Please check notes in each part listing to ensure the Radiator Cap is correct for your 1987 BMW 518I with a 1.8L engine. Special restrictions like "California only" or "with sport package" may indicate a Radiator Cap fits only certain 1987 BMW 518I models.
Clicking a "More Info" link will display a picture and/or other details about that Radiator Cap in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Radiator Cap, 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 Cooling System parts, other BMW 518I 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 1987 BMW will not be lost if you switch.
