Serpentine belt diagrams please?

Does anybody have the diagrams on how to change the timing chains on my car listed above it has the 3.6L V6 SFI DOHC 24V?

Thanks a lot.

My vehicle has noises from the engine area since early spring. Especially upon a cold start the engine has this zzzzzzzz sort of sound when climbing or accelerating. ATF and spark plug change did not fix it.
This video has all the noises. First ones sounds like belt noise. Later recordings are from the car accelerating, especially cold start:

Many thanks for any ideas you may have!

Thank you very much for the timely and informative reply, Joe! I have not done anything with the serpentine belt; the only reason I suspected it was reading of online posts, and the noise at idle. I try fix my own toys but I am very ignorant at this stage. Did you think the belt is any likely to be the culprit at all without considering my poor guess?

About noise when turning, generally no, except [1] I have heared the same noise as expected from accelerating, when turning left at intersections, but you know I had to press the accelerator in these cases:) [2] occasional squeaking from the steering wheel when I am frantically parking.

Tldr I did not find any correlation in that “ engine “noise and steering action.

The noise upon acceleration was worse earlier in the year when it was colder, but still shows occasionally now. (( Back then the engine power also felt inadequate simultaneously, hence the plug and ATF change at 150,000 km. Power issue was fixed but noise remained)). I drove to my mechanic 15,000 away one morning and by the time I reached him the noise was all gone.

Thanks Joe!
Today I went to local mechanics chain because the disassembly looks daunting to me. By the time I drove to the place (10-15 minutes) the noise was gone and after looking at it for an hour including test drive the mechanic found nothing and said "come back when it's actually noisy" (lol) and suspected one of the engine fixtures was loose.
Guess I'll have to wait for a cold morning with stethoscope.

Yes for sure, and my thanks for that!

Would you think it's the engine oil? It is not due for a change but it's dark brown, smell burnt a little, and only just reaches above the lowest of the three holes on the stick.

Is there a routing diagram for the serpentine belt?

How do I adjust power steering belt?

The alternator belt broke now cannot see how it goes on. It will not go on the very last pulley because the timing chain thing has a metal little plate hanging over. The belt will not fit under that. Do you have a picture of what pulleys it goes on? It is not a big belt.
