85lebaront2 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 I second Steve's opinion. The 1994-96/7 condensor will need a little effort to get it in and the 1994-96/6 A/C case is a bolt on and if you use the wiring hole in it you get rid of the underside A/C wiring. I will throw another option out for you, aftermarket compressor, Sanden makes a nice one along with a number of others. This will give you a higher volume R134a compressor. I have the Ford FS-10 on Darth but that was due to acquiring most of the HVAC system from a 1996 F150 the owner had rolled in broad daylight on a dry road (home grown sway bar system for his lift kit). I found a compressor hose set at Pick-n-Pull in Virginia Beach. The condensor is a new 1994-96/7 purchased from LKQ and fitted to the 1990 core support. I had already done an R134a conversion on Darth and our 1990 Lincoln Town Car so other than my konvertible everything we had was R134a. Link to comment Share on other sites More sharing options...
FuzzFace2 Posted December 30, 2018 Author Share Posted December 30, 2018 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... Jonathan, thank you let me know what you want for them and your trouble. How did you look up the hoses as I am sure I could not find them for my 81 or did you look up 83-86 parts? If so I wonder if the truck end of the hoses will work with the 81 system? Someone posted to swap over to the later system (full system) to get everything to match, not going to happen LOL Dave ---- Link to comment Share on other sites More sharing options...

I don’t think they have the hoses for the older York compressor system. Link to comment Share on other sites More sharing options...

The new condenser I have mounted in the truck is larger than the old one as I believe it is for 134a used in the later year 90's trucks and why it is not a direct bolt in. From what I have seen posted of 134a conversions in our trucks works pretty good using the factory parts so mine should too. Jonathan pointed out I can use the 83-86 hoses as that is when they also switched to the Sedan compressor but kept all the rest of the system the same. I want to get all the under hood work done (AC) before I put paint on the truck. Don't want to be leaning over freshly painted fenders to do the work! I do want to think everyone that has helped so.

Dave ---- Going to jump in with a question. On my 1992 Bronco, can I put a 1994 and up condenser in it? the A/C is adequate where I live, but hotter areas tax it. I think my 1986 system is better than my Bronco. Link to comment Share on other sites More sharing options...

On my 1992 Bronco, can I put a 1994 and up condenser in it? the A/C is adequate where I live, but hotter areas tax it. I think my 1986 system is better than my Bronco. I cant answer that question but if there is a junk yard with a 94 in it measure it and see how it mounts that do the same to yours. Now I am going to say if it does "bolt in" I cant see it working any better than what you have now. I say this because to cool that big old cave takes a lot of BTU's. That is why they put rear HVAC systems in larger SUV's and vans. Even my 02 Dodge Durango has a rear system and when not working as it should I can tell, both heat & AC.

Dave ---- I re-checked Rock Auto for the hoses and as Jonathan found if you go for the 83- truck they list all the hoses that fit the FS6 compressor, unlike the 80-82 York compressor hoses they only have 1 of. I did a little more looking into the 83-86 FS6 (sedan) compressor and what I found is unless you get a junk yard one, not recommended, they don't come with the suction or discharge manifolds. That is the little part the hose screws to that is bolted to the compressor. I spent a few hours with the truck parts CD's to try and find the part numbers and think they are: suction E1AZ 19E583-A discharge E1AZ 19E582-A Think they came with the bolts & gaskets. I will see where I can get them just in case they don't come with the compressor. Dave ---- Link to comment Share on other sites More sharing options...

Dave ---- That's what I was wondering. And yes I agree, I figured it was the size of the interior. My wife's Suburban is loaded, that rear A/C and heat is nice. Except for all the hoses and lines under the hood! It has hydroboost brakes too. Link to comment Share on other sites More sharing options...
