SC300 AC Lines, HIGH LOW?
I am currently still on R12 and I will be doing the R134 retrofit kit soon but need to locate the HIGH side. If I had to guess it would be the line(Schrader Valve) up front since it is easier to get too but I wanted to be certain before I fit the new valves on. For those who are familiar with this can you tell me where the HIGH side is?

^^If you mean what is involved in retrofitting R12 to R134, here is the answer: It entails swapping new caps for the schrader valves high and low, draining the R12, and recharging the A/C with R134. I'm probably forgetting stuff since it's been so long since I did it. If you mean, what does the retrofitting kit contain: It contains the new valve caps, 3 cans of R134 refrigerant, the charging hose and gauge, and a couple other small details.

^^I'm pretty sure they are universal. I didn't use a specific model retrofit kit. BTW, you have to have the A/C professionally evacuated. All of the R12 needs to be gone. I didn't do that though, because in the trunk of my SC was, suprise suprise, an R12 A/C compressor, so there was absolutely zero traces of R12 freon inside it. Charged it last fall, still working perfectly right now.
You can find the kit at Wal-Mart actually, though, places like Auto Zone, Pep Boys, O-Reillys and ect should obtain a retrofitting R12 to R134 kit. Because everyone want's to protect the environment...right?

I bought mine from Oriellys for about $6. Similiar to the kit below but just the replacemet valves, my bro in law vacuumed the system out and refilled it with R134. Oreilly sells 2 kits, one is
universal for most vehicles while the other one is specifically for earleir GMs models.
