right im chewing my way through aux belts far too often, about ever 3000 miles i need to replace the multi v aux belt, the edges are chewed and frayed and there are bits torn off from the v's, gotta the belt is on the wrong way round, its wearing tracks into a tensioner pulley that has no tracks, it was once flat, so im assumeing its on wrong way round, could someone post up a diagram of the correct belt routeing please
-
Check all the bearings in the accesories that the belt powers
-
just an alternator and a tensioner and the crankshaft pulley are on it and theyre all perfect last time i checked at last belt change, really bugs me, its not hard to put a belt on ever 3k, or even expensive, just a right pain in the tits
-
I hear you. Mine lasts a little over 3k. It's just the standard v belt though.
Is there any play in the alt shaft?
No WP or AC?
-
not last time i changed the belt, it was perfect, oh yea forgot about the water pump :oops: i think the belts on the wrong way, its wearing into the tensioner, its not groved for the belt, but the tensioner only has about 3/4mm from crankshaft pulley, i really dunno
-
This is an AAZ. Does it look anything like it?

the tensioner tightens CCW
-
that looks similar, not sure the tensioner is the same though or even there on mine, it tensions using the alternator i think, im not sure of the way mine is currently routed though
-
Oh that style... let me see
EDIT
like this?

engines like this should not be posted :!:
they make me droooool :P
-
Nah, I think that engine uses those new-fangled spark plug thingies...
However, it does look like it's gonna breathe some fresh life into someone's A1... :lol:
-
its the second one allright, and its routed the same way, why isnt the waterpump pulley groved, if it was it would probably last X3 as long, also, the belt squeeks after say a month for about a min afterstart up, i assume its slippinin on the alternator, if it was retentioned every month so it didnt get a chance to slip, would that help???
-
mine squeaks on me from startup. i've tensioned the belt as far as it can go too... i'm about ready to put another alternator that i have on it, and then rebuild the other one.
i usually have to rev the piss out of the motor to get the alternator to stop squealing. pretty annoying!!!

Time for a new belt as well sounds like, (pun intended).
-
The one I posted has an auto tensior. Basically there is a spring behind the alt bracket that pushes it out and keeps tension on it.
-
I'm sure any serpentine belt system is meant to have an automatic tensioner. Where the belt on the water pump pulley on gasser in the pics is wrong. tThat pulley is to have the belt run on it's back over it. Grooved pulleys = groove in the belt, flat pulleys= back [flat] side of the belt. Unless there is an adjustment on that alternator that can't be seen in the photo, how is it tensioned ? just by forcing the belt on???
-
to change the belt, you pry the alternator down from the top with a prybar then slip the belts over, retighten all bolts,
i thought the belt was on wrong too but, if it was surely the waterpump spinning backwords would make the car overheat? it has never had any problems with temperature with the belt on as the petrol engine above has. just shredding bloody belts too often

I can gaurantee you there is no way it came from the factory like that. Of course i could be wrong, but i have never seen any VW with that setup and i have never seen ANY vehicle where the serpentine belt would run the grooved side against a flat pulley. I wouldn't be too suprised that the water pump works anyways, because a diesel creates less heat that a gasser, but i thinbk you were just lucky.
-
ok, well i thought it couldnt be right either but, its been like that for over 6 or 8 years now, its always chewed belts and thats the way the belts have always been fitted.
whats the danger of me flipping it over and running the waterpump the other way? any permanent dammage besides possibly cooking th engine?
-
ive got a few motors with that belt set up and it is correct ive had no problems currently fitted to the aaz in my vanagon and no probs at all and it gets a hammering its done at least 50k and the belt is still ok.i always lock up to bolts after the spring has tensioned the belts and no probs.here in europe we have both types of belt setups and the tensioners on the first motor dont last as long and some ive seen have literally been falling apart but the later are always ok.
-
Here is some more info on the gasser engine I posted

vw really dropped the ball on that one, not groveing the waterpump, its dumb.
-
I just looked through both my Dayco and Gates manuals and there isn't one system listed that has a setup like that. I conceed that VW may have a system like what some of you are describing, but how can it not cause problems ? How it belt stretch compensated? Look what jtanquay said. Obviously the belt is slipping until it gets so hot that eventually grabs -just like a burnout. Blunt, i don't think you will ever stop having problems if you stay with that setup.
-
well Im not changeing the setup, Its the same as on all VW 1Y engine codes, and all ABF engine codes when you look into it so it obvioulsy works, no one else has problems, ill just retension the belt as soon as it starts to squeel, its only slackening one bolt and retightening it. thanks for everyones help though.
