General information on control

The term "control" is used in this Management rather for designation of a complex of procedures, than one separate procedure.
If from the moment of car purchase the schedule of routine maintenance is strictly observed, frequent checks of level of liquids and a condition subject to the increased wear a component as it is offered in this Management will be carried out, the engine will long remain in a good working condition, and need for carrying out any additional work will be minimized.

Is more often, however, happens so that the engine works inefficiently owing to neglect with regular service. Even more often it happens upon purchase of the second-hand car which owners did not trouble themselves with frequent and regular checks and service. In this case, besides performance of usual procedures on routine maintenance, it will be necessary to make setup of the engine.

The first step in any procedure of control or diagnostics for the purpose of improvement of operation of the engine is check of extent of compression in cylinders. Compression check (address to Head the Engine) will help to define a condition internal a component of the engine and should serve as the index at carrying out control and repair. If, for example, check of extent of compression indicates serious internal wear of the engine, usual control will not help to improve its work and will be waste of time and money. As procedure of check of extent of compression is the extremely important, the expert owning the equipment specially intended for this purpose should see off her.

For engine reduction in a good working condition performance of the following procedures more often is required.

Minimum settings

· Check of all liquids connected with operation of the engine (The section Check of levels of liquids, control of leaks).
· Check of a condition of all hoses of an impellent compartment (Section Check of a condition and replacement of hoses of an impellent compartment, localization of leaks).
· Check and adjustment of a tension of driving belts (Section Check of a condition of ridge belts of a streaming drive of auxiliary units and Head Engine).
· Cleaning, survey and check of a charging of the battery (Section Check of a condition of the battery, care of it and charging).
· Replacement of spark plugs or an incandescence - on the diesel engine (Head engine Electric equipment).
· Check of the air filter (Section Replacement of an element of the filter of air of salon / coal filter of purification of air).
· Check of system of cooling (The section Check of levels of liquids, control of leaks and Check of functioning of system of cooling and frost resistance of cooling liquid. Liquid replacement).

General settings

All points of the minimum control listed above, plus...
