Re: Serpentine belt squeaking
 

Belts get polished up and go bad. Mud, aka liquid sand paper is good
for that. I eat 3 or more belts a year when mud running.

Hey the belt is still tight and looks good, it just won't grab anymore.

I test mine by trying to hand slip the alternator pulley when cold and
off. if I can make it slip by hand, it will slip under load.

Re: Serpentine belt squeaking
 

Thanks Bob
My understanding is the purpose of the automatic tensioner is to eliminate
manual adjustments down the road. Unfortunately if the auto tensioner has
already compensated for any "stretch" and the indicator has not reached the
"II" mark, then there is no way to increase tension except to replace the
belt or tensioner if worn. The old manual tensioners sounds more versatile
as it appears a nut and bolt maintain the tension. These automatic
tensioners rely on springs that often themselves lose their strength. I
wish it was as easy as using a Krikit gauge and manually increasing tension.
I cannot be the only one who has to live with this problem.

Re: Serpentine belt squeaking
 

Thanks Mike
I am afraid you are right! Although my belt looks taut and free of wear,
thanks to road debris I now have the beginnings of what is a typical "glaze"
issue where the belt will not "grab". I see you go through 3 belts a
year!!! I have read from numerous sources that belt conditioner must never
be used on Serp belts and also read there is nothing to date to eliminate
"glazing" on a belt. There must be something out there to offset replacing
belts three times a year on the newer TJs, esp if we do mud a lot. A
goldmine here for an inventor??
