A condenser will run you around $80-100 and another $50-120 for a fan, depending on where you source your parts. You'll also have the hoses and fittings which, again, depending on where you buy, and how many new hoses you install, can run anywhere from $50 up. If you do this, just remember that the receiver/drier must be located between the *last* condenser and either of your evaporators, so if you have one mounted in a front wheel well, you'll have to move it rearward. > Can someone measure and give me the dimensions of the Vanagon AC condenser > for late model 90-91 factory AC. > > They're all basically the same. The late model condensers are solid, whereas the earlier models had no fins/tubes behind the crossbar that's between the grills. Both about 17" high by 21" wide. > I'm looking into whether or not I can find a super efficient condenser in > the specialty aftermarket air suppliers....that will fit in place....and > increase cooling capacity for for my dual AC setup (Westy overhead in the > rear....Behr in dashboard). > Any new parallel flow condenser will be much more efficient than the fin and tube OE units. But the closest in size I could find was a 14" x 21", or 17" x 15" (basically a wash). I installed the 17" x 15" in my '86, along with an R-134a retrofit, and it works better than with R-12 and the old condenser. I had the split condenser, however, so it had the same surface area as the replacement unit. Take a look at http://www.ackits.com/c/Parallel/Parallel+Flow+Condensers+-+Aluminum.html Although I haven't found a source for them, if you can find parallel flow units in, say 12" x 21", you could probably stuff two of them up front. You should have just enough room to stack them vertically, and you'd have to fabricate a "U" connection to tie them in in series. Bear in mind, however, that the more efficient you make the front condenser, the hotter the air will be hitting the radiator. If you do a stacking arrangement like this, you will not only be restricting the airflow to the radiator more than it is now, you'll be supplying it with warmer air as well. So, if you have any engine heating issues, I'd shy away from this approach. > When last working, I was getting 60 degrees at the front vents....still > very welcome when outside temps are in the 90's...but I'd like to explore > ways to get those vent temps down. > > Maybe have to install two condensers...but rather not...since this is a > Syncro...and gets bashed about underneath some. > Also keep in mind, any replacement condenser you get will have different fittings, and they will not be on the bottom, like the late model OE condensers. At a minimum, you'll have to modify both hoses/fittings at the condenser. If you're running R-12, you *can* use splice fittings, although they will leak some, but if you've switched to R-134a you'll have much bigger problems with leakage.
