Please check notes in each part listing to ensure the Radiator Cap is correct for your 2003 MERCEDES-BENZ G55 AMG with a 5.5L 5439cc 335 engine. STANT & GATES are competing brands, and each brand's Radiator Cap may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Radiator Cap fits only certain 2003 MERCEDES-BENZ G55 AMG 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 on "Find More Parts", to find more Cooling System parts, other MERCEDES-BENZ G55 AMG 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 2003 MERCEDES-BENZ will not be lost if you switch.
