Update on where i'm at with the air con.

On my car which is a 2/77 Australian delivered 260 all of the system except for the receiver/drier is compatable for the R134a.

The fill and test ports are changed to the R134a type.

I have taken my compressor apart and am cleaning all traces of the R12 mineral oil out. (i've taken photos) It's actualy got three pistons in it, I was surprised. This then goes back together dry, with a label on it to remind me that it's dry. (getting older every day) It goes back together dry as the Ester and Pag oils used with R134a absorb moisture.

Then you take it down and get the money sucked out of your wallet for the new receiver/drier and fill and test.

I'm still looking into alternates for R134a and will let everyone know what I come up with.

Here's a really tree hug solution to your air conditioning problems. Forget those cfcs.:classic:

Tanny, is that an original 60's era swamp cooler? My dad bought one of those to use in our '59 Dodge Sierra wagon for our move from So. Ca. to Florida in June of '64. As I recall, it worked pretty good, especially since it was mounted in the rear passenger window next to where my brother and I were sitting!

As an update to my post in this thread over a year ago, I'm using R414B in both of my formely R12 cars. No problems, whatsoever. It requires no modifications to the system. Just an evac of the R12 and recharge with the R414B. It runs the temp down to 32 degrees inside the vents!

Interesting. I'd never heard of R414B so I did a quick Google search and found this:

Strangely enough, it looks like all of the varieties cost about $1/pound in quantity. I thought that R12 was extremely expensive to keep people from using it.

R12 is not available in small cans, and requires a license to buy to keep people from using it. As the supply of small cans dwindled before the licensing requirement date, the price went way way up!

I think you need to look at that again. What they show is the cost for the deposit on the 110lb cylinder. R414B costs about $250 for a 25lb. tank or about $10/lb. R12 cost anywhere from $18/lb and up when you can find it. Most R12 you will find is reaclaimed since it hasn't been manufactured since 1996. The tradename for R414B is Hotshot. I actually get it free since my friend is a HVAC tech.

The biggest problem with ACs is lack of use....the oil in the freon (whatever the type) has got to be circulated on a routine basis, or the seals get hard--and this is what causes most leaks of freon. Run your AC for 5-10 minutes once a week all year long to keep your seals from hardening up and letting your freon escape. Learned that servicing many R12 systems earlier in my career....

Any of you guys know where to get the "freon" hose for the early 240Z dealer installed A/C? I am trying to re-install my old Yorx system, and need new hose. The hoses are quite thick the larger one is 12mm ID 24mm OD. The other is 8mm ID......

I have some old a/c parts I took out of my ralley car. I'm going to be selling them if anyone is interested! you can call me at 308-325-6445

Check your Yellow Pages... Air Conditioning Supply or Automotive Hoses

In almost any town in America you will find a speciality company that will take your old fittings and make you a new hose. If you want, they will supply new fittings as well, but they may differ in appearance. If you tell them you want the look and diameter of the old hose duplicated, they will most likely be able to do that.
