Is the automatic exhaust of car washing useful?

1. When installing the automatic bleeder valve on the radiator, tighten the valve core. After the radiator system runs, the radiator bleeder valve will be in an automatic bleeding state. Once gas is generated in the radiator, it will be automatically discharged from the bleeder valve. 2. When the radiator is installed and debugged or needs rapid exhaust, manually turn the hand wheel 45 ~ 90, and the gas will be exhausted from the steering wheel outlet. When the gas is exhausted, water will flow out of the air outlet. At this time, quickly turn the handwheel back and tighten it, and it will be in a state of automatic deflation.
