2014 3.5EB Rattlesnake
Hey all! Bought my 2014 SCREW XTR w/ 3.5EB two months ago. Last week I hear a noise somewhere behind the radio/vents upon startup: Sounds like a paper rattlesnake about 3 seconds after engine start and only lasts about 2 seconds, _with climate control off_, and only occurs on cold starts. Any idea wtf this is? I can’t hear it from outside with the hood up either...
Thanks for your time!

Sounds like you’re describing the dreaded Ecoboost timing chain rattle. Can you get a video of it and post it up?

I’m stumped! I can hear it but it DOES NOT sound like the timing chain issue to me. Hopefully someone will chime in with a different idea.

Yeah, it’s a puzzler! it reminds me of the chirp a climate system fan that needed replacing had in one of my old cars but the power is off at start up. Unless there may be a startup cycle of the fans, or something like that?
