With the development of social needs, the market for second-hand cars is getting bigger and bigger, and the number of people buying second-hand cars is also increasing. How do we understand such a problem? Jinrui learned about the simple method of second-hand car inspection through detailed understanding, that is, checking the " on the car can determine the quality of a second-hand car. I hope it will be useful to everyone.
Small screws can identify the quality of second-hand cars, a very useful method:
2): tank frame screws
3): Engine Base Screws
1. In case of an accident, the longitudinal beam needs to be repaired (it is a big accident, and the front face of the car that hit the longitudinal beam is gone)
2. Engine maintenance or overhaul
3. Replace the machine foot pad
4): door screws
5): Screws for the trunk lid
If there is a rear-end collision accident, if the collision intensity is high, it will cause damage to the trunk cover. The trunk cover is very strong and must be removed and repaired. Small scratches do not need to be disassembled!!!
Here, the editor is teaching you that a good way to identify the good and bad of screw rust prevention is to look at the color. Generally speaking, the anti-rust function of screws is generally performed by galvanizing. China Standard Parts Network uses the understanding of screw knowledge to share the color of screws to distinguish the good or bad of screw anti-rust.
This kind is white zinc, and the anti-rust time is the shortest
This color is blue zinc, and the anti-rust time is better than that of white zinc
This is the one with the longest anti-rust time. The color looks a little shiny. It is generally called a zinc layer. The anti-rust time is the best. If you buy electrical appliances in the future, you can see the color of its screws. You can see the good and the bad.
