[urq] (re)installing A/C on an ur-q

Mon Aug 18 14:20:53 PDT 2008

 I'll stick with my normal statements...? The little York ain't sexy, but it is a very effective compressor when it is in good shape.? The worst part is when the case threads fail in the aluminum housing.? I don't know who is selling good York rebuilds, but I'm certain they are out there.? York is a very high profile manufacturer for A/C compressors in the commercial/industrial space.? They look just like ours, only bigger.

The best thing you can do for A/C performance is make sure everything is in the best condition possible.? If I were starting from scratch (and I will be some day) I would get the evap and con cores cleaned out.? Then make sure the fins are as straight as possible, to keep the airflow optimized so that the cores can do their jobs.? Put it all together with a new dryer when you're finished.

Chances are very good that you will have a solid performing system when you're done.? As a frame of reference, I bought an '86 Coupe GT for one of my kids a couple of years ago.? It had electrical issues causing the A/C to be inoperable.? After taking care of those issues, it has worked excellent... it is very cold.? I never even had to recharge it.

Mike - 

I think you and I talked - but I'll reply for the {hopeful] benefit of the
list.

I had the 2B bracket that mounted the alternator under the A/C compressor.
For some reason on my car it caused a loud siren effect.  Verified once when
we put the car on ramps and revved the motor - very clear siren coming from
the alternator fan.  I tried 3 different fans, even tried modding one.  No
worthwhile difference.  Alex Stickler has the bracket now - maybe he has had
better luck than I.  I did notice that 2B used it on their widebody car that
they brought to Urq25. I don't recall ever hearing the siren - then again I
didn't hear it run much - but I did hear it run and don't recall a noise
like I experienced...

My A/C system is bone stock save for a modified low pressure hose.  It works
"ok" now with R134 but do plan to convert back to R12 by next summer.  While
the mini york is not optimal - I know of several original systems that blow
very cold air - I'm convinced the ones that don't have issues - leaks, bad
valves, too much or too little refrigerant, something.  I like the idea of a
new better compressor - I feel like I heard somebody do this - but have no
details.  I wonder what is more of a PITA - getting this system to work well
or messing around with finding a good small rotary compressor, custom
bracketry and hoses, etc.  I wonder if a more modern (efficient) condenser
alone would help on this older system?  A/C experts? Dave D?

Well after the trip to Glenwood I have decided to

put back the A/C I removed. I am running a 944t

intercooler which required moving the alternator

to where the original A/C compressor lived. 

Talking with those that have BTDT with the 

2Bennett's bracket there were problems with the 

alternator surging. Has anyone used the bracket

and not had alternator noise?

I was also thinking of running a newer style 

compressor for weight and efficiency? Has anyone

done this, model, installation issues?

Thanks, Mike Hopton
