Fanbelt noise driving me crazy!
My 97 F150 4x4 with the 4.6 has developed a fanbelt related squeek that is getting louder and driving me up the wall.
I changed the fanbelt a year or so ago. Two months ago I changed the idler pulley. It got better for a week. A month ago, I changed the tensioner and pulley. It quieted down for a couple days. I have loosened the belt. I cannot feel any abnormal looseness in the ps pump, alt, ac clutch, wp, or idlers. Ac on or off makes no difference. With the belt off, the alt is smooth, the ac clutch seems smooth, and the ps pump turns smoothly, and the wp and fan seem tight and smooth. Spraying it with water quiets it for a moment. I have doused the new tensioner with WD40. Spraying a ton of belt dressing seemed to make it quiet for a couple minutes. Any suggestions? Another new fanbelt? Thanks. |
well the belt dressing deal made a mess....
get a new belt get some carb cleaner and a rag and clean ALL the pulleys to get that crap off before installing the new belt belt dressing is the worst thing anyone can do it works at first but in the long run....your addicted if everything spins freely there is no reason for all the squealing unless something else was changed without the correct grooves in the pulleys somewhere down the line.... ...zap! |
ditto, clean that dressing crap off and see if thats the problem.

Been there done that get a new belt and all your worries and squealing will be gone. Belts wear out quick replace it and be amazed.
:thumbsup: |
My truck was sqeeking for awile.. Went out and bought a gatorback, before I could put it on the squeeking quit...lol

Thanks.
Yes the belt dressing made a mess. I tried it because I had some. It acutally made the noise louder. New fanbelt today. |
I don't believe it, but a new fanbelt fixed it.
The old one was less than a year old. I love quiet! |
