Detailed Description

MPA Electrical 6489S is a remanufactured starter for GM light-duty trucks, SUVs, and vans that require a Delco-style 12-volt starter with clockwise rotation and an 11-tooth drive. The permanent magnet gear reduction layout supports efficient cranking performance in applications such as the Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Yukon, and GMC Sierra 1500. If you are replacing a worn starter on a 2001-2003 Chevrolet Silverado 1500 or a 2001-2003 GMC Yukon, this part number 6489S is built to match the listed application requirements.

This part cross-references AMS Automotive 6489 for the same application.

What It Is Used For

• Replacing a starter that clicks but does not crank
• Addressing slow or weak engine cranking
• Correcting intermittent no-start conditions tied to starter wear
• Restoring starting performance after electrical or drive-component failure
• Replacing a starter with the wrong rotation, tooth count, or mounting style

Installation Notes and Tips

Verify the vehicle’s starter design before installation, especially on 2000-2003 Chevrolet Silverado 1500 and 2500, plus 2001-2003 Chevrolet Tahoe and GMC Yukon applications that note a second design using two long bolts (12561387). Confirm the 12-volt system, clockwise rotation, and 11-tooth drive match the original unit before installation. Always compare the existing starter to the listed fitment and interchange references, including 6489S, to confirm application accuracy.
