I was driving home on the 110S interchange to the 105W last night when I downshifted hard into 3rd taking it to redline to pass someone. I noticed a weird abnormal persistent noise shortly afterwards but wasn't sure what it was. Shortly afterwards I noticed the battery indicator light came on but the car still had a normal amount of power, able to go 75-80mph without issue. I considered pulling over but I didn't want to do so on the freeway nor did I want to get off at any of the ghetto Inglewood exits. I decided to go another exit or two (1-2 more miles) taking the 405S interchange to Rosecrans. That was when I noticed the water temp in the very H range and kept it in more less neutral to cruise and limp off the freeway for another ~1 miles. That was when a whole bunch of other lights came on (traction control, check engine, etc) coming off the exit. Power steering went out, but I was still able to propel it forward into a strip mall area right off the freeway. Coolant was all over the engine bay. I used my iPhone light and I was able to see the accessory belt was no longer on (although the Rotrex supercharger belt was still okay). Then I called AAA to get it towed the last 4 miles into my garage. It is sitting in my garage now and I'm trying to figure out what to do for my next step. Any ideas where to start? I'm guessing the accessory belt slipped off after the hard downshift and the water pump no longer worked so that's why it overheated? I have another car I can use to get to work tomorrow so I do not need to rush it in for someone to look at because I don't know a mechanic who I'd bring it into for this type of application/problem. I'm running a Kraftwerks C30 kit and haven't had a problem until now after about 10k miles.
