Please check notes in each part listing to ensure the Coolant Temperature Sensor is correct for your 1988 ISUZU IMPULSE with a 2.3L 2254cc engine. ACDELCO, BECK/ARNLEY, & FOUR SEASONS are competing brands, and each brand's Coolant Temperature Sensor may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Coolant Temperature Sensor fits only certain 1988 ISUZU IMPULSE models.

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

After choosing a Coolant Temperature 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 on "Find More Parts", to find more Cooling System parts, other ISUZU IMPULSE 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 1988 ISUZU will not be lost if you switch.
