Please check notes in each part listing to ensure the Heater Core is correct for your 1989 MERCURY GRAND MARQUIS with a 5.8L 351 engine. VISTA-PRO, SPECTRA PREMIUM / COOLING DEPOT, PRO, TYC, & MOTORCRAFT are competing brands, and each brand's Heater Core may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Heater Core fits only certain 1989 MERCURY GRAND MARQUIS models.

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

After choosing a Heater Core, 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 Heat & Air Conditioning 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 1989 MERCURY will not be lost if you switch.
