Any info on this apparently new compressor? Supposedly has Sanden-type internals in a case like an A6.

Every major supplier will have this compressor available shortly. Good chance it will work well, but with any new item we will have to see real world testing on durability.


When considering your next auto A/C purchase, please consider the site that supports you:

I have 2 of them that were recently installed as a test on customer cars. Both are relatively stock vehicles in nice, original condition with comparable V8 engines.
Both cars, 71 Chevelle and 72 Cutlass, are POA\TXV systems converted to R134a.
Both vehicles are using PAG-100 oil, were thoroughly flushed, new receiver/dryers and rebuilt hose sets.

The systems work as well as any converted, A6 equipped POA system of that vintage that I've done or seen. Vent temps in the high 30's to mid 40s depending on conditions. From a performance standpoint, there seems to be no difference between the A6 and the Pro6Ten.
The first compressor, on the Chevelle, was much quieter than I expected. The second, on the Cutlass was slightly "noisier". Nothing alarming, it just made a bit more mechanical noise in operation.
The installation was a direct bolt on with no tweaking or modification, as advertised.

The Pro6Ten is, IMHO, a very good option, however there isn't really much to be gained over the A6 (Oil slinging shaft seal excepted) It's neither an upgrade or a downgrade. I will say that it seems to draw a bit less power in operation. How much? I have no idea, but likely enough to give a slight fuel economy gain. (neither vehicle is exactly a fuel miser to begin with). It IS much lighter than the A6, if that means anything.
Both cars have some chrome or polished aluminum add ons under the hood. The Pro6Ten sure does make a nice cosmetic addition. I believe this is where the real competition with the A6 lies.

Both systems have been in service for ~3 months with no issues. So far, so good. It's early but I think they will be just fine. Time will tell.
