Please check notes in each part listing to ensure the Thermostat Housing/Water Outlet is correct for your 2003 BMW 745I with a 4.4L 4398cc [N62] engine. GATES & STANT are competing brands, and each brand's Thermostat Housing/Water Outlet may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Thermostat Housing/Water Outlet fits only certain 2003 BMW 745I models.

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

After choosing a Thermostat Housing/Water Outlet, 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 BMW 745I 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 2003 BMW will not be lost if you switch.
