Repair and operation of the car

The owners of cars performing procedures of routine maintenance of the car it agrees the present manual of the schedule provided in Chapter 1 will be extremely seldom forced to address materials of this Section. Reliability of the knots and components installed on modern cars is so high that at timely performance of replacement of the details which are worn out and failed as a result of aging of material the probability of their sudden refusal is extremely small. Refusals seldom happen spontaneously and usually are a consequence sometimes of long development of defect. In particular, the refusal of mechanical components practically is always preceded by emergence and development of the characteristic symptoms which are shown sometimes for many thousands of kilometers of a run to an exit of defective knot out of operation. The same components which can fail unexpectedly usually are not vital for functioning of the main knots and systems of the car, or are easily replaced directly on the car in road conditions.

Fundamental step at identification of the reason of any refusal is the choice of a point of the beginning of searches. Often the reason is rather obvious, however in certain cases it is necessary to work, making small investigation. The motorist who produced half-dozens of casual checks of replacements and corrections quite has chance to find a cause of failure (or its symptom), however such approach cannot be considered reasonable, in view of its labor input and aimlessness of expenses of time and means in any way. There is a quiet logical approach to search of the failed knot or component much more effectively. Surely it is necessary to take into account everything the insignificant symptoms and the guarding signals preceding breakage, sometimes, such as loss of the power developed by the engine, change of indications of measuring instruments, emergence of unusual sounds and smells, etc. Do not forget that failure of such components as safety locks or spark plugs can be only a symptom more deeply of the hidden violation.

In this subsection rather simple scheme of diagnostics of the most often happening refusals is given below. The reasons of violations and their symptoms are grouped in a sign of their relation to functioning of any concrete unit or system, for example: Engine, Cooling system, etc. In brackets references to the corresponding Chapters and Sections of the Management concerning functioning of the components suspected of malfunction are given.

Regardless of the refusal nature investigations of its reason are always taken the identical basic principles as a principle:

Make sure of correctness of definition of symptoms of refusal. This means confidence in delimitation of the area of searches that it is especially important with the help in refusal diagnostics to other motorist who cannot adequately state symptoms of the violation taking place.

Try not to miss obvious violations. For example, if the engine is not started, do not hesitate to check availability of fuel in a gasoline tank (at the same time it is not necessary to take on trust statements of the owner of the faulty car). In case of refusal electric equipments first of all it is necessary to check a state and reliability of fastening of terminal connections of an electrical wiring, only after it it makes sense to get diagnostic units.

Try to remove a cause of failure, but not its symptom. Replacement of the discharged battery new will help to make start of the engine, however the reason of a discharge of the old battery taking place will remain not eliminated that will bring to bystry failure and new. Also replacement of the spark plugs (petrol models) thrown by oil will allow to restore serviceability of functioning of the engine for some time, however its refusal by all means will soon repeat (if the reason lay not just in application of candles not of that type).

Do not take on trust any statements. Remember that the "new" component can also be faulty, in particular if it long time lay in a luggage carrier - it is not necessary to exclude a component from the list checked only for the reason that it is new or is recently established. In case of neglect it is not necessary to be surprised with implementation of this recommendation when the cause of failure established at last is lying on a surface from the very beginning.
