  • Older A/C pre 93

    Hi all
    Im having probs getting anyone to regas my system,they only seem to do the new type R132,whereas cars pre 10/92 generally have R32 which is now illegal.
    There are some gases which can be used in this older system i.e. RS24 or R132a(same as R132 with additives).
    Anyone out there no any more on this problem or anyone who can regas in the N london Essex or Herts area?

    A friend of mine has just had this problem with a 1992 Honda Prelude. The place he took it to said that they would have to rebuild the compressor with new type seals and then they could use the R132 or whatever it is.

    I think they quoted about £60 to do the lot, could be wrong though :confused: I'll check if you like.

      I recently had my 93 S2 in to have the aircon looked at. I was warned before they started that if it was the older gas (non-ozone friendly) that I would be looking at a huge bill for conversion.
      Whether they told me this because they didn't want the hassle, I'm not sure, but it turned out that I've got the newer gas anyway.

        That would be great if tou could get that info for me Leigh,but it sounds much cheaper than i have been led to believe.

                Mine is a 3b also i have heard about this R132a,not found any outlets who use it as of yet though.Its the same as the newer stuff but with additives to make it flow through the older A/C systems we have or it wouldnt circulate so ive been told.

                  Not blowing my own trumpet here but old R12 systems such as older s2's, like mine, can be easily regased. It is a substitute gas called R143a NOT R134a!!!!
                  It is fine with old seals etc, will not effect performance of a/c system and is cheaper than a conversion kit.

                  IMHO these are a walking disaster, dont have one done you will suffer seal and pipe failures. Any good a/c company can perform R143a top ups, i run mine on proper R12!!! Source is secret!!

                  But i also have used the alternative in the past with no probs, many of my customers also use this gas with no probs

                      3B regas

                      Guys I have the same problem with my 92 3B which is in desperate need of a regas and I assume that I have the early gas.

                      i spoke with Whites Audi near me and they said about £1200 - £2000 to replace all seals and regas with the later stuff as they do not and cannot regars with the original gas.

                      However I found a place in Kent last year who said he would replace all seals and then regas with the latest stuff for about £200.....! I did say had he seen an Audi Coupe S2 aircon plumbing before and he said yes no worries and that he thought the price would be still around £200.

                      I never managed to get there (0ther problems and costs) but I will dig up the details if anyone is interested!

                      Cheers,

                        By chance, tomorrow I am going to Essex to have a new drier fitted and system regassed with suitable gas. Tis is being done by company (one man band) who have worked on my S2 3B coupe before, and very good work.
                        I will let you know details of gas, work done, costs and effectiveness of system after my visit. I will not have this info until late Mondfay, possible Tuesday, as will not be back at computer until then!

                          First off -

                          The old refridgerant is called 'R12' (R-twelve)

                          The new stuff is called 'R-134a' (R-one-three-four-A)

                          Secondly -

                          I have heard of specialists who can use some sort of funky legal refridgerant to service the older (now illegal for new cars) systems. The real trick in any such conversion is that the lubricating oil MUST be compatible with old system seals. There is some sort of mineral oil availble to A/C specialists for this purpose. Quite how they calculate quantities etc is a mystery to me...

                          This approach is MUCH cheaper than a full R-134a retrofit which requires ALL the seals and several other components to be changed as the oil used in R134a systems is utterly incompatible with that in older R12 systems.

                            Hi Ian

                            Let me know how you get on and prices etc,i have found a guy near bluewater KENT who reckons he has a suitable FUNKY gas as Paul put it,and a guy in Cheshunt who says"he is getting a suitable regasser for older systems in September?
                            Problems i see with all this is that there are various different soloutions to this query
                            1: Have your system updated with new seals etc apparantly V pricey but the only really safe soloution?

                            2: Have a FUNKY gas put in taking a chance the vendor knows what he/she is doing,if not i guess it could either not work properly or totally **** your seals? and this seems to be offered by one man bands? elusive? any comeback?

                            3:Just let yourself cook!!!

                            Think i will go with 2 as it stands if it works ACE if not it will need a rebuild anyhow.

                            P.S. David if you can find that info that would be much appreciated too thanks.

                              This gas is completly compatible with old seals etc. NO need to change anything. Its is R143a yes 143a NOT 134a. I have knowledge on this subject and it is safe to use and will NOT cause any probs. Trust me i use the stuff in my own car. ANY good company worth its due wll know about it and will do this for you.
