Please check notes in each part listing to ensure the Belt Tensioner is correct for your 2004 CHEVROLET EXPRESS 2500 with a 5.3L 323 FLEX engine. DAYCO & FOUR SEASONS 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 2004 CHEVROLET EXPRESS 2500 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 CHEVROLET EXPRESS 2500 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 2004 CHEVROLET will not be lost if you switch.
