Product Details

Denso remanufactured starters are rebuilt using a controlled test-and-replace process that focuses on electrical integrity, durability, and repeatable starting output. The Denso reman starter line is based on the company’s OE electrical component experience, and this unit follows that approach with tested internal components, replaced wear items, and final bench validation. The result is a practical replacement for drivers needing dependable starting performance in vehicles including the Chevrolet Malibu, Saturn Vue, and Pontiac Sunfire. Part number 280-5378 is also referenced in aftermarket catalogs for the same application, including ACDelco 323-1456.
