Dealer A/C Question
Having successfully fixed the heat on my '80 F-150 (300 engine), my next project is to fix the (dealer-installed) air conditioning - hopefully in time for the warm season. My question concerns the differences between my old and new compressors.
The old compressor has blocks bolted to the top of the housing for the hoses, which are attached via hose clamps:
My new compressor, however, has threaded ports integrated with the housing:
I am operating under the assumption that the only thing this means is that I will need to source pre-made hoses with the appropriate fittings. Is this correct? The only other difference between my old and new compressors is that the new one has only a single-belt pulley - I'm assuming I can transfer the pulley from the old compressor to the new.

So after I posted the above it occurred to me that maybe I should use my brain, and go look up my new compressor on the NAPA website. Sure enough, it's listed there as a replacement for FACTORY air, not dealer air.
Is there any way to use this with my dealer air setup, or do I need to get it exchanged for a dealer-style compressor? The reason I ask is that the return process will be a little more complicated than usual, given that I got it from my brother, who got it from his buddy who gets a discount at the parts house...and they're all 60 miles from here anyway.

Best bet, is to get the correct item. You could convert everything over to use that comp, but with the extra cost and effort, it wouldn't be worth the trouble. Especially if the replacement was bad.......

You might exchange the inlet/outlet fittings between the two pumps. Will likely involve some seals but that might be easier.
I would remove the fittings from the old pump, it looks like there are two bolts holding each one on, see what kind of seals are there. It's hard to see your new pump exactly in those pictures but I would imagine the parts would be interchangeable.

NumberDummy, thanks for looking those parts up for me. As it turns out NAPA sells a new compressor for this application, and I just got the word from my brother that I can do a one-for-one swap with the incorrect compressor that I have. So I'll have my new new compressor next week - but I appreciate the pointer to another source nonetheless.

I was able to swap the compressor I had for the correct one, with no hassles due to the oddball acquisition process. So far, so good.
Now...where do I get new hoses for the thing? I'd like to replace all of the 30+ year old A/C hoses with new ones, but where do I get them from? I've checked several major parts chains (NAPA, AutoZone, Advance) as well as LMC and NPD, and nobody seems to have hoses for dealer air. Factory air, yes, but not dealer.
Some of these hoses are just hose that I can probably get anywhere, but some have unique fittings. Am I going to have to get these custom made? Surely *someone* out there sells them.

I'd go and get them made if they are bad. Some select o'riley stores for instance can make them for you from scratch.

That's what I'm afraid I might have to do. Do you know if they can typically procure new fittings, or do they need to reuse my old ones? Can old hose fittings even be reused safely?

There are no "fittings" with dealer installed air. It is just pieces of hose cut to length. They slip onto the hose barbs and get a hose clamp around them, just line in your picture. I had new hoses made for my dealer air '82 years ago. A local parts store made them for me. They just pulled the roll of hose off the shelf and cut me the pieces that I needed.

Dorsai, if you have a good independent AC shop in your area, they may be able to come up with the fittings or service valves you need. Most of the dealer installed stuff I used to see had service valves on the compressor. Most of my older Ford factory stuff just had hoses to pipes that went right on the compressor head. The last Ford I had with a York or Tecumseh compressor was my 77 F150.

Not strictly true, at least not in my truck. The hoses in the engine compartment are as you describe...but the hose that attaches to the expansion valve under the dash has a fitting. That may be the only one...I haven't pulled all the hoses yet to be certain. I suspect the other hose that comes into the cabin has a fitting as well.

If only I had a time machine to go back to 1980 and warn my grandfather to buy the factory air option...

OK, so instead of cluttering up other peoples' threads with my random questions, I'll clutter up my own...
I'm pretty much ready to go on the A/C. I've got my new (correct) compressor, new hoses, a new drier. I'm going to keep my existing evaporator, condenser, and expansion valve, since (a) I have no reason to believe they're bad, and (b) some of them are a bitch to remove.
So, questions:

So, questions:
- How much oil do I need for the system? My compressor is new, but because I got it as a swap for my old one with some amount of unknown shenanigans going on, I don't have a manual for it. It's a Climate Control Inc. model EF-210R, obtained through NAPA. I can't find anything online that unambiguously gives the oil quantity.
- I took the tape off one of the ends of my drier a couple of months ago to check the port size. Being a big dummy, I didn't realize that the tape was there to keep the unit sealed, not just to protect the port. So now the dryer, with its load of dessicant, has been sitting partially open in my garage for months. Is it likely to be saturated, and therefore dead? Do I need a new one?
