Suzuki: Car A/C coolant flushed out through coolant storage tank.how?why?, radiator cooling fan, radiator fan

Question
sir,
i have a Maruti 800 Euro II model (INDIA).
Today, a very strange incident happened (for the first time) with the AC fitted in my car.
while I had taken a halt for upto 4-5 minutes with my car AC switched on, the next moment i found the coolant being flushed out with pressure from the coolant storage tank which is fitted alongside the radiator.
I had also noticed that prior to this flushing out operation, the AC of my car had stopped cooling.
before i hit on to the service station, may i request you to guide me on this problem, and the possible remedies for the same.
i shall be greatfull to you.
cheers!

Answer
Does your vehicle have an electrically powered radiator fan?  It's entirely possible, and I suspect that there was a fuse "blown" which disabled the A/C, and subsequently disabled the radiator cooling fan, which caused overheating, and subsequent boil over of the cooling system.  This is all guessing, because I have never seen any of the models you refer to, and none of them are in the USA.
