Repair and car operation

The owners of cars who are carrying out procedures of routine maintenance of the car it agree the present Management of the schedule resulted in Chapter 1 will be extremely seldom compelled to address to materials of the given Section. Reliability of knots and the components established on modern cars is so high that at timely performance of replacement worn out and failed as a result of ageing of a material of details the probability of their sudden refusal is smallest. Refusals seldom occur spontaneously and usually are a consequence sometimes of long development of defect. In particular, refusal of mechanical components practically always is preceded by occurrence and development of the characteristic symptoms shown at times for many thousand of kilometres of 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 basic knots and car systems, or are easily replaced directly on the car in road conditions.

Basic step at revealing of the reason of any refusal is the choice of a point of the beginning of searches. Often the reason appears enough obvious, however in certain cases it is necessary to work, making small investigation. The motorist who has made half-dozen casual checks, replacements and corrections quite has to find out a cause of a failure (or its symptom), however such approach in any way it is impossible to consider chance reasonable, in view of its labour input and aimlessness of expenses of time and means. There is a quiet logic approach to search of the failed knot or a component much more effectively. Necessarily it is necessary to take into consideration all preceding breakage, sometimes insignificant symptoms and guarding signals, such as loss of capacity developed by the engine, change of indications of measuring instruments, occurrence 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 of the more deeply latent infringement.

More low in the given subsection simple enough scheme of diagnostics of most often happening refusals is resulted. The reasons of infringements and their symptoms are grouped on the basis of their relation to functioning of any concrete unit or system, for example: the Engine, cooling System etc. In brackets are given references to corresponding Chapters and the Sections of the Management concerning functioning of components suspected of malfunction.

Without dependence by nature refusal in a basis of investigation of its reason identical base principles are always put:

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

Try not to look through obvious infringements. For example, if the engine is not started, do not hesitate to check up fuel presence in a petrol tank (thus it is not necessary to take on trust statements of the owner of the faulty car). In default electric equipments first of all it is necessary to check up a condition and reliability of fastening клеммных electroconducting connections, only after that it makes sense to get diagnostic devices.

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

Do not take on trust any statements. Remember that "the new" component also can appear faulty, in particular if it long time has lain 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 performance of the made recommendation, when the cause of a failure revealed at last will appear lying on a surface from the very beginning.
