What is this noise? - YouTube

Maririnig ang tunog on the ff scenarios:
1) Cold Engine - Bagong start lang for the day
2) When I open the AC Thermostat and Fan
3) In the middle pag mainit na occasionally maririnig yung whirring sound pag inaapakan ung gas dahan dahan (Automatic)
4)After a couple of seconds mawawala na ung tunog pero sometimes maririnig mo din ang tunog pag lumiliko/cornering

Maaring belt. Pero I also have an issue with the axle boot may tagas/butas ata. posible bang nasa axle boot part na ung tumutunog?
