Serpentine Belt goes bad too soon.

Page 1 of 3  
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?

Buying a quality belt like a Goodyear Gator Back or Gates
check any car repair manual for routing of the belt over the pulleys.
Sounds like cheap quality issue to me.

Complete nonsense. Continental belts are the best there is. In fact, I'm pretty sure they are OE.

Made by the same company that made the O rings on the shuttle that blew up?
If they're so great, why are they falling apart like cheap Chinese Shite on this guy's vehicle? eh?
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 work.
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 failures.
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.

Are you jealous?

Well that's strike ONE! You've got 2 left.

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.

He said premature.

How do you know that * continental * belt isn't a Chinese counterfeit. Question me that, Batman.
There are even counterfeit bolts in our military aircraft, one reason the cobra was losing its' rotary wings early in its appearance.
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?

Oh, come ON! The space shuttle was a shitteaux design. Wouldnt have made any difference who made the o-rings on that doomed piece of shit.

Who, maybe not. Now if they'd been made of a material that didn't harden-up in freezing temps...
That is not to say its NOT a doomed piece-of-shit, though!

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 whatever else I can get, simply so that I dont have to take a lot of BS from people here IF I should ever have a failure;>) Now, if you put them on with a 48' pipe wrench, you may have a gasket failure.
The space shuttle seal ring was a different situation. No 'rubber' would have 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 band.

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.

The seal isn't the (biggest) weak points of the Fram filters. It's what's inside that is crappy.

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.

If your engine has a harmonic balancer and it is going bad, it can start eating one edge of the belt.

If it was a six cylinder model I would agree with you but I don't think there is a harmonic balancer on a four. 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.

It has been years since I've owned a Bimmer but I would think that a 4-cyl. would be far more likely to have a harmonic balancer than a 6, because of the 6-cyl. engine's better inherent balance.
