Function:
-Effectively regulate the pressure and temperature in the radiator coolant reservoir and maintain the pressure balance of the system, prevents the car engine temperature from getting too high
-Rubber o-ring enables the screw to fit tightly in the radiator coolant tank opening, guaranteeing a good closure, preventing the liquid from leaking and the screw from loosening and falling off
