When I received the accessories from the original car owner when they were sorting out the warehouse, I found that there was an English-language sub-instrument panel. The original car had an icon, which did not look American enough. There is a slight difference between the fixing hole of the English board and the original car, and it can be installed with a little modification. By the way, the oil leakage of the booster pump is used to repair it. After a long time of research, it cannot be disassembled.
I had to use castor glue to fill up the leaking position, and see if it still leaks. The belts were all removed, and the bearings of the belt tensioner and the transition wheel were replaced with two imported 6203 ones.
Bearings are more expensive than accessories. Replace the belt and adjust the idle speed. There is basically no sound when idling. It is very good. I would like to thank the previous owner of Xiaoqie for his support!
