What Needs To Convert Ac From R12 To R134a, 92 Ls200

[HatBe]

Hi,

I got 92 LS400, the AC has a slow leak, I recharged R12 last July, and it is empty now.

I call different shops and have these options:

1. Most shops recommend to convert to R134a and find leak, The conversion kit consist of a few adapters.

2. Find leak with R12 and die then fix later.

Does anyone know if it is OK (safe) to convert from R12 to R134 after vacuum out all R12, or what else need to be repleaced?

I really appreciate any feedback/suggestions.

Thanks,

HB

HBI would find the leaks first, then replace the dryer, and have the conversion done....

I agree with the shops, convert, find leaks, change the dryer, and fill with R-134.... Should work fine... I did two cars myself and they both worked...

Lenore, when you say you did yourself, did you do the work or a mechanic / dealer?

I just got my 91 LS400 converted by a mechanic. However, the compressor would not run and/or the clutch would not engage. He said the problem is with the cable from relay to clutch but evenso, the compressor and clutch likely needs replacing. The system was emptied of R134 given the a/c would not work.

Anyone have any thoughts on this?

Searching this forum, I found Tech Choice Parts on Ebay and many others there too. Anyone have any

- experience with any Ebay compressors+clutch units and

- have you installed one yourself (I would go back to the mechanic to refill / test).

Any suggestions or ideas?

Thanx in advance.
