DodgeForum.com - 95 Caravan Frost Plug

Hello I Have A 95 Caravan and as i was driving it down the road my temp gauge stared to move to hot rather quickly and a little steam comeing from the hood.So i continued on around the corner to stop and look under the hood,When i did i saw a lot of steam and my temp gauge went straight to the hot.so my house was just down the street and i made it there ok .So i thought id let it sit for a cupple hours and i'd try agan later so did that and when i came back out to the van there was a spot of antifreeze about as bit asw the van is.So i tryed to start it to get it to the garadge and it would turn over but it wouldnnt fire and right by the end of the moter andall the pullys and stuff it was leaking antifreeze badly!! So i was wandering if any one has ideas of what the problem is or how much it might cost to get fixed please email me back at moonchild4991@hotmail.com Thank you.:)
