Please check notes in each part listing to ensure the Alternator / Generator is correct for your 2006 CADILLAC STS with a 3.6L engine. BBB PRECISION, PURE ENERGY, DENSO, REMY, & ACDELCO are competing brands, and each brand's Alternator / Generator may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Alternator / Generator fits only certain 2006 CADILLAC STS models.

Clicking a "More Info" link will display a picture and/or other details about that Alternator / Generator in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Alternator / Generator, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Electrical parts, other CADILLAC STS parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 2006 CADILLAC will not be lost if you switch.
