Makes a funny noise when it starts up in morning. Like high pitched scream. But only when its cold. Anybody else have this happen?
2011 Eco Screw 28000 miles on it. Never had any trouble this started after last oil change.

marines0811,

Have you been to your dealer to have them take a look? They'll be in the best position to get this diagnosed for you. If you still need a hand after that, let me know!

Mine when I start it will rev high to warm up. The higher revs cause the turbos to spool up. Probably just turbo noise bro.

My old F150 did that, but I would have thought they would have fixed that in the new trucks. It was a pretty well known problem with the belt tension pulley.
Symptoms that I had:
  • Loud high pitch squeal
  • Only lasted a second or two on cold days.
  • Did not occur on warm days.
  • Only happened at first start up of the day.
Pretty much what you described?



This guy shows a quick way to check serpentine belt noise. (Listen about 47 seconds in)

my 2011 screw with 50km did the same thing for maybe 2 minutes when cold, a lite off/on squeel. One of the pully bearings is the culprit nothing serious just add a small spit of wd40 on the bearings and dont over spray.
