E-450 V-10 Noisy Belt

[jerzeyjoe]

I have a 2008 Jayco Greyhawk Ford E-450 V-10 ...the serpentine belt or tensioner/pulley is making noise... not quite a squeal... almost like a rapid ticking sound... made this sound since new... I have a little over 2K miles and thought it would go away... did have a Ford dealer look at it but they came up with nothing... I guess I will have to be a little more forceful with them... anyone else have a noisy belt?

We had a 1999 that had this issue from very early on. It was a bad idler assembly replaced under warranty.

Can you determine if it is the belt of the pulley? A bearing would normally be a low growl. Can you get a large screw driver safely onto the bearing or pulley bracket while it is running?

Also, do you have access to a stroboscope so that you can watch the belt while running?

I hate to use a belt dressing on a good belt, but you might try spraying a bit on the belt while running. Since the belt contacts on the flat side as well as the grooved side. there could be a bad spot in the belt on either side.

Thanks for the input Ken... don't have access to a strobe... did when I was working but retired now.....remember my Dad using a hose to his ear ...also a large screw driver as a listening device to locate engine noise... have rain today..might get troubleshoot it tomorrow..

Joe, just be very careful with the engine running and sticky anything around the fan an belt.

Better than belt dressing is dielectric grease. It doen't hurt the belt. In my case I had some rust on one of the idlers. Cleaned it as best I could and applied the dielectric as much as I could reach. Afer 100 miles the tick went away. Had a Ford mechanic tip me off to this. The RV sat for awhile and the idlers got a film of rust. Now I don't let it sit that long.
