THE GENERAL DATA

Dynamics of demand for second-hand foreign cars speaks about aspiration of the future automobile owners to have the car with the greatest possible quantity of options. One of them is conditioner presence. Even in the event that the picked up car under the basic requirements satisfies the motorist, but has no conditioner, the demand for its additional installation though it manages in $1,5 thousand frequently 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 the engine control inadmissible decrease in a compression in separate cylinders (nearby 5,5–7,5 атм comes to light.). 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 in km. As a rule, it occurred in 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 faster because of enough high loading created by it at work. The regular overheat leads to premature deterioration 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 the cooling liquid circulates slowly, except that, the radiator of the heat exchanger established under a cowl intensively "warms up" the engine, selecting at it capacity.

Owners "Audi", equipped with the conditioner, can have the additional problem connected with necessity of replacement of a belt of a drive of the heat exchanger through each 60 thousand of km of run. This in general can be made simple operation only at the removed radiator of the conditioner, according to the subsequent refuelling by freon that several times will increase working costs. And undertake it far not in each service.

Undoubtedly, to have the conditioner well, but before it to order, properly weigh all pro's and con's.
