Stay away from the CS130. It is a solid case, small bearing, internal regulator, and problem prone. For some reason Delco named their new-from-the-ground-up alternator the CS130D. No parts are interchangeable with the old CS130. My 2008 Duramax diesel came equipped with the CS130D alternator.
The CS144 alternator is also excellent, and it can be had in very high amperages. It is larger and heavier than the CS130D. I know that there are a ton of CS144's in the pick-a-parts and ebay.
On either one, you have to make sure that the proper mounting locations are present to bolt into our old mounting system. Many new alternators have solid mounting points. I avoided the hassle and purchased my 120 amp CS130D new from http://www.qualitypowerauto.com All you have to specify is to have it set up for the V-belt pulley and clocked for a Pontiac. The business is local to me and one of the owners is president of our car club. Wheelspin also uses them for his alternator needs.
Edit: forgot that you would also need the adapter cable that they also carry. Mine is set up as a three-wire and I have a working idiot light and remote voltage sensing. |
I might be doing this upgrade to the new 62 Cat Wagon. Is this a drop in replacement for an old 3 wire? Is a CS 144 with 3 wires a drop in. The Tempest has a 1 wire and no external voltage regulator.
