Re: Parallel Flow Condenser
This Original Air upgrade kit looks interesting, too. Perhaps having F.A.A.benny refurb my evaporator box and recalibrate the POA, plus this upgrade kit, would be a good combo.

Obviously the upgraded condenser will be even better if used with an electric fan as well. |

Re: Parallel Flow Condenser
You can make your own drop-in R-12 replacement using a propane/isobutane mix, which is also available commercially if you don't want to make it yourself.
It is just as safe as R-134A, the flashpoint is higher than the 134a/oil mix that would be running thru your system. You could use the propane straight, the mix is so it will mix with the oil better. Interestingly, the van I drive at work is a 2000's Chevy van using R134a and it's performance driving around town is like my '78, yet it was built for 134a.

Why not just go to a junkyard and get one? Yea you may have to make brackets and make sure it's good but seems to me it would work. Get a 2015 are so Tahoe Suburban heavy duty truck and it should have everything you need.

As has been stated above, a great option is to just go to eBay and for about $40 someone will sell you a brand spanking new universal condenser in a size of your choosing. |

Re: Parallel Flow Condenser
>>Maybe not to you, but if you know the right vehicles to look at it will. I like going through the junkyards and finding parts that I can make work.<<
Isn't that the question the OP was originally asking? So, what's your answer? What Parallel Flow fits? Any junk yard selection or universal presents the same problems. Selecting the correct width and height is just the start. Fabricating mounts is straight forward and very easy. The fittings aren't that much of a problem, because you are attaching flexible hoses. What is on the other end of those hoses is a different problem to be dealt with separately. The real problem that is the most difficult to deal with is, which way the original fittings are pointed. How long are they? How many bends are in them? How high or low? What has to be cut or moved in order to make connections, even with flexible hoses? How big of a hole in the radiator support are you willing to cut to make it work? I used a Parallel Flow from a Chrysler 300C. I had to cut one fitting off and TIG weld a different fitting that had different bends. I did this about 13 years ago and i wasn't aware at the time if any aftermarket direct-fit parallel flow was available. My entire '67 system is from the junkyard, but I'm not about to recommend the same to anyone. '89 and '94 Cad pusher fans on the '01 Chrysler condenser. A 108* honda temp switch controls the '89 fan. The 508 Sanden came from A mid '80s VW Cabriolet. The Evap suitcase is a Automatic Climate Control unit from a '87 Lincoln Mark VII. Using original I6 4-blade fan with no shroud. The original 10DN Ex Reg Alternator is still being used. The digital control is set at 71* winter and summer. Only when the Sun is beating directly on me through the glass for long periods do I drop the temp a couple degrees. FAAbenny is correct. The condenser pictured above is the Piccolo Condenser.

Why would you cut a fitting off to just tig weld another one on. The hoses can be adapted to fit each other. I didn't cut any of them off just had new hoses made which you have to do anyway even with a kit you have to make up the hoses. Nothing is going to be a direct plug and play but with a little looking around in the yards you can find what you will need. The grille opening is big enough to make it happen. My system is a junkyard pile of parts with new mixed in. This system is 20+ years old and works great. I installed the orifice tube and 80's model condenser in the box and shot foam inside it to close up the gaps. I then used the accumulator and did away with the drier. Sight glass for 134A isn't neededed. This fall I plan on collecting all the parts for the ramp truck to install in it and do a junkyard system for it also. ![]()

Re: Parallel Flow Condenser
anyhow, im just studying up on factory systems -converting to r134, --for my 67 Camaro convertible, im reproducing the BigBlock AC evaporator cases --because a small block one is worthless--you cannot even get the ps manifold off with the small block suitcase. the only stock stuff will be the under dash heater /ac duct box--and dash controls--that are basically the same as the 67-72 trucks and the small block evaporator core in a new BBC case, all new barrier hoses, and im studying either a nippondenso or some style of GENUINE sanden, not a cheap Chinese pos, a universal parallel flow condenser, poa updated thingee and a r134 expansion valve. Four Seasons ac parts are in my home town but I don't think they sell parts direct--they used to have a store in Ft worth off university 30 yrs back--factory air. I would not pay the markup for a --p-fcondenser from old air products or vintage air or any of the other specialty outfits because its markup-- 3 times what a universal one costs..
