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.
