I've been having trouble with premature belt failure for a while and can't
figure this out. The first belt that came with the car had a section of it
chipped off. The belt caused a knocking sound on the pulleys and was
removed. I'd checked the idler pulley and they spin smoothly. I'd installed
a new belt by the brand of Continental and it failed the same way (in the
California climate) as the first one only after a year. There is another brand
from the dealer which I should be using. The brand is BMW. I feel that
I've installed the belt incorrectly on this BMW 96 318ti. I made a simple
drawing of the belt configuration. What are some practical things I
should be doing?

That's two *continentals* in a row that self-destructed in no time on
this guy's car. PREMATURE belt failure. I've never known a Gates I
couldn't run over with a Caterpillar earth mover that wouldn't still
It's your money. But remember, the definition of insanity is DOING
THE SAME THING OVER AND OVER AGAIN AND EXPECTING A DIFFERENT RESULT.
Your a real genius, huh Larry? Let me guess... your some kind of a
marketing guy, aren't you?
So, let's see, one guy reports a relatively rare failure mode of a belt
occurring twice on one car and you attribute the failure to the belt
being defective. Don't you think there just might be some other
factor(s) involved specific to this particular car or driver? Not only
that, but the OP failed to state how many miles were involved in these
There are literally hundreds of thousands of similar BMWs running around
with the same belts in them and none of them seem to be having this kind
of thing happening, especially in such a short time, let alone twice on
the same car.
I would switch brands to see if that made a difference, wouldn't you?
After of course, looking at other factors like mis-aligned pulleys and
the normal things one looks at.
If there are, he didn't mention them. You can fabricate, invent,
fantasize that there are other factors, but that's YOUR fantasy. I'm
working off the information given in the report.

How do you know that * continental * belt isn't a Chinese counterfeit.

What's the big deal, Your Highness and most Excellent Diagnostician?
With the serpentine belt OFF, it takes a couple of minutes to check
for worn bearings and misaligned pulleys. Only an IDIOT would put
another belt on without checking for those things first.
Are you calling the OP an idiot?
WAS a shitteaux design? They're still flying the thing ya know.
Dude, there is such a thing as CRAP RUBBER. Have you never come
across this *stuff* before? I've got a Fram Oil Filter out in the
garage with CRAP RUBBER for a sealing gasket.
If you want a Sample of CRAP RUBBER send me your mailing address and
I'll try to get the gasket to you before Christmas.

And for how long has it been grounded? What's your definition of
"still flying?" <snork>
It's the Russians who have been going back and forth to the space
station thingy for the past 2 or 3 years.
Please read a newspaper now and again, there's a good chap. It might
help you to keep up. HTH. HAND, and all that.
Ive heard all the complaints against Fram, but used them for many years with
never a problem...ever. I have switched to Wix or Delco, or just about
else I can get, simply so that I dont have to take a lot of BS from people
I should ever have a failure;>) Now, if you put them on with a 48' pipe
you may have a gasket failure.
The space shuttle seal ring was a different situation. No 'rubber' would
stopped super hot exhaust from coming through there. If it were hot enough
to cut into the main fuel tank, no elastomer known to man can stand up to
direct exposure to those levels of temperature. The mechanical design, as
I remember the case, and the implementation of the assembly process led to
a damaged seal ring which then allowed plasma-like gas to escape.
Fram uses a _very_ low-grade gasket in comparison with that supplied
on the Mobil 1 series filters. In comparison, Fram's gasket ( and
other rubber parts ) is something between chewing gum and a rubber
There is such stuff as crap rubber. You know this from buying budget
tires and comparing the tread-wear and handling characteristics with a
higher quality tire. Crap rubber is not ruled out on my list, as a
case for premature belt failure. Other people have ruled it out and
gone on a witch hunt for something more sinister. Good for them; they
must have lots of extra time on their hands.
Absolutely, there are qualities and types of elastomers which are much
better than others for certain jobs. And they can age and ozone crack,
even when stored on a shelf in some dealership.
I havent bought a cheap set of tires since 1964, when I put a new set of
tires on my 57 Thunderbird for $50. Shortly after, I was goosegazing
at something, got too close to the car which was stopping in front of me,
threw on the brakes and slid into him Learned two lessons that day.
I replaced the original 5 year old 70,000 mile ones on my E39 a couple of
years ago - purely as a precaution, as the AC one was showing signs of
cracking. The replacements were Bosch so I assume OEM.
I had to have the waterpump replaced at a specialist I trust recently -
too cold to work in the street - and they reckoned they needed replacing
again. They kept the old ones for me, and the AC one had a deep crack at
right angles on both sides, and the main one was showing bad deterioration
on the ribbed side - chunks of ribbing missing.

All things need considering and the most unlikely is a faulty belt. Most
likely is a small piece of dirt stuck in the pulley V's somewhere. Even a
bit of rough paint would be enough. Then check alignment of pulleys and
condition of all bearings. Next check for mounting problems on the belt
driven accessories. Also check for undue drag or power consumption from
these. Last but very much not least, check that the tensioner spring is in
good order and that it is not weakened somehow. I have one engine now where
the spring is around half the strength it should be.
It is also easy on some applications to install the belt out of square. This
applies particularly if say the bottom pulley has more grooves than other
pulleys. Manufacturers sometimes standardise on crank pulley sizes but vary
the ancillary pulley and belt sizes according to application and load. In
this circumstance it is easy for the uninitiated to install a belt wrongly
causing undue stress and premature failure.
