4.6 Cold start ticking

I have a 2016 4.6 with 59k miles on it. In little less than a month on cold starts I can hear a ticking noise that lasted about 5 seconds in the morning near the radiator. I was thinking it could be the belt but I would like to hear everyone's else opinion?

 

Anyone else read this in one breath and monotone?

What type of ticking? Like from a lifter or plastic clicking?

Sounded more like a bit of a chirping noise. Maybe the belt or the idler pulley?

 

THATS WHAT I WAS THINKING TOO

 

My 5.7 started doing that bird chirping thing, started here and there and eventually would start doing it every time I drove and would sometimes get pretty loud and annoying.

I had the serpentine belt and tensioner pulley done a couple of days ago and so far it's been back to normal.
