Ok whenever I'm taking off out of 1st gear my alternator belt squeals for a good 2 seconds then stops. It also squeals a shifting into 2nd. Could this be due to my sound system? I checked the belt and it is not too loose or too tight. I'm confused.

Also what size Optima yellow top battery would I get for my 2000 Civic Si?

 

anyone?

 

it could just be worn out even though it seems tight enough they are cheap and your probably over due anyway i would replace it and see if it fixed it

 

Your belts are going bad, replace them before the alt one snaps and you are stranded.

 

okay i have a brand new belt on mine and it still squeals like a b**** and this is on my ef but all the same... but yeah i will be driving and it seems to stop when the car is at 2800 rpms... but i will just be driving and with the stereo up and the hear this noise and turn the radio down wtf... everyone is looking at... so the stereo goes back up so i dont hear it... but yeah brand new belt and it now has proably 300 miles on it and it squels like hello

 

I jus put a brand new belt on and it still squeals. . . WTF???

 

the belt is probably too tight

 

my belt is only alternator hand pulled back tighten bolt...

 

did you apply belt lube/belt dressing when you put it on?

 

i did with out the dressing for a week... used the dressing still does it... so i determined that the dressing stuff is just a waste.. and it was the stp dressing
