[s-cars] Serpentine Belt

[Fred Munro]

Brian & Steve;

If you blow a serpentine belt, there's an even chance you'll take out the
timing belt with it. Some remnants of the s-belt end up under the timing
belt cover and if they happen to get between the t-belt and the pulley - say
good day to the t-belt and your valves. A local Audi tech warned me about
this problem and several listers have posted that failed s-belts broke their
t-belts.
Personally, I had a serpentine belt split in two along the length of the
belt. One half blew off and the other half stayed on the pulleys. I
retrieved most of the half that blew off from inside the timing belt cover -
beats me how it gets in there, the covers are pretty tight. Fortunately, the
t-belt remained intact.

Keep an eye on those s-belts & replace them if they are looking tired!

As to replacing it, I installed the new belt by removing the tensioner and
creatively routing and twisting the belt until it was in place. I took a set
of pics & intended to write up a how to but never got around to it. Now I
can't remember how I routed the dang thing, but it can be done and a few
minutes studying the problem should reveal the solution to you. Good luck!

When I was under my car changing the Samco hoses (glad I don't do that
change all the time) I found the serpentine belt looking very worn,
cracking all along the length of what I could see. I just ordered one
from Rod at the Parts Connection for $21, p/n 054-903-137B.

Now, I just have to figure out how to replace it. I'm sure there are
some tricks to doing it. I have Mr. Bentley for reference but any
pointers on this job would be helpful. Also, for future reference, is
there a scheduled replacement interval for the serpentine belt?

Thanks!

Just a heads up, and maybe a query as to anyone with similar
experiences...

The car is an S6 avant with about 98k on it.  I wasn't sure that the
t-belt hd been replaced by the PO; supposedly, but no records, and the
water pump occasionally sounded iffy, so I decided to do the service a
few months ago.  But, as traveling has kept that from happening, I
finally just dropped it off with Keith at Crescent City to have Charlie
do it.  Glad I did.  Apparently the crank bolt was hell to remove, but
he scariest thing ws that they found the serpentine belt losing chunks
of rubber.  What is the life expentancy of that belt?  Although the
t-belt looked like it had been replaced relatively recently, I would
have thought that any problems with the s-belt could have/should have
been seen back then, or does it happen really suddenly?  Any experiences
down that line?

Feelin' lucky I decided to change the t-belt...
