Mine makes some clanking sounds after shutdown, but no bird calls for me

Its a Red Hawk....or maybe the ghost of one!
Mine has one too.....kakaw kakaw......
Good call !I think I heard someone say that DEF is pumped out of the line back to the reservoir at shut off to prevent freezing. Could that be a small pump dedicated to that action making the noise?
It’s normalGood call !
Yesterday I brought my 6.7 to the dealer for service and they duplicated the crow sounds... they stated it was the DEF pump returning the fluid to prevent freezing, and is normal.
Based on all the posts above - it's a DEF pump retuning fluid to prevent freeze-up. Sounds like many have it. I do not - but perhaps it's because I do not do too many short drives.Mine makes the noise as well consistently. Is repair needed ? Is this signs of impending failure? My truck only has 20k on the clock
Mine does it even after long drivesBased on all the posts above - it's a DEF pump retuning fluid to prevent freeze-up. Sounds like many have it. I do not - but perhaps it's because I do not do too many short drives.
Maybe it is a feature they added for the 2022s…Mine is very consistent as it does it EVERY time
Should make hunting a little easierMine does it as well, crows screaming after I shut it down!
LOL, I went pheasant hunting on Christmas Eve and parked at the top of an corn field eyebrow, shut truck off, then the infamous 3 crow squawks, which then sent every pheasant fleeing....sigh. My buddy just laughed. Pretty embarrassing on many fronts.Should make hunting a little easier
"Don't take our trucks hunting"LOL, I went pheasant hunting on Christmas Eve and parked at the top of an corn field eyebrow, shut truck off, then the infamous 3 crow squawks, which then sent every pheasant fleeing....sigh. My buddy just laughed. Pretty embarrassing on many fronts.
Mine does it warm or cold, and don't even need to start the truck, key on then off, and it squawks away. I was also told by the local Ford dealer service advisor this is normal operation and its a pump pushing DEF back into the DEF tank. WTH, couldn't Ford source a more quite pump! Good grief.
Maybe your pump is not working...It must not do it on all diesel trucks. I have had mine for almost 2 years and never heard the crow sounds from under my hood...
