UPDATE - The marvelous team at FoW (tech Richard Coppocia) succeeded in finding out the source of my a/c blowing 'warm' air following a recharge just several weeks ago, and why two earlier attempts at Ferrari of Stuttgart and Ferrari of New England for a/c service after being 'asleep' for many years failed to ever hold a charge. He found nothing wrong in the engine area - compressor, fittings, lines, etc.) and then took the leak detector to the area of the right front wheel where it sounded its alarm. Since the lines exit out of the right rocker area behind the wheel liner, he began removing the liner screws. All went well until he begain unscrewing one that unknownly had been screwed through the liner and directly into the low pressure line a/c line that was right up against the backside of the liner!!!As he was backing out this screw, it and the remaining freon shot out and gave him quite a scare! With the the ultra low miles, he was certain the panel had never been removed/replaced and that it had been done during assembly in 1989. They made a repair with a spice and union and two hours later a problem that has been this car since new (even with only 1900 total miles on it now) has been corrected. Certainly would have been a 'warranty' job if identified when new! Again, thanks to all those who contributed to my posting. I'm pleased to be keeping my 'original' compressor in the end! Stephen |

I have a good used (10-11k miles) compressor from my old 76 GTB. It's been sitting on a shelf for about 10 years, but turns fine. Anyone interested?

Thanks greatly to all those who replied to my inquiry. Ferrari of Washington gets the car tomorrow to do a thorough investigation and fix whatever needs to be done. Should it need a compressor, I'll opt for the rebuilt unit and have the original re-sealed at a later time as it and the car only have 1900 miles. Hopefully it will be something less intrusive. Thanks again, Stephen |

Just went thru this. The OEM compressor technically isn't a York, but a European made York look-alike. (Asperia?) I think even the internals are the same. If you get a York replacement, it will appear somewhat different. No big deal.
The pulley/clutch is different, but this is no biggy either, as you can just swap them.
My mechanic changed the seal on the front of my old compressor. Unfortunately, it's seeping again. If I have to do another R&R, I'll probably go with a Sanden compressor - search the Archives for details. |

hi,i removed my a/c compressor from my 328 only yesterday looking to tighten my alternator belt. It took all of 30 mins to remove,the most awkward bolt was the bottom 17 mil bolt,you see you have two brakets that hold the compressor in place the one on the right which has the ajuster on it,the second bracket on the left has the awkward bolt on the very bottom which you will need a small socket extension,the orhers can be undone with a normal pair of spanners(one in front one at back nut and bolts you see). All in al an easy job just a little crampt. hope this helps.C |

Stephen,
My 348 compressor front seal went bad about 3 months ago. On the 348 they are a Mechanical seal - the type with the ceramic mating surfaces.
I am sure that if you were to drop the unit into an A/C shop (and without telling them its for a Ferrari!) they should be able to do it no problem.
If you do it your self you will need a seal extraction tool
EPM in the USA http://www.epm.com/pg5.htm is a vast supplier of mechanical seals
Hope this helps
Paul

Bring in your old compressor to a auto store and have them match it up. You can get it from NAPA or Big A or PEP . All you need to do is remove your clutch assembly and put it on the new compressor. The Big A part # is 57066 and I used this in my 308. Don't know if the 328's are different. |

The compressors arent just an easy swap. Ferrari uses a 90 degree belt groove and everyone else uses a 60. the pulleys arent interchangable so I would have yours rebuilt |

Stephen,
Search the archives for a thread with 'york compressor' and 'r134a' in the test.
In it I posted pointers to a company that still makes the york style compressors for truck & marine use. There's a down-loadable service/rebuild manual, and they sell seal & rebuild kits.
This thread has a couple of tips on removing the compressor:

I remember writing up something even more detailed for someone about this time of year. Can't remember if it was last year, or 2001 tho. |

IMO, It's worth trying the seal first IF you are sure that the seal is what is leaking. Have someone charge it and leak test it to be sure. And replace that receiver/drier too before it gives you problems. The aftermarket rebuilt compressor will probably not look like the original one so if you concour your car, then try to repair the original compressor. |

I'd be interested too in hearing from anyone who has swapped out an a/c compressor on the 328. I'm a fairly good 'wrench' and might consider doing this myself. Any tech tips on removal would be appreciated. Thanks |

Opinions please - seems the front a/c compressor seal on my 89 328 GTB is most likely hosed - looses all Freon in a matter of several weeks. This is an ultra low mileage car whose a/c was not used for many, many years so this problem was suspected Recommendations please - reseal the original (anyone know where a 'seal kit' can be purchased for this York unit); or let the dealer install an aftermarket rebuilt ($300.00). The new one in the Ferrari box is $1200 - but in my way of thinking the one in my car is essentially 'new' except for the deteriorated seals. Thanks! |
