I own a '96 GTS with 11,000 miles and have never had any issues with it until today. I drove it 10 miles and then stopped for an hour at my destination. As I slowly drove around a building at 5 mph I noticed that the power steering had gone out and it locked the steering wheel. I had to forcibly turn the steering wheel just to make the turn. I then started to drive home when the temperature light went off and the temperature was over 250 degrees for the first time. I was able to make it home and then the coolant overflowed onto my driveway. I let it sit for a couple of hours and then filled it up with coolant. My power steering fluid was just a little low so I topped it off. There was a quarter sized nonoil fluid stain under my car when I backed it out of the garage today. It was amber-colored. After the engine cooled off, I was able to determine that the power steering belt had come off the pulleys. I understand that this is a fairly common problem with '96 GTS's especially for loose pulleys. Is this a repair that an ASE Certified Mechanic can do or do I need to send it to the dealership? Any suggestions on whether this would be a good time to upgrade the pulleys etc?
