That thing in front of your rad is the condensor used for the A/C.
If you have removed all the stuff you can remove it.
You need a non A/C bracket if you are going to run it with out the compressor now.
I may have one but I wont be able to check till tomorrow or the weekend.

It depends on what generation of vehicle you have.
Mk3s Don't require any new brackets that I'm aware of, just a smaller belt.
Mk2s don't require the actual bracket to be replaced, only the alt and the "arms" that allow for adjustability between the bracket and the alternator.
Another option for the mk2 is to just delete the compressor and then get a different pulley and run a really long belt. This isn't recommended though
MK1s I'm not sure as I've never seen a AC setup
Basically pull whatever is connected to the AC out. Make sure that the rad fan still works. Depending on how it's wired for your year car with the AC shiz ripped out the fan might not come on at all

When my 90amp altenator in my 91 finally went I removed the AC compressor and found I had to go to a 60amp altenator due to the bracket setup as I did not have the proper adjuster to tension the 90amp altenator without the compressor pulley in the mix. The 60amp altenator is above the pivot and the 90 amp is below (as far as I can remember) this caused serious issues.
I am having a hard time keeping belt tension with my setup and really miss the 90amp altenator. I may try to adapt a tenstioner pulley from a newer model with serpentine belt to work with the v belt and see if that will keep the belt from slipping.
I have not had any issues with fan operation, however I left all the original wiring where it was. I have yet to replace the air selector with the non-ac one but there is wiring attached to it as well to control the fan operation on the A2.

Oh my 80 diesel there was A/C but when the compressor was removed there was no need to replace any mounting brackets
Just needed a shorter belt... maybe some others had to change the bracket? So check into your bay because I know some freinds had to...
I guess it depends on the model or? So many small details...

my 84 Rabbit diesel was a non A/C car. the non air bracket is lost in my parts piles. on a search and rescue mission now, but no luck finding yet.

you can use a switch(more work though) or wire in an automatic switch they have them at schucks

Ive been told this isnt the way to go.... Anyone had a switch wired into there rad fan and forgot about turning it on?
Ive heard of freinds blowing out there hoses because they forgot that shiz
So in removing the A/c you just need to pull everything that connects to the condensor....What do these tubes lead to that go into the firewall from the engine bay? A/c related tubes....of some sort!

Tell you what, I'll likely take everything you don't need for the A/C, because I am doing the reverse of what you are. :lol:
I've got a '95 Jetta body with a 2.0L ABA gas engine and an auto transmission that I'm going to be putting my '94 AAZ with a 5-speed in. The transplant body already has AC, so I just need the additional brackets and stuff as well as the AC-model serpentine belt to drive it.
PM me - I won't be doing the swap for another couple of months, so I'm not likely able to give you the missing parts in a timeframe that works for you, but I'll want to buy or trade for the brackets and stuff for my own swap. Thanks!

The pipes that go through the firewall,
on the passenger side, go to the heater
box. Inside the heater box is the
evaporator (I think it's called). It looks
like a small rad. (about 8" X 9" or something).
You can just cut those pipes off, but you'd
probably be better to just look for a non a/c
heater box and replace the one in the car.
If you remove the a/c heater box, you'll
find a drain pipe underneath it around the
middle of the "hump".
You can pull out the plastic pipe and plug
the hole. Otherwise vast numbers of mice
will get into your car and abscond to Mexico
with it.

I've removed two AC systems. I used 60 amp alternators on the existing bracket because its the easiest way to go ( especially if you have parts cars
)
You can use the 90 amp alt if you fabricate a tensioning arm.
I used a pair of bolt croppers and cut the tubes and pipes where ever to facilitate easy removal. As far as the pipes through the fire wall, cut them close to the fitting and forget about it .
In both cases the only issue I had with the radiator fan was the fact it would switch on if the heat selector lever was in an AC position. Probably what its supposed to do but one last niggling vestige!
