Please check notes in each part listing to ensure the Coolant Level Sensor is correct for your 1997 BUICK REGAL with a 3.8L engine. STANDARD MOTOR PRODUCTS, AIRTEX / WELLS, & ACDELCO are competing brands, and each brand's Coolant Level Sensor may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Coolant Level Sensor fits only certain 1997 BUICK REGAL models.
Clicking a "More Info" link will display a picture and/or other details about that Coolant Level Sensor in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Coolant Level 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 BUICK REGAL 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 1997 BUICK will not be lost if you switch.
