Automotive air filter and oil maintenance of common sense

Air filters, oil filters and fuel filter is what we call the car "three filter", their role is filtered into any liquid and gas inside the car engine, the protective effects of engine, while it can also improve the efficiency of the engine, you can use the OBD Diagnostic Tool to detect engine efficiency. Now, it says the main air filter and oil filter replacement and maintenance points.

Air Filter
The main action of the air filter is used to filter impurities in the air, provide clean gas engine, in this process, impurities in the air are adsorbed on the surface of the air filter reach a certain mileage, it will form a black look, this time the filter effect has been very poor, and must be replaced in time, you need Launch X431 IV GX4 Master or Launch X431 Diagun III tools.

In addition, when you find the car underpowered and engine sounds abnormal sound, cost of oil, air filter should be replaced, if the cars used dirty air filter, the engine will enter the gas shortage, so that the fuel combustion completely, causing the engine work instability, power down, increasing fuel consumption occurs, you can use the Launch Diagnostic Tool to detect. Therefore, the car must be kept clean air filter.

Oil Filter
The internal combustion engine use, dust, metal wear, clean carbon and other mechanical impurities will continue to mix the oil, while the combustion air and exhaust gas oxidation of the oil on oil will also gradually produce gum. After using to a certain time, use Autel Maxidiag Elite MD701 or Autel MaxiDiag Elite MD802 tools to detect, machine filter surface will be attached to a lot of dirt, if from time to time to replace the oil filter there will be blockage consequences.

Automotive Air Conditioning abnormal sound failure analysis

Air conditioning start after the main noise is the working compressor noise, it does not belong to a malfunction. Because the operation of the compressor is intermittent, not always in working condition, when it will start again Loud noise at work, the majority of cases are failures blower control module, the use of Auto Diagnostic Tool checks out, the need for timely replacement the new accessories.

Summer fast approaching, air conditioning has become the owner of the car entered the car primary action. However, while owners enjoy the cool, often feel malaise, these symptoms are typical of the car, "Air conditioning disease." The need for timely use Launch X431 V+ Pro3 tool or Launch X431 V Pro to check, to prevent the effects of health.

Three kinds of methods to solve the problem of car horn

The horn is a frequent use of the device while driving, if the speaker fails, it will be very difficult when driving. Sometimes honked the horn, the sound is very hoarse, and even a little voice at all. We need to use the Auto Diagnostic Tool timely detection, we take a look at how the horn works. When the horn button is pressed, the battery current will flow through the loop on the horn relay solenoid, solenoid relay attract dynamic contact switch is closed, current will flow to the speaker place. Electromagnet current work inside the horn, so that the diaphragm vibration sound.

According to the author's experience, many faults related to the speaker, problems arise fault is often the horn itself . Especially flawed speaker installation location of some design, when it rains very easy make the speaker wet in the rain, causing damage to the speaker. When the speaker does not ring, common failure parts are nothing more than 3 points, that horn itself, horn switch contacts and horn line, when a fault occurs can be used Launch X431 GDS or Launch X431 IV GX4 tool to check the following steps:

(1) sometimes does not ring. Press horn switch, if the horn is sometimes loud, sometimes does not ring, mostly inside the horn switch contact contacts well, some of them are horn itself.

(2) voice hoarse. Mostly due to poor contact plugs, especially the various contacts around the steering wheel, as a result of frequent use, easy to make contacts to wear.

(3)Completely does not ring. First check to see if the fuse is blown, then unplug the speaker plug, use Autel MaxiSys Pro MS908P or Autel Maxidiag Elite MD702 tools to detect whether horn switch is electricity. If there is no power, check the horn and horn relay harness; if there is electricity, it is the speaker itself is the problem, then you can try to adjust the adjusting nut on the horn to see if sound, if still does not ring, you need to replace the speaker.

How to prevent car spontaneous combustion

In summer, the car ignition incidents continue to occur, in fact, the majority of vehicles spontaneous combustion are to be expected. Automotive body noise, a coke burnt taste, smoke is likely to be the precursor of spontaneous combustion. In case of spontaneous combustion, the car personnel should immediately leave the car, you can use the OBD Diagnostic Tool to detect vehicle performance, professional advice, occur in hot weather, the owner of car maintenance should pay attention to the following points:

First, check the oil. We usually find that a lot of cars have symptoms of chassis oil spill , in the hot season, which is likely to be the cause of spontaneous combustion. And the spontaneous combustion accident at ordinary times is also for oil. Hence the need for frequent use Launch X431 V Pro or Launch X431 Creader VIII tool to view the car, if the engine oil spills, oil spills chassis tubing signs of aging or broken it should go to a professional repair shop or 4S shop maintenance.

Second, check the circuit. More than three years of car especially modified car headlights, modified car stereo should be comprehensive examination. Car circuit fire occupy a considerable proportion of spontaneous combustion events. Engine, ignition coil, high temperature, high voltage ignition wire insulation softening, aging, dehiscence, high-voltage ignition easy breakdown of the insulating layer, it is easy to produce high-voltage leakage, leading to spontaneous combustion.

Third, after the car stopped immediately shut down the engine , to develop good driving habits. The hot season, the ground temperature is higher, when parked idling and others, the maximum temperature of the exhaust pipe under the car, even higher than 800 ℃. If there is a parking ground hay, paint, or other flammable items, for a long time under the baking will be on fire, and burn the car.

Fourth, Clean up the car of inflammable and explosive materials. The male driver of friends like lighters on the center console, in the hot season, this habit will become very dangerous. Another perfume contains more alcohol, and very easy to fire. Now a lot of automotive interior materials generally do not have fire resistance in case of fire, the fire spread easily.

Summer is the high incidence of car ignition, the car ignition, generally due to a short circuit electrical wiring or inside the vehicle flammable materials. To avoid spontaneous combustion to reduce the chance of your car, regular maintenance regularly, but every car with at least one Autel MaxiTPMS TS601 or Autel MaxiTPMS TS401 tools, check the car function.

15 minutes to quickly remove the odor of automotive air conditioning

Automotive air conditioning after a very long time without use, open feel the smell blowing. Especially those moldy smell, so the driver feel uncomfortable. Some of driver go to 4S shop for cleaning the entire air conditioning system, duct. In fact, there are three kinds of effective methods of air conditioning in addition to smell, it is worth a try. Some methods require Auto Diagnostic Tool, you may wish to look at their own personal experience.

1. Replace the evaporator equipment, and manual cleaning air conditioning heating device at the bottom of the shell;

2. Clean the evaporator, to the air conditioning and heating device sprayed disinfectant on the bottom of the shell, eliminate the inside mold;

3. The first two approaches is slightly complicated, the third method is simpler, you can open the air-conditioning heat windshield maximum temperature, continuous opening 15 minutes, it will effectively remove the musty, mildew and odors.

Can go to the market to buy supplies automotive air conditioning cleaning agent or sterilization deodorant spray. Then, open the windows, start the engine, then closed the air conditioner AC block, open to the outer loop block, then the fan to maximum. In this case, find the external air inlet port of the vehicle, which is injected into the cleaning agents, cleaning agents on the wind, attached to the surface of the evaporator and evaporator will absorb dust and mold, then let the fan run another 15 minutes. Next, the cleaning agent will be discharged from the drain outside the vehicle, the whole operation takes about half an hour, then use Launch X431 Diagun III or Launch X431 PAD tool for detection.

Three methods of self testing whether the car burning oil

Generally have the phenomenon of burning oil vehicle exhaust will have different degree of "blue smoke" symptoms, oil consumption increased significantly, a short period of time will have to add oil. Vehicles burning oil, it will lead to increased coke combustion chamber, economy cars, power drop, excessive exhaust emissions and other adverse consequences. Automotive expert introduces three methods of self testing whether the car burning oil, need to use the OBD Diagnostic Tool to detect, is simple and effective, may wish to try.

The first method is: when driving in the morning, the exhaust pipe appeared darker blue smoke, blue smoke disappear after a while, that day may not happen again, but the next day, the third day morning appeared This phenomenon, which shows that the vehicle has appeared the phenomenon of burning oil.

The second method is: When the vehicle is traveling,The driver stepped on the accelerator when the forced exhaust a lot of blue smoke, which shows a vehicle burning oil phenomenon has been more serious.

The third method is: In addition to the exhaust pipe to take blue smoke, you can see the blue smoke from the oil out mouth pulsation. In this case, engine damage has been very serious.

Once a car burning oil phenomenon occurs, it is necessary to go to 4S shop use the Launch X431 V+ Pro3 or Launch X431 GDS tools to detect and repair.

The poor sealing of the cylinder is mainly caused by the burning oil. Mainly with the gap between the piston and the cylinder wall is too large, the piston ring seal improperly installed or worse, oil on the cylinder wall into the combustion chamber, causing the phenomenon of burning oil.

Auto repair experts said, causing the vehicle to burn the oil with the driver's driving habits. the driver to develop good driving habits, while possible, choose a good quality oil, the appropriate use of a slightly larger engine oil viscosity to increase piston seal between the cylinder wall,; ground check the dipstick regularly change the oil and oil filter, Genuine spare parts to replace the oil filter; timely use Autel MaxiSys Mini MS905 or Autel MaxiDiag Elite MD802 tools to detect vehicle performance, can effectively avoid the phenomenon of burning oil.

How to DIY maintenance car battery

Battery plays an important role in the use of car, if it can not normal work, car will not start running, while the car's power consumption in winter than in other seasons is much greater, and the battery is also afraid of low temperature, low temperature battery electrical capacitance is much lower than the normal temperature. So for battery maintenance is quite necessary. Battery life of about two years, you can also use Auto Diagnostic Tool to detect battery performance. Battery maintenance is not complicated, they can do it.

The first step, With a damp cloth to scrub the battery outside, the panel, on the stigma (ie, both positive and negative poles) of dirt, oil, white powder and so easy to cause the leakage of dirt to wipe clean, and use special grease to protect trailer coupling, to prevent corrosion.

The second step is to check the battery electrolyte leakage or deformation phenomenon. Some models are equipped with all maintenance-free battery, relevant or labels, do not disassemble the battery for this, if there is leakage, deformation of the phenomenon, it is best to go to the repair shop to solve. The battery life of about two years, should be used Launch X431 IV GX4 Master or Launch X431 V Pro tools to check the battery performance, timely replacement if necessary.

The third step, if the car park a few weeks, should be remove the batteries, stored in a warmer room, to prevent freezing damage to the rear battery self-discharge. When the ambient temperature is below minus 10 degrees, fully discharged battery will freeze, must thaw the frozen processed before charging the battery, if directly charging may cause an explosion.

So, in fact, battery maintenance is not difficult, you use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect, do regular maintenance on their car, extending its working life.

Haze days increased air filter needs to be replaced twice

A wider range of haze invasion world, more and more people are used to go out wearing masks, but also car also need to "mask" - air conditioner filter to reduce vehicle particulate matter concentrations. Usually owners are in the maintenance replacement air filter, but with the increase in fog and haze and dust, recommended replacement air filter regularly, best replacement filter twice a year. If you don't know when to replace, you can use the OBD diagnostic tool detection.

Test results show that if there is no air conditioning filter, the concentration of the driver inhaled pollutants is much higher than the pedestrian path, like a vacuum cleaner, as the car's ventilation system inhalation of contaminated air contains particles and harmful gases, and every hours up to 420,000 liters of air through the filter, air conditioning, heating systems and bellows into the interior of the vehicle. Filter R & D personnel, over time, the filter core - will gradually clog the filter media, bellows capacity will be reduced by 50% to 70%. In order to ensure full and effective air filtration and good ventilation, air filters should be timely, regular replacement, you can use the Launch X431 PAD or Launch X431 Diagun III tool testing. Therefore, for long-distance drivers or often drive, the regular replacement of the filter is necessary.

Four misunderstanding to use lubricating oil

Automobile lubricating oil used in maintenance frequency is very high. In addition to high-quality lubricants to protect the engine, reducing the number of oil changes, but also save gasoline. At the same time, should also be careful not to because of lubricating oil caused by improper use of auto fault, you can use the OBD diagnostic tools to detect the car's performance, there are four main "misunderstanding".

First misunderstanding: Lubricating oil, the more the better
Lubricating oil amount should be controlled between oil ruler, between the lower scale line as well. Because too much oil from the gap between the piston and cylinder in fleeing into the combustion chamber to form coke. These carbon will improve the compression ratio of the engine, increase the tendency to produce knock; coke formation in the cylinder are red state but also easy to cause the premature combustion, such as falling into the cylinder will aggravate the wear of cylinder and piston, will accelerate oil pollution. Secondly, the lubricating oil excessive stirring resistance of crankshaft connecting rod, increase fuel consumption.

Second misconceptions: Lubricants black, oil change at once
This understanding is not comprehensive. For there is no oil plus dispersant quiet, the color black is indeed a serious deterioration of the performance of the oil already, but the use of modern automotive lubricants are generally added quiet decomposers. This quiet film adhesion agent and black carbon deposition on the piston wash down and dispersed in oil, reduce sediment generation engine temperature, so the use of lubricants colors tend to darken after a period of time, but this time Oil is not completely bad, you can use the Launch X-431 PAD or Launch X431 V Pro tools to detect.

Third misconceptions: Lubricating oil is often added, not replace
Always check the lubricant is correct, but only supplement not replace the oil can only compensate for the lack of quantity, but can not fully compensate for the loss of lubricating properties. Lubricating oil during use, due to contamination, oxidation and other reasons quality will gradually decrease, while there will be some consumption, so that reduction in the number.

Fourth misconceptions: Additives
Really high quality lubricating oil is with multiple engine protection function of the finished product, the formula already contains a variety of additives, including anti-wear agents, lubricants and most exquisite balance formula to protect the various properties of the full play. Add the other additives can not give the vehicle to bring additional protection, but is easy to react with the chemicals in the oil, causing the oil decline overall performance, you can use the Autel MaxiSys Pro MS908P or Autel MaxiTPMS TS401 tool to detect auto comprehensive performance.

How to maintain the automobile engine cooling system

Cooling system work after a certain time, internal can form all kinds of dirt . For large departmental vehicles, usually water, use antifreeze only in winter low temperature conditions, this case is easy to cause the rust and dirt; a vehicle for long-term use of antifreeze can cause security problems, You need timely use OBD diagnostic tools to detect and avoid accidents.

Automotive Engine Cooling Maintenance
1, the correct selection of cooling water, but also to the selection of high quality products. If you use a low-quality product, the same may be tank corrosion system components, causing the tank leaks, pipes get clogged, rapid warming and other conditions, and ultimately lead to vehicle breakdown or accident.

2, tank cleaning and washing, regular use of cleaning agents to clean the tank and use the Launch X431 V+ Pro3 or Launch X431 Diagun III tools to detect, remove rust and scale, not only to ensure that the engine is working properly, and to extend the overall life of the tank and the engine.

Tank cleaning agent function
Engine cooling system, the water and glycol-based coolant can easily form an acidic substance, corrosion, damage radiators and other metal parts. in addition to appear in the cooling system scale, corrosion, cavitation and harmful ionization reaction will greatly reduce the cooling capacity, shorten the life of the tank or even the entire system. The high quality of the water tank protective agent can effectively protect the cooling system, inhibit scale, corrosion and acids generated prevent harmful ionizing react to improve the cooling effect, you can use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect, prevent engine overheating fault.

Automotive filter maintenance guide

Automotive filter is a device used to filter impurities. In the car the main air filters, oil filters and fuel filters, known as the "three filter." Filters used to filter impurities, filter has a great influence on the main effect of other components, in use, must be regularly use Auto Diagnostic Tool maintenance and replacement.

First, the air filter
Car engines are very sophisticated parts, tiny impurities will damage the engine. Therefore, the air before entering the cylinder, must first go through the air filter cleaner, in order to enter the cylinder. The air filter has relations with the life of the engine.

Currently, the car engine is used widely in the filter paper, it has a low mass, low cost, easy to replace, high efficiency filtration, general cleaning once traveling 5000 kilometers. Clean the filter should be removed gently tapping the end face, use compressed air to blow from inside to outside , do not wash with gasoline or water. Traveling 25,000 kilometers must replace the air filter.

Second, the oil filter
Most car engines using spin-on oil filter, this filter is not disposable filter unpick and wash, when changing the oil must replace the oil filter, otherwise it will affect the oil quality. Replace the oil and oil filter cycle, generally is 5000 km. Pay particular attention when changing the oil filter, but also pay attention to the choice of oil, you can use Launch X431 GDS or Launch X431 V Pro tools to detect engine performance.

Third, the fuel filter
At present, most of the engine is a one-time non-washable jacket-style paper filter, fuel filter replacement cycle is generally 10,000 km. When replacing the filter, the filter has to pay attention to the arrow mark, in the replacement, do not installed anti. Recommend the replacement cycle of fuel filter should be according to its structure, properties and USES of varies.

Most car manufacturers on the external filter recommended normal maintenance and replacement cycle for 50000 km. If you are unsure, please use Autel MaxiSys Pro MS908P or Autel MaxiTPMS TS501 tool to view. In addition, when the filter hose appears the dust, oil and other dirt, causing the hose aging or cracks, the need for timely replacement hose.

Summer car air conditioning maintenance tips

Summer use car, certainly can not do without air conditioning. Then the use of car air-conditioning, the owners should pay attention to what? Today we'll explore the automotive air conditioning problem, of course, also need to prepare OBD diagnostic tool.

Clean the condenser
Air-conditioning system in use for some time, the surface of the condenser will be coated with some foreign body, these foreign bodies blocking the air filter, or floating on the surface of the condenser, which will affect the cooling effect of air conditioning, air conditioning will produce odor, adverse effects on the human body . Should go to the auto repair shop for an inspection of the vehicle air conditioning system, generally they will use Launch X431 IV GX4 Master or Launch X-431 PAD tool to clean the condenser surface of the foreign body, if necessary replace the air filter, in order to maintain a good environment for air conditioning running.

Lack of refrigerant
Lack of air conditioning refrigerant is the main cause of air conditioning refrigeration effect is not good. In normal circumstances, the refrigerant is not reduced, and the main reason is the refrigerant that leaked. Therefore, when check the air conditioning system, to each line carefully check joint, found to have leaked refrigerant situation due to the timely change of relevant components. May require the repair shop at the same time add refrigerant added significantly colored dye, so that when you can easily found leak and timely treatment.

Sterilization
Air conditioning system has numerous piping, duct, these ducts in daily use due to temperature changes, moisture will produce internal hard to avoid. In addition, as the microbes in the air will be left in the air conditioning duct. It's all fueled the growth of bacteria, the bacteria will breed conditioning system odors, serious harm to the health of vehicle occupants. Therefore, regular air-conditioning system for disinfection is still necessary.

Air conditioning additives
The air conditioning compressor additives can increase the compressor, reduce noise, reduce friction, and air conditioning work together to improve the efficiency and extend the life of air conditioning effect. In the auto supply store to buy air conditioning system additive package, the owner can own maintenance on the air conditioning system, the main tool is Autel Maxidiag Elite MD701 or Autel Maxidiag Elite MD703. The main effect of conditioning additives are:

1. Can improve the cooling effect, low air temperature 2-5 ℃.
2. Reduce friction compressor and prolong life.
3. Reduce the air conditioning compressor noise.
4. The fuel savings of about 10%.

Car window untight seal failure and solving methods

In the car window glass damage, want to change with the same original window glass, at the same time to check the glass guide groove and seal has no damage. Because of the window after repair is often difficult to return to its original shape, therefore, when in addition to ensure easy pulling or lifting window glass, but also pay attention to the window glass in the windows closed after around of tightness, you need Auto tools to detect.

When changing the car roof, the roof should be applied at the periphery lamination layer of conductive sealant, well then be welded seams in the water tank and fold over the painted plastic, which will not only contribute to the body of the seal, but also can prevent the body for flanging seam water, you need Launch X431 GDS or Launch X431 Diagun III tools to detect.

Produced early rust. When you want to assemble the door panel in the door window to paste an entire sealed off following the film, if not forming a seal barrier film, you can use plain paper instead of plastic, and then affix the seal spacer film compaction, and finally carried out interior panels production assembly.

When repairing a door seal flange, the flange should be noted that repair damaged seal, to accurately restore the original shape of the flange. After repairing the door to be tightness check, check method is: put a piece of cardboard in a sealed position, close the door, and then pull the paper, based on the size of the rally to determine whether a good seal. If the force required to pull the paper too much explanation sealed tight, it will affect the normal shut the door, and may also make the seal due to excessive deformation surface quickly lost in the sealing performance; if the force required to pull the paper too small, that seal bad, often can appear the phenomenon of the rain. In the replacement of the door must pay attention to apply in the inner and outer plate flanging occlusal hemming adhesive for car door, and some left in the stamping process of small hole with the base tape block.

Repairing the car line, should be all body hole, hole in the sealing ring is arranged in the wire harness, because they not only act as a seal ring, but also play a role in the protection harness. If the seal is damaged or harness can rotate or ran in the ring, you should replace the seals, and compare it with the body hole, hole assembly firm, stable good harness. you can use Autel MaxiDas DS708 or Autel MaxiSys Pro MS908P tools to detect.

When replacing the entire body, except for the above projects should be completed, but also on the lap portion of the weld joints are coated with a layer of sealant layer thickness should be about 1mm, and may not have a virtual sticky glue , bubbles and other defects; at the hem hem should be coated with special glue; in the entire floor surface should be coated elastomeric coating and anti-corrosion coating 3mm-4mm lower surface and the front cover; to paste the sound and heat insulation, vibration damping plate surface and the surface of the film in the floor, and then covered with insulation block, finally put on a carpet or a decorative floor. The corrosion rate of these measures can not only greatly enhance the vehicle sealing and slow down the body, but also can greatly improve the ride comfort.

Automobile brake system five common sense

The brake system is the guarantee of a car can at any time according to the driver's intention to slow down or even stop system, brake system is very important so that you can use the OBD diagnostic tool to check to ensure that the brake system to work properly. Look for Car Brake System 5 tips:

1, ABS warning light in the instrument lights up, please as soon as possible to the 4S shop inspection and handling, to avoid affecting traffic safety and travel delays. If you have Launch X431 IV GX4 Master or Launch X431 Diagun III diagnostic tool, you can check your car's problem, no need to 4S repair shop.

2, Loosen the brake after start, heard a friction brake pads and brake discs, this is normal phenomenon.

After starting the engine, the driver will be put on the brakes to shift after operation, loosen the brake vehicles running start, after gear hangs in the brake pads and brake discs have been carried out under normal temperature conditions, but did not produce great friction, vehicle gear will produce forward or backward driving force, this time release the brake pedal, the brake pad and the brake disc will produce sound. If the brake disc at the car wash water this voice will be more obvious.

3. The parking brake cable growth after a period of time: This is normal. Handbrake cable is composed of multiple sets of wires, the force after a certain ductility, in use for some time, it will have a certain elongation than the length of new car, and will not have any impact on the parking brake .

4, Brake disc rusty: the brake disc main component is iron, the vehicle is not used for a long time, the disk surface will have some rust, but the vehicle is in motion through the work of the braking system, would eliminate rust, does not affect the normal use.

5, The brake disc after the use of fever: a normal phenomenon. Brake is by friction brake pads and brake discs to achieve, is the kinetic energy is converted into heat energy in the process, it will generate heat. Keep your hands after touching the parking brake discs, to avoid burns. If you're still worried, you can use Autel MaxiDas DS708 or Autel MaxiScan VAG405 tool checks to ensure road safety.

Fuel filter basic maintenance of common sense

Fuel filter replacement cycle
Fuel filter replacement is recommended once every 10,000 kilometers, built-tank fuel filter replacement 4W - 8W km. The differences between different models of the maintenance cycle may be slightly, your car when need to replace the maintenance, please via OBD diagnostic tool understand.

To conduct a comprehensive maintenance, fuel filter and oil filter, air filter, machine commonly replaced at the same time. Disassembly to replace the fuel filter is more complex, not easily do it yourself, you need go to repair shop and let professionals to operate install.

The necessity of replacing the fuel filter
Fuel filter according to the different filter can be divided into gasoline fuel filter and diesel fuel filter, home cars use a fuel filter, fuel filter are divided into built-in and external tank.

The vehicle with the use of the growth of the age, with increased mileage and fuel filter long-term work, to reach a certain life cycle, will cause the car to accelerate weakness, increased fuel consumption, noise increase, reduce handling performance, you can also use the Launch X431 GDS or Launch X431 V Pro check the fuel filter performance.

Fuel filter purchase considerations
1, before the purchase of goods, be sure to verify the car's model, displacement and other information to ensure that the correct types of accessories available. You can check the maintenance manual.

2, high quality fuel filter, poor-quality fuel filter often leads to oil poor, lack of motivation or even turn off the car. No filter impurities, a long time, oil and fuel injection systems may cause corrosion damage.

How to maintenance long term parked cars

Due to business reasons will be long term parked car, In the purchase of second new car and put old car park over a long period of time, this approach is very bad for the car, it is prone to accidents, you can use Auto diagnostic tool to check vehicle safety performance, ensure that no problem, you can use the car to travel.

Long term not use of car failure rate is higher than the normal use of the car. Parked car more than a week, it will shorten the life of vehicles. If the vehicle long home garage for too long, the proposed re-use, timely use of Launch X431 IV GX4 Master or Launch X431 Diagun III tool checked batteries, oil, etc.

Vehicle is in motion, the engine will charge the battery, if long-term not use, the battery is not charging, still give the anti-theft devices and other electronic equipment supply, over time there will be loss of electricity, causing the vehicle can not be normal. If the battery power loss occurs frequently, the battery life will be greatly reduced. For some of the battery storage capacity had been declining and vehicle park more than a week, are likely to lead to the vehicle can not be the ignition phenomenon.

Long-term parking the car will cause engine oil, brake fluid, antifreeze and other deterioration. Seal will be relatively easy to aging, because the vehicle to stop at the contact force is always uneven seal around until the seal permanent deformation, so very easy to spill. If the tire pressure is too low or the park, such as a bad environment, but also lead to corrosion or rim tire deformation. So, after long-term parking, it is recommended vehicle to the repair shop to check all kinds of oil, after long-term parking of vehicles, it is recommended to shorten the maintenance cycle, check should also include a variety of circuits, wires, etc. beware of rats and other biting. Electronic component failure. Electronic components and connectors on the car have a common characteristic, is to water, moisture and corrosion, otherwise it will lead to failure. For suspended vehicle electronic components or plug wire connector, it will greatly increase the likelihood of damp, and suspended longer, the probability of failure is higher.

Long term parking, tire deformation. The car stopped, the weight of the car is composed of 4 parts of the tire contact with the ground contact pressure bearing, resulting in shrinkage deformation. The longer the time cars off the road, the more difficult parts of the deformation recovery, so that the weight of the tire around the distribution changes, uneven rolling radius, causing tire imbalance. Once the car into the high-speed, the body will occur chattering can be accelerated wear of tires, but also bring the problem of traffic safety. So when re-use of the car, you need to use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 diagnostic tool to detect and avoid accidents.

According to the temperature replace oil

Most of the car owners are maintenance according to their car driving mileage, for some owners, if not achieve the required mileage and also maintenance, but also need to use the OBD diagnostic tools for vehicle maintenance, especially the temperature low special attention to.

Some people may ask, why did not achieve mileage also need to do maintenance. This is one of the main secret lies in the oil. Maybe the maintenance on the car we usually do not notice, regardless of what kind of brand of oil drums on top will have some numbers. For example 5W / 40,0W / 30,10W / 30 and so on. In fact, these labels and seasonal changes have a direct relationship.

W represents a numeral of Winter (Winter) Abbreviation, digital W before the smaller, the smaller the low-temperature viscosity, the better the low temperature fluidity, the lower most suitable temperature. And behind the figures in general are: 20,30,40,50, the larger the number the greater the viscosity.

5W oil winter low temperature can reach minus 30 degrees Celsius, the degree of resistance to low temperature oil 0W label can reach minus 40 degrees Celsius, these two labels to meet the basic situation in most parts of hypothermia. But some of China's northeastern extreme cold areas, hypothermia usually can reach minus 30 degrees or lower. If the last oil change labels for 5W or 10W oil then we would re-replacement, or cause severe wear in winter oil illiquid car's engine will shorten life. If you do not know when to change the oil, you can use the Launch Diagnostic Tool OR Autel Diagnostic Tool, to help you diagnose any problems with the car.

How to prevent car carbon deposition

Automotive carbon has been the most troublesome aspects of maintenance car, but if the daily driving process if pay attention to good driving habits, regular use of Auto Diagnostic Tool, can greatly reduce the formation of automobile carbon. Here are some basic tips.

1, Don't long time idle running
Idle time is long, the engine at normal temperature time is longer, the gasoline spray valve on the back of the evaporation speed is slow, the carbon deposition which. At the same time often idle speed, the air flow into the engine is small, so that the carbon flushing action is also very weak, will promote the accumulation of carbon deposition.

2, Pay attention to flame the timing
For cars equipped with a turbocharger, after climbing at high speeds or do not immediately turn off at idle for 10 minutes and then turn off, the car is equipped with a turbocharger speed the formation of coke than the naturally aspirated type of car to be several times faster.

That car is satisfied in the routine maintenance conditions every 20000 to 40000 kilometers to do cleaning air intake system, which is under the premise without disassembly of the engine, with the Launch X431 Diagun III or Launch X-431 PAD dedicated device-specific method for the vehicle inlet, valves, oil and so easy to the formation of the carbon parts cleaning operation.

3, The use of clean gasoline
Gasoline is the main component in the formation of carbon impurities, so the trend of high gasoline cleanliness formation of coke on the weaker. But beware of high-grade does not mean high quality, label represent octane oil, and do not represent the quality and cleanliness. Some owners in order to ensure the cleanliness of gasoline will be used in practice to add gasoline gasoline detergent. This effectively prevents the metal layer is formed on the surface of carbon knot, and can gradually activated carbon particles existing and slowly removed, can also use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool checks, in order to protect the engine from damage.
