Hey guys!

It'* been a while since my last post about my Eighty-Eight, but another issue arose which needs to be addressed. I had a small leak in my Freon valve and I just fixed it, but consequently I lost all my Freon. For the 3.8L, what are the specs for to recharge the system?

Thanks in advance!

Sometimes a sticker is stuck somewhere in the engine bay near the A/C system telling you how much to put in. My 97 Bonneville says to put in 2.0 lbs of refrigerant.

Yeah, but mine lost it a long time ago. Should I check behind the A/C canister near the firewall?

If you already lost it, thats the only one then. Best way to find out would be either Alldatadiy.com or the dealer.

A concern, is this still an R-12 system? I ask because my '93 is one.

If so, really the best practice is to ensure it has the proper amount/type of oil, and then best guess it, assuming it has already been converted. Just fill until the pressures come in to spec, and the temp in the cabin drops. If the fails were so bad that, it might be best to evac the system, and then charge properly.

Yeah, it is an R-12, and I'm basically going to convert it to R-134. I found out how much I need to add; the top of the A/C canister had a label of 10kg of Freon.

I found the label on my canister, so I'm gonna start the conversion and EVAC the entire system all together.

If you are doing the conversion on this go around, then you will evac, and you will need to do the conversion kit (fittings, and it also has a very specific oil charge).

Even the shops at this point charge it until pressures come in to spec, and it cools good. The conversion throws off what the charge should be, so guess work is usually the best way.
