3.2. General information about settings and adjustments
"Settings" in the present manual are meant as not separately taken procedure of correction of the car, any of parameters of systems, and the whole complex of the adjustments allowing to achieve maximum efficiency of return of the engine.
If the owner of the new car from the date of its acquisition strictly adhered to the Schedule of routine maintenance (see the Section Schedule of Routine Maintenance), rather often carried out checks of critical parameters, supported the required level of lubricant liquids, the engine will need extremely seldom performance of additional service and recovery repair (over replacement subject to the increased wear of components and expendables).
On the other hand, in case of the negligent relation to performing procedures of regular maintenance and frequent violation of established periods of conducting checks, efficiency of return of the engine will surely decrease sooner or later. The probability of emergence of such situation in case of acquisition of the car which was in the use is especially high. In such cases there is a need for performance of a complex of settings of the power unit over amount of works on routine maintenance of the car.
The first step at control or diagnostics of malfunctions working with the lowered return of the engine always is check of compression pressure in cylinders (see the Head Dvigatel) which analysis of results allows to estimate the general condition of internal components of the power unit and to draw up the plan of the forthcoming adjusting and/or recovery work. For example, if check of compression pressure revealed signs of serious internal wear of the engine, there will be not enough usual complex of settings for correction of a situation, and its carrying out will be waste of time and means. In view of the value of information obtained as a result of check of compression pressure, its performance should be charged to rather skilled and qualified mechanic having necessary diagnostic units.
Lists of the main adjusting procedures allowing to achieve maximum efficiency of return from the engine which is in a working mechanical order are given below.
- During each filling check the level of motive oil, brake fluid, cooling liquid and liquid of a washer of glasses;
- At least, than once a month check pressure of a rating of tires and level of cooling liquid of the engine in its broad tank;
- It is desirable, time during a season (for example, every spring and fall) check the level of GUR and ATF liquid.
