I had the flat, over cooling fan mounted condenser and factory compressor on one of my '65 factory air cars.

#IMO it was quite efficient, worked well in traffic and highway speeds....but that condenser location made just about any routine engine maintenance a PITA.

You don't really want it perfectly horizontal. The outlet should be a bit below the inlet; we are collecting condensed liquid after all.

It just dawned on ol' slow-as-molasses Mr. Badwrench (me) that joelsplace was asking about a front trunk floor mounted condenser.

Quoting my idol, Emily Latella (from the original "Saturday Night Live" first season): "Ohhhhhhhh! Nevermind!"

I was. I haven't looked but I would guess that the factory horizontal one has a top inlet and bottom outlet. Does anyone know?
I'm also guessing that the tube type are less picky than the newer parallel flow type about orientation.

i have used freeze 12 with good results. It can be used in both R-12 and R-134 systems.I installed my condenser in the trunk. After three prototypes, i finally was able to engineer a set up that worked. The problem i have had is that the hot air expelled from the condenser is sucked in thru the front intake when the car is at a stand still. I am running a stock evaporator with a R-134 expansion valve. I have recorded as low as 28 dergrees with the fan on low at highway speed. I ran my hoses under the car near the right rocker panel into the right wheel well. I am running a Sanden SD-7 compressor. The condenser has two fans, one that runs anytime the compressor is engaged and the other comes on when the trinary switch senses the condensor presssure is getting too high. Attached is a couple of threads of my installation.

Ratt643,
Thank you for the infor on your build. Those links are very informative as well. Thanks.

I am still designing and making sure of my hardware choices. But need to make shrouds and ducting.

Well that's cold, but one problem - The evaporator core should never drop below freezing since the condensation will turn to ice and block the air flow. YES I've had that happen. The evap. temperature select switch can be calibrated to shut off the compressor when the evap. core drops to freezing when you have the lever at maximum cold.

Sorry for the high jack but......I'm planning on using all stock 1966 parts in the stock location with the exception of the 7 piston Sanden compressor and R134A refrigerant. Is this a mismatch of parts?
Should I consider a R134A expansion valve and a condenser designed for this refrigerant? Or just bite the bullet and have it charged with R12?

If your Sanden has any oil in it it's probably for 134. I would go with R12 but I have plenty.

At one time you could order a "R12" Sanden compressor (mineral or ester oil in it). Not sure if the option is available now. All the recent Sanden compressors come with PAG oil in them for R134a.

Confusing/conflicting claims as to using PAG oil with R12.

I imagine that the front trunk condenser/fans and sanden compressor would be the way to go for VW Type I/KG owners wishing for air conditioning?
