While driving the Cadi DTS, the temperature guage went to Hot and monitor said A/C is Off - this is the first time it's ever done this. I immediately stopped and opened hood and a belt on the drivers side was ripped off and wrapped around a fan and some of the belt was still connected. On the passengar side, coolant was spilling out from underneath the car. A friend looked at the car and said it was some pulley system but he wasn't familiar enough w/Cadillac to know the specifics. Have you heard of this problem or how to fix it?
