Noise with New Timing Belt/WP Kit
Greetings all,
At 16 years old and almost 33k I decided to do the Timing belt just to be safe. I ordered a Gates kit which included the Gates Belt, Aisin water Pump, Tensions and bearings that were the same name as the OE.
It seems that I am getting a strange whirring noise. I disconnected the accessory serpentine and it is still there. My cousin who is a fulltime Auto Tech says this is normal and that as it breaks in that it will quiet down. Its not loud at all but thought it was weird. I was a tech many years ago and have done tons of timing belts, mostly 4cyls and never heard of a break in period.
Here is a short video clip, let me know what you all think;

Yikes! That sounded awful. A metal on metal sliding-taping sound and I would have thought it was a bearing issue too. In fact, listening to your short audio clip, the first thing that crossed my mind was a bearing problem. But the whrrrrring sounds throws you off. Now after watching this new video it says something about the manufacturing process of belts. Wonder who actually makes the timing belts Toyota installs in their cars?

i installed an Aisin kit on my 2008 V6 Accord and it made some odd sounds for the first few days.
I really cannot tell anything from the OPs video...

Yeah I am torn on what to do. My cousin says is normal and will go away. He says he does them all the time and by the time they come back for an oil change it is normal. The Kit is a gates belt, Aisin WP, Koyo bearings/tensioner.
The idler pulley was nice and tight and smooth, the. Tensioner pulley/bearing had a little sound to it, almost like a skate board wheel, i was told that it was fine and would break in. I may just rip it back apart, change the tensioner and TB to dealer parts for piece of mind, don’t have too much confidence that miles will make it go away.

That is classic "timing belt flutter" noise it will not cause any problems. It might go away after awhile or not at all, the fix is to immaculately clean the crank and cam gears of old timing belt material which tends to fuse to the teeth. And use an OEM or Mitsuboshi timing belt, or Dayco they are the quietest belts I've used. Gates belts are average quality at best the rubber is fairly hard and they are noisy.
