Please check notes in each part listing to ensure the Voltage Regulator is correct for your 1990 PLYMOUTH COLT 100 with a 1.5L 90 engine. STANDARD MOTOR PRODUCTS, ULTRAPOWER, & ACDELCO are competing brands, and each brand's Voltage Regulator may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Voltage Regulator fits only certain 1990 PLYMOUTH COLT 100 models.
Clicking a "More Info" link will display a picture and/or other details about that Voltage Regulator in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Voltage Regulator, 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 Electrical parts, other PLYMOUTH COLT 100 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 1990 PLYMOUTH will not be lost if you switch.
