History of coolants (antifreeze)

The first engines of the 19th century were air-cooled.

Around 1900, water-cooled engines appeared.

Since the 1930s, pumps and thermostats have been used for the first time to increase cooling efficiency.

Early coolants or antifreezes were: 1. Saline solutions of sodium and calcium chlorides. 2. Solutions of glycerin, sugar and honey. 3. Methyl and ethyl alcohols.

Since 1930, ethylene glycol has been used for the first time.

Since 1939, special anti-corrosion packages have been used.

Why is a car engine cooling system necessary?

Combustion of the fuel mixture in the engine occurs at temperatures of 2100–2300°C. At this temperature, without forced cooling, engine parts would heat up to a temperature significantly higher than the ignition temperature of the oil. In addition to oil combustion, when the engine overheats, the frictional forces and wear of parts increase, thermal clearances decrease, oil coking and carbon deposits occur, and the filling of the cylinders of carburetor engines with the combustible mixture, and of diesel engines with purified air, worsens.

At the same time, excessive heat removal leads to engine overcooling and a change in the viscosity properties of the oil, which leads to increased wear of parts, a decrease in engine power and efficiency. The ideal thermal regime of the engine is 85-95°C, regardless of its load and ambient temperature.

Honest liters or tricky kilograms?

Don’t think about it, we’re not talking about being slandered in the markets.
We are talking about already packaged goods. About the usual antifreeze in original packaging. Meet the new word for us - DOWNSIZING. Downsizing in marketing is reducing the quantity of a product in a package without changing the price. Literally translated from English, “Downsizing” means reducing size.

Downsizing can be carried out both in terms of reducing the weight (volume) of the package and in terms of reducing the physical size of the product packaging without changing the price of the product.

The purpose of downsizing is to increase or maintain the profitability of selling a unit of goods by reducing the cost of the product, by reducing its volume (weight) in the product package, while maintaining the same cost per unit of goods.

Downsizing task:

– in one case, downsizing is a not entirely honest practice of obtaining benefits from the manufacturer, based on the inattention and addiction of consumers to the product;

– in another case, downsizing is a forced price incentive measure that allows you to maintain positions in the price segment, while increasing the cost of goods on the shelf and maintaining the required rate of profitability.

– in the third, downsizing is a tactic of following the leader (following the trend in the price segment), when a direct competitor and leader applies this tactic, forcing other competitors to use it, especially if we talk about price segments from the middle and lower.

Not a liter anymore...

We are accustomed to the fact that coolant packaging is strictly a liter. And how could it be otherwise, everything seems to remain the same. But often we simply do not notice the obvious. For example: the density of antifreeze with a freezing temperature of 40 ºС should be 1.075 g/cm3. i.e. 1 kg of antifreeze will be 1/1.075 = 0.93 liters.

Let's figure it out. Let's start first by determining the actual weight. Often, when purchasing antifreeze, you see on the label not 5 liters, but 5 kg. So how much product will we buy in liters? So: 1 liter of antifreeze in terms of kg is equal to 1.075 kg. Accordingly, by purchasing 5 liters of coolant, the output is 5.375 kg. On the other hand, by purchasing 5 kg of antifreeze, we get an output of 4,675 liters. Here is the answer - 325 ml went into the manufacturer’s pocket.

Considering that, on average, for many cars the volume of coolant is over 5 liters, it will be difficult for the buyer to notice that he is a victim of downsizing.

This tactic is “on the verge of deception,” but carried out within the framework of the law, since formally you can’t find fault: the weight or volume is always indicated on the packaging and nothing prevents the buyer from determining and understanding for himself the profitability of purchasing a particular product that has undergone downsizing. Downsizing is a form of camouflage for increasing product prices.

In the medium + and higher price segments, downsizing tactics are used just as actively, but the “honest packaging” marketing strategy is increasingly gaining popularity among product manufacturers, allowing it to attract the attention of buyers.

We, AzotKhimFortis, officially declare - our liters are HONEST!

How to dilute antifreeze concentrate?

All information is on the label. If information is missing or unclear, remember the following:

• Never pour concentrate pure without dilution. You will receive antifreeze with a freezing point of -13°C and a strong corrosive effect.

• It is not recommended to use antifreeze with an ethylene glycol content of more than 67% and less than 30%. Common dilution: 33% ethylene glycol and 67% water (1:2) will give you -17°C. 50% ethylene glycol and 50% water (1:1) will give you -36°C. 55% ethylene glycol and 45% water (1 ,2:0.8) will provide –40°C. 65% ethylene glycol and 35% water (2:1) will provide –65°C.

Replacing antifreeze on a VAZ 2107

Antifreeze replacement in domestic VAZ 2107 cars is carried out at standard intervals - once every 2 years or after 60,000 km. It all depends on which condition is met first. In addition, the fluid must be replaced if it has changed color, for example, acquired a reddish tint.

Which antifreeze is better, and how much should I fill it with?

Before draining the antifreeze, you must decide on the brand of new coolant and purchase it in the required volume. VAZ 2107 cars require 9.85 liters to fully refill the cooling system. This means that one 10-liter container of antifreeze will be enough. When purchasing coolant, please note that some antifreezes are sold in the form of concentrates and require dilution with distillate in a 1 to 1 ratio.

To replace antifreeze, you can use the following types:

• For “sevens” from 1998 to 2002, the optimal coolant option is G12 red. This includes MOTUL Ultra, Lukoil Ultra, Castrol SF and others.
• In VAZ 2107, manufactured from 2003 to 2012 and beyond, it is recommended to use G12+ or G12++ antifreeze of the following brands - MOTUL Ultra, Castrol Radicool Si, Zerex G.

Replacement process

Before draining the antifreeze, stock up on the necessary tools. You will need a minimum set, which includes a key for “thirteen”, a group of screwdrivers, a container (this is where the old coolant will be drained), as well as 10 liters of the new composition in a canister.

Replacing antifreeze begins with draining the old working fluid. To begin, find a flat surface to perform all manipulations. It is better to work on an overpass or pit, in a garage. If it is not possible to park the car level, the front part can be raised slightly higher than the rear (the reverse situation is excluded).

Then proceed like this:

1. If present, remove the engine protection. To do this, just unscrew the twelve fastening bolts. Also remember that there are four plastic fasteners.
2. Go to the salon and move the lever to the right, which is responsible for the release of warm air from the heating system in the car's interior. As a rule, it is located on top.
3. Open the expansion tank. Assess the condition of its plug and, if there are defects, replace it.
4. Open the filler neck at the top of the car's radiator.
5. Unscrew the plug that closes the coolant outlet from the engine cylinder block. Before draining the antifreeze, place an empty container (bucket or bottle) to remove the old coolant.
6. Move the container or place a new container under the radiator, then open its drain. Wait until the old coolant is completely out of the system.
7. Discard the belt that holds the expansion tank. Now lift the tank up to drain the antifreeze from the connected tube. The remaining coolant, in this case, exits through the drain in the radiator.
8. Leave the car for a while to ensure that the coolant has completely drained out.

Filling with new antifreeze

Now proceed to replacing the antifreeze. To do this, proceed like this:

• Return the cooling system reservoir to its original place and screw the plug onto the drain hole of the VAZ 2107 cylinder block. Do the same with the drain plug on the radiator - screw it into place.
• Pour new antifreeze into the radiator, and then do the same work for the expansion tank. Monitor the position of the coolant in the system using the control marks. Stop pouring antifreeze when the line is 3-4 cm above the MIN line.

Removing air from the system

Now remove any air pockets from the system. To do this, find the outlet, bypass and supply pipes of the radiator, and then press them several times with your hands.

You can do it differently. Park the car so that the front is higher, start the engine and let it run for 5-6 minutes at idle. Now return the radiator and reservoir caps to their original places. After starting the engine for the first time, check the coolant level in the tank again. If it is not enough, top up.

Finally, consider the following points:

• Replacing antifreeze should be done exclusively on a cold engine.
• Remember about the toxicity of coolant, so work should only be done outside. All manipulations can be performed indoors, provided there is good ventilation.
• Three days after the replacement, check the antifreeze level again. If necessary, bring it to normal.

At what temperature do antifreeze and antifreeze boil?

Antifreeze is essentially a type of antifreeze and appeared on the market decades ago along with the appearance of the first VAZ cars. At that time he had excellent characteristics. Each coolant differs from other liquids in the presence of a certain type of additives designed to protect engine elements from corrosion and wear. The additives contained in antifreeze are best suited for VAZ engines. Antifreeze is of the best quality and is intended for engines of imported cars.

To distinguish between types of coolant, dyes are added to them. Usually the colors are red, blue or green. Thanks to this, and the fact that the expansion tanks are made of translucent plastic, the driver can quickly and accurately determine whether there is enough coolant in the system. When the coolant loses its original color, it indicates that it is time to replace it. Next, I will talk about in what situations antifreeze can boil.

The freezing point of antifreeze and antifreeze is the same (depending on the coolant concentration), and the boiling point of antifreeze is slightly different from the boiling point of antifreeze. For antifreeze the boiling point is 110 °C, and for antifreeze it is slightly higher - 120 °C. The temperature difference is small, but in the hot summer it can be significant.

The above values ​​for the boiling point of antifreeze and antifreeze are correct for a fully functional engine cooling system. If there are foreign impurities in the antifreeze or antifreeze or the expansion tank cap has lost its tightness, the boiling point may be lower.

ATTENTION!

Ethylene glycol is a strong poison. If ingested, it causes severe intoxication, damaging the central nervous system and kidneys. The lethal dose for an adult is 100 ml. The problem is the sweet taste, which can attract your children and pets. We do not have statistics on ethylene glycol poisoning for Russia, but in the USA, where this problem is taken under separate control, over a thousand cases of fatal poisoning are reported annually. Avoid contact of ethylene glycol with skin. We strongly recommend that you store antifreeze, like all technical fluids, out of reach. Spilled antifreeze should be immediately removed with a rag or sand and then disposed of. Getting ethylene glycol into soil or water also poses a threat to plants and fish.

To ensure environmental safety and eliminate cases of poisoning, propylene glycol-based antifreezes are used. Propylene glycol has long been used in the production of food, medicines and perfumes. In heating systems for residential premises and food production, according to European standards, only propylene glycol is allowed to be used. Most municipal transport in Europe has switched to propylene glycol. Propylene glycol, unlike ethylene glycol, is less aggressive to metals and has greater thermal conductivity.

How to convert one measure of quantity to another?

How to convert liters to kg? This way of asking the question is incorrect, since it is possible to convert from one quantity to another if they belong to the same physical category. Example: you can easily convert hours to seconds (a measure of time), but it will be difficult to do this for milliliters and grams (a measure of weight and volume).

Two conditions must be met in order to still transfer a substance from one system of quantities to another:

1. Determine the specific gravity of the substance.
2. Choose a substance that would connect the selected categories of weight and volume.

How many liters are in the system?

Well, now the most interesting thing is how much antifreeze is needed. I will provide a breakdown of several popular brands and models:

VAZ. In older versions (2101 - 2107) it was about 8.6 liters . Fresh front-wheel drive versions (PRIORA, KALINA, GRANT 2109 - 2115) - 7.8 liters

RENAULT. In particular LOGAN (SANDERO) – 5.5 – 6 l.

KIA ( Hyundai) . In particular, let's talk about RIO (Solaris). It all depends on the engine size: 1.4 – 5.5 liters; 1.6 – 5.8l

Daewoo . In particular NEXIA. Engine 1.5 (8 valves) – 6.2 liters, 1.5-1.6 (16 valves) – 6.7 liters.

If we take the arithmetic average for various brands and brands, engines with a volume of 1.4-1.6, it turns out from 5.5 to 8 liters . In any case, you need to buy two 5 liter canisters. There will still be left for topping up (and you’ll also flush the system a little)

BUT this is what interested me, and I think you will too. Why exactly so much antifreeze or antifreeze, that is, say 7 liters, and not 3 or 10 liters? Why such a volume? And there is a completely reasonable explanation for this.

Why change antifreeze at all?

The thing is that antifreeze or antifreeze itself (this is a Russian, or rather a Soviet invention) becomes unusable over time, and if you don’t want your radiators, pipes or hoses to corrode, you must change them!

What and how does it corrode? Just a few words for understanding - look, coolant consists of three main components:

Well, actually, why do you need to change? YES, just after 3 - 5 years the additives wear out and stop working, that is, the liquid that is poured inside becomes VERY active.
