Engine Size: 1.5 lt
Refrigerant Type: R12
This will be my 3rd attempt over the past several years at getting a properly functioning A/C system in my Civic. It's been a real frustrating and costly experience and I hope this to be my last time messing with it.
First time around 4 years ago I went R134a conversion with absolute horrific idle vent temps (~70 plus degrees), even with a hi-po electric fan right on the condenser. I then decided to revert to R12 but within a couple of weeks all the refrigerant had leaked out. I later on discovered the cheapo eBay compressor I put on was leaking. The performance of the R12 during this time was a bit better than the R134a but still nowhere near where I felt it should have been, particularly at idle (it would still creep up into the mid 60s which isn't enough to keep me from sweating in the summer).
Now, I'm doing the system again. Everything is brand new except the 4-5 hard lines in the system. My (new) rebuilt compressor came with all this brightly colored propaganda about being pre-filled with Ice 32 and actually specifically says NOT to drain it. Is this BS? The problem here is that I have no way of knowing how much is in there, so I have no way of knowing how much oil to add. I want to be very precise this time with proper oil/refrigerant amounts and would prefer to drain the new compressor dry and start "fresh" with proper amounts. Any reason I can't do this?
Also, the condenser is directly in front of the radiator. Currently, I have a slim electric puller fan behind the radiator on the driver side, and a slim electric pusher fan on the passenger side front of the condenser (this way they're not interfering with each other).
I've been contemplating adding a second pusher fan in front of the condenser, but this would place it in front of the said puller radiator fan. Would this be of any benefit at all or cancel each other out?
I'm really trying to get the idle vent temps down and figure two pushers on the condenser at idle would help. Thoughts?
Four Seasons Rebuilt compressor?
Bummer. Don't be surprised when your copmpressor fails again. I'll never use a FS reman. New FS are fine but never a reman.
Well what other option did/do I have? The only other TR70s I could find were ~$100 eBay "rebuilt" ones and I've already been through two of those. I tried to buy brand new from Honda but they no longer sell the complete unit. I would have had to try to piece it together from individual parts from Honda and not all of the parts are available any longer anyway.
There are new imports available if you use the right source.
What exactly does "import" mean? Does that just mean Chinese knockoff? Or is that a genuine Sanden.
And if you don't mind sharing the source I would be really interested. Like I said, I want to do this 100% proper and for the last time. I searched for about two days trying to source a new Sanden and/or better rebuilt source than Four Seasons (though I've had no problems with their rebuilt steering racks, steering pumps, etc. over the years) to no avail. It really seems like everybody sells the same stuff and it's all a crapshoot. I've been through two eBay compressors, my buddy with a '90 Civic has been through two or three from AirPro (live a few miles from them), guys on the Honda forums have all had hits and misses depending on the source. Like I said, seems like a total crapshoot, unfortunately and really frustrating for people like me.
(would also still like to remind others not to forget about my original topic/questions haha)

I would be the source. Import is a China knockoff. Frankly the China stuff is getting pretty good these days if you use the right source.
Haha so nobody has input on my actual topic?
Scroll compressors don't do much at idle, especially if they are at all worn(*). I suspect that idle performance may be compressor limited rather than condenser. Do you remember any pressure readings that you were getting? Also make absoultely sure the heater core is cutting off with the dial at full cold, Civics are really prone to that. I have a 1991 DX stock system running R-134a and performance is OK, though I don't experience really hot weather.
(*) and I doubt that any rebuilt gets new scrolls in it. Probably just a shaft seal and clutch set and clean up the outside.

Not a fan of ICE32. Nothing really wrong with it but it's not worth the cost. Sure you can drain the oil and put back the proper amount. If there is a warranty issue call the vendor and ask them if it's void removing Ice32. AS for the fan. Adding a pusher in front of a puller is not somehow I like doing. Seems to restrict air to a degree.
