      Ok ive looked thru multiple post n seem alil lost I want to do a serp. Belt setup but I want to keep it all. Run my ac, power steering, and alt.

      if you want to use the serpertine base of mk3, you need a/c compressor and alternator of mk3.... i did this without a/c but with 16v alternator:

      you can use the mk3 pulley. but you need to have it machined down..

      don't machine down the mk3 pulley, it won't center cause the centering portion of the hub will be removed as a result. bbm sells a pulley for this with correct offset. now for the a/c part, what people said years ago was use either a g60 a/c compressor or have custom hoses made to use a mk3 one. dunno the truth on that a/c stuff, that was just stuff I heard and dunno if it will really work or not

      Ok thanks for that correction. Has anyone done the set up with ac n ps. Cuz seems like everyone likes to remove one or the other.

      if you swap your ac to a mk3 pump you'll have to change the lines too, find a rado g60 pump, i think theyre the same as mk2.

      to run the a/c you will have some clearance issues you will need to beat the front crossmember a bit

      no need to fit the different lines up to the mk3 compressor ( you can also have any a/c service shop make the lines for around $50 bucks or buy this

      this is the information i have collected over a few years now trying to accomplish the same.

      i have a passat 91 16v.

      crank pulley; if you go with the mk3 set-up; machine down the pulley 6mm; buy BBM piece( lots of money in my opinion)/ use 1.8t and space out; use TD ( canadian engine code AAZ) with chance for front keyway damage down the road. very comun issue with those. so then you can go with TDI harmonic balancer( right offset and belt thickness) but you have to modify your crank snout to fit the TDI harmonic and be done with it.

      to run all 4 accesories in one belt; a/c, p/s, alternator( go with a early TDI clutched pulley to help aliviate the chances of a crank snout breakage due to tensions on the oscilating mass at idle when the electrical load or a/c compressor come on) there is a guy in the passat b3/b4 forums from jamaica that made it work all in the same set-up. he made a custom pulley from a toyota and audi i think for the power steering pump.

      look up the thread name: family car turned project i think...

      or i am waiting on a new development where on another thread someone stated to replace the 4 cyl power steering pump with one form a 6 cylinder and that takes care of the offset and all at once. i have to see this further into details....

      the a/c compressor compatiblity issue: 93 is a year when vw revised the lines at the back of the compressor. they are the sa,me as a mk3 car.
      so a 93 passat 16v a.c lines will mate perfectly to a mk3 compressor.
      i do not know how the lines mate to the engine bay of any other car(mk2 or mk3). i have a passat 91 so the shape is the same to the chassis....

      good luck and let me know how you make out....

      SO... ALOT OF PPL DONT NOTICE THIS BUT : Did you know that you could unbolt the back of the compressor and put the back from the mk2 on the mk3 pump and use the SAME LINES???

      I guess maybe this could work. You would just need to flush the old compressors' R-134A if you're running R-12 like me. I guess I will just get an a/c compressor from the JY & swap my old MK2 unit backing. I guess I will be doing the swap a lot sooner, as I have been trying to contact a person for their G60 compressor, but he has not gotten back to me; this will be easier

      NOPE!!

      This will not work, I just got back from the JY & confirmed that the MK2 backing does not bolt up to the MK3 compressor

      the key to make this work; a 16v engine with serpentine belt and a/c is in the one year only of production when vw revised the lines and also in general terms the electrical connections through out the cars.

      i own a passat b3 so for me it is as easy as grabbing a 93 passat 16v a/c line from a junkyard car; and bolting it up to the mk3 a/c compressor.
      in 93 vw revised the style of a/c lines and they went from 2 individual connections on the back of the compressor top a single one like a mk3 car.
      again; i am a b3 guy so for me it is very easy to do that.

      the mk2 crowd does not have the luxury of a 93 model year car with a 16v so the lines for a/c have to be made or runs a g60 compressor like it has been said earlier on the thread...

      Hey guys, just trying to make sense of this for adapting the serpentine setup to the 2.0 16v, standard 9A block. I would love to get some clear consensus & maybe make a sticky because every time I look at doing this I end up more confused than when I started.

      This is with the idea that we use as many mk3 parts as possible because it's easy to find the stuff. Sourcing stuff from old diesels & G60's seems like the hard way to do it. There is also the benefit of replacing older parts with newer parts this way.

      Here's what I have:



      Crank pulley:

      - Take 5.5mm off stock ABA pulley
      - Don't use stock pulley because machining it would cause it not to be centered
      - 1.8T pulley w/spacer

      Which one is correct? I'm not looking at the pulley/crank so I'm assuming there is some sort of step or something that would go away if you machined it down? This doesn't really make sense to me, but like I said, I don't have it in front of me.

      The BBM pulley is $100 which is crazy. I would think you could get whatever machining done to keep the ABA pulley centered for less than $100!

      1.8T pulley would be spaced with a custom spacer from a machine shop? Would this not have centering problems as well?

      Concerns about sudden jolts from ps ac. etc. with everything on one belt don't make sense to me. It's all driving off the crank anyway, what's the difference. Having said that, I know my TDI has a clutch pulley on the alternator (because it exploded on a road trip). Is this really a valid concern?



      Block Bracket & Tensioner:

      - From ABA? We need to use the ABA bracket because we're using the tensioner, right? I'm assuming the tensioner wouldn't fit along with the mk2 bracket.

      - Water neck from ABA block



      Water pump:

      - mk3 with VR6 WP pulley? This allows the WP to run off of teh serpentine belt instead of teh v belt.



      Alternator:

      - mk3 with mk3 connector sliced into mk2 harness?



      AC:

      - '93 Passat lines might work, but it's not clear.
      - Existing mk2 lines will work if you modify the front crossmember to fit.



      Power Steering:

      - Mk3 PS pump with spacer or what? If I understand correctly, the 16v has a wider timing belt than the ABA which is teh source of these offset issues. So if you get a crank pulley that is moved in (however you do it) and use the mk3 bracket, everything should line up.



      Belt:

      - Depending on AC/no AC, PS/no PS, you just need the right length of belt. It would be nice to have some Gates numbers or something though.

      this winter i will have the oportunity to start puting together the engine for my sedan to be used next year.

      like i said earlier; i own a passat; so the chassis i will use this swaop into ; CAME from factory with lines that will connect to the back of a mk3 a/c compressor and will bolt up to the expantion valve on the engine side; passenger of the firewall area.

      so for my self:

      TD or TDI crank pulley. TDI pulley requires the notch to be made on the crank snout.

      clutched alternator pulley; vr6 water pump pu;l;ey on the 4 cyl water pump

      and FOR MY CASE ONLY; the mk3 a/c compressor with passat 93 model year ONLy; a/c lines to fit my car.
      as easy as that.

      on a side note; i changed the power steering pump on my 91 sean with one form a 93 passat 16v.
      the connection of the line at the pump is different.
      from thread in; to a banjo style; ala mk3
