Please check notes in each part listing to ensure the Temperature Sender / Sensor is correct for your 1988 PASSPORT OPTIMA with a 1.6L engine. Special restrictions like "California only" or "with sport package" may indicate a Temperature Sender / Sensor fits only certain 1988 PASSPORT OPTIMA models.
Clicking a "More Info" link will display a picture and/or other details about that Temperature Sender / Sensor in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Temperature Sender / Sensor, 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 PASSPORT OPTIMA 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 1988 PASSPORT will not be lost if you switch.
