Really only hear it at idle, only heard it during accelerating for the first 3 days. That's gone, but idle noise is still present. Is this normal for the Kevlar belt?

It's common with the gates timing belt. I remember doing research because I was undecided between oem and gates. The belt may have also been over tensioned.

Common I would agree with, as I see it all over the place. Tensioned to just below spec at install to coincide with the stiffer belt. With how mild it is, can that be attributed to the Kevlar as I know the tension is right? Or may there be some other underlying issue?

i just redid my timing belt with a gates accessory and gates timing belt and i dont have any noise at all. they make noises if there to tight or to lose

But doesn't the tensioner take care of that? As it's hydraulic and automatic?

Eh the tensioner only does so much. when i did my timing belt i almost maxed out the idler pulley i beleive it was and then cranked over the motor about 3 times by hand and then set the auto tensioner. my auto tensioner only moved out of the pin about 2 or 3mm. i also changed the cam gears to hks but i dont think that would really make a difference

That sounds like the idler tensioners. The Gates makes no noise when installed with correct tension or good tensioner pulleys. I'd say one of the bearings is shot.

o yeah i didnt mention i bought a whole kit with the tensioners. i assumed that you did that lol so mr bradley is probably right

but it wasn't making any noise the install day before the belt? When installed, we put in a new timing belt, tension belt ( both Gates) and new tensioner.

I should have clarified. How you set tension will make a difference on if its quiet or not. We do 3-4 timing belt jobs a week during this time of year and use the Gates belt as it is the same as factory. We havent had belt whine in the 3.5 years I have been here that was the belt. Tensioner/Idler bearing issues or improper tension on cars brought to us by customers has always accounted for the whine.

no whine with mine.

Ok, can I adjust the tension to a little less without taking it all back apart?

Had Gates belt on previously. No whine

whine from the best actually quit today... haven't heard it yet. I'm pretty sure the belt was either a tiny bit too tight, and the tensioner took care of it, or it needed to be broken in a little bit.... in any event it stopped today.

HOWEVER............ now I hear a NEW noise. This one is coming from the back of the car, I have noticed it yesterday and today when parked and out of the car waiting for the turbo timer to kill the car. Someone help me figure this one out please. This is at driver's side rear tire.
