I have a 90 ram w250 gas 5.9. It was missing its condenser when I purchased the truck. I went to buy one and all I can find are condensers that have a O-ring block manifold connection. My truck has hoses with female flare fittings, one from the compressor and one from the dryer. I did a little research and found these 2 different types were just a product of early production vs later, a rv2 vs Sanden compressor would dictate what line set you would have. Has anyone be able to find the correct condenser out there for this situation? Or an adapter block? I've had no luck and the closest I might be able to come is checking junkyards or finding a universal condenser, maybe.

 

I would look the parts up and get the oe part # then search. It may be obsolete/ not made any more. You could(if the lines are long enough) cut the old fitting off the end and have one that fits the available condenser put on. Or you may have to get a whole new hose made. Places that make hydraulic lines usually make ac lines also.

 

The RV2 was long out of production by the time your truck came out.
that's not what made the difference. RV2 also had a flat block type thing for hose connections.
nope you have aftermarket air conditioning. It was installed after the truck was built. Back in the day it was often called "dealer air" or " dealer installed air". As opposed to "factory air". My 83 had the same thing

Thats interesting, nothing about the system looks like an after thought! So with this being the case what would you recommend? Did you ever have to do any part hunting for you 83?

 

Thank you for that recommendation. I think I'm going to be stuck going that route.

 

Nope never dis have to find parts. Could be a sanden compressor or maybe even a York. There were aftermarket companies that made add on AC systems, finding the exact parts could prove futile
I have my 83 apart right now, stripped bare, and in for paint. Meanwhile between swap meets, marketplace eBay and plain old junkyards I've gotten everything for it that would have been there if it were to have come with ac from the factory. My son was the one who gutted the truck and I don't know how much of the dash stuff he kept. I know that engine and trans is in another vehicle (not even a truck) I have a different power train going back in. Can you show a pic of your dash controller

 

Thats good to hear you've been able to source things. As I continue to look im also seeing more options out there as it pertains to universal condensers and custom hoses. I also originally mispoke, I thought I had flare hose ends but they are actually female o-ring fittings, I believe #6 and #8. Which appears more common with condensers, so that's a relief. Here's my dash control:

 

Ok that looks like one used for factory air
that's weird as those years as I remember factory hoses were a flat flange with 2 lines and a stud in the center.

how long have you had the truck who knows what has been done to it from new to when you got it .. who knows what a past owner has cobbled together? As has been said there are places that will make up any hose you can imagine. And a lot of times they'll use universal hose barbs and hose clamps. Are your fitting crimped where they would connect to the condenser?

 

I haven't had the truck very long, so I'm in the fact finding stage of ownership at the moment. You're right there's no telling whats been done. I was able to verify thru decoders that the engine I have is indeed the correct size sold with the truck, but ive been unable to find the stamp to verify it is the original engine, im assuming it is. Im attempting to accurately decode the compressor stamp at the moment. Also in my Haynes manual it mentions the possibility of having two types, but didnt elaborate further. The changes begin at the expansion valve, as you can see it has 2 hoses coming out of it instead of a block connector. Then to the dryer, which also has threaded connectors, instead of block connectors. The compressor hose and dryer hose to the condenser are shown. The smaller one looks rebuilt at one point, the other looks original.

 

That haynes manual is good for one thing. Rip the pages out a few at a time toss in your grill pile your charcoal on them, soak with charcoal lighter fluid and toss a match at it
