2010 Ford F-350 Super Duty Q&A
2010 Ford F-350 Super Duty Question: Loud howling or whistling/honking type sound coming from front dash area.
I have a loud howling or whistling/honking type sound coming from front dash area in my 2010 Ford F-350 Super Duty FX4, 6.4L V8 Diesel Turbo. It seems to be occur while traveling at speeds over 70 mph or in high front winds. I read a few posts of similar issues with Ford Explorers but nothing with F350’s. The suspected culprits on the Explorers were the Idle Air Control Valve (I.A.C), door weather stripping, side mirrors and windshield seal; but nothing definite. Has anyone else experienced the same issue? Has anyone been able to solve this very annoying situation? - moranke
Also EGR and PCV may make this noise. - your.mechanic
