Rainy day road safety matters needing attention

Check the car before departure
First check wiper. The best is to put every gear wiper try them and see if it is working properly; Also, pay attention to the wiper blade wiper usually used in negative net, if not clean, then we must be replaced. If the wiper failure because of driving rain, it is prone to accidents.

Moreover, the kind of severe tire wear is hidden driving rain, so the tires before driving to note whether there is normal wear and tear.

How to remove the mist produced by the process of moving the car windshield?
The most common method is to turn on the air. This is because the cool air is blown onto the glass, a "cold film" is formed on the surface of the glass to prevent carbon dioxide condensed on the glass, play a defogging effect. You can also buy the auto parts store or fogging dehazers towels. Defogging agent is sprayed onto the glass surface within an automobile, and wipe clean, clear glass in the dirt while also forming a thin transparent protective film on a glass, to prevent the water vapor mist is formed on the glass layer condensation.

What to pay attention to when it rains stop?
First of all, do not stop the rain, air conditioning. In rainy days, when the low-speed parking, gasoline by water vapor, temperature, engine speed and other effects are not able to fully burn. When the car is stopped but the air conditioning did remain open, but the car is still in the closed state of the doors and windows, interior air convection can not, if the engine exhaust carbon monoxide leaking into the car, and it will gradually build up concentration, leading to poisoning and even death of adverse consequences. Secondly, do not stop at stop unsafe in high winds, heavy rain location trees, billboards, telephone poles, walls, etc. Do not stop at the low-lying area, such as tunnel hole, pothole zone, downhill, under the overpass, etc., so the car was flooded.

After driving the car in the rain should be how to care?
First, the car dehumidification. Should open the cold when it rains, it can not only remove the mist, as well as dehumidification function. The rain stopped even have to pay attention, to get rid of as soon as possible the accumulation of moisture, or prone to mildew and other conditions.

Second, the car sterilization. Rain as temperatures and other factors, relatively easy to breed a variety of bacteria, so the interior space disinfection sterilization is particularly important. Focus on clean corners everywhere.

Third, the conservation of the chassis. Owners can conduct a "sealed plastic chassis", which enables chassis and isolated, to corrosion, rust, noise function, can effectively extend the life of the body.

Fourth, check the brake. Because of the braking system has a very strong adhesive force, rain is very easy to enter the brake fluid, it will affect the braking effect, may cause serious Zhidongshiling. For the treatment of this condition, the rain to a professional auto repair shop on the brake system checked.

Some auto diagnostic tools will help you test out your vehicle on your own, for example: Launch X431 IV, Launch X431 Pro3, Autel MaxiSys MS908, Autel MaxiDas DS708 and so on.

How to detect engine oil quality

Most auto repair shops tell the owner, should you replace a 5000 km oil. But what you have not studied the owners really have to replace 5000 kilometers of oil? Or is 5000 km replace the oil was already too late? This article will show you a simple and feasible, affordable oil quality testing methods.

Slow qualitative dipstick:

This paper used for ion determination and chemical composition, it can be determined whether the sample contains a certain amount of a substance. Some of the material strip can be measured non-destructively measured.

We use this strip will be able to detect the oil inside the oil contained in the measurement status of the different components, to determine whether the oil has deteriorated.

Remove the dipstick, qualitative dipstick in the slow drip drop of oil on the dipstick, the paper horizontally, wait 24 hours.

If used oil droplets carry out such operations in the paper, we will find that after 24 hours standing (Note: the back of the paper, please vacant, so as not to affect the test results strapped cup is a good way), will appear on the paper mentioned below three important to the annular region.

1. deposited in the center of the ring spots coarse impurities within the oil deposits centralized place, the extent of the deposition ring can roughly determine the color depth of oil contamination.

2. diffuser ring in the periphery of the deposition ring ring ring band called diffusion, which is suspended fine particles in the oil spreads out the traces of impurities. The more fine particles, diffusion farther. Diffusion width and color uniformity ring is an important factor, which represents the additive dispersing ability of contaminants within the oil.

3. Oil ring at the periphery of the oil ring diffuser ring, color from light yellow to reddish brown, indicating the degree of oxidation of the oil.

Said the four grades of oil quality:

One: no clear boundaries between the deposition zone oil spots and diffusion regions, uniform color throughout the oil patch, oil ring light and bright, good quality oil.

Two: the deposition ring color depth, wide proliferation ring, with a clear dividing line, the oil ring is yellow at different depths, oil contaminated, oil can still be used.

Three: dark ring deposition, sediment density, diffusion ring narrow, darker oil ring, oil has deteriorated.

Four: only the center ring and oil ring deposition, no proliferation ring, ring black sediments deposited thick dense and thick, easy to dry, oil ring into the yellow and light brown, oily already oxidative deterioration.

Test Results: When the three reached the spot test would need to be replaced. In general, car oil is difficult in such a situation three levels, such as the situation arise, said three of the oil quality has deteriorated severely, recommended that owners in the deposition and diffusion ring ring color is darker with the proliferation ring has narrowing the time to replace oil. This can better cost savings, but also help extend engine life.

Regular car oil were detected, one can determine a reasonable time to change the oil, but also to avoid the premature replacement of oil brought lubricant waste. For the analysis of the oil anomalies can be detected early and eliminate the presence of engine failure risks, improve the reliability and service life of the engine.

Automobile driving at night how to correctly use the lights

Predict the primary road lights
To be able to increase road capacity, the town has generated many of the primary streets from the road. In visiting the primary streets in to the evening, while exports to look at if the lights and also at the entrances. Since the transport sector designed inlet and outlet direction using the almighty, there's a particular streets direction position, normal automobiles can’t direct the sunshine only into and from the primary, side streets can direct light automobiles found in other automobiles.

No fence reduce speed
Many mixed lane no center guardrail, the situation for that vehicle while browsing line once the side lane unimpeded, are available around the vehicle lights are uniform and regular. At this time, carry the type of people on the streets crossing the street, the motive force is frequently because of the sunlight from the vehicle blind spots. Motorists should give consideration to decelerate with the instructions prior to the vehicle was moving with the front from the vehicle once the lights change.

Shadow flicker watch out for people on the streets
If there's a shadow flashing lights, showing that there's a pedestrian before their vehicle or cyclist, and also the distance between your intersections continues to be close. To avoid sudden deceleration people on the streets must advance, don't leave items to chance to be able to avoid accidents.

Fluctuations uneven pavement lights
Additionally, with the oncoming vehicle lights to look for the road ahead fluctuations flatness, you may also make use of the vehicle tail lights observed prior to the discovery from the vehicle car headlights reflecting if the defect.

Effective utilization of the lights of other automobiles driving at night, you are able to enhance the driver's capability to judge, to prevent traffic accidents.

Front lights on first in alley
Toward the spacious urban streets, in addition to a narrow alley and mix the intersection, automobiles or people on the streets frequently all of a sudden come out of the alley, when the driver doesn't take measures to identify danger prone. When we can watch within the mouth drawn from the vehicle lighting can avoid accidents.

In the event that there's direct light from the alley, showing the automobiles drawn out of the mouth sized based on the brightness of lights and lighting can determine the peak of the vehicle: vibrant lights, everywhere for that vehicle, the lights dim, and our prime position of huge cars. Then your driver should decelerate, whistle, used interchangeably far and near lighting help remind one another.

Some auto diagnostic tools will help you test out your vehicle on your own, for example: Launch X-431 PADII, Launch X-431 PAD, Launch X431 Pro3, Autel MaxiSys MS908 and so on.

Automobile appear 3 common problems after the rain

Condition 1: driving sideslip
Rainy days is slippery, the possibility of sideslip increase in traffic, in addition to good driving habits and skills, good brake with the state of the tire was the key to safe driving. The vast majority of car braking system is dual-pipes hydraulic braking vacuum booster. The brake fluid from transfer braking is extremely strong water imbibitions. If there is water into the brake fluid, in the process of braking, the high temperature of friction produces water vapor. And gas compressibility in the brake fluid is compressed, can cause brake failure and even failure.

The solution: some serious vehicle brake fluid bibulous, in the brake fluid oil droplets can be seen on the lid. So have to check the brake fluid during maintenance, to ensure driving safety. Once found the car brake fluid bibulous serious, should send professional repair shop in addition to the water.

In addition, before the rainy season if it is found that vehicle tire wear, loss of tire, and must be replaced. Someone to reduce tire pressure every rainy season, the purpose is to make the friction between tire and ground area increases, thus increase the adhesion, actually just the opposite, it is easier to cause the tire skid, keep the normal tire pressure is very important.

Condition 2: wiper failure
If you often drive a car in the heavy rain, the line of sight is not clear is the biggest hidden danger, the importance of wipers are evident. And at this point, if the wiper conditions such as vibration or have different ring, that you be careful, because it is likely to be in it to send warning to you.

Solution: increasing the monsoon rain must let the wipers to assume more responsibility, for wiper inspection and maintenance to be more careful. Because rainy days the road and the line of sight of them are good for driving, if the wiper cannot very good brush away the rain, it will be great danger to traffic, the wiper plays an important role, so more careful inspection and maintenance of it in place.

Owners themselves put wiper switch speed of various location, pay attention to the wiper is there a vibration at work or have different ring, check whether the wipers under different speed to keep a certain velocity, the status of the wiper and wiper strut uneven whether there is a swing or leakage phenomenon. Both fault in any kind of means that the wiper blade damage. At this time can be used, with finger touch on rubber wiper blades, check for damage and elasticity. If the crack of leaf aging, hardening, or, should be timely replacement. Replacement blades work is not complicated, can do it yourself. Remember to first figure out what kind of specifications of the car wiper blade.

Condition 3: rainy day engine start
In the rainy season is the most critical for cars "heart" - the engine maintenance. The owner on a rainy day when the engine is not easy to start with, sometimes even forced up, is also a whisper.

Solution: this problem from the ignition system is the biggest reason due to damp the leakage. Once found because of ignition system of the wet and cause adverse, engine ignition performance, can temporarily use dry paper towel or dry cloth to dry distribution plate and wire inside and outside, if because of aging leakage must be replaced immediately.

Rainy days also often wade, after wading car performance due to several water fell, serious can lead to the car can't run normally. This of course, also is most likely from the ignition system leakage caused by moisture. Because rain is the best conductor, turbid in electricity after water is likely to cause a short circuit.

If the move engine stalling doesn't repeatedly ignition start-up, should wait for a period of time or checking circuit, otherwise extremely easy to cause the engine scrap. When the car should be timely after smooth wading through the circuit equipment for maintenance, can with a paper towel or dry cloth dry circuit one by one to start again.

Here we recommend some OBD diagnostic tools can help you test your car by yourself, such as: Launch X431 V Pro, Launch X431 Diagun III, Launch X431 GDS, Autel MaxiDas DS708 and so on.

Automotive steering system fault FAQs

Automobile steering system common fault is mainly: the steering wheel rotation is too large and manipulation of the instability, the front wheel, steering the heavy head, wandering. Steering wheel transport is too large, unstable manipulation check steering pump ball head, the place such as the king pin and bushing, wheel bearing wear, such as severely worn or clearance overrun. Repair should be adjusted. If no excessive wear or clearance, you should check: first, the abrasion of steering worm gear and worm, or clearance is in accordance with the provisions, such as the large clearance should be adjusted; Second, wear parts of the steering device together, or whether to adjust too loose; Third, the redirect or installation parts loose; Fourth, the steering arm loose.

When the car running deviation, can check the following: whether the tire pressure is equal to or tire diameter are equal; Whether the wheel bearing side too tight; On both sides of the spring steel plate is uneven stretch or deformation; Before the beam is correct, camber Angle are equal; Steering knuckle arm, steering knuckle for bending or deformation; Rear axle shaft for bending tube; Wheel base on both sides are equal.

Check the wheel dynamic balancing. Tire assembly is correct, check whether the tire wear uniform, check the balance block assembly is correct. Check the wheel rim for deformation; The deflection of wheels for lateral or radial swing; Shock absorber for loose or wear; Steering linkage section, horizontal, straight or redirect or assembly for loose; Spring steel, U bolt clamping bolt for loose or damage; The Angle is correct; Tire pressure is correct. Except by high-speed put head to check the contents of the project, especially emphasize the check to the top of the following: tire pressure is correct; Steering knuckle bearing ever loose; To horizontal, straight linkage section ever loose; If there's any loose for steering gear assembly; Spring steel, U bolt clamping bolt for loose or damage; Spring plate whether residual deformation.

About maintenance the car is the best way is often checked the car; you will find problems early and avoid unnecessary losses. Here we recommend some car diagnostic tools can help you test your car by yourself, such as: Launch X431 IV, Launch X-431 PAD, Launch X431 Pro3, Autel MaxiSys MS908 and so on.

Three common problems that should be paid attention to in the summer driving

Prevention tire: tire pressure down promptly repair
The hot summer is high season car tire. Due to the high temperatures, low quality or if the tire itself tire pressure is too high, the tire after gas expansion will lead to a puncture. Therefore, we recommend that owners will be tire reduced by 10%, adjusted to 2.2 kpa.

Owners should pay more attention this season on tire maintenance, if damage is discovered, it should be promptly repaired or replaced. If you have patched the tire, it is best to put the rear wheels or as a spare tire. In addition, particular attention not to let the summer tires collision obstacle, because it is easy to make the tire sidewall injuries caused problems.

Reminder: If the tire which occurs in the driving, the driver applied the hand tightly control the steering wheel, slow step on the brake, the vehicle smooth deceleration stop. Do not be an emergency brake, because it is easy to cause the flick even rollover.

Water temperature exceeded: Timely parking thermal cooling
Summer car drivers who not only baked, vehicles will be unable to withstand high temperatures, excessive water temperature is relatively common, even "boil" boiling. Summer car owners should always pay attention to see when the water table, look at whether the water tank.

Driving, if you find the water table pointer nearing the red line, it should reduce the speed as soon as the car drove into a cool place to stop. To avoid engine damage, do not immediately turn off after stopping, but should let the engine idle for a period of time before.

If the water temperature is still not fall down, you should turn off the car, check the engine coolant. But be careful not to open the radiator cap immediately, otherwise it is easy to steam burns. If it is because of lack of coolant, it would first make up.

Reminder: If the water temperature is too high the phenomenon, do not let the car on long journeys, because for a long time with a lot of damage to the engine water temperature is not under normal circumstances; do not slow down especially not choose congested roads.

Auto ignition: Reducing modified periodically check
Prevent the car ignition; the most basic method is to periodically do maintenance to the car, check the engine, and an oil circuit, to see whether the aging and oil spills. Do not store in a non-standard vehicle repair or modification, because of some wrong operation of Luanda wires, easy to friction is not effective at a fixed, will be dangerous.

If the modified car, especially lights, sound, etc., should be comprehensive examination. In the hot summer, do not lighters, fragrances, air fresheners and other flammable items placed under prolonged exposure to high temperatures inside the car to avoid swelling caused by physical explosion sparking spontaneous combustion; After a long journey, it should be appropriate to let the car rest what to avoid overload.

When driving, vehicle owners should be aware of signs of spontaneous combustion, such as an odor, abnormal sound or vehicle electrical malfunction and so on.

Reminder: The best car standing on a fire extinguisher. Once spontaneous combustion, the first car in the right place few people pull over, turn off the heat, remove the fire extinguisher, look for fire points to the part of the cooling tank and burning fire to avoid explosion.

Automotive air FAQs - 4 Tips

Still smell the air cleaning
Performance: "I'll wash myself before coming once every summer air conditioning is the fear of unpleasant smell, but not for a long time after this cleaning, find air conditioning or smell, air conditioning useless for a long time, is it going to change?"

Diagnosis: "odor generation, mostly due to the accumulation of air conditioning condensate pipe, forming a dark and humid environment, making the mold reproduction, light cleaning is palliative approach should find the problem from everyday driving habits." service department official said, a lot of people used to wait for parking was off the air conditioner, this will cause condensation deposition in the pipeline, the condensed water and airborne dust debris attached to the evaporator surface together will breed a lot of bacteria, with the wind blowing contaminated air-conditioning throughout the interior air. Therefore, the best in destination thirty-five minutes before switching off the air conditioning compressor, the fan idling, due to increase air flow, parking in front of the temperature rise inside the air conditioning ducts in order to reduce the generation of condensate, dry air-conditioning system.

Air conditioning and refrigeration effect is reduced
Performance: "There never used air conditioning six months, the weather is hot every day, every time after the start of air conditioners, will be long before refrigeration and cooling effect simply is not obvious, and there is no air conditioning around the abnormal situation, is a quick return thing? "

Diagnosis: For Nissan owners Wong this doubt, Nissan shop service manager said that some vehicle air conditioning deactivated after nearly six months, the refrigerant may have leaked, need to replenish, repair shop owners to repair the same time, remember to remind people not to forget to clean the repair evaporator and air conditioning filter, clogging them will affect the cooling effect.

After the air conditioning abnormal noise starts
Performance: "I opened the air conditioning, the air conditioning vent given the slightest sounds, there are what look was not any average every few minutes, this is what happens?"

Diagnosis: air conditioning abnormal sound is generally abnormal sound air-conditioning compressor, air conditioning compressor can feel it in the vicinity of the sound. Such abnormal sound is generally due to the refrigerant composition of air and water caused by doping. If the situation remains the same after adding refrigerant, which is located near the compressor abnormal sound position, then the compressor internal mechanical structure damage greater chance; If abnormal sound relapse after a period of time, and is located inside the center console, then dried to reduce the chance of bottles efficiency larger. After successive investigation, find the key issues in order to remedy.

Open air car difficult to mobilize
Performance: "My car displacement of only 1.3L, usually I do not gnaw with air conditioning, two days before the main is too hot, put the air conditioning turned on, I think after the open, the car is difficult to start than usual, why?"

Diagnosis: "Engine load is too large, you should first open air outside the loop" This is Ford Hunan Freshwater shop service personnel given an explanation. It is particularly worth mentioning is that if the car just after launch, immediately start the air conditioning, air conditioning maintenance practice is taboo, not only cannot play the role of rapid cooling, but also has a lot of damage to the air conditioning? According to reports, a car parked in the sun, the temperature inside the vehicle may be up to sixty to seventy degrees, you should first car windows and doors, and etc. twenty-three minutes before the heat is discharged into the launch vehicle. While the first open air outside the circle, to be close to the temperature inside and outside, and then close the window, the use of the loop. Under normal circumstances every 5,000 km or three months on the air conditioning filter cleaning once or 12 months to replace air conditioning filters every 20,000 km. This will ensure that you can enjoy the fresh clean car interior environment to ensure good health.

Here we recommend some auto diagnostic tools can help you test your car by yourself, such as: Launch X431 GDS, Launch X-431 PAD, Autel MaxiSys MS908, Autel MaxiSys Pro MS908P and so on.
