Please check notes in each part listing to ensure the Thermostat is correct for your 2001 MERCEDES-BENZ SLK320 with a 3.2L 3199cc engine. BECK/ARNLEY & QUINTON HAZELL are competing brands, and each brand's Thermostat may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Thermostat fits only certain 2001 MERCEDES-BENZ SLK320 models.

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

After choosing a Thermostat, 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 SLK320 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 2001 MERCEDES-BENZ will not be lost if you switch.
