It is likely just reaching the pressure limit at 1.2 bar and bleeding off properly from around the inner lip of cap. You may be overfilled, or having overheat problem from a bad impeller. Or if you are running Evans, you should allow for more expansion compared to water coolants, and fill to 3/4" less on quad bottle --any overflow should stabilize and stop at a safe coolant level.
