      Rookie questions from a new bimmer fan-

      1. What are the pros and cons of switching the low (white)and high
      (red) around so that the fan starts running at the lower temp?

      2. What is the normal range for the guage needle to be at? i.e not to
      be overly alarmed that is or when should you start to worry?

      3. What are the pros and cons of changing the low temp to 82C from 91C
      and the high to 91C from 98C when I get new switches? Any pointers on
      how to DIY the switches?

      Fantastic site.

      Many thanks
