Dynamics of demand for second-hand foreign cars speaks about aspiration of future car owners to have the car with the greatest possible quantity of options. One of them is conditioner existence. Even in case the picked-up car according to the main requirements satisfies the motorist, but has no conditioner, the demand for its additional installation though it costs $1,5 thousand often follows.
At the same time, during preselling preparation at the majority of second-hand foreign cars ("Audi 100", "VW Passat GT", "Opel Omega 2,6"), equipped with the conditioner, at control of the engine comes to light inadmissible decrease in a compression in separate cylinders (about 5,5-7,5 atm.). Thus run of some cars of 1994 of release on which at least in one of cylinders there was an inadmissible decrease in a compression, made 50–70 thousand km. As a rule, it occurred in the last cylinder of the engine, the indirect reason of that was its overheat. It is possible to explain it only to that engines in the cars equipped with the conditioner, wear out quicker because of rather high loading created by it at work. The systematic overheat results in premature wear of piston rings.
Fans of "an automobile cool" should remember that the most dangerous to the engine in hot weather is the "idling" mode. In this mode cooling liquid circulates slowly, besides, the radiator of the heat exchanger established under a cowl intensively "warms up" the engine, selecting at it capacity.
Owners of "Audis" equipped with the conditioner, can have the additional problem connected with need of replacement of a belt of a drive of the heat exchanger through each 60 thousand km of run. This in general simple operation can be made only at the removed radiator of the conditioner, according to the subsequent filling by freon that several times will increase working costs. And will undertake it far not in each service.
Undoubtedly, to have the conditioner well, but before it to order, properly weigh all pros and cons.
