Please check notes in each part listing to ensure the Belt Tensioner is correct for your 2000 MERCURY COUGAR with a 2.0L 1989cc 121 engine. GATES, DAYCO, & 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 2000 MERCURY COUGAR 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 MERCURY COUGAR 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 2000 MERCURY will not be lost if you switch.
