Specs At A Glance

Good To Know

Q: How do I know the solenoid is the problem and not the starter? A: A failed solenoid usually gives a single loud click or no sound at all when the start button is pressed, while the starter itself stays silent. Testing for battery voltage at the starter terminal during a start attempt will confirm which component has failed.

Q: Do I need to replace any other parts at the same time? A: Inspect the battery cables and starter connections for corrosion while the solenoid is out, since loose or green terminals are a common cause of starting trouble. Replacing the solenoid alone is fine when the starter and cables test good.

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