first step: to look at cars chassis and battery
you say, so what's good-looking car? Wrong, the new car is also leaking! Body did not get on the ground to see underground oil point, the chassis has not oil. Car battery can see more of nothing, just look at whether the connector is green corrosion and a small window on the line. Note that the battery connector is usually loose, and drove away the former must JS tightened.
Step two: Pull out the oil-foot to see the oil color
was also said that not all 0 km it? Of course, the But dealers bad yet, and some cars run a lot of miles, but the odometer does not take, or more than ten kilometers, posing stunned 0 km! When looking at the car three minutes to turn off the engine oil dipstick out wipe with a paper towel, oil black out. JS has also now know that, so yesterday, even asked to inspect, the dealer even highlighted the intention of immediately, people have been prepared to see a pebble.
third step: listen to the engine sound
I usually develop a habit of driving, what cars are as long as it opens the first to open the front cover, top with a screwdriver on the engine side, the other side of the top of the ear to listen to the sound, be regarded as the accumulation of experience. The hand-pick the car a big help, almost half of the cars out to the remaining two. (Do not laugh! Pick the car or something so fine you better be careful, you are the more serious the more dealers you can not slack!) To elaborate on here, so you can hear the sound of the engine if the internal noise, such as the sound of the rings , Knocking sound, valve beeps and so on. There is only one good engine 'grunt grunt' sound, no other noise. However, this method usually depends on the conscious conduct of accumulated experience, a few words he could not, in short, is good to listen to more cars. Wordy sentence: someone can help, should he step on the gas-liter engine speed you hear the sound. And then to block what he rags to block the exhaust port, if the engine sound was changed a few seconds to sink and turn off the engine is a good car! Otherwise, where is the leak. (I had to block their own, the dealers do not look! Hehe.)
Step Four: Start the engine speed at cold start when the note changes in the table pointer
Under normal circumstances
pointer should turn around to hit 1600, then slipped to 800 normal smooth transfer (winter outdoor experience in the north down to 1200 rpm car is about to start getting hot car after a few minutes back to 800 rpm). And observe a variety of instrumentation and alarm device is working properly, when the water temperature and oil pressure is normal,
monster beats headphones, the sound of the engine to pass inspection and reflect, first of all to listen to the voice of idle should be smooth and continuous and should not be a metal percussion sound and other abnormal sound.
smoke off the exhaust pipe is normally observed, put his hand to feel the exhaust vent is a continuous, normal should be made of organic palm moist but not greasy, and then listen to the engine sound is slow refueling continuous and any abnormal sound, and finally listen to the voice of hard acceleration and engine throttle reflect on the accuracy and rapid, but also pay attention to slow and fast oil revenues when oil revenues reflect the engine is clean and, if delayed, or high-speed whistle, should be there is a problem. Lost throttle (accelerator pedal relaxation) idle is stable. Resting place, whether the engine speed to 3500 rpm have different roar.
Step Five: Check the work
connection depends on the situation of each thread
whether there shaking, etc., that you will own view, not much to say.
Step Six: see the whole car look.
Some would say that you only see the appearance at this time ah? Of course, this is not the pick used car, look if there are scratches, this car does not stop there for you pick, the dealer will deal with early in the morning, I want you to see the appearance of a door gap is not equal. In addition, we must pay attention when watching the appearance of the glass is not the first wife, glass scraps marked, so your results carefully selected cars have had the car accident (this is not never happened.) Add that I think the dealer a small scratch can handle basically perfect, not very careful observation can not tell, but an accident such as the injured tire, as long as the dealers do not change to impossible to repair, so I will focus on the place In the tire, and sure enough, the dealer strongly recommended to me in the hall of the right front tire of a car the size of a peanut break,
monster beats by dre, the car will not be considered immediately, it is estimated the car's tires have been replaced today.
Step Seven: Check the cockpit
you into the cockpit at this time is the time, dealers say, one can not wait to see into the cockpit to pick up the car to know that a novice! Fear that a long time around the machine does not turn into the cockpit. There is also nothing to say, against the manual inspection of various buttons, switches are all valid. Lighting, sound, air conditioning, seats, seat belts, electric windows and so on adjustment, to take the trouble of a first test. Do not listen to dealers, they always tell you
We must carefully check the center console panel is an easy problem areas, dealer action is sometimes compared rude, do not pay attention to scratch the paint on the front panel off, I picked the second vehicle's right front panel there is a scratch,
monster beats dr dre, because at that time the car only two options, so I had to choose for a panel.
Step eight: Check the clutch and brake
here to emphasize that the selection of clutch and brake, as many dealers are not allowed to test, is almost impossible to pick only the seat of your pants:
1,
beats by dre studio, the cold car: step on the clutch gear hanging all,
monster beats, be sure to request the files are very smooth.
2, the cold car: step on the clutch hanging files, and then released the clutch and asked to pick file. Some stalls loose clutch pick was hard, which is between the cars and trucks to be compared.
3, hot car (many dealers do not allow car engines to pick hot car linked file, no matter, really insist!) Repeat the procedure 1.
4, hot car is not hanging files, hard on the brakes, be sure to tread carefully down the brake pedal feel the depth of change! Required times and the same depth, but do not touch the bottom, or is to be adjusted.
Step Nine: Transmission and travel system
proposed transmission must be the road test, especially in the 2,500-3,000 rpm stall speed into files should be very easy and accurate fishes, if they are best not to delay or require hard. Walking in the road test the system as long as the attention to listen to the sound reflector to find whether there are abnormal sound. Neutral ignition, the fuel door to the engine rpm at full scale 2 / 3. Experienced person to listen to sound out whether there is noise and resonance. Confirm the total size of the earthquake zone.
Well, if you really do according to these steps, can ensure your car is basically no big problem. Pick the car is to pay attention to your eyes, ears to hand to! See, listen, feel like more. But do not be heart to yo, an incredibly exciting up to finally have their own car feel, It would be bad!
