Timely attention to automotive air filter maintenance

Replace "three filter" according to the use of the car, maintenance and oil quality grade circumstances, automotive air filter equivalent to the human nose, the air entering the engine to go through the first hurdle, Filter the air through the blocking effect of filter paper. When the dust of the filter paper surface of the pores, it will cause blockage, which directly affect the car's engine, unimaginable consequences occur. Because the air filter and direct contact with the outside world, so it is easy to be blocked, through Auto Diagnostic Tool check found engine will accelerate the powerless and idle instability, and other symptoms, the normal work of the air filter can avoid premature engine wear and maintain the best working condition.

The density of the atmosphere contains three different basic particle contaminants that dust, debris and soot. Open highway dust content is low, but emissions from vehicles concentrated, so that the content of carbon particles in the air is significantly higher, and therefore frequently used Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the air filter. The dust concentration in the larger areas such as construction sites, sand area, air filter inspection and replacement frequency to be higher. Also now the majority of automotive air filter is made of paper, when the damp air filter, intake blocked, weak acceleration of the vehicle becomes more serious when the water is drawn into the interior of the engine into the cylinder, since water is incompressible, seriously damaged will cause the engine internal moving parts, engine even scrapped.

Few people noticed it, but auto parts Once the problem occurs, the result is the most serious threats to travel safety, not because these small parts and components affecting the active force of the car, so regular use Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool to check car engine working conditions.

Automatic transmission car maintenance knowledge

Automobile automatic transmission, manual and semi-automatic transmission car, three different types of operation of motor vehicle, automatic transmission car is easiest, many opened automatic transmission cars have awareness in this regard, therefore automatic transmission car compared with those of other two kinds of car electronic devices will be more, should pay attention to in the maintenance of more, also need to use professional Auto Diagnostic Tool repair, therefore, compared with the other two cars, vehicle with an automatic transmission is more difficult to maintenance, here to introduce some automatic-shift cars maintenance knowledge.

1. Always check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, check the engine oil in the cold state, and transmission oil is needed to oil preheated to about 50 ℃, then to block a rod in each block for 2 seconds in a stop block, the oil dipstick normal oil level should be between the highest and the lowest line, such as not enough, it is timely to add the same quality oil.

2. Correct replacement of transmission oil. Presently preferred method is dynamic change oil, cleaning equipment using a dedicated gearbox, in the gearbox during operation, the old oil full circle, emissions clean, add a new gearbox oil, so oil change rate is as high as 90%, to ensure good oil effect.

3. Master replacement of automatic transmission oil cycle. Automatic transmission internal control mechanism is very precise, with a small gap, so most manufacturers recommend automatic transmission oil change is usually two years or 40,000 to 60,000 km. During normal use, the transmission fluid temperature is generally around 120 degrees Celsius, so the quality of oil in demanding, must also be kept clean, as well as regular use Launch X431 V Pro or Launch X431 V+ Pro3 tools to detect. Secondly, gearbox oil to use after a long time will produce grease, it is possible to form sludge, will increase the friction plate and the parts wear, but also the influence of hydraulic system, make the power transfer is affected. Third, the dirty oil sludge will enable each valve body moving smoothly, hydraulic control affected, so that the automatic transmission abnormal.

Automatic transmission vehicle maintenance and repair in strict accordance with the maintenance manual to repair, encountered do not understand the situation, do not go to their private to deal with, go to a specialized repair shop or 4S shops to consult professional people, but the best maintenance method is usually the correct use of the car, regular use Autel MaxiTPMS TS501 or Autel MaxiTPMS TS601 tool to check the car's overall situation.

Regular maintenance and check car handbrake

In the big city in the congestion of the car, the vehicle before and after the gap is basically less than one meter, and the slope of the overpass is very large, parking brake is particularly important. However, due to various reasons, the handbrake will appear when no use. In the daily inspection and maintenance of the vehicle, don't forget to use Auto Diagnostic Tool to check the performance of regular handbrake.

First, determine the operating position of the handbrake lever. Generally, when the handle is pulled three-quarters of the entire trip, the hand brake system should be in a normal brake position. Should first find out the work point, the general 5~7 case is normal position. Then check the brake mechanism efficiency, also is have a look handbrake to work effectively. The car drove up to the steep, good road conditions of the slope, step on the brake pedal, the neutral gear, pull the hand brake handle to just to determine the position of. Slowly loosen the brake pedal, if the car did not happen sliding, that means the hand brake performance is good.

Check the handbrake sensitivity, since it is very important to the slope. On flat roads slow driving, slowly pulling handbrake handle and feel the sensitivity and the junction of the handle. If it is found that the brake braking efficiency or sensitivity is not ideal, can regulate the handbrake thread through Launch X431 PAD or Launch X431 GDS tools to solve.

Adjust the hand brake wire. If found in the test the brake is not sensitive, can be solved by adjusting the handbrake arrows, below the hand brake handle with an adjustable compensation institution. Adjust the need to remove the handle decoration cover first, then use tools to adjust the length of stay, in order to ensure the hand brake is in the best working state.

Ordinary driving, the handbrake usage is very high, but the handbrake is not universal insurance, its performance will decline with the increase of using the number of times. Most of the time, because the system failure or improper use and don't effect, this is also the major hidden danger of the accident, so owners should regularly use the Autel Maxidiag Elite MD701 or Autel MaxiDiag Elite MD802 tools maintenance check handbrake.

Maintenance and inspection method of automobile shock absorber

Automotive shock absorber is used to suppress the shock of spring when the shock and the impact from the pavement. The spring can be used to filter the vibration of the pavement, but the spring itself will have a reciprocating motion, and the shock absorber is used to suppress the spring jump. Through Auto Diagnostic Tool checking, the shock absorber is too soft, the body will be jumping up and down, shock absorber is too hard will bring too much resistance, interfere with the normal work of the shock absorber. Teach you how to maintain the working effect of shock absorber and how to check it.

1, Oil seal gasket, sealing gasket rupture damage, storage cylinder cover nut loose. May be oil seal, seal gasket damage, should be replaced with new seals. If you still can not eliminate oil leakage, should pull out spring strut, if feel the card or not at that time, light and heavy, then, using the gap between Launch X431 V Pro or Launch X431 Diagun III tool to check the piston and cylinder is too large, shock absorber piston connecting rod for bending, the piston connecting rod surface and the cylinder have scratches or marks.

2, Press firmly on the bumper, then release, if the car has 2 or 3 times to jump, then the shock absorber works well.

3, when the car slowly driving and emergency braking, if the car more intense vibration, there is something wrong with the shock absorber.

4, Remove the shock absorber to its upright, and the lower end of the connecting ring folder on the vise, pull compression damping lever several times, then there should be a stable resistance, pull up resistance should be greater than pressed down resistance, such as resistance to unstable or no resistance may be internal shock absorber valve parts lacking fuel or damage should be repaired or replaced.

5, in determining the shock absorber problem or failure, should first check the shock absorber for leaks or traces of old oil spills.

6, To make the car drive 10km on the poor condition of roads on the road parking, touch the shock absorber shell, if not very hot, no resistance in the shock absorber, shock absorber does not work. At this point, can be added to the appropriate lubricating oil, and then test, if the shell fever, for the shock absorber internal lack of oil, should refuel; otherwise, the shock absorber failure.

7, if the damper does not leak phenomenon, should check the shock absorber connection pin, connecting rod, connecting hole, rubber bushings and other damage, sealing off, break or fall off place. If these were normal, should be further decomposed shock absorbers, check with the gap between the piston and cylinder is too large cylinder with or without injury, the valve seal is good, the valves and valve seat are tight fitting and Save Dilatation shock absorber spring is too soft or broken, take grinding to repair or replace parts of the approach according to the situation.

8, In addition, shock absorber in actual use will rattle the fault, which is mainly due to the shock absorber and the steel plate spring and frame or shaft of the collision, the rubber pad damage or loss and damper dust-proof cylinder deformation, caused by insufficient oil should be to identify the reasons, to be repaired.

9, shock absorbers after the inspection, repair should be in a special test stand performance test, when the resistance frequency at 100 ± 1mm, which stretch stroke and stroke compression resistance should meet the requirements, showed normal shock absorber.

I suggest that you use by bumper way to check on how the working conditions of the shock absorber. Because this approach is simple and relatively less time-consuming, but also very intuitive and accurate test results. You should regularly check the shock absorbers have no oil leakage, and if there is leakage oil will affect its work, should go to 4S shop use professional Autel MaxiSys Pro MS908P or Autel MaxiSys Mini MS905 tools for maintenance.

Automotive timing belt function and check methods

The engine timing belt also called a toothed belt, The crankshaft and camshaft are connected by the above tooth groove. We know that the engine is in normal and stable work, the movement of the piston position, the valve open and close time, fuel injection and ignition time must be synchronized, and this is accomplished through the timing belt, you can use the Auto Diagnostic Tool to check the timing belt working performance.

Timing belt belongs to the rubber parts, with the increase of engine working time, timing belt and timing belt accessories, such as timing belt tensioner and pumps will wear or aging. If can cause the vehicle broke down after fracture belt, the engine internal valve damage, serious can cause the abandonment of cylinder cover. Not only to spend more, but also a long time to repair. Therefore, we need to use the Launch Diagnostic Tool or Autel Diagnostic Tool regularly to check and maintain the timing belt.

Check automobile engine belt consists of two elements:
First, check the belt tension, then you can use the thumb, strongly pressed the middle two belt pulleys. The pressing force of about 10kg, if the reduction of the belt is about 10mm, is considered proper belt tension exactly. If excessive pressure is considered insufficient belt tension. If the belt hardly occurs reduction is considered excessive belt tension. When the lack of tension, the belt is prone to slipping. The tension is too large, it is easy to damage various auxiliary bearings. For this reason, it should be related to the adjusting nut or bolt loosen the belt tension adjustment to the best state.

In addition, it must be noted that the wear of the belt. Old belt badly worn, the belt and pulley contact area dropped. Then as long as the force of a press belt, the belt will sink deep into the pulley groove. If the belt rubber is aging, must promptly replace the new belt.

Xtool PS2 or Autoboss V30 SPX tool inspection data show that cars generally every 80,000 km replace the timing belt; five-valve cars are generally replaced every 60,000 kilometers per timing belt. It should be noted when replacing the timing belt, appendages such as tension pulley, water pump should be replaced together.

Nano fuel additives basic knowledge

Nano fuel additive is a functional material to make up for the defects of the fuel in some properties and to give some new properties of fuel. It has washing, dispersion, emulsion breaking, antioxidant, promoting burning, corrosion, rust, lubrication, cleaning function. According to Auto Diagnostic Tool tests show that nano-saving device is mounted on the pipe of the car, after the installation of this equipment can purify exhaust gas by 50% -90%, 10% -30% fuel savings, enhance the power of 10% -30%, reduce engine noise, suppression coke production, clean combustion and prolong engine life.

Maintenance and good driving habits is the key to saving, The best fuel-efficient way is at ordinary times to use the Launch X431 PAD or Launch X431 GDS tools check vehicle, to develop good driving habits. Do not always emergency braking or hard acceleration. Energy-saving cars "four bogey." A bogey, since often require hard acceleration, braking, fuel consumption ratio will increase 2-3 times uniform; two bogey, pay attention to traffic conditions ahead, without prior dodge or slow down in advance, the car will see the red light or experience, rely on the emergency brakes, natural fuel soared; three bogey, high speed and low-speed operation, the engine idle for a long time; four bogey for a long time over economic speed driving.

Nano fuel additives Product features: can effectively protect the engine, it can increase the useful life of an automobile engine and some 5 - 10 years, based on Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool checks show can effectively fuel-efficient 5-16.6%, remove carbon deposition by more than 95%, the noise of the engine has also dropped. Nano fuel additive has a clean, dispersion, emulsion breaking and promote burning effect, after clear the carbon deposit in fuel oil, through the "microburst", promote burning, finally to reduce emissions, eliminate exhaust black smoke.

Automotive transmission belt regularly checked guide

The car drive belt is responsible for all parts of the movement, if it bad the car can not move. Because the engine is driven by a belt drive all kinds of auxiliary mechanism, such as an air conditioner compressor, power steering pump, alternator, etc., if the belt is broken, or there has been slippage, will be related to the loss of the auxiliary mechanism, or its performance decline, thereby affecting the normal use of the car. Therefore, it is necessary to check the drive belt regularly using Auto Diagnostic Tool.

Belt inspection method is very simple. First, check the belt tension, select the longest unsupported belt span intermediate applying moderate pressure with your thumb, if the reduction is about 10 mm in the belt, that the belt tension is just right. If the belt tension is too large, or too loose, it could result in slippery tooth, transmission is incomplete. And adjust the belt too tight, so that the belt is easy to tensile deformation, but also accelerate the pulley and bearing wear. For this reason, it should be related to the adjusting nut or bolt loosen the belt tension adjustment to the best, if you are not sure the best, you can use the Launch X431 V+ Pro3 or Launch X431 CResetter II tool check the belt the best condition.

In addition, in daily inspection should pay special attention to the wear of the belt. Because if the belt wear is serious, it will cause the belt and the belt pulley contact area to drop sharply. At this time, as long as a pressure belt, the belt is deep down to the groove of the belt pulley.

Also, if you find the belt surface cracks and spalling cracks appear phenomena such as sound or belt slipping occurs, indicating the belt may be broken and must be replaced immediately. If not promptly replaced, the belt once in a moving way break, the vehicle will not be normal driving.

In actual use, check and replace the automobile belts are very complex, generally professionals using the Autoboss V30 SPX or Autel Maxidiag Elite MD702 tool operation. Moreover, because the price of the belt is not particularly expensive, often change in time before the arrival of the service life of the belt is a common choice.
