selected car must see, do not give profiteers kept the first step: to see the vehicle chassis and battery
you say, so what's good-looking car? Wrong, the new car is also leaking! Lay the body did not see the underground oil point, the chassis has no oil. Nothing can be more than a new car battery look, a look at the little window fittings and whether any green corrosion on the line. Note that the battery connector is usually loose, pulled away before JS must be tightened.
Step Two: Pull out the oil dipstick to see the color
people have to say, not all 0 km it? Of course, the But dealers bad yet, and some cars run many kilometers tory burch handbags, but the odometer is not connected, or more than ten kilometers, stunned posing is 0 km! Time to see the car turn off after three minutes, pull out the dipstick with a paper towel, black oil out. JS has also now know that, so even yesterday, when asked to inspect, even the dealer immediately highlighted the intention has been to prepare people to see is useless.
third step: listen to the engine sound
I usually drive to develop a habit, what kind of car as long as first love open the front cover open, the top end with a screwdriver in the engine on the other end of the top voice in the ear to listen, be accumulated experience of it. This hand-pick the car a big help, virtually eliminated half of the car, leaving the two. (Do not laugh! Pick essence of your car so be careful what is good, the more dealers you more seriously you can not slack!) Explain in detail here, so you can hear the engine sound is a noise inside, such as the rings sound , Knocking sound, valve beeps and so on. Good engine only a 'rattling' sound, no other noise. However, this method usually depends on the accumulated experience of conscious, one two that is not clear, in short, is to listen to some good cars. Wordy one: someone can help, should he step on the gas-liter engine speed you listen to the sound. And to block any rag he blocked exhaust, if the engine sound was changed and a few seconds to turn off the sink, is a good car! Otherwise where leakage. (I was blocking themselves, dealers do not look! Hehe.)
Step four: Start the engine speed at cold start table pointer when the attention changes
Under normal circumstances the pointer should be hit around 1600 rpm, and then slipped to 800 normal smooth turn (in northern winter outdoor inspection is down to 1200 rpm or so, after a few minutes to start getting hot car back to 800 rpm). Then observe the various instruments and warning devices are working properly, when the water temperature and oil pressure is normal, through the voice and reflect on the engine to check, first listen to the voice of idle should be smooth and continuous, there should be no metal percussion sound and other abnormal sound.
observed off the exhaust pipe smoke is normal, put his hand to feel the exhaust air outlet is continuous, the normal should be made of organic palm moist but not greasy, and then listen to the sound of the engine oil is slow continuous and any abnormal sound, and finally listen to the voice of hard acceleration and engine throttle to reflect on the accuracy and rapid, but also pay attention to slow and fast oil revenues when oil revenues to reflect the engine is clean, if any lag or speed whistle, should there is a problem. Throw the throttle (accelerator pedal to relax) idle is stable. Standing still, the engine speed to 3500 rpm if there will be a different roar.
Step 5: Check work
depends on the situation of each connection thread, if there shaking, etc. tory burch flats, that you are yourself, not much to say.
Step Six: look at the whole car look.
Some will say that you look at it when it looks ah? Of course, this is not the pick used car, look if there are scratches, this car does not stop there waiting for you to pick up, the dealer will deal with early in the morning, I want you to see the appearance of the door gap is not equal. In addition, the appearance when they pay attention to see the glass is not the first wife, glass scraps, marked, so that your results are carefully selected vehicles have had the car accident (which do not ever happened). Add that little scratch I think the dealer has been able to handle seamless, not very careful observation can not see, but incidents such as injuries to the tire, as long as the dealer does not change, it can not repair, so I will put the focus on the tires, and sure enough, the dealer strongly recommended to me in the halls of the right front tire of a car the size of a peanut break, the car will not be considered immediately, estimated the car's tires have been replaced today.
Step seven: Check the cockpit
this time is when you enter the cockpit, dealers say supra shoes tk, one could not wait to see into the cockpit to pick up the car to know is a novice! Fear that a long time do not turn around the machine into the cockpit. There is also nothing to say, facing a variety of manual check buttons, switches are all valid. Lighting, sound, air conditioning, seats, seat belts, electric windows and so on to adjust, to take the trouble of a test. Do not listen to the dealer, they always tell you rude, do not pay attention on the panel will scratch the paint off, I picked the right front panel of the second car had a scratch, because it was only two cars available, so I had to choose for a panel .
Eighth Step: Check 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 with feeling:
1, the cold car: slam the clutch gear hanging all, be sure to request the file is very smooth.
2, the cold car: slam the clutch linked to the file, and then release the clutch asked to pick files. Some stalls loose clutch pick was hard, which is between cars and trucks to contrast.
3, hot car (many car dealers are not allowed to pick hot car engine hanging files, whether he insisted to do so!) repeated the procedure.
4, hot car is not hanging files, hard on the brakes, the brake pedal must carefully understand the depth of change can step down! Required times and the same depth, but not touch the bottom, or is to be adjusted.
Step Nine: Transmission and walking
proposed transmission system must be a road test, especially when high-speed gear in 2500-3000 into the file transfer should be very easy and accurate fishes, if they are delayed best not to force or require. Walking in the road test of the system as long as they pay attention to when listening to the sound reflecting surface to find whether there is abnormal sound. Neutral ignition, the fuel door to the engine rpm to achieve full scale 2 / 3. Experience so that people listen to sound out whether there is noise and resonance. Confirmation of earthquake size.
Well, if you really do according to these steps, to ensure your car is basically no big problem. Pick the car to pay attention to is the eyes, ears, hands to! See more like touch and hear more. Centrosymmetric yo can do is, one up on incredibly excited, finally have their own car feeling, that may bad!
