When choosing between a Chinese car and a native LADA, Russian car owners increasingly prefer to “stick to their own car” or opt for a used car of a well-known brand. However, time has power over everyone, even seven-wire “Japanese” cars, so for the normal operation of a used car you need to know some details and understand maintenance. Details are on the AvtoVzglyad portal.
Buying a new car today is a great success and a reason for jealousy. A good used one is an achievement. In this cabinet on four wheels, as a rule, many skeletons are hidden, and the higher the number on the odometer, the more of these “highlights” there are.
It is extremely difficult or even impossible to identify many of them at the time of inspection and purchase, so if you buy a “secondary”, you should be calm about all kinds of misunderstandings: roughness and minor repairs are “included in the price” and will take place within reasonable limits, if you do not waste the nerve cells in vain. And most of the work can be done independently or very cheaply.
Doesn’t start when the engine is warm, so you turn the starter for a long time and only ‘overtake’ when the accelerator pedal is depressed? Frankly, at first glance it sounds promising in terms of rubles. If you come to the service center with this symptom, prepare for significant costs.
In order not to spend too much – at gas stations they want to change everything gradually, forcing the car owner to diagnose the car himself and gradually replace suitable components with new ones – it is easier and more efficient to do some of the work to do yourself. Diagnostics, for sure. This way it will be faster and cheaper.
Difficulty starting the engine is usually a symptom of a lack of battery power. If the battery is still alive, fresh and full of life, which is easy to check with a simple and inexpensive multimeter, then you need to dig for the points where the mass attaches to the body and engine. There should be no rust, dirt or corrosion, but a usable and clean contact, lubricated on the top with a special fluid, is a must. How much does the first step towards your goal cost? The exact price is 120 rubles, or a tube with funds for the preservation of the terminals. You’ll probably find a stiff brush and a piece of sandpaper around the house.
Did the “stone flower” not appear? The problem has begun: we turn to another possible source of our headache: the camshaft position sensor (CPR). Over time it gets dirty, the wires rot, the terminal falls apart: clean, inspect and reassemble. The ideal option is to find a colleague with a similar machine and test it on his known good device. Fortunately, as a rule, the same sensor is unscrewed within a minute and a half. By the way, the same service can be obtained cheaply and sometimes even for free at a car dismantling station.
Is the sensor alive? Then our path is to the starter, which gives rise to very similar symptoms, indicating the need for a rebuild. Moreover, the entire unit does not need to be replaced: the starter is the case when a bulkhead is better than buying a new unit. In three out of four cases, difficulties in starting with a warm engine indicate fatal wear of the bendix, which must be replaced in the same way so as not to get up twice (read – do not take off), swing the brushes, while at the same time performing a “general cleaning”. Next is installing and testing systems. Let me guess: did everything work properly?
