Please check notes in each part listing to ensure the Water Pump is correct for your 2003 MERCEDES-BENZ CLK500 with a 5.0L 4973cc engine. HYTEC, A-1 CARDONE, GATES, ACDELCO, & BOSCH are competing brands, and each brand's Water Pump may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Water Pump fits only certain 2003 MERCEDES-BENZ CLK500 models.

Clicking a "More Info" link will display a picture and/or other details about that Water Pump in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Water Pump, 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 CLK500 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.
