Please check notes in each part listing to ensure the Belt Tensioner is correct for your 1988 OLDSMOBILE DELTA 88 ROYALE with a 3.8L 231 engine. GATES, DAYCO, FOUR SEASONS, & ACDELCO are competing brands, and each brand's Belt Tensioner may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Belt Tensioner fits only certain 1988 OLDSMOBILE DELTA 88 ROYALE models.

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

After choosing a Belt Tensioner, 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 Belt Drive parts, other OLDSMOBILE DELTA 88 ROYALE parts, or parts for a different vehicle.
