carry out any actions if the mechanisms are not cooled down.

The eight-valve engine of a vehicle such as the VAZ 2114 has a liquid volume of one and a half liters. Therefore, manufacturers recommend using a volume of no more than eight liters to fill the required barrel with antifreeze or antifreeze.

To completely fill it, two small canisters of five liters each, or one large one containing ten liters of solution, will be enough. The liquid must be mixed according to the instructions included with the specific type of cooler.

Do not forget that if the antifreeze has not been used completely, then you need to add the same type that was used last time. Other manufacturers will not be suitable. It may happen that the model of the previous cooler may be unknown. In this case, special “additional” solvents are sold that will be compatible with other antifreezes (not with antifreeze). It is rated G12.

How to replace antifreeze on a VAZ 2114?

In this way, not only antifreeze is replaced, but also any other liquid that cools the apparatus:

How to replace antifreeze on a VAZ 2114

1. The protection for the engine and other parts consists of four small bolts that must be removed. If there is other protection, you need to get rid of it too.
2. On a cold engine, unscrew the plug from the expansion tank.
3. In the cabin, change the heater indicator to the maximum available indicator.
4. Remove old fluid (as stated above).
5. Unscrew the ignition module, but do not remove it too far.
6. The generator should be covered with something so that small drops of antifreeze do not fall on it.
7. Using a special watering can (or the neck of a plastic bottle), pour in new antifreeze. There is no need to rush, it is better to pour slowly, in a thin stream.

As mentioned above, you should let the car idle for about half an hour until the heater fan turns off automatically. If any failure occurs, you should take the car for repairs or fix the problem yourself.

How to drain

To get started, stock up on all the necessary tools for the job:

• Key;
• screwdriver;
• container for draining;
• new fluid.

If your car has cooled down, then you can proceed to the first part.

1. Place the machine on a level surface.
2. Open the hood.
3. Remove the cap from the tank.

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.

What's in it?

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.

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.

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.

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.

Stage of preparation and flushing of the system

In order for the next coolant you plan to install to function longer and better than the previous one, it is necessary to flush the system in advance. Scale, mucus, traces of oil and various contaminants can remain not only in cars with high mileage, but even in new cars. Therefore, flushing is a must before changing antifreeze or antifreeze.

As a rule, drivers do not use any special rinsing products, but ordinary water, the main thing is that it is clean (preferably distilled, but water from a filter can also work). This is because some chemicals in cleaning products can destroy not only dirt, but also corrode the pipe down to small holes. Only if you are sure that too much residue has formed there and water will not help, then it is better to use a cleaning product.
