Please check notes in each part listing to ensure the Thermostat Housing / Water Outlet is correct for your 1975 GMC P35 with a 4.8L 292 engine. Special restrictions like "California only" or "with sport package" may indicate a Thermostat Housing / Water Outlet fits only certain 1975 GMC P35 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 "Find More Parts" to find more Cooling System parts, other GMC P35 parts or parts for a different vehicle.
