What is this part and why does it matter?

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Clicking noise when turning the key, but engine doesn’t crank
  • Grinding noise during starting
  • No response at all when turning the key

Installation information

Bolts to the engine/gearbox bell housing, connecting to the battery cable and ignition wiring — check the starter engages and disengages cleanly from the flywheel after installation.

Frequently asked questions

This classic symptom usually means the starter’s solenoid is engaging (causing the click) but the motor itself isn’t receiving enough power to turn, often due to a weak battery, corroded connections, or a worn starter motor.
