A few days ago, a person engaged incar repairPeople who have been in business for many years "jump out" and expose themselvescar maintenanceThere are some usual "flicker" tricks.
Change three filters for maintenance
We usually putair filter,Fuel Filter,Oil filterCollectively referred to as three filters. Many cars are maintained every 5,000 kilometers, and some repair shops recommend changing the three filters every time they perform maintenance, so that more profits can be made. In some repair shops, they always cut corners and only replace two at most. The air filter is often saved, and sometimes the steam filter is also omitted.
In fact, car manufacturers require more than 5000 kilometers to change once, but this also depends on the use and maintenance of the car. If the car refuels at a small gas station all year round, runs on country dirt roads, and travels long distances in the hills and hills, it should be changed every 2000 kilometers. If the car is in good condition, it can be changed every 10,000 to 20,000 kilometers when driving in the city. Generally speaking, the three filters are changed every 15000-20000 kilometers, that is to say, it is enough to change once after maintenance.
Three washes of maintenance
When the car is not easy to catch fire, it mayThrottleIf it is dirty, the repair shop will advise you to do a "three wash". Many small repair shops on the street now advertise "professional cleaning without disassembly".First use "professional non-disassembly cleaning fluid" to clean the air inlet, commonly known as "slinging bottle", and then the cleaning sectionValve,CarburetordetergentIt was sprayed on, and the oily mud was wiped off, visible and tangible, the time was not in vain, and the labor cost was 100 yuan.
After the three washes, the problem really disappeared. In fact, as long as the throttle is washed, most of the problem can be solved. Moreover, the real effective cleaning of the intake duct is to completely dismantle it, and wash it like a range hood, but the maintenance workers are very troublesome to do, and they think that the trouble is not profitable.
Maintenance exchangeSpark plug
When the oil volume increases, you can consider replacing the spark plug. The general repair shop will recommend replacing it at 20,000 to 30,000 kilometers. In fact, this is determined by the quality of the spark plug. The ordinary spark plug can be replaced once for 40,000 kilometers, and the platinum and iridium spark plugs can be replaced once for 60,000 to 80,000 kilometers.
Here is a way to save money: buy a spark plug by yourself, which costs tens of dollars, and the expensive one is only hundreds of dollars. If you find a medium-sized store, you can install it with your own eyes for ten or twenty dollars.
This has a greater advantage, that is, it can prevent the repair shop from putting the used spark plugs removed from other people's cars on your car.
Engine for maintenance
The engine is the heart of a car. People who don't understand cars are very afraid of the "heart disease" of the car. If the car emits blue smoke, it is a remarkable thing.
Send it to the repair shop. People say the engine needs to be overhauled, so we have to obediently hand over the car to them.But what they did, maybe just deal with the valveOil sealAgeing,Piston ringSmall problems such as abrasion and jamming can be solved.
If you are driving normally in a city, the engine will have to be overhauled after 100,000 to 150,000 kilometers. Let's talk about it when you feel that the car is boring and can't raise the speed.
Oil change for maintenance
Repair shops also have ways to save money, and changing the oil is an opportunity.
Generally, Jetta needs about 4.5 liters of oil, while Fukang needs at least 3.2 liters, and Alto needs about 3 liters. The standard is to fill the oil to the upper limit of the bend zone of the dipstick. But even if you see the maintenance worker add the oil to this position with your own eyes, your seeing is not necessarily believing. Because, just like doing magic, what he lets you see and believes must be prepared first, and his preparation is when the old engine oil is drained.
For example, Jetta, they usually only drain 4 liters of engine oil, so that when injecting new engine oil, they can save half a liter. Who doesn't let us have the habit of taking the remaining engine oil away.
For other problems of the car, the diagnosis of the repair shop is even more indistinguishable. Unless we live to grow old and learn, we can’t deal with it. (Edit Jin Chao)
