Does anyone know the Sanden model number of the original, stock, R12 A/C Compressor (i.e. 505, 508 etc.). Thanks.

The Delorean stock compressor is an SD-510Q8494 where :
- the 5 designates 5 cylinders
- the 10 stands for 10 cu in displacement per revolution
- Q is the type of cylinder head
- 8494 defines the combination of mounting, clutch size, offset, oil amount etc.
- this compressor used to be made at Sanden's old plant in Dallas, TX but is no longer in production (mostly because it was unable to withstand the higher pressures and loads/less efficient lubrication associated with R134a)
A perfect R134a drop-in replacement would be the Sanden SD7H15QC4708:
- the 7 designates 7 cylinders
- 15 stands for 155 cc displacement per revolution (about 9.5 cu in)
- this is a quieter, more durable compressor, specifically for R134a
- this compressor is produced in Wylie, TX
- I use this compressor on my D.
See attached drawings for both.

I just did a google search for this part number: SD7H15QC4708.
Came up with nothing. I then went to rockauto.com and tried to look this number up so I could see a price. Search came up empty. Any ideas where you can buy this compressor?
Yeah, it's dirty. I drive it.

The SD lines of compressors are very end-user friendly in that it is modular, meaning that you can more or less “build” your own SD compressor using whatever clutch style, clutch diameter, clutch offset, clutch voltage, mounting type, oil amount, cylinder head, hose mounting style etc. With that you can imagine that the number of configurations is almost infinite. The combination of all of these options are defined by the last four digits, i.e. the 4708 in the case of the SD7H15. Over the years, Sanden has offered whatever combination of features the customers have required (assuming the sales volume was there) and then given it a four digit number. However, most aftermarket retailers and distributors may only have purchased certain models for specific car models and model years and/or some common config that would fit a lot of applications. Also, if you contact the retailers/distributors they are not going to know what a “4708” is. All they know is that a certain compressor will fit a 1998 Dodge Ram truck or whatever. The best chance of finding what you need is to go to a larger a/m company’s website such as Four Seasons (www.4s.com) and download their eCatalog. There are other, similar companies out there too. Google is your friend here. If you’re lucky then you may find a cross reference showing which xxxx model go on what model/make and then you may find it easier to look for that compressor in the a/m world. If none of that works, then you need to find a retailer that is willing to configure a compressor for you. I have the name of such a place at home; send me a PM and I can let you know who I contacted and what I asked for. This was 6-7 years ago so hopefully they’re still there…

Actually, finding a 4708 is very easy:
Go to www.sanden.com. Select Products and Product Search. Under Sanden Model # enter: 4708. You can buy it right there.
