Squeek after turning off? Help

2012 Tacoma base 2wd 4cyl.
When I turn off the ignition I get a loud squeek as the engine finally quits. I replaced the serpentine belt, but the condition still persists. No noises when the engine runs normally or driving. Any help would be appreciated. Thanks in advance.

 

Welcome to Tacoma World. You replaced the belt, but did you replace any idlers/tensioner pulleys or anthing like that? Any other info you can give us since we can't hear it? Very hard to diagnose mystery noises over the internet.

 

A video of this squeak would be nice

 

So I took off the serpentine belt and checked the pulleys in the system, they all are quiet and no associated play. Started the engine and turned it off without the belt and noise is still present. I am considering that this may be a motor mount issue possibly??!
115000 miles. Will try to get a video up. I travel a distance to work and want to prevent an issue.
