Fox cleaned the throttle valve (without sealing ring)

Don't worry, the sealing ring doesn't need to be taken off.

Cleaning is carried out with detergent, which is not corrosive.

And the sealing ring should be replaced every few years, and rubber products will age in a few years, so it doesn't matter.

I bought a set of tools, 20 yuan and detergent 7 yuan, and now I wash them myself, so I won't go to the 4S store. Too much trouble. Cleaning the throttle is actually very simple. After the warranty period, the landlord can wash it himself or find the nearest repair shop.
