How to maintain the car battery in summer

Summer car battery maintenance is regularly use OBD Diagnostic Tool inspection maintenance, trailer coupling corroded battery case must be promptly treated to eliminate hidden dangers.

The heat of summer, the car in high temperature and under the hot sun, there will be a series of problems caused by high temperature and failure, often seen in the case of fire, causing casualties. Vehicle in the sun for a long time, the temperature inside the car sharply increased. It has been shown that when the outdoor temperature in 36 degrees Celsius, the car as long as two hours of exposure to the sun, the car will increase to 68 degrees Celsius temperature. It can be imagined, without the use of the Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the battery, in this environment is easy to short-circuit and spontaneous combustion.

How do the clean-up battery: lead to car battery pile head corrosion reason is battery liquid sulfuric acid. When the engine, generator will recharge the battery, the battery will produce hydrogen bubble, some acid composition will be followed by a hydrogen discharge battery, especially in charging system, such as the generator voltage is too high or charging without restraint, leads to charge excessive and so on, it will lead to a lot of sulfuric acid components into the battery on the panel to, then the two pile head will corrosion.

In addition, when the daily driving, before leaving the car, check to make sure that all lights and other electrical vehicle (such as radios, CD) has been shut down because of a long parking time will run out of battery power. Car battery to regular maintenance, carefully check the battery bolts through the vent plug, the battery will produce a large number of hydrogen, oxygen gas, once the exhaust valve failure or blockage, the pressure is too large, may cause explosion.

To avoid sparks, the pile head before the demolition of the battery, to all automotive electrical and ignition turned off, then use Autel MaxiSys MS908 or Xtool PS2 tool to check, and must remove the negative pole first, then remove the positive pole. In the back of the pile head, the positive electrode and the negative electrode. In addition, if you are not sure, it is best to consult the original operation of the factory in the process of safety precautions.

Auto Body jitter causes and solutions

Body slight jitter is the situation many owners often encountered. If the owners start the vehicle, if we find the body slightly shaking, then there is likely to mean that the vehicle under three kinds of condition:

If the driving car process, found the body there is a slight jitter or offsets, generally is a tire caused by failure. First may be tire balance condition, need the owner to do a four-wheel positioning and dynamic balance as soon as possible, if the vehicle is not running deviation do the tire dynamic balance, and then use the Auto Diagnostic Tool to check tire dynamic balance.

Another condition is more serious, may be because the steel ring caused by deformation, which requires owners to professional repair shop to check. This situation generally occurs in the use of a longer life of the vehicle body. General motors to replace the new tires, new rims must be used followed by the Launch X431 PAD or Launch X431 Creader VIII tool to check the tire balance, otherwise the weight average steering wheel is not easy to happen dithering phenomenon. Body jitter on driving comfort and manipulation of the judge will make a difference.

The third situation caused by shaft deformation imbalance, general this kind of situation in the chassis more car collision.

If there is a car body jitter, which is aimed at the vehicle equipped with manual transmission, the performance is: in the beginning and slowly lift the clutch pedal process, the vehicle has a jitter. This is due to a clutch three piece suit (flywheel, clutch plate and pressure plate) the irregular wear, in which one or a few pieces to produce deflection caused by, in the bonding process, clutch disc can not be smoothly joined, but a joint, a little and release of the engine power is just beginning to transfer, and suddenly slipped, the vehicle performance is similar jumps is feeling. Replace the damaged parts of the clutch in three pieces, and then use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check the performance of the car.

The correct way of maintenance the car handbrake

In the process of using a car parking will certainly use the handbrake. Because the driver leaves the vehicle, if not with the hand brake, then the vehicle is likely to slide and may cause an accident. Sometimes, the handbrake has pulled up, but because the brake system failure resulting in the accident. So the majority of riders should be regularly on car brake maintenance and check for proper use of Auto Diagnostic Tool. Here we introduced under the normal maintenance of the handbrake.

Handbrake lever operating position is determined
Like with the foot brake pedal, handbrake handle also has a pull stroke. Typically, when pulling the handle 70% of the entire trip, the handbrake system should be in a normal braking position, so before check braking handbrake should first find out that 70% of the working point, this work can be done through to determine the number of ratchet sound. Cars can be parked in relatively quiet place, and slowly pull the handbrake, the number of clicks while pulling ratchet issued until the end of the handle pulled up. Then calculate 70% of the total sound position, this position is the effective operating point handbrake handle, if you want to save time friend, you can use the Launch X431 PAD or Launch X431 V Pro tool detected 70 percent of the work position.

Check the handbrake mechanism Effectiveness
The car drove into a larger slope of the ramp on the road in good condition, slam the brakes, in neutral (if the automatic transmission is hanging in the N block), will work to pull the handbrake lever position just determined. Then slowly release the brake pedal, if the car does not slip occurs, it shows the effectiveness of the handbrake is good. Uphill and downhill should be done once each.

Test sensitivity handbrake
In addition to the braking efficiency, should also check the sensitivity of the handbrake, this is particularly important for the initial slope. In the absence of the slope on the road to slow down, slowly pulling handbrake handle, the handle and the sensitivity to feel joint. This method will make the handbrake mechanism wear, so check the number should not be too much. In process inspection, if found unsatisfactory handbrake brake efficiency or sensitivity can usually be by adjusting the handbrake operation cable to solve. The hand brake handle and the bottom of the cable connection (generally by the interior cover) with a tunable compensation mechanism, with wrench, loosen the lock nut, you can stretch the brake cable length. Some auto adjusting mechanism is arranged at the bottom, if inconvenient adjustment should by professional maintenance personnel to deal with, can also use Autel MaxiSys Pro MS908P or Autel MaxiScan JP701 tools to deal with.

Car battery maintenance guide

Maintenance staff said, in the car maintenance, the battery maintenance is also important. Some vehicle owners and maintenance personnel for battery maintenance do not pay attention, do not understand, did not develop good habits and cause the battery life shortened, and even damage to other electrical equipment. General battery available 2-3 years, but if you use unreasonable, 3-4 months, it may be replaced, you can check the battery through the OBD Diagnostic Tool, real-time control of battery performance.

How to determine the battery needs to be charged? Can not rely on the brightness of the headlights or sound intensity to determine the working state of the battery, you need to use the Launch X431 V+ Pro3 or Launch X431 V Pro tool to check, if the brightness of the lights dimmed, to the time when the battery has entered a state of loss, the car must not be launched. In order to ensure the normal work of the battery, the owner is best used in the battery every half an hour, start the engine to charge a battery.

Today, the car on the electric equipment more and more, such as the car after the car to use the electric power of the equipment before the headlights, tail lights, reading lights and radio or CD, so, the owner in the use of these electric equipment, as far as possible not to let the battery overload work. If flameout, no need special should first turn off the headlights, and then stall, in the night started when the car should also start the reopen after the headlight, to minimize the damage to the battery.

If you let the battery in the engine stopped state, it must prevent the battery power loss, if the loss of power is likely to cause damage to the battery. Now there is a kind of technology can repair the damaged battery, adopts pulse charging technology which will activate battery electrolyte, still can continue to use. But if losing electricity, battery will be scrapped in advance.

A 4S shop maintenance staff had said, according to use Autel MaxiDas DS708 or Xtool PS2 tool to check the battery experience, in a good car battery case, open the headlights, reading lights, radios, capacity 35Ah battery operating time is about three hours, while the capacity of 45Ah battery operating time can be a little longer, between 3-4 hours. The higher the volume of the radio or CD, the greater the power, so the battery power usage time, also consider this issue. In addition, the battery of the new and old also affect the duration of the duration of the power. If users do not install some of the original electrical appliances, such as the bass, etc., will cause the excessive use of batteries. He warned the owner, if the battery is old, working time is best not more than 2 hours.

Summer high temperatures using car easy cause four big hidden trouble

Car paint accelerated aging
Solution method: Avoid direct sunlight washing the car, the car paint surface water droplets will produce convex lens principle, would lead to further aging car paint. Try to avoid parked in the parking lot of exposure, try to use car clothing and other materials to resist ultraviolet damage the car paint, try to paint the car waxing, sealing glaze, coating maintenance scheme, use Auto Diagnostic Tool testing cars, extend the life of the paint.

Heat easily puncture occurred
Many car owners should know that the tire pressure is too low actually tire burst a factor, but we know that the summer heat also lead to a cause of tire burst.

Solution method: Tire pressure is too high and too low are not safe, maintain normal manufacturer with tire pressure is beneficial to train operation safety. Standard tire pressure generally posted on the edge of the driver's door or the back of the cap.

Door seals easy to aging
Solution method: Sealing ring every other two quarters for a clean, dry with a clean damp sponge to wipe the dust on the slide rail, trench, reoccupy dry sponge mop wipe once more, to maintain the cleanness of seal ring. Can use the maintenance products such as table board wax on the depth of the door seal for maintenance, to prevent cracking. Can be used to Launch X431 PAD or Launch X431 GDS tools to measure performance.

Interior easy to aging
Solution method: One is the paste solar film. Good solar film in addition to cut off most of the ultraviolet ray, can also play a heat insulation effect; The second is when parking for car mount the sun block, this is to protect the automobile instrument desk, a good way to the front seat.

Other Considerations
Due to summer heat and sun exposure, high temperature inside the car, the owner don't put lighters, batteries, carbonated drinks in the car, prevent because of heat explosion caused by such accidents. Regularly use Autel MaxiSys Pro MS908P or Autel MaxiScan JP701 tools to detect cars. Hot summer weather, the driver pay attention to reasonable rest, after all, high temperature and muggy weather for driver is also a test, drive safely to keep in mind.

The cause of the lubricating oil consumption too fast

Just fill the oil to the car, not a few days to check the dipstick and found that missed a lot of oil, in normal use appear this kind of problem is not normal phenomenon, called abnormal oil consumption, what are the reasons and how to deal with it? Need to use the Auto Diagnostic Tool?

The reason: the consumption of lubricating oil is divided into two kinds of normal consumption and non normal consumption. Normal consumption is because between the piston and cylinder wall as long as the movement will gap exists, regardless of gap size, there will always be a part of the oil with the up and down movement of the piston is brought into the combustion chamber with the mixture together burn. This normal consumption, the general consumption should be less than fuel consumption 1% or less. You can use the Launch X431 GDS or Launch X431 V Pro tool to check it out.

Non-normal consumption is usually because there is a fault caused by the engine itself. There are three general reasons:

First, the cylinder wall wear gap is too big, lubricating oil through the clearance between the piston and cylinder wall to burn a lot into the combustion chamber. When the tube was evident with blue smoke from the exhaust phenomenon.

Second, the oil pan and oil seals Mifengbuyan, causing oil leakage.

Third, the engine cooling bad, the engine overheated, so a lot of oil and gas generated by the crankcase ventilation tube into the inlet and the mixed gas is burned together.

Thus, if you find that the oil consumption is too fast, the engine of a system failure. To use the Autel MaxiSys MS908 or Autel MaxiDiag Pro MD801 tool to find out the reasons for repair. Of course, if you use some of the inferior oil will also appear to oil consumption too fast. So be sure to use the regular factory production of lubricating oil. In order to avoid the damage caused by engine.

Regularly check car shock absorber to ensure driving safety

Automobile shock absorber is one of the key parts of the car body, for driving safety is very important. With a period of time, be sure to use OBD Diagnostic Tool to check the shock absorber, timely repair and maintenance.

Car shock absorber if there has a leakage phenomenon, for the shock absorber is concerned, is undoubtedly a very dangerous thing. So, once the discovery of oil spills, we must make timely remedial measures. Focus of the inspection items in the oil seal, seal gasket rupture damage, storage cylinder cover, check the failure of these parts of the nut loose.

If discover leak, first tighten nut cylinder lid, but if shock absorber still leak oil, may be damage of oil seal, seal gasket failure, a new seals should be replaced. If still can't eliminate the oil spill, should pull out of the damping rod, if feel the hairpin or weight, reuse Launch X-431 PADII or Launch X431 IV GX4 tool to check whether the clearance between the piston and cylinder is too large, with or without shock absorber piston rod bending the piston connecting rod surface and the cylinder have scratches or marks.

If the damper does not leak phenomenon, should check the damper connecting pins, connecting rods, connecting hole, rubber bushings and other damage, sealing off, break or fall off place. If these were normal, should be further decomposed damper, check with the gap between the piston and cylinder is too large, cylinder with or without injury, the valve seal is good, whether the valve flap and the valve seat fitting closely, and whether the presence of shock absorber spring is too soft, or broken, grinding according to the circumstance or change a way to repair.

In addition, the shock absorber in the actual use of the sound of the failure, which is mainly due to shock absorber and leaf springs, frame or axle, rubber pad damage or fall off as well as the shock absorber tube deformation, oil shortage and other reasons, should identify the reasons, to be repaired.

Shock absorber in the inspection after repair, then use the AUTOBOSS V30 Elite or Xtool PS2 tool to check shock absorber performance, in order to ensure the maintenance effect is good, to ensure the normal use.

How to clean EFI engine fuel injection system

EFI engine is currently on the vehicle use a very wide range of equipment, compared with the conventional carbureted fuel system, EFI engine fuel supply system, not only complex, but also parts with precision. When using Auto Diagnostic Tool maintenance necessary to pay special attention.

During cleaning maintenance, some parts can not be disassembled and dismantled, some parts assembly requirement is high, which makes gasoline injection system than the carburetor type vehicles are more vulnerable to the dangers of gasoline in the colloid, sediment, the cleaning is very complex.

The engine fuel supply system, the air inlet and exhaust system are clean and have a decisive influence on the driving performance of the vehicle. Due to the impact with the environment and fuel quality injectors, intake manifold, intake and exhaust valves and the combustion chamber is easy to produce gelatinous precipitates, etc., affect the normal fuel supply, cause by fuel injection quantity control is not accurate, the fuel spray is bad, the oil pressure regulation failure, which causes the engine idle speed instability, the acceleration bad, knock, lack of fire, fuel consumption, exhaust emissions exceed the failure phenomenon. These faults can be using the Launch X-431 PAD or Launch X431 Creader VIII tool checked out.

In order to clean the oil supply system to solve the problem from the inside, they usually avoid demolition clean way. Vehicle cleaning jobs by special Autel MaxiDas DS708 or Autel Maxidiag Elite MD701 tools and equipment and cleaning agents, under certain pressure and flow control, intake manifold, fuel injectors, intake and exhaust valves and combustion chamber thorough cleaning to restore the normal operation of the fuel system, to ensure good driving performance of the car.

How to maintenance automobile suspension systems

Is the so-called suspension system, between the wheel and the vehicle body, take on the job of carrying the body and absorbing the vibration, to provide the best comfort. Under normal circumstances, the shock absorber may have a fever, if you do not explain the fever shock absorber oil spills. Car driving, each time shaking up and down, the suspension will be rattled, and when the uneven road surface noise intensified, it means suspension system malfunction, may be a shock absorber damage or shock absorber rubber sleeve damage. If you are not sure what the reason, you can use Auto Diagnostic Tool to check the car's performance.

Suspension - Shock Absorber check
Suspension system not only affect vehicle ride comfort, but also as through sex, stability and adhesion performance impact on other properties. The original is in the suspension system includes shock absorbers, springs, anti roll bars, rods and other parts. In turn, especially a sharp turn, body roll is too large, indicating that the damper, stabilizer bar, or is the guiding mechanism parts are damaged.

Brake System - Brake oil brakes
In daily use, to use Launch X-431 PAD or Launch X431 V+ Pro3 tool to check whether the vehicle brake deviation, braking performance how, and how the effect of the parking brake (handbrake) is. In the maintenance of the vehicle, the brake system must first be carried out in the brake oil inspection, such as the brake pipe is cracked, brake oil leakage, etc.. The brake pedal is also a part of the need to pay attention.

After you replace the brake pads, check whether the brake pedal return to normal, daily driving time to pay attention to prevent the mat to slide under the brake pedal, so the brakes can not be trampled to death.

Brake system plus brake fluid can not be mixed, at present, the market most cars are equipped with two braking systems: foot-controlled brake (brakes) and hand control of the parking brake (handbrake). Replace the brake fluid, must take the original brake oil finished, cannot mixed with, more can not be mixed with air inside the brake fluid. Generally speaking, the brake pads wear degree with habits have great relationship, automatic car brake pads with better than manual transmission fast, generally more than 20000 kilometers later, each time to do maintenance to use Autel MaxiSys Pro MS908P or Xtool PS2 tool to check the car brake pads. This can better protect the suspension system. If the rubber sleeve is badly damaged, it must be replaced with the shock absorber.

BMW X1 coolant temperature warning light alarm

A driving range of about 40000 km, models E84, engine type of N46 2013 BMW X1 sport-utility vehicle, there are a lot of friends reflect the car speeding coolant temperature warning light alarm, need to use Auto Diagnostic Tool detection.

Maintenance personnel to check the expansion tank in the cooling fluid is missing, there have cooling liquid leakage traces, doubt cooling system has a leak, the system for pressurized testing, good sealing.

Detecting an engine control unit, found no fault record on coolant temperature. Use the Launch X431 GDS or Launch X431 V Pro tool control cooling fan operation, to determine the fan work normal. N46 type engine water pump is a mechanical driver, as long as the engine running it will work. So will check of the opening of the emphasis on thermostat, cooling system, circulation and cooling system on the gas resistance.

In view of the vehicle mileage is not much, so doubt any wind resistance in the cooling system, cooling fluid according to standard process of adding and steam. And adjust the liquid level to the standard position. Road test, the test member come back soon, reflect the coolant temperature is high, and connect the thermostat pipe is cold. Read the circuit diagram, see the thermostat controlled by the engine control unit. In fault diagnosis instrument to observe the thermostat signal waveform, compared with the normal car found waveform, show that no control problems. Doubt thermostat has a problem, replace the thermostat test, fault is still.

After just tried to touch his hand car radiator, we found the upper and lower temperature difference, indicating that the coolant is not flowing from the interior, replace the radiator test, fault still exists. Promote the flow of the coolant pump, use Autel MaxiSys MS908 or Autel MaxiScan JP701 tool to check the pump, the pump impeller was found not rotated. Remove the water pump turned by hand, found stuck, replace the water pump test, troubleshooting.

Brake system maintenance Note

First: high temperature protection of brake pads
Prevent the brake system corrosion, prevent the brake disc from high temperature surface card die, eliminate the brake piece of screaming, maintain good lubrication lasting, need to be resistant to high temperature up to 1400C above the ceramic component products. Therefore, to regularly using the OBD Diagnostic Tool check the thickness of the brake pads or brake shoe. In the normal driving situation, the front brake of the brake pad life is 50000 - 30000 kilometers, the service life of the brake pad is 150000 - 120000 km. Once the brake wear to the limit should be replaced in a timely manner.

Second: brake wheel cylinder lubrication and maintenance
Lubrication of brake wheel cylinder shaft and cup, keep the wheel cylinder liner soft, extend the service life of the pump, need to use fully synthetic brake wheel cylinder lubricating oil.

Third: Clean brakes
Quick cleaning brakes, brake drums and any parts of grease, dirt and friction dust, keeping the brakes heat dissipation; eliminate harsh noise brakes, promote uniform brakes, use Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the brake system.

Fourth: brake oil change
Brake oil has water absorption characteristics, long time no replacement will corrode the brake system for traffic and security. It recommends that owners generally, to replace a brake fluid every 20,000 km. Mainly to ensure the cleanliness of the brake fluid.

Fifth: tire screw, brake disc and ring contact surface rust lubrication
To prevent corrosion and prevention screw and surface heating stuck, convenient disassembly, high temperature of above 1100c aluminum product ingredients, to guarantee and the brake contact area and improve the braking force, the need for regular use of Autel MaxiSys Mini MS905 or Autel MaxiDas DS708 tools to detect the brake system performance.

Buy second-hand car need to pay attention to matters

Friends often say, want to buy a used car, but do not know how to choose, do not know what to pay attention, although used car can save a lot of money, but if you buy a lot wrong with the car, not worthwhile. Have this concern is not unexpected, can not just look at the appearance and to decision, you need to use the Auto Diagnostic Tool to check the performance of the car.

Sellers To make cars look more beautiful, will advance to the car beauty and let the car looks clean, almost like new. Care of the first impression, this car certainly will leave a deep impression. Do not know the surface of cooked glamorous car, in fact there are many problems, maybe a car accident. So in the purchase of second-hand car, do not be confused by the appearance of the car.

Buy big brands of cars, that new car prices are too high, wanted to buy a used car, but luxury cars follow-up care is very troublesome, generally small repair shop can not to repair, furthermore the price is also very expensive, as well as maintenance costs, maintenance costs, might be able to buy a nice new car. In fact, more popular models and brands are the best to take care of, where can go where maintenance, cost is also reasonable, they can even use the Launch X431 IV GX4 Master or Launch X431 Diagun III tool maintenance.

Many people buy a used car through a friend, first of all is a friend and not as embarrassed openings at bargain prices, view vehicle formalities are complete, a contract's time to take a closer look, these are designed to ensure their own interests.

Cars are not consumer goods, with more or less a long time there will be some problems, so use Autel MaxiSys MS908 or Xtool PS2 tools check the condition is necessary. Check whether the body has a collision, the chassis is damaged, the exhaust pipe is rusty, as well as the engine, gearbox, water tank is leaking, seepage. The most important is the engine, the engine is the heart of the car, so should pay special attention, in addition to see the engine's appearance is dry, exhaust pipe is sealed, but also to start the car, listen to the sound of the engine is normal.

Car wiper and battery maintenance guide

How to identify under what circumstances need to replace the wiper?
1. From the wiper itself, the symptoms of damage. Identify whether there are cracks, cracks, rust, deformation, adhesion, color and so on; with ears to distinguish wiper when use whether jumping, such as jitter abnormal sound; the use of OBD Diagnostic Tool to check whether the hardening of the rubber, etc..

2. In the process of using see symptoms from the windshield. , look to whether have a slender stripe, is hard to see the outside world, this is because there is foreign body on the wiper or edge frayed, processing method first cleaning the edge part, if you do not eliminate symptoms will need to be replaced.

3. After the rain wiper is wiped, leaving a trail of water,  this is because the deformation of the rubber. If the rubber is not in contact with the glass surface, this suggests that the bracket deformation, wiper need replacing.

4. Check the wiper blade. The wiper pull up, finger touch on the cleaned rubber wiper blade, check whether there is damage, but also check whether the rubber blade has good elasticity, if the leaf aging, hardening crack, it should be replaced with new ones.

Check the battery electrolyte level should pay attention to what areas?
Check the electrolyte level, parked his car in a horizontal road, engine, by observing the battery shell on the scale line. Position, if it is difficult to determine the liquid surface of a battery, and with the aid of a lighting to see, can also use the Launch X431 GDS or Launch X431 V Pro tools to check the electrolyte level.

New battery is provided with an indicator, can through the indicator to check the status of the battery. Indicator on the green dots obviously show that the battery in good condition: a green dot blur, shows that lack of electricity: dots become transparent or yellow, indicate the need to replace the battery.

Its different battery indicator is displayed may be different. through Autel MaxiSys Mini MS905 or Autel MaxiScan JP701 tools real time data display, if the battery indicator is blue when normal, insufficient amount of electrolyte is red, when white needs recharging. There's battery level indicator at the square hole below the liquid level is too low, when the indicator of the level below the square hole for liquid level is too low, as it happens and square hole level as the standard, more than at the bottom of the square hole and filled with liquid mouth when too much for the amount of electrolyte.

How to replace the fuel filter

Before trying to repair the car you have to always wear goggles, when necessary, still need to wear the PPE personal protective equipment, such as latex gloves or closed type shoes. Keep in mind that petrol is highly combustible, and when you are ready to deal with the fuel system to ensure that there is a fire extinguisher and Auto Diagnostic Tool, to prohibit smoking, to ensure that the fire away from the car or fuel tank, must be careful when working.

Steps:
1. To park the car on a solid plane.

2. Reduce pressure fuel system (fuel injection systems operate at very high pressure environment, the need to reduce pressure), follow these steps:
