Strange Sound on Startup

[alakai66]

Aloha! I have a 97 SL2. I notice recently there is brief high speed spinning sound (sounds like steam escaping) coming from the belt area once the car starts. It started after driving for DoorDash making deliveries for extended periods, park overnight, then start the car the next day to that sound. It's so brief that I cannot isolate the location. Car runs fine, just that sound is concerning. Anyone else experienced this and how did you fix it? Mahalo!
