I notice a strange brrrrrrrp sound at idle or driving.
It's either coming from the radiator/upper rad hose, or from the k&n filter which I just recharged.
I have no issues with heat, it does not sound like water boiling or rushing through.
I did add some antifreeze last year when it was a little low. It visually looks ok, no oil ontop, no smoke from the exhaust.
I tried purging following "Ford Quick Tips #69: The Trick to Purging Air From Your Cooling System "

Seemed to help a bit but not sure if it was my filter being cleaned or that purge. Also squeezed upper rad hose to push some air bubbles.
Attached is the sound most evident at 1 and 4 second mark. They are short almost vibrating sounds, repeating every now and then.
Please let me know what you think this resembles, I don't know what else to troubleshoot
