Most manufacturers change the traditional gaskets of the lubricant motor vehicle with polymer compositions that quickly freeze. Such sealants are sold in liquid state and they solidify under specific conditions that depend on a certain chemical formula of the substance.

It is not so easy to choose a sealant for a lubricant motor system, as the vehicle owner should pay attention to several important factors that include the temperature resistance and the chemical composition of this agent.

In addition, it is desirable to choose only high-quality sealants - professionals advise the products of well-known and common trademarks that are most popular and tested by time.

Car sealants (adhesives) are also called liquid gaskets, and they appeared on the market relatively recently. However, in a fairly short time, managed to prove their importance, utility and necessity in the most difficult situations.

Sealants replace strips

The most important function of sealant is the ability to replace the engine gasket or other necessary details; eliminate the leakage of oil, antifreeze or other liquid; Bonding some elements or prolque bus. There are several types of automotive sealants - silicone, anaerobic and heat-resistant.

Today there are a lot of items of sealants of a variety of manufacturers. They are distinguished by the level of elasticity and resistance, color, temperature range and other characteristics. You can also allocate professional sealants and for ordinary drivers. Sealants for professional use are presented in large volumes and they are significantly more expensive.

Import funds are sold in plastic or aluminum tubes with a cap-dispenser, which have a lot of forty or ninety grams. Domestic sealants are presented as an aluminum tube with a plastic cap. Undoubtedly, the composition with a tube dispenser to apply and store is much more convenient. In this case, the sealant does not dry out and is suitable for reuse. Remains from the dispenser can be easily removed using ordinary matches.

Some professional sealants require a special pistol, since it cannot be applied without it. Select remedy is very careful. It is not recommended to save on the packaging, since large tubes are cheaper, but there is a possibility that the substance dries either the end of its storage. If you want to apply the sealant in both the gasket, it is necessary to check its heat resistance. Ideal heat resistance - 345-375 degrees Celsius. It is not necessary to carry a product with you every day, but on long-distance trips without it difficult to do.

Apply the sealants not only for the automotive engine, but for a variety of parts and vehicle systems. The scope of use is rather wide - body parts, sealing and mounting hatches, glasses, units connectors. The cooling system also needs a special means. In addition, there are sealants with a narrower specialization: threaded compounds, jamming of punctures in tires, pipeline connecting parts, planting hose, flange surface. Materials of sealants have a significant difference in their properties, on this when choosing a sealant, you must clearly know what it is necessary for you.

Silicone sealant, dignity and disadvantages

To repair the motor, the most common among drivers is the silicone classic sealant of the oil system, which is very convenient to use. The natural components of this substance take a solid state during contact with moisture, which is constantly in the air.

To accumulate the desired volume of fluid, it is necessary about ten minutes - this time will be enough to fasten the elements. But in some cases it is desirable to hurry. For example, if you install the pallet of the motor or other large elements, since the silicone sealant can be frozen before combining the two components of the node. In such a situation, you need to remove the residues of the substance before the second attempt to build.

Silicone car sealant for motor repair has several advantages over other types of compositions:

1. Maximum thickness of the cavity, which is filled with sealant, reaches six millimeters.

2. The resulting seam is quite elastic and retains its properties for a long time.

3. Silicone sealant is able to operate with very high pressure, which is important for high-sword powerful motors.

For this reason, silicone compounds use most motorists - make a mistake while working with them is quite difficult. As for minuses, when using silicone sealants, it is necessary to thoroughly clean the connected planes and plan all the actions before the start of work.

Anaerobic sealant, dignity and disadvantages

Anaerobic motors for the motor are a good alternative - such funds appeared quite recently, but they were greatly popular in the professional sphere. If the presence of water is needed to frost silicone sealants, then for anaerobic - no oxygen.

To apply this tool, it is necessary to apply it to the element and strongly press it to the surface of another part. Be the most careful as possible, since if the oxygen access is maintained, the sealant will remain in liquid form.

The main advantage of the anaerobic sealant for the motor pallet is the possibility of its unhurried application to the connected surfaces - while these items will not be pressed to each other tightly, the frost is not made. Undoubtedly, the effectiveness and quality of sprouting sealant is able to affect and foreign impurities, in particular dust and water. This is desirable to apply anaerobic sealant not very slowly. In addition, this composition is very elastic after solidification, which is capable of ensuring reliability and durability of the connection. However, anaerobic sealants have a number of flaws:

1.Maximum thickness of the sealant of space is not exceeded 0.5 millimeters.

2. During operation in conditions of high pressure, the composition may collapse.

3. If anaerobic sealant is uneven, its part will remain in a liquid state.

This is how to work with anaerobic sealant without relevant experience undesirable, it is better to trust it with specialists.

Heat-resistant sealants, dignity and disadvantages

Also, it is necessary to pay attention to the temperature tolerances of the substance you are going to apply - they depend on the chemical composition, but are not determined by the presence of esters in it or silicone. To collect a vehicle motor, it is advisable to buy special heat-resistant sealants that can withstand a temperature of 345-375 degrees Celsius.

If you apply a sealant when working with other elements of the vehicle, which are located in the subcontrol space, the temperature tolerance in two hundred degrees will be enough. For all other purposes, you are suitable for sealants that are capable of collapsed at a temperature of 150-170 degrees Celsius.

Professional sealants Loctite and Goetze, reviews, advantages and disadvantages

If you are interested in which sealant is better for the car's motor, look at the instruction manual for the vehicle, since it can always find recommendations from the manufacturer. Professionals recommend buying branded sealants, on the packaging of which the logo of a particular automotive company is applied.

You can buy such sealants in special automata, service centers or using online directories. Undoubtedly, such funds will cost much more than their analogues, however, you will receive a guarantee of the tightness of the oil system and the strength of the assembled engine.

A good universal option for machines from any manufacturers are professional sealants of the manufacturer Goetze and Loctite (Lokatet). Such sealants are frozen about ten or twenty minutes, and during the accidental launch of the motor and the engine heating, almost in all cases retain their properties, as well as, do not allow the oil system.

The durability of such funds has been proven many times in practice - the motor is able to work without signs of leaking oil for two hundred thousand kilometers. A minus such sealants can be called their high price.

Erling and Reinz Sealants, Dignity and Disadvantages

Reinz and Erling are no less high-quality and effective means for the motor crankcase pallet - they are practically not inferior to the above-described means of strength and durability of the formed compound. But what would make the composition of frozen much more time, professionals advise to wait about an hour.

The tests carried out testify that such sealants are able to maintain their properties for 150-200 thousand kilometers depending on the operating conditions of the vehicle. The advantage of the above-described funds is also the optimal price.

Hi-Gear and Abro sealants, dignity and disadvantages

ABRO and Hi-Gear can be attributed to the third division of automotive sealants that are designed to build a motor, tire repair.

They are effective and inexpensive. They have no special deficiencies or advantages - sealants freezing pretty quickly and medium in the field of reliability and durability. To attach elements of high-breasted motors with large loads, they are not recommended to be applied.

Protection against fakes, deposit of successful repair

In the field of automotive sealants for motors, it is advisable to navigate the price - usually, how it is higher, the tool is better. Although it is often possible to meet fakes that do not allow you to get a fairly durable connection. It should be recognized by the absence of branded holograms, codes and other control elements provided by manufacturers.
