Air conditioner: not only "pluses", but also "minuses"
The dynamics of the demand for used cars shows the desire of the future car owners to have a car with the maximum possible number of options. One of them is the presence of the air conditioner. Even if you pick up the car for the motorist satisfy the essential requirements but does not have air conditioning, often follows its application for additional installation, though it costs $ 1.5 thousand. However, during the pre-sale preparation at the majority of used cars ("Audi 100", "VW Passat GT", "Opel Omega 2,6"), equipped with air conditioning, under the control of the engine revealed an unacceptable reduction in the compression of individual cylinders (about 5, 5-7.5 atm.). At the same time run some cars 1994 release in which at least one of the cylinders had an unacceptable reduction in compression, it is 50-70 thousand. Km. As a rule, this happened in the last cylinder of the engine, which was the indirect cause of overheating. This can be explained only by the fact that the engines in vehicles equipped with air conditioning, wear out more quickly due to the relatively high load created by them at work. Systematic overheating leads to premature wear of the piston rings. Fans of "cool car" should be remembered that the most dangerous for the engine in hot weather mode is "idle." In this mode, the coolant is circulated slowly, moreover, mounted under the hood of a radiator exchanger intensively "heats" engine, taking his power. The owners of the "Audi", with air conditioning, it may be an additional problem with the need to replace the heat exchanger drive belt every 60 thousand. Km. This is generally a simple operation can be performed only when the air conditioner to remove a radiator, respectively, followed by refilling freon, which increase the cost of the work. And take on this is not in every service. Sure, have a good air conditioning, but before his order, carefully weigh all the "pros" and "cons".
