Quite often at operation of the second-hand foreign cars just driven from abroad, motorists make mistakes which lead to the most pitiable results. How them to avoid? For example, if in the five years' foreign car driven under the order familiar motorists advise to you to check up levels of all technical liquids and oils and if necessary to add them to norm, – it is not necessary to hurry up. Because during THIS MOMENT OWNERS of JUST BOUGHT FOREIGN CARS SUPPOSE ONE OF the MOST FREQUENT ERRORS WHICH CAN lead to ENGINE BREAKAGE. In particular, many facts of improper maintenance of system of cooling of the motor are known. So, if in the autumn, on the eve of the colds, cooling liquid usually change completely, on spring – only partially. And it is very frequent thus motorists add in cooling system at all those liquids which are recommended for the given model of a foreign car. At the majority of them in system antifreeze is used, and our automobile owners fill in antifreeze or that too happens, – a nonfreezing liquid for a washer of glasses. In what it results? Here to you a concrete example. In repair has arrived BMW at which the engine constantly overheated. By the way, the car has arrived after inspection in two authorised services-centres. There to it some times changed thermostats, a pomp, temperature gauges, but cardinally to correct a situation and it was not possible. It was necessary to suffer fairly while at last, the true cause of defect – a contamination so-called tunnel пароотводящей tubes was found out. And there was it because of mixture of antifreeze to antifreeze, and problems have begun for the second day after it доливки in cooling system.
So, buying in the market or in a motor show a second-hand foreign car, it is not necessary to trust especially to assurances of sellers that the car has had training preselling preparation and a liquid in cooling system it is replaced. Change it independently is better.
In practice quite often there are such situations when engines with considerable – under 300.000 km – run have enough small – no more than 50 % – deterioration. At the same time it is a lot of cars with run to 100 thousand kilometres from which the engine already demands major repairs. Their inspection shows that a principal cause of strong deterioration is the overheat caused by any defects of system of cooling. Not all know that the system of indication of temperature of the engine possesses defined инерционностью. It means that the motor temperature can already exceed an admissible limit, and the arrow of the indicator has not entered yet into red forbidding sector. Therefore we advise: at first signs of movement of an arrow of the device to border of a red zone stop all attempts to reach under the own steam to the house. Know that after the termination of circulation of a liquid in two-three minutes in a block head the steam stopper is formed and avalanche rise in temperature begins. That, in turn, quite often leads to deformation of a head of the block, failure of knots and details газораспределительного the mechanism.
