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.
When the optimum temperature is reached, the thermostat responds to it. The main valve thermostat opens and the liquid conducted in a large circle. The elements of the small circle is now added to the radiator and the sensor. In the radiator is the heat transfer between a liquid and air. Then the cooled fluid continues to move to the water pump. If the temperature rises too much, triggered sensor, connecting to the process fan.
Fan pumps air through the core of the radiator increases the intensity of this heat transfer. Depending on the mode of the engine coolant temperature is constantly changing and therefore change and its volume. The resulting surplus of antifreeze out of overflow tank, and excess vapor pressure discharged through the valve reservoir tank cover. Upon cooling, the reverse is true, and the tank gets air from the atmosphere. Through the expansion tank and pouring antifreeze poizvoditsya system. Each element of the system plays an important role. a 'knockout' of at least one of the links in the chain, if not immediately resolve the problem, can lead to system failure or entirely in the best case, or the engine to overheat, with all consequences.

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-…
Replaced in the bottom of the piano, the newspaper spread out on rice. This time the rice is no longer wet, a little damp newspaper of the deca-futor. I pray to God that he sent me the strength to finish the job. By evening the engineer the piano and, leaving, ask the next day to rest as much ustal.Den eighth (29aprelya). Rest. Before dinner, sleep and eat a lot.
