I have a 2005 Tundra. I just replaced the serpentine belt last year with a Duralast (which my dad recommended) and now it's squealing again. I replaced the belt last year because it started squealing, then had no problems until now. Could this have something to do with the weather being dry? I live in bipolar Florida so one day it's warm then the next its cold. I have bought and applied belt dressing from Autozone, but it hasn't really worked. It works maybe for about a day, then starts squealing again the next. What should I do?
