Thus, the filler Glas, with glass, is characterized by high mechanical strength, and therefore it is recommended to fill deeper irregularities. The length of the fibers in it are not very big – about 1-1.5 cm vymeshivat This allows her as well as all other types of fillers, namely – chopping motions, trying to squeeze out the air mass. Putty is very durable, so you can patch up even small pockets of rust. However, at large surfaces where the metal 'plays' (for example, the roof of the car) use this type of filler is not worth it, because it is completely inelastic. Optimal use of space – pillar sills, arches and other details of the bottom of the car. Alu – Putty with particles of aluminum – a fairly universal product.
Because of its very fine structure (perhaps one of the most fine-grained coatings), can fill even very minor scratches. The risk Education chipped in places of transition from fine-finish surface to neshpaklevannoy minimal. At the same time, is characterized by high mechanical strength. Especially recommended for work on horizontal surfaces, subjected to temperature effects (such as hood of the car) due to high content of aluminum, it has a coefficient of thermal expansion close to the same value of the metal. This allows prevent cracking and peeling in places puttying. Putty least prone to shrinkage: filling in the form of aluminum powder is unable to saturate a large amount of solvent. The lightweight filler Leicht 30% lighter than conventional fillers.
The cooling system of a modern car consists of several main elements: the cooling jacket of the cylinder, which is a cavity in the walls around the combustion chambers, radiator, expansion tank, pump; Thermostat fan located in front of the radiator; thermode; connecting pipes (hoses) Antifreeze. The function of the cooling system – to maintain optimum engine temperature under various conditions. It achieved as follows. The circulation of coolant in the system is ensured by a liquid pump, and can occur in small or large circle. Small circle includes the cooling jacket of the cylinder, thermostat and pump. On this path, bypassing the radiator circulates antifreeze after a cold start to the set operating temperature. Low, released by the combustion of gasoline, antifreeze is absorbed in the moment of passing them shirts cooling of the cylinder. By keeping its own heat engine warms up faster.
They are not visible and usually becomes audible, when it is too late – it is a wheel bearing. We give you the information to a certain state of the art, as well as some practical advice on diagnosis and wheel bearing grease car. As a general rule, professionals in the field of Autoservice recall wheel bearing, when a client complains about the noise of the wheels. But we must not forget that car wheel bearing subject to extreme stress: high temperature extremes, and various environmental influences (not least in salt), and, as a result of the perception of attacks by roughness of the road, drive, brakes and steering – different dynamic loads. Given these circumstances hub bearings should be inspected regularly. It is necessary to pay attention to the fact that wheel should rotate without backlash, with acceptable noise, and minimal friction. In passenger cars, two types of wheel bearing.
Pour point, driven generally in the technical characteristics of the oil is obtained through laboratory tests and is the temperature at which the oil is almost completely loses its fluidity (mobility). In fact, the performance of engine oil is lost much earlier, even at much lower temperatures than when it has already lost the ability to be pumped regular system of engine lubrication. Thus, the selection of oils for use in the winter must be guided not by freezing point and viscosity class SAE. – For all brands of whether vehicles can use motor oil viscosity grades 5W-… and OW-…
