A/C hoses layout or diagram

[Rick 930]

I own a 1986 930S and just installed a RennAire System II with Desert Duty front condenser - Sanden 507 compressor-Pro Cooler.

My car has a Koklen intercooler, next to it there's the rear condenser (12X12.5X2.25in).

I'm almost done with RennAire System II, but would like to know how is the hoses connection/diagrams or layout of the RennAire System II with Procooler and rear condenser. I'm not really sure how to connect the rear condenser with remaining system.

Any drawings, pictures are welcome.
I did call Renn Aire but they don't have a diagrams or layout for what I want to do.

BTW: I did serach but didn't found the info.

Thanks.

I did the same install on my 86 - although not turbo. I don't have a drawing but I can tell you that the hose exiting the evaporator that used to run down the passenger side to the compressor now returns to the procooler in the DS fender well. From there you run the suction line down the drivers side and across the rear of the tub back to the passenger side and then follow the original routing to the compressor. From there the lines run the same as the original system you removed. Hope this helps.

Rick,

I'm not sure if this is what you want. Some member took this pix several years ago, then "Rusnak" added the text so I could figure out what went where. Once he did that for me it was slam dunk, I thought Rennaire's directions and schematic left a lot to the imagination. Dumb me...

Sorry for side tracking, but I've been putting some thought into doing something with my crappy AC while I'm living in super hot summer land. Seems like the Denso is what came with the car...but getting a new one costs more than the new improved Sanden. I'm always thinking cost goes along with quality...but would the Sanden be better?

And for those who have installed the system. Does it actually make a huge difference? We're talking 110 degrees in Las Vegas at times...will it be cold?

Do you reuse the old rear condensor, or does the kit replace it with something better?

Kaliv,

I don't if you have a good working compressor that you're going to gain a lot by changing it out. Your money is going to be better spent on a new evaporator, evaporator blower motor, good hoses if you need them. And I would suggest because of the area and temps where you live you'll need an additional condenser to bring the cabin temps into a comfortable range.

I would talk to Griff of Griffiths... He's very knowledgeable, his products are good, and remember that our host carries his equipment.

+1 on not getting much improvement by replacing the condenser. Unless its leaking or otherwise not working I'd leave it alone. You can tell if its leaking by looking for a dark oil streak on the decklid above it. If it is leaking then the Sanden 507 is a good replacement.

When I replaced my system with the Rennaire kit the only component I kept was the rear decklid condenser, mainly because I couldn't find an upgraded drop-in replacement. Still, I'm very happy the performance. When it's 110 in Tucson I get mid to upper 50s vent temps with R314a.

I installed the RennAir High Flow Evaporator on our '86 along with the RennAir earlier Pro Cooler dryer.

I also adjusted the A/C temp switch for a 10 degree compressor on/off window precluding evaporator freeze-up.

On a 75 degree day, the compressor activates @ 50 degrees and shuts down @ 40 degrees center duct temperature.

In Palm Springs on a 95+ degree day we get center duct air temperature at 45-50 degrees.

All other components are factory original.

Good luck,

Gerry
