A chassis inspection, maintenance
Examination content includes the transmission parts, suspension parts is loose or damaged, such as transmission shaft, axle, semi shaft dust cover, suspension, shock absorber, screws, ball head and the chassis corrosion inspection. The ups and downs along the way to the chassis to bring sustained impact, and car four wheel positioning may also change, causes the tire abnormal wear, so the trip after returning should for the car to do a four wheel positioning. Similarly, violent vibration will damage the steering system, should observe the steering machine of ball head loose. In addition, part of the chassis of the screw should be tightened.
The owner can recall whether through chassis driving experience in the course of. At the same time, there are significant changes before and after the comparison whether car park holiday, if appear abnormal sound position of chassis, steering wheel shake, vehicle oil etc. phenomenon, means the chassis has been damaged. This is because the road obstacle scratching chassis, some parts may cause deformation of the chassis, especially in upper and lower arm, left and right direction rod easily deformed.
Some slight scraping can also cause the oil pan or wave box oil sump and so on has the slight leakage, and these are the owner to the detection can not find the problem. It is recommended to the professional norms of automobile service point shop to do professional anti rust chassis care or spray paint to do a chassis armor to.
Two, water maintenance
Oil inspection and maintenance of water inspection and maintenance of water maintenance
1, it includes engine oil, gear oil, brake booster oil, power steering oil tank antifreeze, anti boiling fluid, automatic transmission, inspection of the project are mainly:
(1) check the oil and water is enough. The lack of need to add liquid, oily bad to be replaced;
(2) check the powertrain and transmission system has no leakage of oil. Several major components such as the engine, gearbox, rear axle.
2, the engine lubrication oil how to check? Generally speaking, is to ask Wen five "three":
(1) three Q: Q: the last oil change time two asked: whether the burning oil three Q: driving the driving feeling is abnormal
(2) a smell: is there a smell (if it indicates the original oil unqualified)
(3) five see: a look: engine oil export whether there is oil or iron (if that bearing wear, should immediately repair) two see: oil cover whether there is water (such as a note pad cylinder leakage should be replaced or cleaned the crankcase ventilation Road) three see: whether there is carbon deposition (oil cap the original oil unqualified) four see: oil rule whether there are impurities (such as should be replaced with new oil) five see: oil scale scale (such as the lowest limit should add lubricating oil)
3, the engine oil change?
The extraction of waste engine oil: open the oil pumping pipe cover, the machine oil into the machine the bottom of the tank; open the oil pumping machine switch, extract oil tank oil; the waste oil pumping clean, remove the oil pumping pipe, cleaning up the oil pumping pipe of the oil stain; nitrogen gas blowing gun head alignment machine, hand blown through all the oil channel; on the other hand blown residual oil (intermittent blowing about 20 seconds)
The release of waste oil: lift vehicle lift to the working position, the waste oil collecting bucket is arranged in the engine under the bottom of the engine; unscrew the oil drain bolt, venting waste oil, waste oil to put a net, tightening the oil drain bolt;
Opened a new cleaning lubricating oil barrels, or internal engine cleaning agent bottle, idle car electronic fan rotation for 5 minutes, or 15 minutes after flameout, unscrew the oil drain bolt; the bottom of the engine, venting waste oil;
Open the oil cover, slowly into the new lubricating oil, engine oil scale master reference, adding amount;
Unscrew the oil filter of old, with a clean cloth to clean the boss on the cylinder body and the oil filter connected;
In the new oil filter replacement of the rubber sealing pad to wipe a layer of oil, tighten the new oil filter;
To the gas outlet filling oil to fuel the midline and fill the middle ruler marked, re draw back the dipstick, lid oil lid;
Remove the air filter cleaning or replacement of the new, and put back in situ;
