I seem to go through them every 12-18 months.  Usual failure mode for me is
the Temp gauge and A/C quit working. I never have seen low boost caused by
it. The last one was throwing false over-temps and no A/C. I knew the over
temps were false because I would start the car at 5 deg and in less than a
minute, an over-temp alarm. I don't think so!
