Huang has 15 years of driving experience of the master said that the car must be carefully maintained, and only careful maintenance, can be handy for owners of any ride. This, the reporter interviewed specifically vehicle maintenance professionals Shihai Arthur, let us look at the points of experts to vehicle owners that matter.

Body paint beauty

Dew fall more if the car has significant scratches, paint should be promptly dealt with so as not to scratch parts of damp rust. Summer is rainy season, rain water contains acid rain will lead to corrosion paint, car paint will inevitably be oxidized, and the summer of UV radiation on human skin is not only caused great harm to the body as well. Sunscreen even when the owners do the work, but still able to escape the body’s surface finish of radiation damage. Therefore, in the summer and autumn when seasonal, to the body were from the cleaning and polishing to waxing, sealing glaze and a series of cosmetic maintenance is essential. Of course, but also for their vehicle owner’s vehicle condition, if the paint is still very bright, to the body to fight wax on it. And cosmetic results after the glaze with the duration and quality, grade level also has a very close relationship, so owners have to pick the car of beauty products.

The engine compartment and brake maintenance

Into the fall, should always check the engine compartment of the brake oil, power pump oil, gearbox oil and antifreeze, oil is sufficient to see whether the modification, whether to a replacement cycle, the oil like a car in the blood, to the replacement cycle must be replaced to ensure the smooth circulation of oil.

In addition, for the general car owners, the brake system is the top priority of each vehicle, should always check whether weak braking, deviation, brake pedal pedaling whether the change in intensity, if necessary, clean the entire system moving parts of the system piping.

Maintenance of pipelines and fan heater

The cooler autumn weather, low temperatures occur when frost, in this season, you should pay special attention to defrost the windshield under the supply air is normal, the heat will be enough, if a problem occurs, must be promptly resolved, or else Drivers will bring insecurity. Should always check whether there is debris in these parts, if debris can be blown off with compressed air, In addition, the engine cooling state, can be washed with water guns or more parts from the inside out.

Battery Maintenance

In the fall, car battery electrode connection is that the most error-prone areas to check, if the Department has found that green oxide electrode wiring, must use water flush, which will cause the green oxide generating enough electricity to battery in the power deficit state, will cause severe battery scrap, or Dabu Zhao car phenomenon, so the main car battery especially careful inspection, do be prepared for.

Chassis maintenance

Fall maintenance chassis rust and tire inspection focused on two aspects. On the one hand, chassis metal exposure and exposure after the rain after prone to rust phenomenon, affecting driving safety. Therefore, we must deal with rust on the chassis, and check whether the chassis screws off and so on.

In addition, check the brake system should be comprehensive, its corresponding cleaning, lubrication, rust and other treatment, to ensure all aspects of normal system performance

When servicing the vehicle, accident, because not in good repair, resulting in expansion of automatic transmission glitches, deterioration caused by large accident.

But how do maintenance on the automatic models?

1. Should always check the automatic transmission oil level is normal. Automatic transmission oil check method and not the same as engine oil, engine oil in cold state inspection, gearbox oil is the oil needs to be heated to 50 ℃, then gear the gear lever to stay in 2 seconds Place the stop block, then the normal oil level oil foot should be located between the highest and lowest lines, such as not enough, the same quality in time to add the oil.

2. Master automatic transmission oil change cycle. Automatic transmission is very precise internal control mechanism, with the gap is small, so most manufacturers recommend automatic transmission drain intervals generally of two years or 4 to 6 kilometers. In the course of normal use, transmission oil temperature is generally about 120 degrees Celsius, so the high quality requirements of the oil must also be kept clean. Second, the gearbox oil to use after a long time will produce grease, sludge may be formed, will increase the friction plate and the parts wear, but also the hydraulic system so that power transfer be affected. Third, the dirty oil sludge in the valve in the valve body will move the poor, hydraulic control of the affected, so that automatic transmission abnormal.

3. The right to replace the gearbox oil. Present a better method is a dynamic oil change, oil change, gearbox with special cleaning equipment, operating in the transmission process, the full cycle of the old oil, drained and then add a new gearbox oil, so oil change rate 90 above, to ensure a good oil change effects.

Owners should take the initiative to check the training, maintenance, service awareness, you can learn some maintenance, maintenance of vehicles, the basic knowledge, read the instructions attendant, remember some of the necessary data. Scientific keep a car in order to ensure the vehicle is in good technical condition, to ensure driving safety.

    1, engine oil pressure is too low, lubrication will damage the engine, resulting in lubrication, cooling and cleaning bad, will cause the adhesive wear parts. Crankshaft main journals and connecting rod bearing clearance between journal and is too large, the oil viscosity is too low and the filter will cause low oil pressure rupture.

    2, engine oil pressure is too high, though not common, but also undermine the normal lubrication. Such as the oil viscosity is too large, metamorphic knot plastic, filter and oil duct blockage, pressure regulator improperly adjusted or not to open will cause the oil pressure is too high.

    3, excessive oil consumption, abnormal engine oil consumption and the ratio of gasoline is 0.5% -1%, if not greater than 1% of normal. In addition to the reasons for excessive oil consumption oil leakage, the more oil is burned. The main reason is: the piston and cylinder wall clearance is too large; piston ring wear off or even less elastic; valve guides wear off even; valve rod oil seal damage. Using Chi-resistant super popular engine repair agent can greatly improve piston ring sealing, repair worn internal parts, reduced oil consumption.

To solve the problem yourself is often simple and effective:

The first step to buy a can of carburetor cleaner to remove the air filter to. As the cleaning agent that can dissolve the solidified surface of the carburetor on the part of glial, with timely and easier to wash away. The current market, there are two carburetor cleaner, cheaper domestic prices, but the cleaning efficiency is low; import prices high, but the cleaning efficiency.
The second step will be to launch the engine to normal operating temperature.
The third step, hand throttle to the engine at idle and medium speed operation while under the alternative, with carburetor cleaner were facing the small nozzle carburetor idle air volume holes and the main fuel supply unit volume of air holes ( both eyes can see) Continuous spray 1-2 times 1-2 seconds, and then against the size of carburetor spray pipes a week, you can achieve the purpose of cleaning the carburetor.
The fourth step is to clean the air filter paper, filter out, to knock the dust on its surface destroyed or blown with compressed air can.

Different situations should note the following:

(1) of the carburetor and air filter cleaning work to be done according to motor cars and mileage, road conditions and determined the quality of gasoline. Proposed travel 1,000 km or every two weeks cleaning time. This will maximize the time carburetor automobile exhaust compliance.
(2) operation of the process should pay attention to safety, to prevent impurities and foreign matter fall into the carburetor. After a thorough car repair factory exhaust after treatment, can persist in the use of the carburetor and air filter regularly clean, you can reach into small (a can of carburetor cleaner can be used four times or so), and to ensure that vehicles Carburetor dirty will not result in emissions exceed.

Regularly check gearbox oil

Automatic transmission is called in the ATF into the oil, in addition to its role in lubrication of cooling, more important is to transfer power between engine and gearbox. ATF oil temperature is generally 120 degrees Celsius, so the high quality requirements of the oil must also be kept clean.

Always check the automatic transmission oil level is normal. Automatic transmission oil check method and not the same as engine oil, engine oil cooling under examination, and transmission oil is needed to oil heated to 50 ℃, then gear the gear lever to stay in 2 seconds placed in parking gear, then the normal oil level oil foot should be in between the highest and lowest lines, such as not enough, the same quality in time to add oil.

General whether the proposed manual gearbox or automatic transmission up to 12 months or 20,000 km replacement of an automatic transmission oil, and some models use the manual was written 24 months or 40,000 km replacement. But these are only general recommendations, Beijing vehicle condition as a special sand more than the weather, road congestion, poor air quality, the proposed vehicle to regular inspections and timely replacement of ATF.

Correct transmission oil change

Generally replace the automatic transmission oil is removed when the big end of the screw automatic transmission oil to miss the old oil and then add new oil, but this can only replace about 30% of the new oil, but also 70% of the old oil still remaining within the gearbox. If the purpose of breaking way sump oil change, oil change can reach 70% rate, this fact had to ensure the transmission of health. But a better method is a dynamic oil change, oil change, using a dedicated gearbox cleaning equipment, operating in the transmission process, the full cycle of the old oil, drained and then add a new gearbox oil, so oil change rate as high as 90%.

GM, Toyota, Ford and other brands of automatic transmission coefficient of friction is different so different ATF oil can not mix. Mixed ATF, will cause damage to the gearbox friction plate, there clutch, brake slipping phenomena, serious friction plate will be destroyed

■ maintenance of engine and exhaust pipe

Engine air filter is an important part throughout the car in the rain, the air filter is easy to water, especially when the road surface after water, once water, it may lead to serious mechanical troubles. Experts remind that, when found in the engine air cleaner water, and do not its engine, once launched, the water into the engine combustion chamber, and in severe scrapped the engine. Received after the vehicle engine to wipe the rain in time to check whether there are cracks generator belt, so as not to shorten the service life of vehicles. Water too deep there, they should try to detour, if you can not bypass, can be a rubber tube receiving the exhaust pipe on the top front of the nozzle, so water can not enter the exhaust pipe.

■ threats to the physical safety of high voltage ignition system

High-voltage ignition system in rainy days easy to damp, moisture will cause the ignition energy shortage, so the engine off cars, and high-voltage ignition system will produce electricity leakage after contact with water. In rainy days, if the car fails not lit, make sure not to touch the splash of water high-pressure ignition system, because at this time on high-voltage ignition system will produce instant kV high voltage, thereby threatening their personal safety.

■ Auto wandering mind

On rainy days, the brake system is also easy to water, so hysteresis brakes, causing brake car wandering the accident. Therefore rain should keep the car longer than usual distance is very important. If the brake system, water, and can be left after the rain stopped tapping on the brakes, right foot stepped on the accelerator, brake lining and brake disc by friction, water will evaporate, to ensure driving safety. While still in a timely manner after the rain tires on gravel removal, gravel, we all know, there is a tire tread water role, these things attached to the tires, the tire will have sufficient drainage capacity.

■ obscurity is not the United States

Automobile front windshield of our car when the “window”, so rain can be coated glass front windshield fog waterproof agent. Receded quickly after use can fog, rain fell rapidly, and extend the life of wiper. Sometimes the owner out of the bus after the discovery wiper bad, rainy days, rain everywhere, front windshield fog, anti-fog agent at this time will be temporarily replaced the wiper functions, can guarantee a clear front window to keep safe driving. Another mirror should pay attention to these issues.

■ eliminate injuries caused by rain

Contained in acid rain, is easy to vehicle metal corrosion. After the weather to dry the car in time of rain, or sunlight to the water drops, the drops will form condensation effect, the paint burns to cars scarred. Experts suggest that the best rain after the car open to regular vehicle maintenance shops beauty about washing and waxing, if the body had been due to rain causes a “scar”, the proposed closure can do a finishing glaze, to make your car shiny as new.

For another air filter, safety light bulbs such small living completely unnecessary on the 4S shop, light line will have to wait an hour, working hours have to catch the high fees, there was time to own Dunong finished. Therefore, the primary vehicle of knowledge like this is long overdue to look at their own tuition. Such as the brake light bulbs are consumable parts, as long as you look carefully at the car taillights simple structure, you can spend 5 dollars to buy a street lamp, and then put yourself to the car.

● maintenance to quickly repair center

Average family car to be carried out every 5,000 km driving oil, machine filter replacement, if replacement of the bottom in the 4S shop, time-consuming, laborious, but also expensive. Therefore, no technical content of this type can live safely repair shop to take care of the community soon. If you store the oil and other raw materials to provide enough confidence that you can buy a bottle of oil to the 4S shop, and then to quickly repair shops to spend 10 minutes to solve the problem. So most will pay 20 dollars of labor charges, could receive a free repair workshop on the chassis, tires and detailed inspection.

● difficult diseases to diagnose 4S shop

The cars are equipped with sophisticated electronic systems and precision mechanical components, in the case of large failure, certainly not a roadside stalls or Auto Parts City can solve. Now the 4S shop to attract more clients, fault detection is basically free, so you can run several multi-4S store look failure causes of the first test, if a few shops have the same answer is given, then the problem can be determined basically where the. But then you do not hurry to money or repair. If the repair process is not complicated, then you can buy parts from the 4S shop, and then to the city to find mechanic auto parts replacement.

● Professional needed overhaul

Cars are precision machinery, small failures can also count on those “guerrillas”, but If it encountered a larger fault, then you have to go to a professional 4S shop. That is, involving the engine, gearbox, chassis, computer and other components of the repair, be sure to select the 4S shop repair.

● do not blindly Original Accessories

Taking a moral line cars, for example, the first section of the intake air filter outside of plastic boxes in the 4S shop to 200 yuan, 80 yuan while the Auto Parts City, a vice-factory parts the street, the quality is not bad. Like plastic, even if the original Vice plants as durable, will not have to make your car broke down right away, pulls a big deal to spend 80 yuan; air filter in the plastic boxes are not part of the core body car, if there are problems not The cause permanent damage to the car; but as brake pads, tubing, belts and other key parts of these plants must not be used vice, because vice plant parts Zhiliang they are not reliable, if these key positions is a problem, it is the province of a little money can be face a significant loss of.

Even if the use of non-frequent exposure to sunlight and exposure to ozone also make wiper film aging. In use, the wiper gradually lost most of his films, elastic and flexible, it is not getting scraped clean. Because they will maintain a fixed coil state, and glass can not be well attached. This phenomenon is more likely to happen in the day lying in the open parking lot of the vehicles. Sun will bake hard rubber. When the wiper is used, they scraped stripes or have noise, because the rubber has hardened molding, can not conform to the curvature of the glass. This is very annoying and dangerous.

The cold weather also affect the life of the Wiper Blade. Cold air will make rubber hard and brittle, easy to crack. Rocker sometimes be snow and ice jamming, causing wiper can not even load film, resulting in scraping beats in the sweep of the glass, which appears corrugated.
Also make use of excessive scraping damage, dust, small particles, splashing the mud on the road or even a small bug juice will blunt the edge scraper, scrape certainly not cutting edge is not clean. As the blade shape is precisely designed to maximize the wiper effect, loss of edge, the water will drop from scraping the past, also remain in the windshield. The result is windshield wiper condition deteriorated, clear line of sight.

How to choose a good Wiper Blade

Wipers generally two types of current, a leisure break the traditional style, this is the most common wipers generally, a three-to Siduan ranging from the drivers line of sight conditions in accordance with rain and make adjustments. Another raindrop induction, more than in recent years for use in high-class vehicles, not yet popular.

How to choose a good Wiper Blade?
The first thing to your car specifications with the kind of wiper blade, can refer to the attendant manual to see if the wiper models specified above, or driving to the parts store, and asked the clerk to look at what used a kind of blade. In general, the wiper blade would be associated with metal struts for sale, seldom leaves sold separately, of course, leaves even the sting of the price will be expensive. If your confused, allowing parts store clerk to help identify.

Second, we must pay attention to strut connected to the wiper arm in the way of matches, because some of the arm is fixed to the rocker arm screws, while others are building points with convex button lock, and bought Remember when attention.
Third, the wiper pull up with your fingers after cleaning the rubber wiper-chip traces, check for damage, and how flexible rubber blade. If leaf aging, hardening, cracks, while the wiper film failed.

Fourthly, during the trial when wiper switch is in position at various speeds Department, check whether the different wiper speed to maintain a certain speed. Particularly in the intermittent mode of work, but also pay attention to whether the campaign Wiper Blade maintain a certain speed.
Fifth, check the wiper status, and whether there Wiper strut swing uneven or missing scratch phenomenon. If the following three conditions, indicating that this film failed wiper.

1, swing flow, and wipers do not normally beat.
2, rubber and glass contact surface area can not be fully fit and clean resulting residue.
3, wipe the glass surface after the water film present state of the glass produced a small stripe, fog and linear residual.
Sixth, the trial should pay attention to whether the abnormal motor noise was, particular attention is when the wiper motor, “buzzing” sound and do not rotate, indicating the mechanical transmission part of the wiper die or get stuck with rust where, when wiper switch should be closed immediately to prevent burning motor.

Seventh, the longer the wiper is not a good film. Some people would be naive to think that the longer the length of wiper blades, the greater the size of brushes, the better view? On the wrong. While extending the length of wiper blades, allows us to increase the driving in the rain View of the visible range, but it also increases the wiper motor, wiper bar burden. However, as the wiper blades and this one is easy to install DIY Parts things, owners tend not to pay attention to whether the long path length and fitted, until the brush when the results of two wipers actually fight, so of course can be extended , they do not impede the normal operation of the wiper can be.

Air-conditioning system
After a winter car air-conditioning systems in certain bacteria accumulated a lot of impurities, if this time does not wash your car air conditioning system, then use the air conditioning, interior air quality would not be so good.

Air-conditioning system is mainly cleaning air conditioning and ventilation pipe, measure the pressure and the evaporation tank cleaning. First, air conditioning and ventilation pipe cleaning sterilization, it is a must air out of the wind, dust in the ventilation pipe wall and a large number of bacteria which swept into the car with air conditioning and ventilation, so cleaning and sterilization is very important. Secondly, the pressure system of detection, mainly to check the adequacy of the refrigerant, or whether disclosure. Finally, cleaning the dust evaporation tank.

Engine testing
Engine but the car’s “heart”, if the heart problem is a big problem that can be, so the engine test is also very important. First, change the oil, if your car is the seasonal oil, then you can see the need to fill, if it is winter and summer would change at this time, a summer oil. Various oil and liquids also need to detect and fill to see if there is no leakage of antifreeze, brake fluid and power steering oil is not a need to fill. In addition, the engine cleaning is the most important because after the winter, near the nozzle produces a lot of coke, if not promptly cleaned, they would not produce sufficient fuel injection nozzle, resulting in less motivated to make a substantial increase in fuel consumption.

Chassis inspection
51 Zijia You of course, would have varying degrees of damage caused by the chassis, the chassis so that detection is quite necessary. Main steering rod chassis testing, the arm ball top. The chassis, chassis testing is mainly to see whether there are scratches, as scratches can cause fetal deformation and the phenomenon of eating, it will lead to a series of safety problems, such as “deviation.” In addition, the tire wear is part of a larger one, Zijia You come back, it must be done about the tire test to see if there is loss of air or the abrasions invisible class of problems, to go to a professional auto repair Office fully check the tire pressure, balance, and whether there is an aging four-wheel cracks or trauma, and severe tire wear should be replaced promptly.

Body Interior
The arrival of summer, people need not only sun, car sun also need. While not particularly hot day when the car gave the closure of the glaze and coating is the best as this. Closed car paint enamel can extend the life of slow fading, old enamel sealing effect is more obvious, make faded paint oxidation reduction by Yan. After the glazing seal the biggest advantage is the vehicles anti-ultraviolet radiation, anti-acid erosion, prevention of sand in the Army, to protect the paint is not fading caused by oxidation, can also fire anti-glazed oil and mild scratch hard objects rub.

Next is the interior, carpet to look clean at this time, because it mixed with a lot of dust inside, in a timely manner will improve the interior air quality clean, give you a clean and refreshing summer.
