Specs At A Glance

Good To Know

Q: How do I know if my starter solenoid has failed? A: Common signs include a single loud click with no crank, intermittent starting, or no response at all when the key is turned. Testing voltage at the solenoid terminals confirms whether the unit is passing current.

Q: Is this solenoid hard to install? A: Installation involves disconnecting the battery, removing the old solenoid, and transferring the wiring to the new unit. Basic hand tools are enough, and the job typically takes under an hour.

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