Aerostar Compressor Replacement & R134

joshhemming on Tue March 09, 2010 1:02 PM User is offline

Year: 1993
Make: Ford
Model: Aerostar
Engine Size: 3.0

The compressor on my 93 Aeorstar (no rear system) has locked up. I plan on buying a new or rebuilt compressor and clutch from or possibly AutoZone, installing it myself and having a local AC shop flush & charge the system. The system had R-12 but I'd like to convert it to R-134 at the same time.

Besides the new compressor & clutch, what other parts do I need to buy to facilitate the conversion?

Any opinions on the relative quality of ACKITS and AutoZone new and rebuilt compressors would be appreciated.

Since your compressor locked up, it can be assumed that it has introduced debris in the system. Since this happened the normal course of action is to replace the compressor, drier, orifice tube, and flush out all of the lines and condenser. For this model we actually have an upgraded Sanden compressor as opposed to a Visteon which is probably what you will find at Autozone. Since most places don't have the proper equipment to completely flush a condenser, I would recommend replacing it as well. If you are wanting to switch to R134a then I would recommend switching to a universal parallel flow condenser as well to improve heat transfer. As long as the condenser, lines and evap are properly flushing, I would recommend sticking with the R12 in the system. If you are looking for more information feel free to call us with any questions. 1-800-648-4475.

You can bet the R 12 compressor (FX15) sent a lot of junk thru the system, I agree that changing the condenser on those is a must, along with changing the accumulator, O tube and flush the rest.. Add back the proper amount of oil and recharge by weight of R12, if you're going to use R134a, then use either Pag 46 or BVA auto 100 oil.. can get you an FS10 replacement compressor along with all the other parts mentioned.. Do it right and you'll do it once...

Be sure you read this Black Death link. If you think you have it clean, Flush again.
