Please check notes in each part listing to ensure the Coolant Hose is correct for your 1991 MERCEDES-BENZ 420SEL with a 4.2L 4196cc engine. ÜRO PARTS, DAYCO, & ACDELCO are competing brands, and each brand's Coolant Hose may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Coolant Hose fits only certain 1991 MERCEDES-BENZ 420SEL models.

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

After choosing a Coolant Hose, 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 420SEL 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.
