Many car owners and friends complained to editors that their car is only two or three years old, and there are more and more minor problems, and they are increasingly turning to a car repair shop, which is very troublesome and costly.
I knew an old man in a car repair shop who has been repairing cars for twenty years, and last weekend I was at his house for dinner and talked to him about this topic. As expected of old driver, when I returned, I parsed words of old man as follows, I think it will be useful to everyone:
The car repair shop master mentioned that quality of cars is getting better and better now. Apart from collision damage and vehicle aging, other problems are caused by owner's bad driving habits. The master also said that I repair More than half of cars passing by in this condition. 10 reasons please keep in mind!
1. Insert key and light directly
Get in car, insert key, turn on ignition, shift into gear and drive away. I think this is a habitual action of many car owners. However, this is a bad habit that shortens battery life, makes it difficult to start engine and contributes to formation of carbon deposits. The key position when turned on is usually divided into LOCK (lock), ACC (connect some electrical appliances), ON (connect all electrical appliances in car, and computer starts a self-test), START (connect starter, start car). The correct way to use it is to complete electrical self-test in gear and then turn on ignition to start car. How to pass self-test if it is a car with a one-button start? Do not press brake pedal before getting into car, press one-button start button and hold it for about 3 seconds, then release it to start self-test, and then press brake to start after 6 seconds.
2. Engage brakes and clutch before hitting bottom
Also, many people have a bad habit of shifting gears before car comes to a stop. This method of operation has a great impact on gearbox. Sometimes once or twice may not affect car, but after a long time, it will cause permanent damage to gears in gearbox. Also, if you change gears without pressing clutch in a manual transmission car, it's easy to hit gears and damage transmission, so no matter how impatient you are, don't rush!
3. Turn off fire and leave air conditioner on
It's easiest to forget details, such as turning off engine without turning off A/C, which will put a lot of stress on starter and engine next time you start car and can damage those components. It is best to turn off air conditioner one to two minutes before turning off engine, two to three minutes after starting car, wait for engine lubrication before turning on air conditioner.
4. Frequent use of combo switches
I don't know if any riders have had this experience, flash of light seems to be able to experience thrill of playing shooting games when I was a kid, which makes people feel good, but frequent switching increases chance of damage combination switch. Because at moment switch is turned on, current through switch contacts is much higher than usual, and if ignition works in a half-closed and half-disconnected state, then contacts can be burned by electrical sparks.
5. Kill steering wheel
Many car owners have a bad habit of turning off steering wheel without even hearing sound of bottom and collision. However, turning off steering wheel frequently will cause car's steering hydraulic pump to fail, and this will exacerbate aging of hydraulic pump belt after a long time. , The lift pump is broken, which also affects steering mechanism.
6. Forget to turn off windshield wiper
My friends in north often encounter blown wiper motors, often due to rain or snow day before, and wipers left on after parking and forgotten to turn off. I started car next morning, but windshield wiper froze up without knowing it, eventually causing wiper motor to burn out. If next time it is sunny, a layer of dust and sand will inevitably accumulate on windshield, and frequent dry scratching will damage wiper rubber and even scratch windshield.
7. Car wash under hot sun
It gets warmer again and car gets hot when parked outside. Many car owners think that car is too hot inside, so they first send car to nearest car wash. But it will cause a lot of damage to paint of car body, and often such acceleration leads to aging and cracking of paint. And if you go to car wash immediately after driving at high speed, you can even damage tires.
8. Refuel when fuel tank runs out
It is said that recharging batteries of electronic products can prolong their life. Drivers who listen to rumors also like to wait for fuel level warning light to come on before filling up. Since fuel pumps on EFI vehicles use fuel itself to cool, if oil level is too low, fuel pump can overheat or even burn out. Please don't be smart my friend!
9. Parking is uneven
Parking spaces are tight right now and in many cases we can only park on bumpy spots to park. However, parking in this way for a long time will cause all four wheels to fall too much, causing deformation of frame and even affecting closing of car door. In addition, in non-standard parking spaces, wheels often have to return to their normal position after parking, which also damages tie rod and dust cover and affects steering system.
10. Long hot car
In fact, according to current car manufacturing process, hot cars are no longer needed. However, there are still many car owners who have habit of warming up their cars, even for a long time. After such a long time, it will affect engine and three-way catalytic converter, and waste oil and pollute environment. environment. If you get off half way after driving for more than 1 minute, it is recommended to turn off engine.
Do you think master's experience is correct?
