Sealant for engine cooling system: reviews and recommendations

Even in the most reliable cars there are annoying breakages. They are minor, but they can give drivers some inconvenience. So, cooling systems often flow . The causes of leaks are temperature differences, which contribute to the development of heat fatigue in pipes with thin walls. As a result, microcracks appear in the pipeline, from which the cooling liquid then escapes. Solve the problem by simply replacing the tired and current parts, but not always the necessary detail can be found on sale. If the leakage occurred on the way, then the sealant for the engine cooling system will help . How to solve the problem using these tools, consider in the article.

History of sealant

When these funds did not exist, the problem of leaky radiators and cooling systems was already acute for motorists. It was necessary to look for simple methods that could help, if necessary, to pressurize the system urgently.

So, used to dry dry mustard. When added to the coolant, the powder formulation can very quickly reduce or even completely eliminate cooling fluid leaks. But after using this "medicine" it was necessary to launder everything. After all, the powder hammered not only the microcracks, but also all the cavities of the cooling system. Today they do not use mustard. But then with the help of it drivers drove from 300 to 500 km. This recipe really helped to survive the drivers of the Soviet army in Afghanistan.

The modern chemical industry is constantly evolving and has already mastered the production of a variety of products that allow you to quickly eliminate any leaks and get to the SRT. There are many types of these funds. Drivers are often interested in what the best sealant for the cooling system is. Reviews are also of interest to car owners. Reviews - it's much better than any advertising. They show how effective this or that tool is in reality.

Tasks of sealants

These funds are not a panacea and can not eliminate leaks forever. Any substance also makes the cooling system work worse, therefore it is recommended to use such chemistry only in the most extreme and extreme case, when it is very far to go to the nearest SRT.

Deterioration of channels in the radiator

The use of sealants significantly reduces the efficiency of the radiator. So, the channels are hammered. In modern radiators are installed textolite or plastic spirals, which are designed to improve the heat transfer from the coolant to the surface of the radiator. The sealing agent settles on the surface of these spirals, thereby significantly reducing not only the capacity of the channels as a whole, but also the vortex effect. That's why those who used sealant for the engine cooling system, feedback, advice give that this is not a means for prevention. This is an effective way to prevent leakage in an emergency. After using the product it will be necessary to thoroughly rinse the entire system and replace the damaged parts.

Types of sealants for the cooling system

There are two types of these funds. It:

• Powder formulations;
• Means based on polymer.

Powder means work the same way as mustard. The cooling liquid is absorbed into the powder, it swells from this and clings to the edge of the crack. At this point a blockage is formed, which stops the leakage of liquid. Powder sealant is very effective at small diameters of cracks. Thus, the diameter of the hole should not exceed 1.5 mm. If the crack is larger, then using these tools will not do anything.

The polymer compositions harden when contacted with oxygen. After the composition was poured into the system, it is mixed with the cooling mixture. Then, along with the OZ, the composition gets to the place of leakage, and under the influence of oxygen the process of solidification begins. These tools are effective, but only if the diameter of the hole is not more than 1 mm.

The advantages and disadvantages of sealants

The advantages are obvious: it is an opportunity to get to the nearest service station and save the motor from overheating. After all, it is not always possible to call the tow truck. But the effectiveness of this autochemistry is manifested only on small leaks. It is important to choose a good sealant for the engine cooling system, reviews of those who have already used these tools will help in choosing.

The reviews say the following. The disadvantages of these compounds are that they only allow you to get to the repair site and eliminate only small defects. Also after use, the entire system should be thoroughly rinsed, but it is much easier than replacing the cylinder head and doing overhaul after overheating.

The mileage of a car with a sealant should not be more than 100 km. After all, these substances significantly worsen the operation of the cooling system. Significantly deteriorating the flow of the cooling mixture through the radiator, also significantly reduces the efficiency of heat recovery, increases the temperature of the engine.

Fillinn

This is a domestic product, but made to order Pride USA. The agent is a white polymer emulsion. The composition is very easily shaken and begins to function immediately as soon as it enters the tank.

During the tests to seal the holes in the steel tube, he could not cope with the largest hole in 1 mm, and all of these holes four. This is 0.3 mm, 0.5 mm, 0.8 mm and 1 mm. However, the remaining holes were not clogged up so quickly. Also, the remedy leaves behind many deposits. The price of this composition is democratic, but with serious damages it will not help. He took the last, sixth place in the ranking. On this sealant for the engine cooling system, the responses of the owners are neutral. Nothing good can be said about him. But as an inexpensive structure that will help get to the SRT, it will do.

Gunk Radiator Sealer Super

This tool is manufactured in the USA. Its price is from 160 rubles. This is a thick brown mixture. It works quickly and efficiently. The product could close all the holes and practically simultaneously. However, too much sediment. This can be very dangerous if the radiator is old enough and dirty. Together with this product, you need to know how to flush the sealant for the engine cooling system.

You can say the product is even effective. The speed of work is also at a good level. But among the minuses is a large amount of residual contaminants. But this, again, is a budget option for an emergency situation.

Hi-Gear Stop Leak

There is also a producer here - the USA. The product is a fibrous substance of a blue-green color. After the composition was carefully mixed, his work seemed rather strange. The leak ceased and appeared again. The first test holes were clogged only when all the liquid was completely drained from the cooling tank. The product even clogged the drain hole.

Verdict - high efficiency, because the plugs are formed even in the holes are large enough. Work composition - a slow, spasmodic. The deposition level is also high. Price - from 190 rubles, which is also very budget.

K-Seal

These products are also designed and manufactured in the USA. The price of the bottle is 430 rubles. It is a thick brown emulsion. In the composition there is a special copper powder, thanks to which durable plugs are formed. The work of the drug is effective. However, at large holes, the speed decreases. But there are practically no residual deposits. It is also a quality sealant for the engine cooling system. Reviews about him - only positive.

Liqui Moly

These are German metal-containing sealants. After draining the liquid, the sediment will play with all the colors of the rainbow. This is a true leader among all products in terms of speed, and the leaks ceased and did not reappear again. At a price of 200 rubles the level of deposits is less than average.

BBF "Super"

It is a domestic sealant for the engine cooling system. BBF reviews are generally positive. The product is a white emulsion. This composition works very efficiently and according to the classical mixture. The holes are closed from the smallest to the largest. There is practically no sediment. The composition is created on a polymer basis, and the plugs in the holes are small and neat. At the same time, the estimated price of this composition is only 50 rubles. Despite the low cost, the product showed the best results among all.

Than to wash out hermetic for system of cooling of the engine

After using these compounds it is recommended to thoroughly wash the cooling system. But this can not be done with simple water. Here it is necessary to use special means.

Purifier from Liqui Moly

This preparation is designed to remove from the SOD a variety of contaminants, including residues of sealant, which prevents the correct operation of the system. The product does not contain any corrosive substances. It can be used in most systems. They can easily wash off any sealant for the engine cooling system. Reviews - cylinder head after this cleaner remains without deposits.

Lavr - for complex contaminants

This is a two-component formulation that helps to clean even heavily clogged cooling systems. It cleans all the cavities of the system from scale, destroys other contaminants. The drug contributes to the removal of various contaminants from the system.

The product is created on an alkaline basis and can dissolve fatty contamination and other products. Also, the agent neutralizes the effects of acidic agents, and washing with this drug is completely safe.

There are other manufacturers on the market that offer similar products. But you need to know clearly which product is qualitative. From what sealant for the engine cooling system (the reviews help to assess the strengths and weaknesses), the quality of the cooling system and the car as a whole depends.
