Specs At A Glance

Good To Know

Q: How do I know if my starter solenoid is failing? A: A single loud click with no crank, intermittent starting, or a solenoid that stays engaged are the usual signs. Testing voltage at the starter terminal while cranking confirms whether the solenoid is passing current.

Q: Do I need to replace the starter motor at the same time? A: Not always. If the starter spins freely when jumped directly, the solenoid is the likely fault. Inspect battery cables and grounds first, since loose or corroded connections mimic solenoid failure.

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