I have has a "clicking" noise in the auxiliary belt area , which up until today I thought was a bad bearing in my auxiliary drive belt pulley.

This afternoon I opened the hood with the engine running and noticed that the Auxiliary Belt Tensioner was moving as the belt rotated. I don't remember ever noticing any "noticeable" movements in the auxiliary drive belt tensioner.

Is this normal? Or is it my auxiliary drive belt tensioner that is going bad?

I am pretty handy - is this a difficult part to replace (would not think so).

Thanks

Just went out and started the engine and turned ac comp off.

Clicking noise dissipates and the movement in the tensioner reduced to almost nill.

Again - the noise is from either the tensioner of the auxiliary belt pulley belt below it.

Nathan,

This might help you..

Dealer recommended to me that I replace the serptine belt..after dealer installed the belt..i would hear screaching noise when it would be cold..

dealer recommended that belt tensioner was bad..I got that replaced too for $235..next day in cold weather ..the same sound started appearing..

turns out that the serptine belt that was replace was not routed correctly and a wrong belt was put on...apparently there is a bulletein that when replacing the belt ..it has to routed differently than the original belt..

I had kept the old tensioner and told the dealer to put it back and noise has never come back..

yes there was a little motion in the belt tensioner before i replace the belt..but dealer told me that belt tensioner usually don't go that fast..

so before you replace the tensioner..try replacing the belt with the right one..

i had 55000 miles on my car..

hope this helps..

Nathan,

Take the belt off and rotate & wiggle the pulleys around, feeling for play and "grittyness". They should both be very smooth with no play.
