96 850 just got 3 days ago ac warm then cold , wont stay cold then tonight out of no where bam massive vapor pouring out of ac vents puddle of coolant on driver side and i think radio got sprayed.... all coolant out of over flow but engine temp good.... maybe core or evap any guess...? car was sitting few months before we got it also over 100 degrees today... but was about 80 when this happened

 

The heater core has failed. You need to get another one before you damage the motor (low coolant will cause the motor to over heat sooner than later). Check the DIY sticky for details.

 

i had it towed to shop an hour later that was something else i figured

 

Hopefully you have towing on your insurance and can get that $$$ back. Go through the New 850 Owner thread, maybe you can pick up a few things to avoid other problems that may be on the horizon.
