Acquisition of spare partsThe important role at repair work is played by use of spare parts and the quality expendables intended for your car.
As a whole spare parts can be subdivided into two big groups:
Original spare partsThese spare parts extend through official representations of the companies manufacturers of cars, always have original packing and the corresponding marking. Thus quality of a detail is guaranteed by producers of the car. In warehouses of official representatives of the manufacturing company usually there are in the range all spare parts for this car. If any detail is absent, it in the shortest terms can be put from the central warehouse.
Stereotyped spare partsDefinition "stereotyped" speaks nothing about quality of details. It means only that they are on sale not in firm packing of the manufacturing company of the car and extend not through official representative offices. The main frame of this group is made by the known manufacturing firms of spare parts delivering details to assembly lines sometimes at once of several automobile plants. In a type of high capacity of the production similar firms provide also delivery of spare parts for sale in the free market. Such details have packing and marking of the producer of the spare part and at all do not concede on quality to original spare parts at much lower cost (the difference in the price can reach 50 %). However, the range is usually a little more modest in view of that for free sale try to let out only the most running details using the greatest demand. Many wholesale western merchants in spare parts use own packing, buying the big range of stereotyped details in large lots directly from producers and selling them under own trademark. Stereotyped spare parts, as a rule, extend through independent shops of automobile accessories, automobile repair shops and service stations.
It is necessary to give special attention to quality of acquired spare parts. Try to avoid purchase of absolutely cheap details (in comparison with original and stereotyped known firms) as often they do not correspond to standards of quality and safety. If installation of a second-grade decorative molding is capable to affect negatively only appearance of the car, use of low-standard brake blocks / the oil filter bears threat of safety of traffic and can be at the bottom of serious damage of the engine. Thus costs of regenerative repair by time many times over exceed saved upon purchase of a cheap detail the sum. Told means that it is necessary to try to use official representations of the company manufacturer of the car (original parts), or well proved suppliers of stereotyped spare parts.
There is also a possibility of acquisition of the restored details, thus the old, failed element usually is given in exchange for the restored. This approach is most productive at replacement of such difficult, expensive components, as knots of the power unit, the generator, a starter, etc. The marked service is provided both official representations of the manufacturing company of the car, and independent suppliers of spare parts and allows to cut down essentially expenses on car repairs. Thus the firm offering the restored unit, usually gives on it almost same guarantee, as on the new.
Identification of spare partsAs it was already mentioned above, the companies manufacturers of cars, being typical representatives of a mass production, aspire to improve constantly the production, constantly making to a design of let-out models certain changes and additions. Can happen so that within one series and one option of execution of the car some knots and units in insignificant degree will differ from each other, and the spare part intended for a complete set of cars of one, for example, of earlier year of release will not be suitable for others, let out later. In view of told, at acquisition of spare parts it is very important to provide to the seller the fullest information on the vehicle.
Besides the standard data set, including year of release, body type, option of execution of a body, number the chassis (number VIN), engine number etc., the seller can interest the following data:
a) Transmission type;
b) Type of system of supply of fuel;
c) Whether any additional equipment (for example, an additional heater, more powerful generator, the conditioner, etc.) is established on the car;
d) Whether the catalytic converter enters into a model complete set.
e) An installation site of an acquired detail;
If for any reason the documents reflecting listed data, no, it is meaningful to consult previously specialists of representation of the company manufacturer of the car.
Sometimes, buying this or that spare part, it is useful to take with itself for comparison an old detail subject to replacement.
