So I did a search on this already, didn't quite cover my questions.
I get a pretty bad rattling on cold start up, it goes away after 30 seconds and occasionally can be heard when I make abrupt acceleration. Only noticable in the colder months. You can see the pulley shaking quite a bit in the video below. 06 RSX auto 60k miles

I narrowed it down to the belt system. The indicator is right on the edge of the allowable limit, the indicator did not move/before or after starting the car which is when the FSM suggests to change out the auto-tensioner but I'm going to replace it just to be on the safe side.

My question is: I've been told the belt looks healthy (no cracks, no colour). How do I tell if my belt is overstretched or not?
I've looked at the OEM parts sites and they dont seem to carry the auto-tensioner. Where is a reputable place to buy one? What are some reputable brands? I see dayco and gates as common ones. Does someone have the exact part number?
Is it as simple as outlined in the FSM? I had a friend looked at it and he suggested I need to remove the motor mount to access the tensioner...that worries me a bit if true.
I have zero mechanical skills but I want to DIY this one.
Thanks.
