Post subject:  New AC Parts on 70 dart

The dart came with Factory Air and the old 2 cyl compressor. I have the AC brackets from a Slant six Aspen that had a small rotary compressor, the sanden 4506 with a double V pulley.

My question is, will the factory stuff work with this compressor, I already have a new condenser and drier, and is there a replacement ac blower that will kick up the air flow.

Florida here and it gets a little warm.

H'mm. What's the goal with the change to a Sanden compressor?

Post subject:  Well, guess than answered my question

Thanks for the direction, guess I was thinking new was better...

Well, new is better...in condensers. The newer parallel-flow condensers are a lot better than the old serpentine types. But there's no performance-based reason to switch to a different type of compressor. Remember, if new necessarily always meant "better", you wouldn't be messing with a Dodge Dart! :shock:

The Sanden compressor is smaller and lighter and probably more efficient but it doesn't cool the car any better.

The Sanden, will contribute to a smoother idle, especilly on a slant. The compression pulses are 6 evenly spaced pulses, per compressor revolution, as compared to 2 uneven pulses on the RV-2 compressor (like a Harley V-twin or an old John Deere tractor)..

Post subject:  How about the fan ????

The infor you guys provided on the V type compressor was good. Now is there a way to get more air flow in to the car. The Dart came with a 2 speed fan that does not push enough air.

Maybe the blower motor or fan has a problem or the systems doors / actuators are not working right? I just went thru our heater/AC box and it blows quite a bit of air on all settings.
Aside from the box I would look at the switches and connections to the blower. Make sure they are clean and look for any signs of heat that would indicate too much resistance.

I am going with a Sanden on our car because the original compressor was missing and I need hoses and condenser anyway. So I am going to r-134 at the same time and this is as easy and maybe less expensive than finding a good stock compressor. There are hose ends to fit the factory evaporator outlet for # 10 hose, the standard after market low side hose size used with a Sanden. It is an easy setup to put together and get hoses etc. for if you go that route.

If you have all the stock parts and they are serviceable, I would keep them and stay with r-12. These old systems work great unless something is wrong. Old systems usually need hoses, they are not too expensive to have made. As long as it is not leaking, the cost of the the r-12 is not much of an issue. It should go for years at a time without needing work.

Compressors are just pumps, so you're exactly right. The old Chrysler compressor was actually a great piece of machinery, but the problem is that its gotten virtually impossible to get one that hasn't been rebuilt so many times that its now just complete crap. Even my very helpful local compressor rebuilding shop tells me that they just can't get good cores, and sometimes not even parts anymore. :-(

So I converted to a Sanden SD-5 on my daily driver using the Classic Auto Air kit:
http://lonestar.texas.net/~sglacker/MMC ... stall.html

I will say that even though the cooling isn't any better (and I didn't expect it to be) it is a lot smoother and quieter. Overall I'm pleased. A 7-cylinder Sanden SD7HD15 would be a little closer in capacity to a Chrysler V2 than the 5-cylinder SD5H14, but that only really comes into play at idle. And even at idle, the SD5 maintains 40-degree air on recirc, just not quite as cold as an RV2 when set to fresh air (ambient temp in the high 90s).

The displacements are:
Sanden SD5 = approx. 8.5 cubic inches per rotation
Chrysler V2 = 9.5 CI per rotataion
Sanden SD7 = 9.6 CI per rotation
Chrysler RV2 = 10.5 CI per rotation.

Slightly off-topic, does any one know a good source for compressor brackets for the Sanden? No Aspens or Volare's around here in the junkyard...

I'd go to the ClassicAutoAir.com website, and if they don't show what you have, call them up. They were really helpful. I don't know what all they have for slants in particular, but for BB and SB mopars they have bracket sets to add air to a non-air car, and a different bracket set to mount a Sanden in the stock location.

The slant six a/c bracket used by Classic Air shifts the compressor forward of the power steering.

The kit comes with a double pulley to replace the power steering pulley on the crank. The power steering belt retains its original position, but the a/c belt occupies the outermost groove of the pulley.

This arrangement does not work for my 1963 Dart. There's simply not enough room in the engine compartment to accommodate a forward postitioned compressor, unless the radiator fan is eliminated.

I also doubt the 1970 model has enough room, but I don't have a 3rd generation A body available to look. I suspect the Classic Air bracket is designed for trucks which have much more room.

Ask Classic Air before you purchase.

I don't know if all the aftermarket brackets are the same or not, but check with www.ackits.com to see where their slant-6 mount/drive kit places the compressor.

Their B/RB and LA kits for non-AC cars work just like that, but their kits for replacing the compressor on a car that already has AC are different. Calling is imperative, the website doesn't show everything they've got.

And like Dan said, try ACKits.com too, although I am uneasy about the compressors they push (Diesel Kikis, aka the Japanese arm of Bosch, sold uner the name 'Seltec' which is just the US distributor).

I have been using both Sanden and Seltec for years, in many applications, without any problems.

Actually, I would rather even use a Chinese copy/ripoff, then anybodies reman comressor. I will not even do a compressor replacement with a reman, unless a new compressor is not available. If the customer wants a reman, they can take the vehicle to a shop that doesn't care if they replace the compressor 4 or 5 times, under warrentee. Remans are total junk. Rant off.
