Repair and operation of the car

Whether all as it should be with the car engine? Can it is time save money for performing computer diagnostics, and even for repair? To answer these questions to you will help several advice of the autoengineer, it is a lot of years engaged in repair of import cars.

Before seeing a doctor, each of us is engaged in self-diagnostics. At the same time we do not do ourselves roentgenoscopy, we do not use the electrocardiograph and other sophisticated devices. Simply we feel a forehead, we examine a throat, we listen whether sizzles in a breast, whether swells out a stomach, whether mangles a waist. From devices traditionally we use thermometers and, maybe, the watch at measurement of pulse.

Here so, simply, we define whether the organism normally functions. And it turns out!

The car engine – the same organism. For its exact diagnosing and treatment there are many cunning devices, devices and tools. Various exact techniques and receptions demanding thin knowledge of the internal device are used. We plan to tell about them in detail in the near future.

For a start we suggest to master things, simpler for understanding.

Let's try to understand what it is necessary to pay attention to, operating the car: what needs to be felt, where to look, where to listen and, maybe, even to smell to understand how the engine feels. You do not want to study together with us – get one hundred dollars from a purse and go to computer diagnostics. Automobile "medical care" paid!

Present that you the kind doctor. Having entered into chamber (garage), approach the patient (car), surely greet, tell it several tender, calming words and suggest to undress to a belt (open a cowl).

Begin with external survey of the engine. Remember that nothing reflects internal wellbeing as the pleasant, well-groomed, radiating with health appearance.

Strong general impurity of the engine, as well as existence of intensive local leaks, on the contrary, testifies about reeled health. If in the evening, leaving the car, you providently enclosed the blank sheet of the newspaper under the engine, take out it and examine. Leakages of oil and other operational liquids in a night will leave marks on which you will be able to establish sources of leaks on the newspaper and to define their intensity. Than it is higher, those need rather to take measures for elimination of malfunctions.

The following step – check and bringing to norm of level of all operational liquids. First of all we are interested in engine oil and cooling liquid (antifreeze) as their shortcoming most
