Looks like the belt tensioner pulley is missing to me.

 

From what I see, nothing is missing. In the picture, to the right of the middle, lift the idler pulley, route the belt, release the idler pulley down (it has a heavy spring behind it) an that adds tension to keep the belt onto all the pulleys. You should have a diagram in front of the radiator of how it is to be ran.

Looking at it again, it does look like it's gone.

 

Agreed :

The diagram was an optional extra. LOL
Someone who shall remain nameless had a good idea, a couple of guys here got some made and sold them to people who wanted them, $5 extra to Canada.

 

See post #32 for what the tensioner should look like.

 

Look at post #3 , to see what it's suppose to look like.
I'm writing an your answering.

 

I supplied a link in post #44 that has the picture AND a price of $24.95.
What more can I do ?

 

Find him the pulley, that is what is broken apart, cheaper than the whole assembly. The tensioner on my NA had a cylinder on it as well. Never did look into its reason.

 

Never have seen the pulley listed separately for the NA.
That cylinder is found only on the 2004's, must have been something to do with harmonics in the belt,
at any rate they dropped it in 2005-

 

The pulley is out there, it is mentioned on this forum.

 

Thanks everyone for the awesome replies, So if I get just the pulley how easy to replace or if I get the whole assembly what will it cost. Looking at Rock Auto for the belt tensioner pulley and all shows a grooved one not the smooth one as shown in the posts here

 

Well will order this since it was new, rather than the used one that ala_xfire posted

 

Wise choice, didn't realize the one I posted was used. Need to wake up

 

Once again, you are correct. Found just the pulley in Hong Kong for $10 - ordered one.

 

It is a good idea to put the part number on the forum for all to see in the future.
I have some numbers but I am double checking them.

 

I will wait until it arrives and I can verify it is correct, then I'll post the link.

 

Now just in case something goes bad wrong, do you have a part number for the E12 Torx bolts? Trying to cover all bases

 

He has an ‘04.
Pulley 88mm OD x 17mm ID x 25mm wide. CLICK

 

My fairly early 2004 does not have the cylinder...
