Idle operating time is too prolonged leads to the water temperature is as well high.
Symptom: Engine idle working time is as well long will "boil", when instruments in the large temperature warning light is lit.
Troubleshooting: Parking examination identified that electronic fan is just not operating. Users say the car due to engine failure has repeatedly higher upkeep, has changed many instances thermostat to the initially time after the substitute, but not extended in advance of failure might be reproduced. Later on, and after that change the thermostat will not aid. It is actually linked to a temporary handle line, using the guide switch in the cab according towards the instructions about the coolant temperature gauge human handle.
Unplug the machine lid open following the initial thermostat switch plugs, wiring are linked using a quick circuit from the 1,three and 1,2 jack, turn the ignition switch to "ON" block and discovered that only a high-speed, electronic fan not minimal, with an infrared thermometer to your upper and decrease pipes for testing and uncovered consistent coolant temperature, indicating that the engine cooling technique is regular. It looks failure or while in the electronic fan element. Car Repair 'Home
Infrared thermometer measuring temperature manage switch and then throughout the tank wall temperature, at about 95?, and the measurement temperature switch copper cap portion, the temperature will not be so high, indicating the perceived temperature thermostat and also the temperature of the coolant itself inconsistent. Suspect thermostat sensor plug may well exist throughout the foreign body, then eliminate the thermostat and found no mounting holes to drain antifreeze. Use a screwdriver to poke holes, sudden outflow of coolant in the hole and fell from a scale, thus the trouble suddenly. Mounting holes around the thermostat following cleansing all over within, and put around the unique thermostat, refill antifreeze check, all the things is typical.

How should the novice driving in the garage and Precautions
Just take the driver's obd2 code reader license for novice, into the garage was quite a thing to fear, in the garage must pay attention to the process of moving the following:
1 Be sure to open the headlights.
Basement environment is a complex area, do not think their own spaces, and out every day, hundreds of times, have you ever noticed the basement of vehicles are sometimes not as you think you parked neatly out of the basement, there are many pedestrians (especially in is commuting), also sometimes cleaning, maintenance, security personnel access, and even occasionally there will not know the depth of child ...... Do not tell me the basement of your home lighting is very good, open headlights not let you see pavement, but let you tell people: I'm here, I'm coming, please note. I have more than once in a turn, downhill, and out of their parking spaces almost hit another car, it is because they do not turn on the lights. Basement, in the rearview mirror, no lights of the car it is too conspicuous!
(2) Unless otherwise required, do not whistle.
Some people say, I do not turn on the lights, I tell people I came whistle. You are wrong. In the basement is a very confusing place reverb, all sides walls (especially multi-basement, my house is 5 layers) so the sound bounces back and forth, a sense of direction is extremely confusing, difficult to distinguish between a person outside the vehicle in the direction the sound , source. The role of whistle warning to others is extremely limited. Moreover, there is an opportunity we can give it a try, if you are pedestrians walking in the basement, the basement horn after amplification, reverb later how harsh! Can be said to be very annoying for.
3 strictly car scanner follow the signs marked lane.
Our district is a 5-storey underground basement structure, multiple lanes, downhill, export, if there is no sign, a novice or unfamiliar visitors may even get lost in it. Fortunately, a variety of marking is complete, just let me every day to find their own parking space .... but some students from that hundreds of times, chaotic turn around, turn chaos. Some even retrograde. This is inside the danger I do not say, sight is not good plus illegal retrograde .........
4 parking into place, do not Luantingluanfang
Imagine, if you encounter a downhill in the basement (25 degrees), a width of about 6 meters, the length of about 8 meters, you have to turn left onto the ramp to 90 degrees, 90 degrees downhill and then is immediately left turn into the corner when you suddenly find your right after the two cars parked on the ramp, you're left with a width of only four meters up! Then what will you? This situation in our land Curry have occurred, parked in the driveway may feel so big a car you can not see? But if hit .......
5 Remember the road and into your parking location, then look at the way out
Right here is that you are not familiar with the basement, such as those on the street offices, shops or something. And now, more and more libraries even old driver, went without any problems, not I find the way out, or sometimes simply can not find his car, and this is nothing new. Basement structure inherently complex, and some signs and markings are not very clear, scientific. Parked the car, be sure to find out that she had stopped in the first layers, the first few numbers, if there is no number, what features to look around the terrain. Here we should note, a. Sometimes you actually think that the characteristics of the terrain are everywhere this garage, for example pillars, railings, stairs or something. b. better not to the side of the car as a reference, if the others go of it? !
Under lock car would not have said, do not rush to leave after getting off work, it is best to see this library has several export, are an avenue through which to the outside. Ask who is also a good choice.
6 promising children, do not let them run around
Was hit by another car, or lost in the maze of the garage just a little accident .... enough you regret .....
7 running slowly
You will always have unexpected things in the garage so strange in the familiar garage is no exception. Sight is not good, the situation is unknown to Curry, maintained at 5KM / h following are the most sensible, even with the case, the loss is not as much .......
8 Carefully height limit
It goes without saying, we plot took place over a modified cross-country is stuck in the entrance (the photo is the place), engage in more than an hour before, and very good on the roof luggage rack also scrapped ...... ..
9 Smoking
It is said that sometimes auto diagnostic tools the basement oil too thick, smoking causes deflagration ....... this is not verified, but no experience. When is smoking advertising it! After all, benefits the country .......
Initially thought so much of my own more than six out of the basement of a variety of experiences, if there are irregularities, heroes welcome correction, supplement!

How to reduce driver fatigue
Seat position should be moderate
Do not excessively high speed
Eat light
Statistics show that car diagnostic tool in the case of deaths caused by traffic accidents, because the driver drowsiness, fatigue driving deaths caused by more than half. Eliminate or reduce driver fatigue can enhance traffic safety, but also can reduce the driver's labor intensity. Here are some tips.
People, vehicles and the environment caused by driver fatigue
Driver's own situation: young people than older people are more easily fatigued; women than men are more easily fatigued, novice drivers are more than the old fatigue; lack of sleep are more prone to fatigue.
Neighborhood: such as driving the indoor temperature, humidity, noise, ventilation, etc., whether traveling monotonous scenery along the road, pedestrians and vehicles are congestion and so on.
Vehicle condition: such as seat comfort, can multi-adjustable, whether lumbar support; whether the vehicle has cruise control, power steering whether there; whether the engine is running smoothly and so quiet.
Prepare papers
1, power steering: steering wheel with power steering vehicles will be particularly light, no power systems, steering will be tight for blunt, straight-ahead driving feel no difference, but once the transfer direction of the difference is obvious, since the major vehicle particularly evident.
2, damping Steering: steering wheel is the main way driver's perception of the road, which makes the steering wheel vibration than other parts of the obvious, for some hard texture of the optional steering wheel cover, hands and body to reduce driver fatigue.
3, clear gear: For manual transmission cars, the frequent shifting is unavoidable, especially in urban areas, if the gear is very clear and easy to hang will be very labor-saving, but also reduce driver fatigue, and if possible choose automatic block models. Another example is the brake pedal, accelerator pedal, clutch pedal should be adjusted to the smooth operation of the extent to which the worker may ask the master to the repair field to help solve.
4, to maintain obd2 scanner a good mood: the driver must maintain a good mood, do not let the emotional impact of a variety of trivial things, distracted.
5, adequate sleep: As a driver, itself must ensure adequate sleep, seven hours of sleep a day is essential to maintain a regular lifestyle.
6, eating light: the driver in the diet to try to keep light, avoid those greasy fried foods aggravate cardiovascular burden.
7, good health: in particular, a number of seemingly very mild symptoms, such as colds, etc. so that the driver decreased attention, and that physical discomfort will accelerate fatigue soon.
Start articles
1, the seat height is moderate: the seat is too high, the driver is easy to hump while driving, even keep straight posture, will seem stiff, convenient operation.
2, front and rear seat properly: step on the ball of your foot on the clutch pedal completely trampled to death, the whole leg still maintain a certain degree of curvature, so that accidents can be a buffer space, but also reduce leg fatigue.
3, the body some distance from the steering wheel: the distance between the body and the wheel well is that when the arm is straight, the wrist can ride just above the spokes on the steering wheel.
4, the seat can be tilted backwards slightly: This allows the body to maintain balance while driving, relieve pressure on the neck and back. For vehicles without lumbar support functions, with the seat in the gap at the back plus a lumbar pad, long-distance driving feel more comfortable.
The way articles
1, more rest: For long-distance driving, every two hours will take the initiative to step aside to stop, get off the rest 10-15 minutes, the eyes look into the distance, twisting twisting the body, relax the ankle.
2, driving more ventilation auto code reader: In the driving process has been feeling sleepy, you can also open the windows and air out, put the different styles of music, painting wind spirits, chewing gum, and talk with the car and so reduce crew fatigue . Without affecting the safety of the premise, can stretch finger, shook arms, shilly-neck, eyes looking into the distance as far as possible, always staring at the centerline easy to make visual fatigue.
3, the control speed: high speed, easy to make the driver nervous, without affecting the traffic cases, slightly lower than the normal speed to reduce stress, reduce fatigue. Also, when traveling to minimize overtaking, reducing emergency braking action, also reduce fatigue.
Do not excessively high speed

Car rearview mirror adjustment techniques
Car diagnostic tool rearview mirror is an essential object, the driver "behind the eyes" in the safe driving plays a very important role, therefore, be adjusted, for safe driving is particularly important, then, how to properly adjust the car Mirrors do?
Each car is equipped with three mirrors, namely the left mirror, right mirror and central rear view mirror. Most cars are equipped with anti-glare interior mirror, in order to prevent the rear of the vehicle when driving at night glare caused dizziness, flip it up when used, which can dilute the principle behind the use of light refraction, making it clear judgment had cars and drivers relative position of his car; while luxury cars are also equipped with electric exterior mirrors demisting function and surface design, make it clear enough I seek greater angle image space.
Next, introduce auto code scanner rearview mirror adjustment method:
First, adjust the posture can adjust the rear-view mirror;
Second, is to adjust the rearview mirror:
(A) the central rearview mirror adjustment: left, right position adjustment to the left edge of the mirror, cut to his right ear in the mirror image of the occasion, under normal circumstances, from the central rearview mirror to see themselves, and upper and lower positions are placed in the distant horizon, the central mirror, adjust the essentials are: horizontal pendulum middle, put the left ear, which placed a distant horizon cross the midline of the central rearview mirror position, and then move around the his right ear mirror image on the left edge;
(2) Adjust the left rear view mirror: the upper and lower position is placed in the center of the distant horizon, left and right body position is adjusted to account for specular range 1/4;
(3) the right side mirror adjustment: the driver's seat on the left side, the right side of the body so the driver is difficult to grasp the situation, therefore, the adjustment on the right side rear-view mirror, the position should be bigger surface area, mirror area about 2/3, and the left and right locations are adjusted to the same range of the mirror body occupies 1/4.
In addition, many people believe that to eliminate the dead line of sight, you should try to put the left and right rear-view mirror or to cut out of tune, in fact, this is a misunderstanding, under normal circumstances, the driver in the eye and not just turn back, you can see front range of about 200 degrees, while the other is in the range of about 160 degrees to see, in fact, use the left and right side mirrors and central rear-view mirror, and then only to provide additional visual range of about 60 degrees, while the remaining 100 degrees to allow the driver to take look back only way to solve, although many new cars are equipped with a double curvature of the mirrors, but this is just to the left and right rear-view mirror perspective of expanding the scope of some still can not full coverage of all areas.
As the market selling cars obd2 scan tool are equipped with interior mirror mostly small, it is recommended that you purchase riders to wide-angle rearview mirror car boutiques, although the interior mirror surface design shines a larger area, but there are scenes distortion shortcomings, so buy Shihai plane mirror is appropriate in order to avoid dizziness.

How to Replace Car Coolant
Automotive repair by car diagnostic tool and maintenance of general automotive coolant should be replaced every two years, the replacement of steps and precautions are as follows:
(A) release of coolant: First sump lid open (note at this time the radiator cap should be sealed tightly), unscrew the cylinder block and the radiator liquid discharge switch, the engine speed should be hot like circumstances.
(2) adding a new coolant.
Note:
1, to be exhausted after the coolant should tighten up the cylinder block and the radiator fluid switch.
2, from the provisions of the radiator filling liquid inlet coolant storage tank until the coolant fluid level reaches a predetermined "FULL".
3, at this time, car key programmer cover the radiator cap, let the engine run until normal operating temperature, stop stalling after cooling to room temperature.
4, and then observe the storage tank liquid level, as appropriate, add, until the engine idling, the liquid storage tank without air appear as well.

Car in motion machine lamp shining what is the reason?
Cars with timing lamp shining reason
First, only the normal obd2 code reader oil pressure in order to guarantee that all of the engine oil to the friction surface, too high or too low will affect the engine to work properly, and even cause damage to engine parts, so when the oil light should be shut down immediately find the cause alarm until troubleshooting before continue working.
Car alarm lamp produces machine general reasons are:
1, oil fuel shortage: If the oil fuel shortage, the fuel pump will reduce the pump or the pump is not because of oil into the air, causing the oil pressure drops.
2, the engine temperature is too high, easy to make oil thinning, with the gap from the loss of a large number of leading oil pressure drop.
3, Car diagnostic tool oil pump failure: When the oil pump damaged, or worn parts, assemblies and other problems the gap is too large, no oil will cause pump failure or lack of oil.
4, crankshaft and large, with the gap between small tile improper: oil pressure will rise too tight, too loose will make the oil pressure is reduced.
5, oil filter, oil disc clogging oil pressure will also decrease.
6, the oil return valve damage or malfunction: If the main oil return valve spring fatigue softening or improperly adjusted, the mating surfaces of the valve seat and ball worn or loose dirt stuck closed, the return will significantly increase the amount of oil , the main oil hydraulic also decreased.
7, oil improper selection: If you use the wrong or improper selection of grades, when the auto code scanner engine is running too low due to oil viscosity increased leakage, so that the oil pressure decreases.
8, the oil pipeline in oil, clogging.

Basic Principles of Automotive suspension system constitutes
Increasingly focused on LAUNCH X431 iDiag the modern car ride comfort, so that consumers tend to buy car comfort as an important measure. In fact, in addition to car ride comfort softness of the seat, the support force and other factors, the most relevant is the car's suspension system which is connected between the frame and the axle force transmission parts, such as traveling to other properties security, through sex, stability and adhesion properties have a significant impact.
Basic structure of the suspension system
Simply put, automotive suspension including elastic components, shock absorbers and power transmission devices, three parts, namely, a buffer, damping and force transmission effect.
From cars in terms of the elastic element multi-finger coil springs, only withstand the vertical loads, uneven road surfaces and inhibition of easing the impact of the body, with a footprint no lubrication filial filial quality advantages, but because there is no friction and no damping itself effect. Hydraulic Shock Absorber shock absorber also refers, its function is to accelerate the attenuation of the vibration of the body, it is also the suspension system is the most sophisticated and complex piece of machinery. Power transmission device refers to the upper and lower arm, etc. fork frame steel frame, steering knuckles and other components used to transmit longitudinal forces, lateral forces and moments, and to ensure that the wheels relative to the frame to determine the relative motion of a law.
In practice, as long as the same with the possible role of the three.
Cars with independent suspension into a trend
Suspension system car diagnostic tool two classifications:
(L) Non-independent Suspension: non-independent suspension mounted on a wheel axle ends of the whole, so that when the wheels running while beating, it will also affect the other side of the wheel to make corresponding beating, so that the whole body vibration or tilt. Take this car suspension system generally poor stability and comfort, but because of its simple structure, large capacity, the suspension used for trucks, buses and some other common special vehicles.
(2) independent suspension: independent suspension axle LAUNCH X431 iDiag is divided into two sections, each wheel independently with coil spring mounted on the frame below, so that when the wheel while beating occurred, the other side of the wheel is not directly affected, significantly reducing body vibration , automotive comfort also able to greatly improved, especially in the high-speed roads, it can also improve the car's driving stability. However, this suspension structure is relatively complex, a small capacity, but also related to the car drive system, steering system becomes complicated. Most cars have front and rear suspension independent suspension uses a form, and has become a trend.
Independent suspension structure divided candle, McPherson, link type etc., which are similar in shape candle and McPherson, both the coil spring and shock absorber together, but the structure there are significant differences different. Candle using the pin moves along the main wheel suspension form, shaped like a candle is named, is characterized by kingpin position and wheel alignment angle is not jumping up and down with the wheels of change, is conducive to vehicle handling and stability. McPherson strut type is twisted with the lower wishbone suspension consisting of forms of shock absorbers can cater steering kingpin, steering knuckle can rotate around it, is characterized by kingpin position and wheel alignment angle with the wheels jumping up and down and change, with candle suspension just the opposite. The suspension structure is simple, compact arrangement, small changes in wheel alignment, with good driving stability. So, now the most used cars independent suspension is MacPherson suspension.
