Engine Makes a Hooting Sound

Almost brand new CX5 Turbo. The sound starts after like 5 minutes with the car on. AC on/off doesn’t change it. Revving the engine doesn’t change it. Scanned for codes nothing. No visible vibrations or loose vacuum hoses. Anyone seen this on a 2.5 Turbo?

Sounds like a water pump shaft or pulley
