Please check notes in each part listing to ensure the Coolant Temperature Sensor is correct for your 1991 MERCEDES-BENZ 560SEC with a 5.6L 5547cc engine. BECK/ARNLEY, STANDARD MOTOR PRODUCTS, & AIRTEX are competing brands, and each brand's Coolant Temperature Sensor may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Coolant Temperature Sensor fits only certain 1991 MERCEDES-BENZ 560SEC models.

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

After choosing a Coolant Temperature Sensor, 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 560SEC 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 1991 MERCEDES-BENZ will not be lost if you switch.
