You're right that it's tight, but I didn't have to modify anything to make it work. The triple core radiator is quite a bit thicker than the OEM unit, but with enough manhandling, it will fit. I was fortunate to have access to a friend's lift for the job. I wouldn't try it on jackstands. > As for the "high efficiency evaporator", I think you mean "condenser". Urk. Brainfart. You're correct. > I have heard rumor that PJ Grady sells a high efficiency condenser that > is supposed to improve performance with R-143a conversions. Is this > what you have? How well does it fit? They do, and that's what I've got. When I ordered it from them, I mentioned I was doing a R134a conversion, and was told that while this condenser should improve performance, it's still an R12 condenser and they still recommend not making the switch. The reason I made the switch is because my system is leaking and I'd rather find the leak on the cheap stuff that doesn't kill my progeny. It fit in there fine. It is not noticeably larger than the stock condenser, but it's got a denser build and so can expose more surface area to the air. Does it work? Well, the AC is cold, but it's obviously not a system designed for R134a. When it gets really hot, as it does for a lot of the summer in Houston, I still sweat. I'm not broiling, but I'm not quite as comfy as I'd like. We're still working on tweaking things, though. My stock compressor was going bad (the clutch, actually) and wouldn't run for more than about 15 minutes, so I replaced it. Rather than replace it with a NOS compressor from one of the vendors, I got a new Sanden SD510 from John Hervey. The secret advantage here is that all the modern Sanden units, even those labelled for R12 and with the same old part numbers, have R134-grade mechanisms, so I'm not reducing the useful life of my compressor any by running higher head pressure than it's built for. Now may AC stays cold(-ish) indefinitely. Too bad the engine won't. :-) As for your other mail about checking the fans, yeah, it sounds a lot like your situation. I know that when I check it in my driveway, the fans come on when the AC is on, but as you've pointed out, that doesn't necessarily mean anything about while the car is showing overheat. Of course, it always overheats when I'm stuck in the left lane on the highway with no ability to get out and check it, but I'll catch it eventually. Check my grounds? Check my grounds. Check my grounds. I'm getting tired of checking my grounds. I've been fighting this low voltage problem in this car since the day I got it, and I've checked my grounds a dozen times. The grounds are good. The alternator is good (140 amp Hervey unit). The positive and negative battery cables are good. I'm still baffled. I stop at a light and the volt meter drops to about 9, the blower, if it's on, slows to a crawl, the lights dim, and pretty frequently the radio even resets itself. I've checked every circuit for unreasonable draw, and found nothing. I've driven the car around with every circuit turned off except those I need, and still low voltage. I've cleaned and reseated every connection in the fuse box and every relay. I even replaced all the fuses with brand new ones. No change. Here's a fact I've been meaning to mention for a while, but never have... If I start the car cold and don't turn on draining accessories like the AC or headlights, I'll actually get good voltage at idle for a while, the first several minutes at least, but then it goes away. Cooling fans, you're probably thinking. Nope. The voltage begins to drop before the otterstat kicks them on, and it seems to be a progressive degredation as something is heating up. Now, obviously, once the cooling fans do kick on, I see another big drop, but something is happening before that point. Don't suppose this information turns on a lightbulb for anyone? -andrew Yahoo!
