Hi all, been a while since my last visit, mostly because this site has the strange tendency to make me want to spend money. :(
The LeSabre is doing great minus one small problem...
Every time now upon startup, I get a strange rhythmic squeak coming from the engine bay. I determined long ago it was definitely related to the serpentine belt, but I couldn't understand why seeing as how both the belt and the tensioner were brand new. In any event, my car slung a belt a while before this squeak started...I discovered that the idiots who changed my belt put a 938 instead of a 940 on. They agreed to change it for free, and all was well until this squeak started. It'* been getting progressively worse. Since it began and still now, it will go away after the engine has warmed up. I poked and prodded and found that if I push the belt tensioner pulley in towards the engine, the squeak stops. I'm worried that the small belt may have damaged my new tensioner, and may have been the reason for my last one failing. I tried tightening the bolt on the tensioner pulley but no help.
My question is, do you think this is a serious problem? The S10 has replaced the LeSabre as my daily driver, it'* now my weekend car...but it still sounds pretty crappy when I start it. How difficult is a belt tensioner to replace, if that is necessary? I'm at work now, so I'll try to fill in more details later but until then, thanks for your help.
More info: I loosened the belt from the tensioner, and spun it. It spun fine, no sqeaks, wobbles, or anything out of the ordinary. I even tried spraying WD-40 on the pulley hub but of course, that did nothing.
Well now I feel like I may have wasted your time...
This thread sounds a lot like my problem. The belt is offcenter on the pulley, not bad enough to slip but pretty bad. Would the pulley have been changed with the tensioner? It was just a standard AutoZone tensioner, though it cost an outrageous $73.
I'll check my pulley and get back to you.
Another problem: I have to take someone to the Atlanta airport (maybe a 200 mile round trip) on Thursday. Will my car safely make it there like this? Like I said, after the engine warms up it completely disappears...like there was no problem at all. It'* just in the first few minutes of running that it chirps.
