please help desperate. high pitch squeal wont go away!!!
I have a 2003 taurus 3.0 v6 vulcan. it makes this terrible squealing noise and is on the passenger side. i have replaced the alt, the belt. the crank shaft pully and harmonic balencer and idler pulley. it went away for a few days and then is back. should i change the belt tensioner. any suggestions please. i am desperate at this point.
Could be water pump bearings or the tensioner. Take off the serpentine belt and start without it. Do not run more than a minute or 2 and see if it is still there. If it is chirping check the Cam position sensor. If not check the tensioner and see if it has wobble or play in idler wheel or tension wheel. Then check the end play of the water pump, alt, and power steering pump.
Wish I could actually see and hear it in person. I am just throwing some random thoughts of what I would try. Good luck and let me know what up after you check it out.
thats what it sounds like but i am 100% positive its coming from the belt side. i iwll try to get a video uploaded so you guys can see. again thank you all for your help everyone is so nice on this forum.
