Please check notes in each part listing to ensure the Idler Pulley is correct for your 1990 MAZDA B2600 with a 2.6L engine. Special restrictions like "California only" or "with sport package" may indicate a Idler Pulley fits only certain 1990 MAZDA B2600 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 "Find More Parts" to find more Belt Drive parts, other MAZDA B2600 parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1990 MAZDA will not be lost if you switch.
