This page keeps the click/no-crank symptom, battery follow-up, and access steps near the top so owners can decide quickly if the starter is the real problem.
Direct answer

- • Starter part: Starter motor
- • Use the click/no-crank symptom before replacing the starter.
- • Check battery condition, wiring connections, and the mounting area first.
- • Plan for under-vehicle access on many layouts and clean the mounting surface for a strong ground.

- • Confirm mounting ear count and electrical terminal layout.

Next step
Keep the battery and charging pages nearby
A weak battery or charging system can mimic a starter problem, so the follow-up pages matter here.
