My train of thought was this ; i know mixing red and green coolant can create a gel like substance, i assumed maybe possibly something like that happened causing increase pressure? Idk probably not, just a theory.

Ive had the car for a little while now (3-4 months) , havent experienced any issues with leaks or anything. Weird.

Gonna have it checked out in the morning. Hopefully its nothing major.

Edit : Yeah i agree, know heat of the moment, reading that this could potentially cost a boat load of money, tried to think of something more favorable. But after calming down, I highly doubt thats it because if it had caused a gel, there wouldnt be liquid everywhere.
