2008 Tacoma problem. HELP w/ Vid

Just came back from vacation. Started my 08 Tacoma prerunner and it was making a whining noise coming from under the hood. I have a vid from the drivers seat.

 

Let me know what y'all think. Please help!

 

Have you pooped to hood or crawled under to try to isolate the problem?
I’d open the air box and have a look inside. Any time I hear “after sitting for days”.
I suspect rodents.

 

Sounds like a bearing on one of the pulleys or accessories. I had an alternator sound like that before (autozone junk).

I’d start by taking the belt off and spinning by hand and see if you can identify it.

 

Yeah that's kinda what I was thinking. I've never put any new pulleys or tensioners on the truck.

 

X2..
Taken from the FSM under troubleshooting engine noises at startup:

 

Agreed on the pulleys or alternator are my guess... TIFWIW

Had the alternator start going out in mine and probably sounded simliar.

 

Yeah that's what it was. My alternator was bad. Got it replaced now it's good to go.

 

sketchy online advice from people you don't know FTW!

 

That's right! This is a great place to find info.

 

Woo hoo! What did I win?

Glad you got it figured out.
