Discussion in 'Accord' started by Colin Richardson, Aug 20, 2003.

  1. Does anyone have experience converting their R12 system to R134a ?
    I saw that interdynamics ( has a kit. Does this kit work..
    anything to look out for etc.

    All help is appreciated on this matter.

    does the kit contain? Most important is purging the system ABSOLUTELY
    moisture free before recharging with R134a. Even pro shops quite often
    mess up.

  3. Additional information on interdynamics conversion kit.

    Kit contains:
    + 8 1/2 oz. R-134a Ester Oil Charge with O-Ring Conditioner
    + R-134a charging hose & can tap valve
    + Low and high service port adapters with color coded protective caps
    + SAE spec retrofit label

    Process is outlined at
    1. Removal of Remaining R-12 in an EPA Approved Manner
    2. Attachment of R-134a Service Port Adapters
    3. R-134a Oil Charge
    4. R-134a Refrigerant Charge
    5. Attachment of Retrofit Label

    They do say in their FAQ (
    What about the old oil left in the system? Don't you have to drain that?
    No. The mineral oil left behind will not mix with the R-134a
    That is why we add Ester Oil, because it will mix with R- 134a and
    lubricate the system components.
    The mineral oil just finds a low place in the system, where it stays,
    until it is removed at some later date during future
    maintenance or repair. The mineral oil does no good, but it does no
    harm. It's just there.

    I did my son's '90 DX two years ago. Just followed the directions.
    Still works fine. He has 225000 miles on it, in N.E.Ohio. bob

    I remember when these conversion kits were first put on the market they were
    talking about flushing the system, and that may of been to remove the oil
    from the old system. This may of been a extra step to ensure that the repair
    shop could afford steak and beer on the customer, for there next company
