squeaking

so every since it started raining in so cal
it has been giving some areas of oc with floods
since i have a lifted truck now and bigger tires
i decide hey why not drive through nothing bad can happen
after driving around and stuff
my belt starts to squeak
at first i thought it was my bearing or something
but as i poured water on the belt it would go away
is my belt dry or something
i have sprayed some belt dressing but that didnt help
should i go out and buy a new belt?
if so what brand cause i dont know what brand is good
at the stealership its 100 for the serpentine and thats wayyyy to much
any ideas to fix this?

 

$100 is way too much, the part costs less than $20 and takes 15 min. max to install. The hardest part is figuring out the routing with the new belt, but even that's not too bad with the help of the routing diagram.

Are you sure an idler pulley isn't seized? Or maybe catching every so often?

 

Good call, check the idler pulley. I'd probably pop the belt off it and see if it spins free and smooth.

 

idler pulley
so just pop the belt off and spin it myself
is that the one that you can move with a wrench or is that the tensioner
o yeah
every so often
it just starts to get really loud
and then not loud go away
and then when driving it comes back
always at idle
