I called the belt company that I bought I from and left a message. S h i ty **** belt cost me over $100 in parts

 

The brand was Dayco

 

this is the idler pulley or the belts. either one or both. i have a 2006 G35 sedan 6mt with 10K miles on it. no bad weather or anything. i got the noise about one year ago. had it take to the dealer and the report said that the idler pulley (did not state which one) was worn and replaced.

noise came back 5 months later and they replaced the belts. both time noise was gone. it is back..so i think that the other pulley is gone. now i have to see which one. also could be loose belt. i will check. not as bad this time. but if it is a horrendous noise i bet it is the pulley bearing. the dealer said that they were bad.

thanks

john

p.s. all was warrenteed

 

I thought my idler pulley was bad but it was not (in my case) it was my aftermarket belt. look at ur belt and see if it says nissan on it.

 

I just replaced both belts with gatorbacks cause they were dry rotted and now I get the squeal only on cold starts. Never had it prior to the replacement. Will the dealer charge me to check the belts if i'm out of warranty?

 

its most likely the aftermarket belt

oh I remember those days lol

 

im having a problem with a loud noise during cold starts i only hear it when im driving and my car isnt fully warmed up . i replaced my belts a few monthes ago with oem nissan ones.as soon as my car is fully warmed up the noise goes away . i kinda think its comming from the intake but i have no idea

 

bearings are garbage. I just had to replace all 3 I/P bearings.. FWIW.

 

do you have OEM belts?

 

I have pretty much the exact problem as the op. Got my belts replaced, and my car squeals horribly after I start it up if it has been sitting for a few hours. Goes away after 10-15 seconds. I've read the entire thread, and there seems to be no consensus on the problem. I really don't want to spend a bunch of money at the stealership, but I have no clue what the problem is. This has been going on for months now, and I'm ready to get it fixed.

 

do you the have the OEM belts? it says Nissan on it, (in green color)

 

bump, so i didn't fix my problem yet but my friend fixed his he had the same problem as all of us. It was the idle pulley which was making noises. I will update when i will replace my idle pulley.

 

Aftermarket belts, especially quality ones, wont cause issues. Its all about proper tension. If its squeaking check out your idler pullies. Remove belts and spin the pullies. If operation is not smooth but you hear internal grinding in the pulley the bearing is bad.

If idler pullies are good then you just need to tighten the belts a little more. Do not over tighten or you will cause issues...

 

its all about the outside temp, I have OEM belts and when its really cold (less then 45 or so) it will squeak.
the best and only thing that helps is candle hold a candle under the belt and it will stop

 

its squeaking because your tension is off.
