Specs At A Glance

Good To Know

Q: How do I know the solenoid is the problem and not the starter? A: A single loud click with no crank often points to the solenoid contacts, while a slow or grinding crank usually indicates the starter motor itself. Testing voltage at the starter terminal during a start attempt helps confirm which part has failed.

Q: Does this solenoid need any programming or special tools? A: No programming is required since it is a mechanical and electrical relay, not a computer module. Basic hand tools and a quick battery disconnect are enough for the swap.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
