Please check notes in each part listing to ensure the Idler Pulley is correct for your 1988 OLDSMOBILE CUTLASS SUPREME with a 2.8L 173 engine. GATES, DAYCO, ACDELCO, & FOUR SEASONS are competing brands, and each brand's Idler Pulley may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Idler Pulley fits only certain 1988 OLDSMOBILE CUTLASS SUPREME models.

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

After choosing a Idler Pulley, 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 CUTLASS SUPREME parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1988 OLDSMOBILE will not be lost if you switch.
