Specs At A Glance

Good To Know

Q: How do I know if my solenoid has failed? A: A single click or no sound at all when pressing start, along with good battery voltage, often points to a failed solenoid. Testing for voltage at the starter terminal during cranking confirms the diagnosis.

Q: Do I need to replace the starter at the same time? A: Not necessarily, but inspect the starter and all cable connections while the solenoid is out. Corroded cables can mimic solenoid failure and are worth addressing during the same repair.

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