Please check notes in each part listing to ensure the Voltage Regulator is correct for your 1985 OLDSMOBILE CUTLASS CALAIS with a 4.3L 260 DIESEL engine. Special restrictions like "California only" or "with sport package" may indicate a Voltage Regulator fits only certain 1985 OLDSMOBILE CUTLASS CALAIS models.

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

After choosing a Voltage Regulator, 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 on "Find More Parts", to find more Electrical parts, other OLDSMOBILE CUTLASS CALAIS parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching.
