Specs At A Glance

Good To Know

Q: How do I know the solenoid is the failed part? A: A solenoid that clicks without cranking, or shows no continuity across the main terminals when energized, is typically the fault. Confirm battery voltage and starter condition first, since those can produce the same no-start symptom.

Q: Do I need to change anything else when fitting this part? A: Inspect the battery cables and starter lead for corrosion and replace any damaged terminals before installation. Tighten the mounting bolts and terminal nuts to the factory torque to keep the connection stable under vibration.

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