I didn't do this but when I got the runner it was set up with an electric fan cause the bearing had failed in the mechanical one.

Anyway I was wondering what anyone else running an electric fan uses for the alternator belt? A NAPA, or Carquest number or just what to ask for at the parts store? I don't want to have to take it off and go size it but I guess I can.

I was also wondering how do you guys alternators register at the dash? Mine stays at just under 18 all the time but it doesn't seem to be causing any problems. I am guessing this is because a difference in speed because of the missing pulley?

 

Take a string and measure around the pulleys. Then take it to napa, and tell them the measurement. All belts are arranged from smallest to largest by inches, which is incorporated into the part number.
