Some questions about car maintenance

Transmission oil is the role of lubrication, cooling and power transmission, but different decided three main gearbox structure they need lubrication in different ways, thus determines the transmission they require the use of different properties of oil. Manual transmission gear oil: oil is usually manual gearbox oil said, only lubrication. USA Petroleum Institute will vehicle gear oil according to the using performance is divided into GL-1, GL-2, GL-3, GL-4, GL-5, GL-6 six. The emphasis on the overloading of the GL-1, GL-2, GL-3 have been eliminated in the market, and the current domestic car use generally were GL-4, GL-5 (GL-6 bus is used). From the product characteristics, the most intuitive is manual gearbox oil is bigger than the automatic transmission oil viscosity, the replacement cycle generally than the automatic transmission oil is shorter, the majority of household car at 4-6 million kilometers to replace the manual gear box oil.

AT gearbox oil: automatic transmission oil is special, it has two functions, in addition to the planetary gear lubrication, cooling, more important is to make is to transfer power, so its viscosity than manual gearbox oil as "thick". But its main role is to hydraulic transmission, so very good fluidity, anti bubbling ability than manual gearbox oil stricter requirements.

Automatic transmission of different types of oil is not mixed with AT gearbox, because different types of oil flow rate, density, dynamic and static friction properties, thermal expansion coefficient are different. Some manufacturers is according to the characteristics of AT transmission is introduced with matching gearbox oil, suggested that the owner or in the 4S store replacement or purchase the corresponding models were replaced, do not replace other models.

CVT gearbox oil: CVT gearbox oil essence and AT oil is similar, but it is also a special oil, because the CVT transmission is the steel chain transmission characteristics, need oil velocity, friction, coefficient of expansion is different, so you can't use AT gearbox oil instead of. Relatively speaking, it is the AT automatic transmission oil to dilute some, also has the certain prevent damping friction drive chain slippage.

Lubricating oil on three main gearbox, between absolute cannot replace and mix! Oil AT gearbox similar oil and CVT gearbox oil also can not replace each other, if it replaces the use of the short time, although not what impact, but a long time for the mechanical wear is not recoverable.

In the replacement after the engine oil, the need for rough with the engine oil dipstick, so if it adds a car go, will find that just added to the bit oil shortage phenomenon. This is because the gap between the many parts in the static gas after not inject new oil, such as oil guide hole, so be sure to start the engine again after the measurement in oil after the oil, make full to the level corresponding to the. At that time usually appear a small amount of fuel deficit phenomenon, again added to the standard position. Recommendations go to the 4S store maintenance when the attention of the details.To do better on cars, you can know more car tools like Launch X431 IV and t300 key programmer.

Automobile insurance misunderstanding

I believe many of my friends in the choice of insurance will and insurance salesman said, my car to the insurance, so most of my friends think of car to the "all risks" get "lost the whole". After understanding, in fact, the word "all risks" in insurance companies and state law does not exist, only a habit of people. People used to several major categories include cross strong insurance, commercial three party insurance, non deductible insurance, car insurance, pilfer, car insurance and other personnel, generally referred to as "". Therefore, "all risks" is not equal to the whole.

Your time in the vehicle insurance insurance insurance insurance companies must pay attention to the related definition for different categories of interpretation and the scope of the claims, or claims is the premise of what. Do not know if rushed to buy insurance, even if the purchase of the so-called "all risks", also will not get full compensation. My suggestion is that you can use based on its own, according to their own actual situation to select the security risks, so that not only can provide convenience for your future claims, but also save a part of the vehicle insurance costs.

Prior understanding, no purchase wading insurance vehicle when the engine inlet, is unable to get insurance company claims, but in fact this is not entirely correct. Because some of the provisions of the insurance companies have a clear explanation for this problem, car damage buy insurance is covered wading insurance and risk of spontaneous combustion of additional insurance, if not needed can be individually removed.

Believe that every car friends do not want the vehicle is stolen or destroyed in yourself, never mind, as long as you can meet your claim the insurance conditions, insurance company will complete compensation you deserve it. And here there is a problem, that is the vehicle insurance prices higher future can get the amount insured when the vehicle?

Of course, the answer is negative, if your car insurance, so the vehicle insured amount will be in accordance with the actual vehicle sales price, but if you are a continued insurance, so the vehicle insurance amount will be in accordance with the current sales or second-hand car sales prices for insurance. So you when the insured vehicle insurance amount should be the actual value is determined according to the insurance of vehicle insurance, full insurance at the time of the accident, ensure to get reasonable compensation. Don't over insurance, because excess insurance and can not be excessive compensation, it is just a waste of money.

A lot of the old car friends may have encountered such a problem, is often the insurance company refused to be in the purchase of insurance, in fact there is a misunderstanding, there are difficulties and not buy all of the categories, here that is car caustic danger. Because the old car loss is difficult, residual determination is also very fuzzy, other related repair parts are less, so most of the insurance company is not willing to underwrite such models. In addition, the purchase of insurance and three party insurance is not affected by the use of life. But for years long old models, related premium is a floating.

When after the accident, should be responsible to compensate, be claims procedures go payment to 4S shop or trusted repair shop for maintenance after. But many owners have encountered this problem, is to request the other party to repair place, this is in order to reduce the cost of repair, in not trusted repair factory repair is difficult to ensure the quality of repair, so the encounter such a situation must not easily promised. Because both each other or other insurance companies have no right to specify the place.To do better on cars, you can know more car tools like vas 5054a and fly100.

After adjustment, the small car field test items from the original "training of 10, test 4" changed to "training and exam are 5", that is, reverse parking ramp designated parking and starting, side parking, curve and turning right. And the future site examination will replace the existing benchmarking with the ground marking, more close to the real road scenes.

Through the survey found, small car "two" in the test subjects exam project targeted not strong, such as through continuous barrier, through unilateral bridge in real life is not common, the majority of students back formula test. In order to improve the practicability of examination, the new regulations to optimize the small car "two subjects" test: a simplified pile test line, instead of backing storage, cancel the transfer request. Two is the hundred Mega downshifts, rolling road, adjusted to the actual road test. Three is the speed limit to cancel the door wide, through successive obstacle, unilateral bridge 3 projects through. In addition, "two subjects" field test, will be used to delimit line to replace the existing benchmarking, prevent the trainees to benchmarking as a reference point of reciting the pithy formula and test, the test is more close to the actual scene.

The new regulations "will be a theoretical examination subjects is split into two parts. The first part mainly examine the law of road traffic safety, traffic signals, traffic rules, still as subjects; the second part as a safe and civilized driving test project, in the actual road test, evaluation of safe and civilized driving requirements, complex conditions of safe driving knowledge, enhance the driving of safe and civilized driving knowledge the understanding of memory.

After the adjustment of large and medium-sized passenger car "two" test subjects from the original "training of 10, test 6" is amended as "training, examinations are 16". The new simulation of continuous sharp curve tunnel, near water, cliff, on snowy,rainy days, wet and slippery road, emergency disposal 6 Compulsory Project of large and medium-sized van driver test.

Good maintenance play an important role in car,hot car tools as AUTOBOSS V30 ELITE and UCANDAS VDM are necessary.

Beijing first pilot test field will be compulsory project to 10 items, including simulation sections of water, a U-turn, near the cliffs on the edge of road, railway port 4. Next January 1st, the examinee should at least driving a vehicle traveling 20 kilometers, and practice in the simulation and test on the road. At present, Beijing other qualification training car key drivers driving is rebuilding training field.

The fuse of automobile

The fuse is its official name is called, the real fuse (hereinafter as easy to understand as a fuse), the most basic function of fuse is when the circuit current anomaly and exceeds its rated current fuse to circuit protection function. The fuse has two important working parameters, one is the rated current; one is the rated voltage, use the time to choose to fuse the corresponding according to current and voltage circuit.

In the structure design, insert the general vehicle fuse with fuse, with engineering plastic shell, wrapped in the melt structure made of zinc or copper, the metal melt and pin connections. Insert fuse specifications car usually 2A to 40A, the ampere fuse numerical will be noted in the top. If the fuse burned out let a numerical illegible words, we can also be judged by its color, the international standards: 2A, 3A, 4A grey purple pink, orange yellow, 5A 7.5A, 10A 15A Coffee color red, blue, yellow, 20A 25A, 30A green, colorless and transparent 40A deep orange.

Because many parts and electronic equipment on automobiles, and each device will be equipped with a fuse, so in order to facilitate future repair, every car in the design stage, designers took automotive fuses are concentrated in one place, but this place is called insurance box. Generally a car has two insurance box, one is located in the engine compartment, responsible for automobile external electrical fuse, such as engine control units, horn, glass cleaner, ABS, headlights; another in the left near, management of car electric appliances, such as window lifter, airbags, the electric chair, cigarette lighter.

Because the car is on the box, under normal circumstances do not deliberately maintenance, but need to pay attention to is the protection of insurance cover, the fuse is lost, don't let the fuse is exposed outside, so as to avoid the fuse circuit. In addition to cover the fuse, also can not use other materials to replace, because the insurance box is made of full consideration of the insulation and high temperature resistant, free to use other material covering the fuse will have the danger of fire.

How to do it yourself replacing the fuse? Find insurance box position. Side fuse box cab is generally located in the control station near the door or on the wheel below; launch insurance box inside the cabin in a vehicle engine compartment edge. Check fuse fuse fuse. According to the table to find the position fuse box lid of the table we can find the position we are looking for.The remaining steps is the use of cars equipped with special tool pull out the damaged fuse, fuse can be put on standby. At present, the vehicle using the insert fuse no positive and negative points, so as long as you pay attention to when replacing the fuse fuse size and amperes can.

If you want to know more auto repair, there are some hot car tools like volvo vida dice and super vag k can plus 2.0 which can help you.

When replacing the fuse, the fuse must choose the correct amperage, do not increase the current specifications of fuse at random, but can not use wire to replace. Can not use wire replacement is easy to understand, why not use large current specifications of the insurance? Of course, but also for electrical protection in mind, can work steadily in the current conditions of 1A appliances, in greater than 1A with electrical appliances may not work properly.

The Audi A4L MMI system

Audi MMI system similar to the BMW i-Drive and Mercedes Benz COMAND APS system, which is a combination of vehicle system operation and control, the user can adjust the vehicle through a number of information system, is one of the most advanced car entertainment system. A new generation of MMI system also has the car voice dialogue function, the driver can to voice commands to quickly open / close inside a function, or quickly switch as many as ten preset navigation destination.

Audi A4L on the set of the Bluetooth system can be said to be the function into full play, whether it is equipped with a degree of clarity or mobile phone calls with the vehicle, can be said to be the top one among the same products.

When it comes to multimedia entertainment system, I believe that the development of each manufacturer would be this function emphatically, more than 80% of the driver will listen to the CD or the radio in the driving process, so a lot of people in the purchase a car when the multimedia entertainment system into account. Audi is no exception, the new A4L MMI system provides six kinds of playback source, which also has a built-in approximately 20G of hard disk, you can copy the favorite songs to your hard disk.

Get Launch X431 V and gm tech 2 these auto tools to do more on car maintenance and repair.

In addition to the Jukebox function, Audi MMI this Bluetooth play function is also very practical, via Bluetooth system and external playback source are connected, can realize the wireless music. In addition, thanks to Bang & Olufsen sound help, make Audi multimedia playback and reached a high level.
