When to replace the starter?

Starters are relatively durable but most will eventually fail in one or more of the following ways:

• Intermittent operation of the starter. Starters can develop bad spots on the armature which will cause intermittent operation. This causes the starter to work sometimes and other times when you turn the key nothing happens.
• Starter turns too slowly. Internal electrical and mechanical faults can cause the starter to draw too much current and in some cases the current drawn will exceed what the battery can supply. A consequence is the engine may not start as rapidly.
• Unusual noises on starting. If you hear any type of grinding or other unusual noise while starting the engine, that should be investigated as the noise could reflect an internal starter failure or the noise could be due to pinion gear failure or flywheel ring gear damage.
  
• Starter doesn’t function when turning the key. In some cases, the first symptom of a starter malfunction is a complete failure of the starter motor. This happens when you turn the ignition key to start the car, the starter motor does not function at all.
