Specs At A Glance

Good To Know

Q: How can I tell if the solenoid is the problem rather than the starter? A: A solenoid that clicks without cranking, or shows no voltage at the starter terminal during a start attempt, points to the relay. Test the battery and starter first so you replace the right part.

Q: Do I need to change anything else when installing this solenoid? A: Inspect the battery cables and starter connections while you are in there, since corroded terminals often accompany a failed solenoid. Clean and tighten them before the new relay goes in.

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