Oh, we'll be talking about this at DGRR, since there's no way in hell I'm going to find the time to get this job done before DGRR

Tracking on all of the above.

when feed the duster into the system. HF carries them and you can get them on ebay.
I use the HF vacuum device thats driven by my compressor to evacuate and it works
just fine and its cheap.
You want to use ester oil for the new oil too ( I think, I'll have to verify).
The link to the 152 post on the other forum is: https://www.rx7club.com/1st-gen-arch...gerant-997918/
If you want blow by blow instructions let me know and I can post em up here.
I've done this to 3 vehicles so far and all 3 have been working well for years. |
That R152A link was very informative; presuming all my reused parts (especially the condenser) can be flushed/cleaned out adequately, switching to R152A gets me the performance of R12 without having to get a new condenser.
