Big mistakes when maintaining cars

Car Maintenance Mistakes To Avoid

Hello friends, today I would like to share with all of you who have been using cars, especially those who have just learned to drive, after you buy a car and you use it, the following mistakes are made. How do you use the car to the maintenance period properly, how to standard.

So I would like to share with you my experiences. The following are common misconceptions that do more harm than good that car users in Vietnam often make when maintaining their cars:

1. Oil change at first 1000 km
Most people assume that the engine oil must be changed at the first 1000 km because of fear of machining metal chips, but that is not entirely true, because the parts manufactured for modern cars today are very clean, technological. Crafting is getting more and more precise, and screws are slowly disappearing, in favor of glue or nothing at all. Therefore, according to the recommendations of car manufacturing companies, people should change the oil at 6000 km, diesel engine at 5000 km, for gasoline engines.

2. Run to the end of the new car
Most car owners wonder about running to the maximum, ie running smoothly, their new car is like, in fact, today's car manufacturing technology does not need to run to the maximum, but car manufacturers Only recommended to run at 80% load, maximum vehicle speed for the first 1000 km.

3. Keep the engine clean
Today's cars apply a lot of electronic technology, for engine control and support equipment, so having water in the engine compartment can cause damage to equipment. electronics mentioned above. Even in developed countries like the US, people still get to wash the engine compartment, but it is accompanied by a warning that customers are not responsible if the engine is damaged.

4. Requires maintenance in maintenance-free assemblies
Drivers are often worried, when they go to the maintenance company, they see that the workers are done very quickly, so they often bring them out to make extra work to be sure, specifically here are some parts that are free of maintenance, only check for damage, then replace like bearings, collars, batteries, ABS, AEFB brake systems, if you deliberately maintain the possibility of these items being damaged, they are quite high.

5. Inflating tires with high pressure like motorbikes
Many people who use cars often think that motorbikes weigh more than 1 quintal, but also have to pump 3-4 pounds per cm2. So, cars weighing tons should at least be inflated with motorbikes, but the truth is that according to most car manufacturers, tire pressure of only 2,0 - 2,5 kg / cm2 is enough. both durable and smooth running.

6. Using Xenion bulbs instead of Halogen bulbs will be brighter
The car's glare is designed to match the very small luminous point of the Halogen bulb to help focus the light well, minimize the excess light rays that cause glare for people in the opposite direction, do not change the Xenion bulb's light point This lamp is many times larger than Halogen bulbs, so the light is not focused and very redundant, causing glare. In many cases, the lighting ability is not equal to the original Halogen bulb and car owners are easily deceived about the eye-catching color of the Xenion bulb, not to mention the glare that can be damaged or broken due to the temperature of the large Xenion bulb in the electrical system. Although the manufacturer always advertises that Xenion bulbs are more energy efficient, cooler than Halogen bulbs.

7. Soundproofing measures for cars are clearly effective
Noise canceling is only psychologically effective for car owners, but it's not ineffective at all, but it certainly won't be worth the money you've spent, any car manufacturer does. There is a criterion of good sound insulation, of course, but you have to spend a lot of money on dismantling the entire interior and details related to noise-proof work, and additional money for materials and wages.

8. Effective fuel-saving equipment and materials
According to the evaluation and experiment, some material equipment can save fuel to a very small extent, and compared to the cost that the car owner spends, it will suffer a loss. Moreover, if it's really economical, the companies will definitely buy the copyright or research, develop and equip their cars themselves, not let others do it instead, you should remember the fuel economy criteria. whether today is one of the criteria determining the company's survival.

9. Turn off the air conditioner before turning it off and turn it on again after starting it
This is only true for older cars or cars with air conditioning systems made by non-professionals, and it is passed on by word of mouth from experienced drivers who are used to driving wrecked cars. The air conditioning system in today's cars will not work during start-up, but only after the engine has started for a few seconds.

Another mistake of users is that the car air conditioner is like a home air conditioner, the car air conditioner only runs when the engine is running and its capacity is many times larger than the average home air conditioner. If the diesel engine is filled with the wrong gasoline, the engine will be completely melted, if the gasoline engine is poured the wrong oil, it will be okay, the oil will not burn, the gasoline will only need a little bit of fire to burn fiercely. So if a motorbike is filled with the wrong gasoline, it will explode like a bomb based on the ignitability and self-ignition of these two fuels and based on proven facts, everything is the opposite. If the diesel engine is mistakenly filled with gasoline, if you miss a few tens of kilometers, don't worry, just add fuel to travel and it will be fine. However, it's not that it's not harmless, but the damage is not significant, but you guys with gasoline engines should be careful. Reality has proven that gasoline engines that run DIEZEN oil without early detection can damage the whole engine and many other ancillary equipment.

Anti-rust tips for cars
Rust is inevitable when using a car for a long time, because every car has at least some metal parts what you can do is prolong the life of metal parts by taking measures. Simple but effective with small rust spots, you just need to brush with sandpaper with a brush, then prime and repaint to match the overall color, without spending too much time and effort. You have prevented corrosion from spreading on the car, larger rust spots will require more investment depending on the severity, if there are holes appearing in the body where the rust is this is the real problem, In this case after removing the red rust spots you need to fill the hole with plastic filler or glue, after this step you need to wait for the filling to dry and then sand it, so that the contours of the hole match with the around the body of the car, then you prime it to dry and then paint the appropriate color, it's more complicated but you need to follow the right steps to complete the repair.

How to prevent?
Electroplating, also known as galvanizing, involves the process of coating the car's body in a molten zinc base, which, when dry, protects the metal from rust attack. If you have a garage, pay attention to keep the humidity at a minimum to prevent oxidation, you can use a regular dehumidifier in the garage, there are many special anti-rust devices for for cars is usually applied with a pressure sprayer like professional car washes do.
Paint the entire car to prevent rust formation because the paint layer is the physical barrier between the metal and the outside moisture.

When riding in hot weather, drivers should pay attention to the tires, battery, cooling water system, air conditioning system are the parts on the car that are most susceptible to damage in the summer. The sun is bright, harsh, and the temperature rises in the summer, which directly affects some parts of the car such as the cooling system or the air conditioner, in addition, the heat also directly affects the car. tire pressure and cabin.

Due to high temperature, the cooling system will have to work harder, cooling water will lose faster, moreover, the cooling system is one of the important parts to help cool down, release heat, and heat the engine. Therefore, it is necessary to regularly check the cooling water, check the pipes, water tanks, and rubber parts, if cracks are detected, they need to be fixed or replaced. In addition, attention must be paid to engine oil, gear oil, hot weather causes the cabin temperature to rise up to 60 degrees in the sun, so the need to use the air conditioning system also increases, before entering. In the hot season, the car should be checked for the cooling system, clean the outer surface of the water tank, and the outdoor unit, check the amount of air conditioning gas is sufficient or lacking and the operation status of the outdoor unit.

In case the air conditioner works normally, there is no loss of gas or cold in the summer, so clean the hot rig thoroughly. The hot rig will help deepen the cold, when cleaning in the sun, you need to open all the doors, start the engine for a while to let the heat out, help the car cool faster, gluing anti-heat glass is also a solution to the exchange process. efficient heat exchanger. In particular, it is also necessary to clean or replace the air conditioner filter according to the standards of some car manufacturers, the air conditioner filter must be replaced every 15000 km, check the hygiene after every 5000 km, the tires are a set. Direct parts, in contact with the road surface also need care. Regularly, check tire surface, tire pressure.

Note : Check tire pressure, should be done when the tire is cold or according to the owner's manual. Rotate the tires every 10.000 km according to the company's standards, so the tire should be about 0,1 kg younger than the standard.

For example: 16-seat tourist tires, 2,2 kg / cm3 standard, the tire pressure should be at 2,1 kg / cm3. Because the sun contains ultraviolet rays that damage the paint of the car, the exterior of the car is also affected, by the sun. In addition, dust mixed in the air, salt, and acid rain to protect the car's paint must also be regularly washed, limited to parking in the sun and not covered with the car.

High temperatures increase the rate of chemical reactions inside the battery, leading to overloading and shortening the life. In addition, the hot temperature also evaporates the liquid inside the battery, in order for the battery to operate effectively and durable, it is advisable to check the electrical system, if the battery is the type of water that needs to be regularly checked, especially in prolonged periods of heat and add more water if necessary, keeping the cleaning between the poles clean.
