Detailed Description

Power Select starters are engineered to provide the amp output needed for modern vehicle starting demands. This unit uses proprietary components and manufacturing processes aimed at long service life and consistent performance. With its Ford family application, 12-tooth drive, and flange mount design, 6646R is suited to many Ford truck, SUV, and motorhome starting systems. Part number 6646R also cross-references AMS Automotive 6646 for the same application.

What It Is Used For

• Restoring engine cranking when the original starter fails
• Replacing a worn starter that clicks, grinds, or turns slowly
• Addressing intermittent no-start conditions tied to starter wear
• Correcting starting issues caused by drive or rotation mismatch
• Serving Ford truck, SUV, chassis, and motorhome starter replacement needs

Installation Notes and Tips

Verify voltage, rotation, tooth count, and mounting style before installation. Confirm the vehicle-specific fitment notes, including Ford replacement unit, without nose cone, early design, or Mexico-market applications where listed. Use the fitment data to match the exact Ford, Lincoln, Suzuki, Tiffin, or Winnebago application before ordering. Part number 6646R should be matched to the original starter configuration for proper engagement and electrical compatibility.

Quality Assurance

Power Select starters are manufactured with proprietary components and processes to support maximum life and performance. The design is intended to meet the amp output demands of today’s vehicles while maintaining consistent starting operation.
