Weird Sound . . . Do you know what it is?
 

UPDATE: Found out it is the idler pulley (it came apart some how).


Hi everyone,

I have looked everywhere for the answer to what this sound is:


I don't know if it is a belt since they usually squeal/squeak. Do you know?

I took it to Moab last weekend and it started after I climbed a hill called Scary Hill on the 3D trail (I beat it up pretty bad before that particular climb).

Thank you so much!

Thanks for the update.

And Welcome!

Thanks KingFisher. I went to the parts store and bought a new idler pulley and a serpentine belt. Replaced them both and now my XJ is back to normal.

Spark flying from the idler pulley at 0:18 sec! Definitely a bad pulley.

I think a new upper radiator hose is about $12 :icon_cheesygrin:

Thanks SuperRA . . . I didn't even see the spark. That explains all of the metal shavings and bearing parts in my engine compartment. I replaced the idler pulley and serpentine belt.

DFlinstone—does it look like I need a new radiator hose? My XJ is a lot like the Johnny Cash song where he takes one part of a Cadillac home at a time and builds a new car . . . except I am buying all my parts. $12 doesn't sound too bad.
