Noise on startup. Any concerns?

Although it can be a little fiddly, an inexpensive Krikit tension gauge will help you tension your belts to the factory spec.

For as cheap as the three belts are, might as well put a fresh set of new OEM belts on and save the old ones for spares.

So maybe under tensioned since the belts are only a few years old? Would that make sense that the sound goes away when its up to operating temp?

Like any belt they will stretch a little after a while and therefore be undertensioned hence new V old tension specs.
You can just nip them up a little or replace with new and keep as spares
Also as the motor gets warmer the rubber in the belts becomes more pliable hence the squeak lessening

glad the hose trick sorted out your issue too!

Thanks Charlie, thats a good idea. Thank you to everyone for your input. You have all been a big help. And robnicko, thanks again for solving this.

AC belt has made this exact noise occasionally off and on for several years. As soon as I watched your first video I knew that sound right away. Mine would do this on cold starts and then go away after just a few minutes. Usually tightening belts up to proper tension makes it go away for me, but the factory belt likes to stretch after a few years and cheap to replace. Glad it was nothing major.
