How to choose and replace antifreeze on a VAZ 2107: instructions and photos

The engine cooling system is an important part of every car, through which the normal operation of the engine is ensured. A significant part of the cooling system is devoted to refrigerant or coolant, which can be presented in the form of antifreeze (in most cases), antifreeze or distilled water.

During the operation of any car, including the VAZ 2107, it is important to promptly replace the coolant, which will improve the efficiency of the cooling system. In this issue, we will look in more detail at how to correctly replace antifreeze on a VAZ 2107, what is required for this and where to start.

Instructions for replacing antifreeze

Antifreeze, compared to water, is quite resistant to frost - it does not freeze. It is also not a source of scale, which means it does not clog the cooling system.

But, subjected to constant temperature influences and fluctuations, antifreeze loses its properties during operation:

the boiling point decreases and accordingly becomes equal to the boiling point of water;
The fluid may freeze, resulting in a cracked reservoir or cracked cylinder block.

For these reasons, it is necessary to change antifreeze at least once every six months. It is important to do this during seasonal car maintenance. Timely replacement of coolant will help avoid unpleasant consequences, unwanted repairs and unnecessary waste of money.

So, replacing antifreeze on a VAZ 2107 includes draining the antifreeze, flushing the cooling system (if necessary) and replacing the used coolant with new antifreeze or antifreeze.

You should first prepare the following materials and tools:

canister with new antifreeze (6 liters);
funnel;
wrench “13”;
open-end wrench “16”;
key “12”;
an empty container of 6-10 liters (a cut canister is often used);
a clean rag made from natural fabrics;
Protect your hands with gloves.

Drain

Draining antifreeze from the VAZ 2107 tank includes the following sequence of actions:

Place the car on the inspection hole so that the front wheels of the car are higher than the rear ones;
Move the lever (located on the dashboard) that supplies warm air into the cabin as far as possible to the right;
Open the hood and unscrew the expansion tank cap;
Unscrew the central radiator cap;
Using a 16mm open-end wrench, unscrew the drain plug located on the cylinder block. Place a container prepared in advance, as liquid will begin to pour out. It may take up to 10 minutes to completely drain the spent fluid;
Using a “12” wrench, unscrew the plug on the radiator drain hole, located in its lower part. A special bucket or container is used for draining;
Remove the belt holding the expansion tank by hand. You should raise the tank as high as possible, thus draining the remaining antifreeze from the hose connected to the tank;
After completing the procedure for draining antifreeze or antifreeze, the tank is installed in place, all drain holes are then closed and the cooling system must be flushed.

Flushing

Flushing the cooling system is an important procedure. It determines how effectively the VAZ 2107 engine will be cooled. A number of car owners believe that flushing the cooling system is a waste of time, and immediately fill in new antifreeze or antifreeze after draining the used fluid. This causes clean and dirty fluid to mix, negatively affecting performance.

You can flush the cooling system using either water or special products.

HOW TO DRAIN THE COOLANT CORRECTLY

Somehow, unnoticed, the time has come when it is necessary to replace the coolant on a VAZ 2114. You do not need to have a higher education in order to replace the antifreeze on a VAZ 2114. Even novice drivers can do it. Let's try to take a closer look at the question of how to drain the coolant. To do this, you need to stock up on empty containers for drained antifreeze, and prepare some tools.

Wrenches for “8”, “13” and “17”;
Screwdriver Set;
Rags;

It will be useful: Tuning a Niva pickup with your own hands: suspension, engine, body

It is best to drain the coolant from a “warm” engine and always with the interior heater radiator valve open. The further procedure for draining antifreeze from a VAZ 2114 will be as follows:

Remove the engine protection so that the coolant can be completely drained;
Remove the cap on the expansion tank;
Place an empty container under the radiator and open the drain plug. It is necessary to ensure that the drained liquid does not flood the generator set. The draining process can take about 15 minutes. After draining is completed, wipe the plug with a rag and put it in place;
The next step is to drain the coolant from the engine. Move the container under the engine drain plug and open it. It is found under the ignition module, which is best removed while draining the coolant. The process also lasts approximately 15 minutes. The cork is wiped with a rag and screwed into place. This completes the draining process.

Features of antifreeze and antifreeze

Let's start with the fact that Tosol is a type of antifreeze developed in the USSR. But as often happens with us, the name has become a household word and many liquids for car cooling systems are called Antifreeze.

Antifreeze and antifreeze are based on ethylene glycol (less commonly propylene glycol), distilled water and various additives. And the main difference between them comes down to the additive package.

Antifreeze is made from equal parts of water and ethylene glycol using traditional technology, which includes additives based on salts of inorganic acids.

But antifreeze already includes carboxylate additives (from salts of organic acids).

Thanks to additives, these liquids have anti-cavitation, anti-foam and anti-corrosion properties.

But the traditional manufacturing technology that is used in the production of Antifreeze is already somewhat outdated due to additives. Additives made from salts of inorganic acids cease to perform their functions over time. Antifreeze has a longer additive life.

At the same time, the additives themselves work differently . The anti-corrosion additive in Antifreeze covers all metal elements of the system with a thin protective layer. But this same layer makes it difficult to remove heat.

In antifreeze, this layer is much thinner than that of Antifreeze, and at the same time it covers only those elements of the system that are susceptible to corrosion.

If you look at it in general, then in a debate - antifreeze or antifreeze for VAZ, in terms of its performance properties, antifreeze wins. But not everything is so simple and a lot depends on the VAZ model itself.

The fact is that most domestic cars are primarily designed to work with Antifreeze. It is the main liquid, although the operating instructions often indicate that antifreeze can also be used.

How to prepare a car for draining coolant

To drain the antifreeze, you need to perform some preparatory measures. Since the substance in question is toxic, it should not be dumped on the ground. For these purposes, resealable containers are used, which are disposed of in accordance with environmental standards. Preparing the car consists of placing it on a flat horizontal surface to more effectively drain fluid from all pipes and components. On almost all cars, the coolant is drained through a special hole, which is sometimes located in the lower part of the radiator or on the pipes.

If there is no hole, drainage is carried out through the removed radiator pipe.

If there is no drain hole, the coolant is drained through the radiator pipe

An important point is compliance with safety precautions: draining antifreeze from a hot engine is strictly prohibited. Due to the high heating temperature of antifreeze, there is a high probability of getting burns during operation. In addition, as a result of heating, the liquid in the system is under pressure and when any lid is opened, it will be released. Therefore, you first need to wait until the engine cools down to ambient temperature and only then unscrew the cap of the expansion tank and radiator.

Why does it flow

There are many options for why coolant may leak. It is very difficult to determine this location of the leak. The main ones are:

View all pipes; perhaps one of the clamps is not clamped properly.
The pipe itself has cracked from time to time.
The cause of mechanical damage is in the radiator. This can be corrected by welding or gluing. You can determine the location of the leak in the radiator using dismantling or gel sealant.
Water pump. Over time, the pump, like any other part, can wear out and leak. In this case, the pump will have to be replaced.
The element leaks out from under the head. It is better to correct such a leak at a service center, since this will require disassembling the engine.
When the element leaks directly into the vehicle's cabin. This can be determined by lifting the floor mat on the driver or passenger side.

Important! You can replace antifreeze on a VAZ 2114 only with a completely cooled engine. Antifreeze is toxic, as a result, when handling it it is necessary to adhere to the strictest safety precautions and prevent it from coming into contact with the skin. Before turning on the engine, you need to tighten the cap of the expansion tank tightly.

How to drain

Before starting work or before draining the cooler, you must place the car on a level surface. If this is not possible, then raise the front part slightly higher than the back.
Next, disconnect the wire from the negative terminal of the battery.
The heater lever must be moved all the way to the right.

How to fill

To avoid an air lock, the clamp must be loosened. The hose that supplies coolant from the heating fitting of the throttle assembly must be disconnected.

How to replace antifreeze on a VAZ 2107

Now it's time to fill in new antifreeze. To do this, open the radiator cap and insert a funnel there. Remove the plug from the cylinder block and ask your partner to pour in antifreeze in small portions. At this time, tighten the bolt, and as soon as antifreeze flows out of the BC, immediately tighten the bolt. This is necessary to prevent the creation of air jams. Then pour antifreeze into the radiator until it is completely filled. Next, without screwing the cap on the radiator, pour antifreeze into the expansion tank until it reaches the radiator. After this, screw on the tank cap.

Cooling system elements

The process of draining coolant from the radiator

In order to understand how and why it is necessary to drain the coolant, you need to have a little understanding of the design of the car and the cooling elements. Also, you need to know how the coolant circulates in the engine and have an idea of the places where it can be drained.

So, let's look at the complete diagram of the engine cooling system and how the coolant circulates:

Coolant drain options

There are two options for draining coolant from the system. They depend on what operations the motorist intends to perform with the car. So, let's look at both options separately.

Draining without removing the engine

This method is often used to replace coolant in the system, as well as to change cooling elements. The procedure is quite simple. Let's look at how to properly drain the liquid from the cooling system completely:

We find the cooling system plug on the cylinder block.

Unscrew the plug on the radiator to drain the coolant

Installation of faucet

For the convenience of subsequent draining and repair work, you can install a faucet. Moreover, you have already unscrewed the standard plug.

Draining with engine removal

The second method is easier than the first and is used when the engine is planned to be removed. Let's consider the sequence of actions aimed at draining coolant from the system:

Unscrew the plug on the expansion tank.
We unscrew the plugs from the cylinder block and radiator.
Next, when the liquid has flowed out, you need to unscrew the pipes leading to the radiator.
Of course, some liquid remains in the system and must be drained completely. This can be done in two ways: by blowing it out with a compressor or by disassembling the engine.

Why do you need to drain the coolant?

This “slurry” has already served its term

Let's look at the main reasons why you will need to completely drain the coolant from the system:

Development of a full resource of use . It is recommended to carry out once every 90-100 thousand km. This is due to the fact that the coolant, due to a constant temperature difference, which is its operating temperature, loses its technical and physicochemical properties. After such a mileage, it can no longer effectively provide cooling of the engine and its elements, which can lead not only to failure of the thermostat and pump (most often these are the spare parts that suffer), but also to boiling of the engine, which can have unpleasant and material consequences .
During engine overhaul . When the engine is dismantled for major repairs, the coolant will need to be completely drained.
Replacing the radiator will also require draining the coolant completely from the system, but it is done according to a simplified option (the second one, which is indicated above).
Replacement of other individual elements that will require draining the coolant from the system.

Replacing the coolant: why is this event being carried out?

The cooling system of modern cars is presented in the form of a liquid-type system, which means heat is removed from the car engine through liquid. The coolant circulates through the system, removing heat from the engine and cooling in the radiator. The pump or water pump redirects the cooled portion of the liquid to the engine to cool the latter again. The heat exchange process occurs continuously while the car engine is running and the pump is rotating.

We recommend: Inflating tires with nitrogen - real benefits or a marketing ploy?

As the coolant is constantly exposed to different temperatures, it loses its properties over time. When antifreeze loses its properties, its boiling point decreases and approaches the boiling point of ordinary water. Most often this happens after a mileage not exceeding 60 thousand km. It is at this mileage that it is recommended to completely replace the antifreeze in order to avoid unforeseen and undesirable consequences. Before we begin the replacement, let’s find out how to properly drain antifreeze from a VAZ 2107.

How to properly drain used fluid

To drain antifreeze from a VAZ 2107 car, simply opening the tap is not enough, through which all the liquid will flow out of the system. Both antifreeze and antifreeze are toxic substances, so when working with them you should follow safety rules. Before draining, it is necessary to prepare a container into which the waste will be drained. The volume of such a container should not be less than 10 liters. The best option for such purposes is a trough or basin.

It is easy to carry out the work without an inspection hole, so it is recommended to install the car on the handbrake, and then place a trough or other container under the engine. We begin the process of draining the liquid, for which the following steps are performed:

The first step is to open the hood, then unscrew the cap from the expansion tank. This is necessary in order to reduce the pressure in the system, thereby speeding up the process of draining the waste. It is also recommended to unscrew the cap on the radiator.
It is necessary to open the heater tap from inside (move the lever to the “warm” position) in order for the coolant to drain from the heater radiator.
The next step requires unscrewing the plug bolt, which is located at the bottom of the cylinder block.
Now you can start unscrewing the drain plug. located on the radiator. After unscrewing it, drain all the used fluid into a container, which may take up to 10 minutes.
At the next stage, you need to loosen the fastening of the expansion tank, and then lift the latter up to drain the remaining liquid from it. How much antifreeze will be in the system depends on how often the car owner added it there.

The capacity of the cooling system of VAZ-2107 cars is just over 8.5 liters, so you need to wait until the last drop flows out. While the antifreeze is draining, you can prepare a new canister that will be poured into the system.

It is important to know! It is strictly forbidden to start the car when there is no antifreeze in the system.

Features of filling coolant

During the process of replacing the coolant, you can perform the procedure of changing the sealant or clamps on the pipes if leaks were noticed earlier. To do this, it is necessary to remove the pipes, check their integrity, remove any old sealant, then apply a new one and put it back in place. If the pipes have obvious defects, then it is better to replace them immediately, so that after a while the new antifreeze does not end up under the car.

Before adding a new type of antifreeze, you should tighten the drain bolt on the cylinder block, as well as the lower plug on the radiator. Remember to complete these steps before you begin the pouring process. We recommend doing the filling as follows:

Before filling, unscrew the sensor located between the spark plugs of the 3rd and 4th cylinders, slightly higher, from the cylinder block. This will prevent the formation of an air lock in the car's cooling system;
now antifreeze is poured into the VAZ 2107 through the hole in the radiator until it flows out of the hole from the sensor in the block in an amount of about 5 liters;
screw the sensor into place and continue pouring;
It is necessary to pour until the radiator is completely filled. You can additionally move the pipes to release air from them;
After filling the radiator, you need to close its cap and add coolant into the expansion tank to the range from “MIN” to “MAX”.

It is important to know! Replace the coolant on your car only when the engine is cool. Antifreeze is very toxic, so inhaling its vapors can affect your well-being.

On VAZ 2107 cars, the injector and carburetor differences in the cooling system are insignificant. The only difference is that the temperature control system sensor is installed on the injector and the throttle body is heated. The carburetor engine of the "seven" has a more simplified cooling system, but they work on the same principle. There is no difference in the coolant capacity of the cooling systems of carburetor and injection engines. Above is a video about how antifreeze is replaced on a “seven”.

How to properly drain antifreeze from the cooling system of a VAZ 2114

During engine operation, almost all of its parts are exposed to high temperatures. To cool them in a car, including the VAZ 2114, a special liquid (antifreeze) is used. It circulates through the system and is cooled in the radiator by oncoming air. Used antifreeze must be periodically drained from the tubes and new one filled in.

Timing for replacing coolant in VAZ 2107

The purpose of the coolant in the VAZ 2107 is to remove excess heat from the car’s engine. Indeed, during operation, many parts of an internal combustion engine reach temperatures of 300 degrees C. If the engine is not cooled in time and sufficiently, it will fail. Coolant solves this problem; it is supplied to a running engine, flows through the channels, thus taking away excess heat from the internal combustion engine.

After heating, the coolant goes into the central radiator, which is constantly blown by the fan. After cooling in this unit, the liquid returns to the engine cooling channels. This is the procedure for continuous liquid cooling of the VAZ 2107 engine.

The general principle of operation of the VAZ 2107 cooling system can be studied using the diagram below.

How to understand what kind of coolant is required for a VAZ 2107 - antifreeze or antifreeze? Since we are talking about Russian cars, we should distinguish between concepts such as antifreeze and antifreeze to clarify concepts.

It should be noted that such division and differentiation is accepted only in the Russian Federation. To answer this question, you must first understand: what is coolant?

We recommend: How to properly store tires

So, the basis of the coolant is ethylene glycol, less often propylene glycol. Special additives are added to it, which protect against corrosion. Each manufacturer adds different types of additives.

Let us differentiate the coolants available on the modern market according to additive production technologies:

traditional, in which additives are made from salts of inorganic acids: silicates, nitrites, amines, phosphates;
carboxylate, additives are made from organic carbonates;
hybrid, consists of a mixture of organic carbonate additives and inorganic salts (in smaller quantities, including phosphates or silicates).

So, the main difference between antifreeze and antifreeze is that coolant made using traditional technology is called antifreeze, while coolant made using carboxylate technology is called antifreeze.

Advantages and disadvantages of using antifreeze

Pros:

protective film. Thanks to the inorganic salts contained in antifreeze, a protective film is created on the surface of the cooled parts, protecting them from corrosion. The film reaches 0.5 mm. In the picture below you can see how antifreeze creates a protective layer, the disadvantage is that it interferes with heat removal;
color change. If the driver forgot to change the coolant, a clue to the need for the procedure will be the color of the liquid, which is easy to notice just by looking into the car's expansion tank. The changes are that as the antifreeze loses its useful properties it becomes darker, and completely unusable antifreeze cannot be distinguished from tar;
affordable prices. Coolant produced using traditional technology is 3 times cheaper than antifreeze.

Disadvantages of antifreeze:

replacement frequency. Antifreeze has a short lifespan, becoming unusable after 50 thousand kilometers;
negative impact on aluminum parts. The additives used to create antifreeze negatively affect the aluminum surfaces in the main radiator (which significantly reduces its service life);
due to the tendency to form condensation, it negatively affects the water pump of the VAZ 2107, as a result - premature wear of its impeller.

Let's look at the advantages and disadvantages of using antifreeze

Pros:

service life is longer - 6 liters of antifreeze is enough for 150 thousand kilometers;
temperature selectivity - due to the presence of carbonate additives, antifreeze more actively protects the engine surface that is heated the most;
antifreeze does not interfere with heat dissipation, and also protects corrosion areas with the help of local layers;
long engine operation due to temperature selectivity and timely engine cooling with antifreeze;
there is no condensation, which means antifreeze cannot damage the radiator and water pump of the VAZ 2107.

The disadvantage of antifreeze is obvious - its high cost. In terms of price, it is on average 3 times higher than antifreeze.

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:

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

Replacing fluid on a VAZ-2107

Carrying out all the work on this car is not that difficult. Tools you will need:

Key to 13;
Key for 30 (possibly);
Screwdriver;
Drain container;

You should also take care of purchasing new fluid. In this car, its quantity in the system should be 8.65 liters.

The work is carried out in the following order:

The car is placed on the platform and time is given to cool down (if the engine is warm);
Remove the caps from the radiator filler neck and expansion tank. Also in the cabin, on the heater control panel, we move the lever to heating, thereby opening the heater radiator tap;
Unscrew the drain plug at the bottom of the radiator. On older models there is no such plug, so on them the temperature sensor is unscrewed with a 30 key. There is also a drain plug on the engine, which we also remove. We collect the leaking liquid into a prepared container;
After draining, install all plugs in place;
We wash the system. To do this, distilled water or a special detergent is poured into it. In order to completely fill the system and displace the air, remove the pipe going to the intake manifold. As soon as water or liquid comes out of it, we put it in place;
We start the engine so that it flushes the system through circulation;
Drain the water through the plugs. Fill in new coolant. We start the motor for circulation. Then we are interested in the amount of liquid in the system and, if necessary, add it to the expansion tank to the required level.

How to properly drain antifreeze from the system

If your VAZ 2114 is about to replace the antifreeze, it is not necessary to take the car to a service center. Having prepared several tools, you can do everything alone without the help of craftsmen. If there is an old coolant container left in the garage, it is perfect for draining waste material. The tools we need are:

Wrenches for 8, 13 and 17.
Flathead and Phillips screwdrivers.
Cleaning rag.

Its viscosity depends on the temperature of the liquid. Therefore, in order for the antifreeze to drain better, work must begin with a warm engine. In the VAZ 2114 cooling system, hot antifreeze is also used to heat the interior. When draining, be sure to unscrew the heater radiator valve.

Step-by-step instruction

The work consists of the following stages:

First of all, open the hood and remove the engine block protection.
Remove the cap from the expansion tank.

Remove the cap from the coolant reservoir VAZ 2114

Open the plug at the bottom of the radiator and begin to drain the liquid

Open the plug on the engine and drain the antifreeze

The draining process is quite simple and will take you no more than an hour. After finishing the work, it will be useful to wipe the nearby parts from dirt.

Draining antifreeze (coolant) from the radiator and engine block on video

Coolant replacement should be carried out regularly twice a year or after 50 thousand km. The procedure does not take much time and does not require large financial costs. If you delay this, the cooling system will not be able to fully perform its function.

Coolant functions

Maintaining normal temperature during engine operation (injector).
Maintaining low temperature in the gearbox (hydraulic fluid that needs to be poured into the automatic transmission).
Interior heating in winter. Pouring antifreeze provides heat to the car by passing through the heater. The motor heats the liquid, and the fan blows air and transfers heat. Thus, heated air enters the cabin.

Antifreeze in the VAZ 2107 should be replaced every 45,000 km. or once every two years, whichever comes first. Because over time the quality deteriorates and this leads to adverse consequences.

Radiator cap open

Replacement frequency

The manufacturer prescribes three conditions for replacing the fluid (depending on what comes first):

The coolant is replaced every 80-100 thousand kilometers.
The fluid needs to be changed every 4-5 years, regardless of mileage.
If the color of the fluid turns brown, then it needs to be replaced urgently. When the fluid loses color, its chemical composition changes, and it has a detrimental effect on the cylinder head and other parts in the cooling system made of aluminum.

HOW TO FILL CORRECTLY WITH COOLANT

Before properly filling the coolant, it is advisable to flush the system. To do this, pour distilled water into the system and run the engine for about 10 minutes. After this, the water is drained and its condition is assessed. If it is cloudy, the process must be repeated several times.

Filling with coolant

Now let's talk about how to properly pour antifreeze into the cooling system. If you don’t know how much antifreeze is in the VAZ 2114 cooling system, then let us remind you that 7.8 liters of antifreeze or antifreeze are needed. The filling process is carried out in reverse order.

When pouring coolant into the cooling system, air pockets inevitably occur. To get rid of them, do the following:

Disconnect the hose on the throttle pipe;
Wait for coolant to appear from this pipe and put the hose in place.

Start the engine and warm it up to operating temperature. If no leaks are found, check the coolant level in the expansion tank. It should be between the min and max marks. This will complete the work of replacing the coolant.

Which is better: antifreeze or antifreeze?

Antifreeze is a general name for all coolants that remove excess heat from engine parts.

Antifreeze is the name of a domestic coolant that has become a household name for Russian consumers.

This means that antifreeze is antifreeze, only from a certain manufacturer.

However, there are quite a lot of differences between domestic material and other antifreezes.

Antifreeze comes in several colors: red, yellow and blue. Antifreeze, as a rule, has no tint or is produced blue.

The colors of materials are not regulated by any documents, so this division is arbitrary.

As a general rule, blue antifreeze is a material based on inorganic compounds - silicates, phosphates, nitrites. It forms a thick protective layer that prevents corrosion. However, this film impairs heat exchange and can cause engine overheating. Antifreeze is also made on the basis of inorganic components.

Red coolants contain organic materials that do not form a thick film and do not interfere with heat transfer. However, they do not provide anti-corrosion protection; the materials create a thin layer at the sites of corrosion to prevent their growth.

Green compositions include inorganic and organic components, therefore they are a middle link between the above materials.

For the cooling system of the Lada 2115, the preferred choice is Antifreeze, as it was developed specifically for cars manufactured by AvtoVAZ. Although imported fluids will work no worse there, it is only important to take into account the compatibility of a particular coolant with the power unit.

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.
