I was just putting my car down for the winter
and i let it run so the fuel could burn away.
When i returned to my car my coolant, WAS BOILING AND WAY ABOVE THE FULL HOT LINE. heh.
Anyone? Doesnt make sense to me.. anyway,
in my overflow tank(is that what its called?), i had a bottle shoved in there because the cap went missing, when i popped my hood, the **** was spraying everywhere.. is it corrosive? FLAMMABLE?
What should worry about/do? As i type this the coolant
is still bubbling and boiling in the overflow tank. Help, Quick, PLEASE. thanks.

 

I wouldn't worry so much about the coolent just rinse it off then dry, I would be more concerned with why the car got that hot to begin with. No guess here, but that would be my concern, seeing that I would probably forget it did that next spring when the car is back on the road and the weather is warmer.

 

Well.. all my coolant is gone out of the tank it was boiling in, now that its cooled off, so.. maybe there wasnt enough coolant and it got REALLY hot?
But then again, maybe all the coolant that was in there in the first place is all over the driveway.

Any other reasons this could happen and things i can do/check? thanks.
