There are many requirements for the periodic maintenance of the car that require you to be precise when it is completed, otherwise your car will encounter many problems.. What do you do exactly to measure the level of engine oil, tire air pressure or brake oil, how do you behave when changing spark plugs or when supplying radiator water, and what do you do when.. and at.. Here we give you valuable tips to act in any case.
1 Engine oil level gauge:
When measuring the level of the engine oil level, the car must first be in a horizontal level, and the engine should be run until its normal operating temperature, and then the engine should be stopped by closing the contact switch and waiting for about five minutes, then the oil gauge is lifted from its place in the engine and cleaned well with a piece A cloth that does not contain lint, then put it in its place again in the engine and raise and note the oil level, and it must be between the two marks by size and not be higher than the upper mark or less than the lower mark, and the oil level must not be measured while the engine is in a state of rotation because this will give an uncontrolled indication of the oil level motorized.
2 Tire air pressure:
When measuring tire air pressure, the tire must be cold, because measuring pressure after a long drive in the car causes the friction between the tire of the car wheel and the road to increase the temperature of the tire and thus increase the temperature of the air inside it, so its pressure rises, and then gives an incorrect reading of the value The pressure inside the tires, so it is recommended to buy a tire air test device (air tester), which is not expensive.
3 Brake fluid (fluid):
Failure to supply brake fluid (fluid) when its level is low in the brake fluid box, because a low level of brake fluid indicates the wear of the brake pads and gives the opportunity for the brake indicator light to light up in the dashboard, but when supplying brake fluid The lining wears out without giving any indication to the driver, as the brake lamp did not light up.
Brake fluid is only supplied when it is leaking or when any of the internal parts of the cycle have been changed. It must be strictly prohibited when using brake fluid because it has a severe impact on the car body paint, and if it happens and spills on the car body, a quantity of water must be immediately poured on the place of the brake oil on the car body.
4 Battery cable:
When changing or repairing any electrical parts of the car, it must begin by removing the negative battery cable from its place in order to avoid an electrical short circuit in the car, as well as when changing the battery, the negative cable must first be removed and then the cable ) the positive. And before removing any of the battery cable, you must first make sure that the ignition switch (contact) is in the closed position, and that all light switches are closed, so as not to damage the semiconductor parts in the electronic circuits of the car.
5 Engine overheating:
When the engine temperature rises suddenly, I must immediately stop the car in a safe place on the side of the road, and immediately close the ignition switch (contact) to stop the engine from spinning, then open the engine hood carefully and notice The following: The presence of any water leakage in the cooling cycle and work to prevent it or repair and change what is necessary, to ensure the safety of the cooling fan operation, and after the engine cools down, the radiator cap can be opened and to make sure that there is water inside, as well as making sure that the radiator water bladder is safe and that there is water inside it to the level What is required is to ensure the integrity of the radiator cap, to ensure the integrity of the radiator itself and the absence of anything blocking the air from it.
6 Supplying the radiator water:
When checking the radiator water, do not open the radiator cap while the engine is hot so that the pressure of the hot water does not rush to you and cause you burns.
It is preferable to supply radiator water through the radiator bag up to the level of the upper mark, and note that the water level in the radiator bag increases and decreases automatically depending on the condition of the engine, it increases while the engine is hot and decreases when the engine is cold, due to the increase in pressure and the imbalance that occurs in the radiator during hot and cold. When filling the radiator through its neck opening while it is hot, it waits until it cools down a little and opens the cover slowly, then runs the engine during the water supply so that the new cold water mixes with the hot water around the cylinders, so it does not cause damage (bending) or break inside the engine.
7 Walking on the road:
Avoid walking on the road behind trucks loaded with (sand, bricks, asphalt, drums, or any lengths such as iron or wood skewers, etc.), as all of this is liable to fall at any moment suddenly in front of you on the road, leading to unimaginable accidents. . Or at least it is possible for sand to fly on the front windshield of the car, causing scratches or pits, damaging the glass, or bricks falling on the ground and damaging the bottom of the car.
8 Changing the spark plugs:
Before changing the spark plugs of the car, it is necessary to blow around it well with compressed air to clean the dust that may have accumulated around it. The candle is located in the cylinder bush and expels it outside, in order to prevent the entry of dust into the engine cylinders and prolong the life of the engine, and then you can install the new spark plugs after making sure that the gap clearance is set to the recommended size.
9 Determining the brake sound:
When you hear a whistle when pressing the brake pedal, and you cannot determine the source of the sound, is it from the front brake? or background? Then drive the car at a medium speed, then put the gearbox in the neutral position, and gradually raise the handbrake while driving. If the sound comes from the rear brake, if not, it is from the front brake.
10 Static electricity: You
may feel a slight electric shock when you get out of the car door and your hand touches the car body, especially after a long driving period. Minimize it by wearing cotton clothes and staying away from clothes made of synthetic fibers and taking this into account in the driving seat as well, and when you leave the driving seat do not leave it suddenly but slowly, and before getting out of the chair try to hold with your hand any metal part of the car body to discharge your static charge through it.
11 Petrol stations:
Some petrol stations do not take into account the extreme accuracy in filtering the water from the petrol tanks. Electronic (sprayers) (it does not need to adjust the ignition because the ignition is adjusted electronically), this is evidence that you have filled your car with gasoline from one of these stations, so do not deal with it again
12 Lighting the battery lamp in the dashboard
When the battery lamp on the dashboard is lit with the contact open and remains lit even after the engine is running, this means that there is a defect in the charging circuit, either the battery is not receiving charging because of an internal defect in it, or that the charging regulator has a defect, or that the dynamo does not give The voltage required to charge the battery due to an internal defect, or the dynamo belt is loose and not tight or cut, in this case the car must be stopped and search for the cause of the defect, or the car is deposited to the nearest electric car.
13 The initial lubrication period of the engine:
While the engine is running during the lubrication period of the new engine or for which a general overhaul has been done during the initial period of operation (the first 1000 km), or a period of three weeks or a month (depending on your daily use), the following is recommended: Do not increase the rotation of the engine on High speeds, avoiding rapid engine start, not driving at high speed for a long time, and the vehicle must not be loaded with large loads, and no trailer should be towed during this period.
14 The color of the car engine oil:
Some motorists rejoice and brag in front of their fellow drivers that the color of their car engine oil has not changed after putting it in its engine and running the car for several kilometers. Therefore, its color must change, evidence that it is doing its job as it should, but if its color has not changed after several kilometers, this is evidence that the used oil did not do its job and left sediments inside the engine.
15 car engine exhaust colors:
Under normal operating conditions, the exhaust gases are supposed to come out of the exhaust gases without color, but there are three types of exhaust gases that come out of the car’s exhaust in certain cases, each of which has a different color from the other, and through it the condition of the engine can be diagnosed, if the color of the exhaust is continuous white with Under normal operating conditions and in all conditions, this is evidence that there is a leakage of cooling water into the combustion chamber and penetrates with it (which is evidence of a lack of water in the radiator and there is an internal leak, although there is no external leakage), and if the exhaust color is light gray tending to black, this is an indication I have to burn a large amount of fuel in the combustion chamber, which indicates that the carburetor needs tuning (adjusting the fuel with air) or the fuel is leaking involuntarily while not using the car. There is a combustion of lubricating oil in the combustion chamber, which is due to several reasons, which is evidence of the engine’s needfor repair.
16 Raising the level of the car on the ground
If you are complaining about the low level of the car on the ground, while ensuring the safety of the assistants and the springs, go immediately to one of the approved specialized centers and ask about the possibility of raising the level of the car off the ground, and do not take anyone’s advice to put attics on the springs from the bottom and from the top, Because it will actually raise the level of the car on the ground, but it will lead to damage to the assistants, and cause roughness in the luggage while walking.
17 Smell gasoline while driving:
When there are frequent complaints about smelling “raw” gasoline while driving, you must first make sure that there is no leakage of gasoline from the fuel cycle, then make sure that the engine is properly tuned, especially at high speeds, and then there is no venting. For the exhaust from the exhaust, then making sure of the good tightness of the interior vents of the rear trunk of the car, and finally making sure of the good tightness when closing the cover of the rear trunk of the car so that it does not leak the car’s exhaust into it.
18 Smell an electric smell while driving:
When you smell an unpleasant smell, especially while driving, or when the car engine is spinning , raise the car on a lift chute and look under the car along the exhaust pipe. Usually, the reason is that part of a plastic bag is stuck on the exhaust pipe with a temperature It burns on the pipe and melts on it and dries up when the pipe is cold and the engine does not rotate, and it burns again with the engine turning and the pipe of the exhaust pipe is hot, and so on, remove this part and clean its place well.
19 Detecting the status of the battery: It is
not necessary to detect the status of the battery by connecting the two ends of its poles with a cable or screwdriver, because this leads to the passage of a high-amp current that damages the internal battery parts, and breaks the active substance in it from the plates.
20 The right place to park the car:
Beware of leaving your car in the wrong parking places, such as placing it under the direct light of the public street lights, or placing it directly under the public electricity wires, or placing the car in the face of the direct thermal effect resulting from the factories, all of which have a negative impact on me. Car body paint.
21 Connecting your car battery to an external battery,
if necessary, to activate your car battery by giving it an initial charge through an external battery from another car using a connecting cable. At that point, one end of the cable should be connected to the positive terminal of your car battery (the battery is weak)
first, then the other end is connected to the positive pole of the battery Then one end of the cable is connected to the negative pole of the external battery, and the other end to the negative pole of your car battery.. This arrangement is very important to avoid damaging the electronic units in the car.
22 How to use the dash to start the car:
It is not permissible to insist on starting the engine of the car, when the initiator of the movement (the jogger) is not able to do so, which leads to the rapid consumption of the battery without benefit. But run the march at intermittent intervals so that the run time does not exceed (10 seconds) and then wait 30 seconds between each period and the next until the march starts to start the car engine.
23 Tampering with the electrical connections of the car:
In a car that contains electronic circuits, caution is taken when tampering with the electrical circuits, such as (installing a cassette, installing an alarm, changing the battery…etc…because any error in the electrical connections will lead to The electronic units are damaged and will cost a lot, so it is recommended to make any repairs or installations inside the authorized service centers.
