AC R134 Conversion (Page 5/8)

I found several new 'kits' on Ebay, consisting of compressor, drier and orifice tube and including 8 oz of oil, for $202. You must pay attention to what pulley they have and also to the clutch harness connection. Autozone gets $181 for a rebuilt 4 Seasons, including the $10 core charge.

The 58255 has the wrong harness connection for the clutch unless the Fiero harness will plug into that pigtail. The parts houses couldn't tell me if it would or not so I opted for one that looked like what I took off. I also found that same new compressor on Ebay for $121.00.

It will work, the connector just looks different. It's still the two male spade terminals as the original Fiero clutch coil, just in a different form factor. The original wiring connector will plug into it fine.

Not knowing that cost me a bundle. I could have had everything new for less than I spent for a rebuilt compressor.

BTW, the variable orifice tube I got from AutoZone was a failure. It went so far into the housing that the installer couldn't pull it out. He had to pry it out, thus destroying it. We went back with a standard orifice tube and it works very well. $19.99 for the variable. Just a couple of bucks for the standard.

Does anyone know if the 87GT's came with "parallel" condensers? I saw a posting where the OP was concerned that flushing would not work on this type of condenser. I am making plans and gathering materials (flush kit, vacuum pump, seals, dryer, new compressor), and getting ready to work on it. I am already stretching the budget with the new compressor, but I really don't like surprises, like some element of the system that isn't flush-able.

That is good to know. The 58255 compressor is the one that I am going to get... based largely on your recommendation (thank you for that). I have all the parts I need queued up in a Rock Auto shopping cart, ready to go. I plan to source a compressor from Autozone locally, when I have confirmed the rest of the system is salvageable.

My condenser seems to be of the parallel variety, as suggested in another post (here). I don't really know, because I haven't taken it out and I have limited visibility of it in it's current location. I am still going to try flushing this guy, as I REALLY don't want to purchase a new one if I can help it (have already spent more money on repairs than I can afford ). I have an idea on how to close off the branch line temporarily during the flush, but I need to know how the lines are routed through the fins, to know if my idea has any hope of working. Does anyone have a diagram or cut-away showing how the flow goes???

Does anyone have a picture of a condenser from an 87 Fiero GT?

Well...

I couldn't find a picture of a condenser for my car, but I found some stuff in the Fiero SM....

This picture shows the hoses starting at the compressor



It is not exactly the same as what is on the 87GT, but I am guessing it will be close enough to guide me through this.

Here is a picture of the hoses and tubes at the front part of the car...Not really sure "where" this is, as I can't recognize any landmarks.



And here is a shot showing the hoses and tubes around the AC module.



Does anyone have anything they have put together showing all the connections??? I would like to make sure I am getting to all the connections, flushing every part and have the o-rings to seal everything back up when I am done.

Does anyone have a picture of the DA6 compressor right next to a new 4 Seasons 58255 compressor??? I am concerned about the depth from the mounting ears at the front. I have put in new headers from WCF, and I hoping someone will have the dimensions, images, or something that will tell me that the new compressor is either exactly the same depth (which may be a concern for the rear bracket) or slightly less (which would be a relief, and give the new header pipe some room).

Attempting to count up the hose/pipe connections in the A/C system:

1 - Connections at the compressor

2 - Connections at the firewall below the air cleaner

3 - Connections at he dryer

4 - Connections around the orifice

5 - Connections at the evaporator

6 - Connections at the condenser

Are there any connections or couplings that I missed?
