Please check notes in each part listing to ensure the Oil Pan is correct for your 1979 MERCURY GRAND MARQUIS with a 5.0L 302 engine. PLATINUM PRO, ATP, SPECTRA PREMIUM / COOLING DEPOT, & DORMAN are competing brands, and each brand's Oil Pan may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Oil Pan fits only certain 1979 MERCURY GRAND MARQUIS models.
Clicking a "More Info" link will display a picture and/or other details about that Oil Pan in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Oil Pan, 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 "Find More Parts" to find more Engine parts, other MERCURY GRAND MARQUIS parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1979 MERCURY will not be lost if you switch.
