FuzzFace2 Posted December 30, 2018 Share Posted December 30, 2018 Truck is a 81 F100 with a 300 six and factory AC. When I was replacing the condenser I pulled the hose off the old one that would go to the evap. When I got the hose off there was a orifice type thing in the condenser tube? It is not the orifice tube as that looks to be in the tube of the evap. So could that be a filter? It was clean. If so should I leave it in the new condenser? I will be using anew orifice tube, the old one looks clean also but going from R12 to 143a I should change it. The other question I have is with the compressor. The truck used the big ugly York compressor and I want to switch to the smaller Sedan compressor. I know they make bracket kits for this swap but what do you have to do for the hoses to hook up? I am guessing you cant use the hoses for the York and I am not sure if I can use the hoses from a later model truck as I don't know if they will hook to the condenser & evap. Any one know how this all works out? Thanks for any information you can give. Dave ---- Link to comment Share on other sites More sharing options...
85lebaront2 Posted December 30, 2018 Share Posted December 30, 2018 The brass piece in the hose is a quick connect. mine had them also. I suspect on the compressor a later pre-serpentine FS-6 will work they were still V-belt through 1986. Link to comment Share on other sites More sharing options...
Steve83 Posted December 30, 2018 Share Posted December 30, 2018 Your best move is to install a complete sealed charged working '94-97 refrigerant system (R134a, parallel-flow, & the later compressor), and figure out a bracket & clutch/pulley that will work on your engine. https://supermotors.net/getfile/994176/thumbnail/ac95b58.jpg Link to comment Share on other sites More sharing options...
Ford F834 Posted December 30, 2018 Share Posted December 30, 2018 When I ditched the York, I put in a compressor from a 1986 truck. The line from the condenser to the compressor still fit and worked, but the line from from the compressor to the evaporator was way different. I just ordered a hose for a 82-86 straight six truck from RockAuto that routes up by the firewall instead of across the front of the engine like the York.

FuzzFace2 Posted December 30, 2018 Author Share Posted December 30, 2018 I forgot 1 tinker thing and it may help others! Back a few months ago when checking the HVAC system at first I could got the doors to work I had no vacuum to the unit (see where I might be going with this?). After checking for supply and moving hoses around and plugging 1 I had vacuum to the HVAC controls. What did I take out of the picture you ask? The metal vacuum reserve can, looks like a small juice can. Yesterday I removed it from the truck to take a closer look and guess what the metal worms did to the metal can? Yep at the bottom on the front & rear ends, it lays on it's side, I found a little pin hole and digging I found it was a lot more than a pin hole. I removed the mounting bracket and also found some pin holes on the bottom side of the can. Now I could hit the junk yard for another metal or better yet a plastic one but my work hours and when they are open don't line up so on to a fix. I sanded the area around the now gap at each end. 1 gap was pretty big so as a filler I used a pin used that you weld to body panels for pulling dents. I then mixed up a small batch of fiber glass rosin and used it to fill the gaps & pin holes. I will add another coat or 2 and when happy will put the mount back on and install back in truck. So if your truck has AC and uses a metal vacuum reserve can, HVAC not working to good and you cant find that vacuum leak, look at the vacuum can.

I suspect on the compressor a later pre-serpentine FS-6 will work they were still V-belt through 1986. It is not a brass piece, I will have to get a picture of the parts next to the orifice tube. As a guess I would say it is a filter just never seen one in a system before. Dave ---- Link to comment Share on other sites More sharing options...

I also just installed a new condenser. Now what would have helped on the install is that hood latch bracket. I had to space mine out to clear the condenser. I am still working on getting the compressor brackets so at this point I can go either way on the compressor. I have also looked into making my own hoses for the compressor if I use the sedan. Just checking the options I have at this point. Thanks Dave ---- Link to comment Share on other sites More sharing options...

I just ordered a hose for a 82-86 straight six truck from RockAuto that routes up by the firewall instead of across the front of the engine like the York. A week or so back I was looking for AC hoses and not a lot showed up but I was looking for my year 81 with a 300. I will check both the compressor & hose for the later 82-86 trucks. I have also looked into making my own hoses. Between the hose kit & crimp tool would be about what I think a shop would charge to make them. Just looking over my options right now but with out compressor brackets it is all for nothing. Thanks Dave ---- Link to comment Share on other sites More sharing options...

Thanks Dave ---- Dave, you will have a set of the ‘83-86 style brackets headed your way early in the week. The compressor hoses should be readily available, and not terribly expensive. The one other thing you might still need is the pig tail that plugs into the later style compressor. I may have one, I will dig around and see...

Steve83 Posted December 30, 2018 Share Posted December 30, 2018 Well that is not going to happen as I have the HVAC box, after cleaning and dash back in the truck.The in-dash box can stay; only the underhood box has to be changed to use the factory '94-96 evaporator. https://supermotors.net/getfile/978974/thumbnail/evaps.jpg https://supermotors.net/getfile/1089927/thumbnail/evapcovers.jpg And it's pretty easy to change, even when the truck is assembled & driveable. I've done the swap without losing any coolant or refrigerant.I also just installed a new condenser.Sucks, but the factory parallel-flow condenser is vastly superior, and a worthwhile upgrade to any older system. Especially if you can find a complete JY system locally. https://supermotors.net/getfile/967466/thumbnail/29hood.jpg...I will have to get a picture of the parts next to the orifice tube. As a guess I would say it is a filter just never seen one in a system before.Is it the conglomeration of fittings in this pic where the "liquid line" pointer is? https://supermotors.net/getfile/931420/thumbnail/ac49.jpg Link to comment Share on other sites More sharing options...
