ooooo bad~ have someone put a pressure tester on the cap and pump to 17 PSI and watch for where's the leak comin' from...hopefully is just a hose....but can see terrible scenarios....headgasket would be not a fun one...hopefully you didn't leave it run into the Hot zone....did not refill with COLD hose water thus cracking the block like an ice cube in a cocktail glass of whiskey~

get that plain water out of there and replace with 50/50 ethylene glycol/water...if these are aluminum heads you may be in serious trouble as aluminum wants to react and corrode....galvanically~
