If my coolant gage rises and then my car overheats, what is this indicative of? on 1993 Pontiac Bonneville

As soon as I turned on my heat, it worked, but then I heard several gun like shot sounds. After my car was parked for several days, I saw what seemed to be antifreeze leaking from my car. I put in water, but the coolant gage goes up rather quickly, then overheats with smoke.

Take it to a auto repair shop and get it checked! No way we can tell you what that is.
I intend to take it to my garage. Oh, Madonna, Mia! Thank you!
Youa welcome! Wish we could be more help.

WATER is NOT what the owners manual says to use. It boils WAY to easy. Hopefully your mechanic is told this info, and any other symptoms , for correct diagnosis. From your description , I wouldn't be suprised if it's blown headgaskets and or cracked cyl. head(s).Good luck.
