strange noise after changing serpentine belt

[jeffd34]

I just changed the serpentine belt on my 95 yj (2.5L) and now there is a whining sound from either the power sterring pully or the adjustment pully which is below the p.s pully. Is it possible its just too tight. How tight should the belt be? Will i do any damage if its too tight?

loosen it till the whining stops should be able to flex belt a bit to tight you get no flex good way to check if its to tight is if you cant spin alt pulley with out belt its to tight

Turns out it was the idler pully. I went to the local auto parts store which had one in stock. I had it changed in about 10 min. I then noticed a squeal from the power steering pully. Turns out it was low on ps fluid. Once it was topped off no more funky squeals or whines.

Don't mean to thread jack, but I am thinking about doing my belt. My current one looks ok, but the NAPA guy told me that they don't crack anymore, so he gave me this gauge to check the depth of the belt grooves. Anyone heard of this?

Well the belt I took off mine had cracks about 3/4 through the thickness of the belt. I still get a squeal till the jeep is warmed up. It goes away once its warmed up. I may take it to the local garage and have it looked over since its my daily driver.

good stuff. i drained all my fluid and filled it with this seems to react better now. but i wouldn't recommend if u live and drive in a cold clement its stiff "just a little" at first till the fluid warms up.
