1 Answer


The "green water" is your coolant. You are just adding water, diluting your coolant. Apparently you have a leak somewhere and need to have it fixed. Could be a hose, expansion tank, water pump, engine block etc. The boiling and foaming is a symptom of the leak and a low coolant level. Have a mechanic inspect it ASAP, you don't want to overheat your engine causing more damage and being stranded on the side of the road.
