Help with Whistling noise

I just got the oil changed in my truck and the fuel system cleaned. But now I am hearing a loud and constant whistling noise. I think it may be the belt cause its the original, but i have no idea what else could be wrong please help

Sounds like a vacuum leak. Check to make sure all the little hoses are plugging in tight.

If you have a 4.0, check the IAT sensor.
