Solvents
Solvents for cleaning carburetor and throttle body parts
Solvents of this type are aggressive towards rubber and carbon deposits, as well as towards films formed as a result of oxidation and polymerization of fuel and oil. After treatment with this type of solvent, a dry film usually forms on the surface of the parts, which does not harden completely and, at the same time, repels resins dissolved in the fuel. Due to film formation, such solvents are not suitable for cleaning electrical system components.
Solvents for cleaning brake system components
This type of solvent is used to remove dust from brake system components caused by wear of friction linings, traces of grease and spilled brake fluid. When servicing and repairing the brake system, it is necessary to ensure that its elements are as clean as possible. After treatment with such solvents, no film remains on the surfaces of the parts, and the specific squeal of the brakes caused by contamination of their parts often disappears.
Solvents for cleaning electrical system parts
These solvents remove corrosion and carbon deposits from electrical contacts, ensuring reliable flow of electrical current. Solvents for treating electrical system components can also be used to clean spark plug contacts, carburetor jet holes, voltage regulator contacts and other parts on whose surfaces a film should not form.
Means for absorbing condensation and moisture
These products are used to treat the surfaces of generator parts, voltage regulators, electrical connectors and fuse boxes. These products also have anti-corrosion and insulating properties.
Degreasing agents
These products are powerful solvents that are used to remove lubricants from engine casing surfaces and chassis components. Degreasers are applied to the surface with a brush or from an aerosol can and are removed by rinsing with water or another solvent.
Lubricants
Motor oil
Used in the engine lubrication system. Motor oil often contains additives and supplements that have a beneficial effect on the wear resistance of engine parts and reduce the degree of corrosion on them. The degree of oil viscosity fluctuates within the range of 50 values. The viscosity of the oil recommended for use depends on specific climatic conditions and technical requirements. Less viscous oil is added to the system in cold weather and low engine loads. Oil with higher viscosity is used in warm weather and high engine loads. Synthetic oil can have both high and low viscosity grades in the range from 5W-20 to 20W-50 and can be used in all weather conditions and vehicle operating modes.
Transmission oil
It is used for lubricating differential and manual transmission parts, as well as units operating in high-temperature conditions.
Lubricant for chassis elements and wheel hub parts
It is a plastic lubricant that has the ability to retain its properties under conditions of high friction and increased load. It is used for lubricating wheel hub bearings, ball joints, steering rod ends and CV joints.
High temperature grease for wheel hub bearings
The grease is intended for lubricating wheel hub bearings with disc brakes. Bearings are subject to temperature changes that accompany the operation of the disc brake. Typically, these lubricants are developed on the basis of molybdenum disulfide.
Cannon fat
It is a plastic lubricant used to protect metal connections located in areas of high humidity. Technical lard retains its plasticity over a wide range of temperatures and has water-repellent properties.
Assembly motor oil
High pressure molybdenum based grease for parts operating under heavy load conditions (for example, main and connecting rod bearing journals, as well as valve lifters) when starting the engine for the first time after a major overhaul. Assembly motor oil is held on surfaces and lubricates them until the motor oil from the engine lubrication system begins to flow.
Silicone lubricants
It is used to protect parts made of rubber, plastic, vinyl, and also containing elements made of nylon. Graphite lubricants
The use of graphite lubricants eliminates the increased susceptibility to contamination of parts, as when using other types of lubricants that have an oily nature (used, for example, for lubricating lock parts). Graphite particles are distributed over the surfaces of metal parts and do not attract dust, while having the properties of repelling various liquids, including aggressive ones, and resisting the effects of corrosion. Being a good conductor, graphite-based grease will not contaminate electrical contacts, such as ignition switch contacts.
Molybdenum-based lubricants with increased penetrating ability
They are used to separate and lubricate parts that have frozen or are unable to separate due to combined corrosion, as well as to subsequently protect elements from the effects of cold and corrosion.
High temperature grease
It is an electrical insulator and is used when installing ignition system coils for thermal insulation purposes.
Sealing compounds
RTV brand sealants
One of the popular sealants. Made from silicone, RTV has the properties of sealing, insulating, compacting, repelling water and leveling surfaces. At the same time, the sealant does not lose its plasticity and elasticity, can be easily removed from the surface, and can be used to seal joints in combination with almost all automotive gaskets operating in low and medium temperature conditions.
Anaerobic sealant
Similar to RTV in that it can be used both in combination with the main gasket and directly as it. It also does not lose its plasticity, the ability to adhere to surfaces and fill their unevenness. The main difference between the two types of sealants is the different curing conditions. RTV cures when exposed to air, while anaerobic sealant can only cure when there is no air available. Thus, the anaerobic sealant hardens only after the elements are assembled, bonding them together.
Sealant for threaded and pipe connections
The product is used for sealing hydraulic, pneumatic and vacuum pipelines. As a rule, the product contains Teflon.
The sealant is supplied in aerosols or tubes.
Chemicals
Anti-seize compound
It is used to prevent the bonding of parts surfaces and to protect the mating surface from corrosion. This high temperature product is typically a copper and graphite based lubricant and is used to treat the threads of exhaust manifold mounting bolts and exhaust system components.
Anaerobic compositions for fastening parts
They are used for sealing and fixing connections. The sealant hardens after the fastening parts have been installed, when air access to the surfaces treated with the compound is blocked. The compound with medium bonding strength is used to treat small threaded parts that have to be unscrewed during regular maintenance procedures. Large diameter nuts, bolts and studs that are not removed regularly are treated with a high-strength adhesive.
Motor oil additives
They have a range of purposes, from increasing oil viscosity to reducing friction between the surfaces of engine parts. It should be noted that most manufacturers do not recommend using additives to their brand of motor oils.
Fuel additives
They differ functionally depending on their chemical composition. Typically, fuel additives contain solvents to clean the surfaces of carburetor parts, fuel system components and the intake system. The combustion chamber surfaces are also cleaned of carbon deposits. Some additives contain lubricants for the top surfaces of the cylinders, valves and piston rings, while others contain substances that absorb condensation from the fuel tank.
Other means
Brake fluid
Specially designed for use in brake hydraulic systems under high pressure and temperature conditions. Avoid contact of brake fluid with paintwork on metal and plastic parts. Keep the container with the liquid tightly closed to prevent contamination or water ingress.
Adhesive for seals
It is used to secure rubber seals on doors, windows and the trunk lid. Sometimes glue is used to bond cladding parts together.
Anti-corrosion treatment for the underbody
This product is made from petroleum and resembles tar. It is designed to protect the metal surfaces of the car's underbody from corrosion. Treating the bottom with this compound also improves noise insulation.
Wax coatings and polishes
They are used to protect paint and galvanic coatings from harmful climatic influences. The possibility of using these products sometimes depends on the type of paint or galvanic coating. Some polishes remove the top, dull layer of paint using an abrasive or chemical solvent, which is especially important when servicing a used car. Recently, many silicone and other polymer-based polishes have appeared that do not contain wax. These products make polishing easier and provide a more durable effect.
