Installation Notes and Tips

Verify the vehicle’s original starter configuration before installation, including 12-volt electrical setup, clockwise rotation, 2-bolt mounting, and 9-tooth drive engagement. Mounting hardware and shims are not included, so reuse or source the correct service parts as needed. Confirm battery condition, cable integrity, and charging-system output during diagnosis to avoid replacing a starter for an upstream electrical fault.
