In case your alternator decides to depart from its bracket, which is apparently a thing, you also lose the single belt that drives the water pump. Mine let go, and while I was getting intermittent high temp warnings, it was bouncing between 180 (normal) and 226, so I thought it was a bad sensor. My voltage alarm was set at 12.4 (which was just below what the old generator would maintain at idle), but my battery stayed above 12.6... so I ran 6 laps with no water pump. 3 weekend engine going back to Enterprises for rebuild. Looking at data, the alternator is consistently above 13.5 volts... so set your alarm somewhere around 13. Would have saved me.
