Exclamation Pulleys / Tensioners Explained - But I Need Help !!! **1,400 miles trip *** PICS***

Hello Everyone

I am going on a trip to Arizona ( ASU ) in two weeks and i want to make sure my car is in tip top shape for 1400 miles. I need your help for my pulleys since they are running dry and making bad noises. i did a FULL cooling overhaul 2 months ago and everything went perfect so i doubt its waterpump . Except i ordered the wrong pulleys (which i still have in my room )

1- Here is the problem i got the pulley in the picture below which it turned out to be for hydraulic tensioner and i have a mechanical one for the main belt. my understanding is that i have to get a whole brand new mechanical tensioner since i can't just order the pulley itself. i however found a random pulley online which looks similar to the mechanical tensioner's pulley ( 2nd pic)

the one i ordered incorrectly


this is the one i think i needed for Mechanical pulley




2- i am confused which tensioner does my AC belt run on. i did not pay attention on this tensioner so it could be either of the 3 but i think it looked like the 2nd pic below. i have a 2004 330ci . which one should i get?


Mechanical


Not sure what this is called


hydraulic

HEY!!!!! I've got a mechanical tensioner for the serpentine belt, AND the A/C belt tensioner

Want to buy them? They're both unused because I bought the wrong parts for my car. I have a hydraulic tensioner and I accidentally bought an A/C tensioner for BMWs made after 9/2002.

They will both work on yours, and we live in the Bay Area, so no BS with paypal or shipping!

I replaced just the pulley on my mechanical tensioner with one I bought from Autozone. From what I recall, it was identical to the one in the second picture, and cost just under $30. It was sold under autozone's house brand, but labeled "Made In Germany," so obviously it's just rebranded bosch/lemforder/meyle/etc.

On my 2002 330, the a/c tensioner is mechanical and the main belt is hydraulic. My a/c tensioner pulley is like the second one you pictured. I believe you have to buy the unit new as a whole. ive never seen just the pulley itself. If anyone knows where to buy one, please let me know.

OP, use advanced search for me as author, and keywords "89133 mechanical INA" I just searched again yesterday for someone and copied my post from over a year ago on this.

You can get just the pulley for the mechanical tensioner...Dayco pulleys from Autozone. The PNs are in one of the few threads that will come up if you search...just posted yesterday, so go there first.

HTH...it should.

Op,

I recommend that u should just replace your mechanical tensioner with the hydraulic. The retrofit is easy and only requires a few additional parts such as a longer bolt and a few misc washer and such.

I had a mechanical but swapped out for the hydraulic.

Your AC is always mechanical.

I hope this helps

Thank you, D. I had never dealt with mechanical tensioners before. My 98 M3 had BOTH hydraulic tensioners. Why my 2002 E46 still had a mechanical on the AC is beyond me! When I did my cooling refresh, I wanted to replace my AC pulley but the mechanical pulley didn't fit. Strangely enough though, the pulley spinned perfectly and was actually very tight (felt new) I figure it has to do with that pulley being low to the ground and away from heat. It also does a very small job compared to the other two which get reamed with heat and pressure!

OK, so here is something i have been looking for - the AC tensioner pulley. Does this mean that this pulley could be replaced? He is listing 89133 twice for the main and the AC tensioner. I remember a thread a few weeks back we were arguing if one can take the pulley off the mechanic AC tensioner and replace it.
Anyone?

I can confirm that the Dayco 89133 pulley is an exact replacement for the pulleys on the E46 mechanical tensioners.
