General information on control

GENERAL INFORMATION

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 of components subject to raised wear 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 subsection compression Check in engine cylinders) will help to define a condition of internal components 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 (subsection Check of a condition of tires and pressure in them)
· Check of a condition of all hoses of an impellent compartment (subsection Check of a condition and replacement of hoses of an impellent compartment, localization of leaks)
· Check and adjustment of a tension of driving belts (subsection Check of a condition of driving ridge belts)
· Cleaning, survey and check of a charge of the battery (subsection Check of a condition of the battery, care of it and charging)
· Replacement of spark plugs or incandescence ( subsection Check and replacement of spark plugs)
· Survey of VV of wires of candles, except models with direct ignition
· Check of the air filter (subsection Replacement of a filtering element of the air filter)
· Check of system of cooling (subsection Check of functioning of system of cooling)

General settings

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

· Check of system of ignition or preheat
· Check of system of a charge
· Check of fuel system
· Replacement of VV of wires of spark plugs, except models with direct ignition

The cover of a jellied mouth of oil is located in a cover of a head of cylinders – each time before opening it, be convinced that a surface round a mouth the pure

Level of oil should remain between two labels, it is desirable at level or is close from top them them – if it not so, add oils to the top label. The amount of oil between marks of MIN and the MOVE makes 1 l. Two options of execution of the index of level of oil are shown

The broad tank (the cooler tank) is located in a lateral part of an impellent compartment. Liquid level on the cold engine should be between MIN and MAX labels. On the hot engine some excess of level of a mark of MAX is possible. If necessary uncover and add a cooler
