How often should an alternator be replaced?
Interestingly enough, a vehicle’s alternator does not have a fixed maintenance schedule; rather, many technicians recommend replacing it when it fails, with a typical alternator lifespan falling between seven and 10 years (or 80,000 to 150,000 miles). Still, there are several factors that play a role in an alternator’s lifespan, from the quality of the part to the amount of electronics in the vehicle, and we’re going to take a closer look at those here.
- Driving Habits – Two elements here can shorten the alternator’s lifespan: Hard driving or constant draining of the battery by using multiple accessories.
- Vehicle Electronics – Certain electronic devices, such as powerful sound systems driven by high-current amplifiers or extra lighting, put a greater demand on an alternator, potentially reducing its lifespan.
- Maintenance and Quality – A replacement alternator’s quality, coupled with consistent vehicle maintenance, both play a role with regard to how long an alternator will last.
- Condition of Engine Bay – An overly crowded or poorly-designed engine bay can also yield premature alternator failure, mainly due to physical obstruction factors or sheer heat.
The following signs of a failing alternator can be connected to troubleshooting a potential issue:
- Dimming or Flickering Lights – Dash lights, interior lights, or headlights may dim or flicker, notably at idle or when electrical accessories are engaged.
- Battery Issues – Even if it’s relatively new, the car battery may die frequently or appear to be faulty.
- Strange Noises – A big indicator of bearing issues or a problem with the alternator is a squealing or whining sound from the engine area.
- Burning Smell – Overheating or a problem with the alternator’s wiring/belts may be accompanied by a burnt rubber odor.
- Illuminated Warning Lights – A problem with the charging system could be hinted at through a battery warning light or “check engine” indicator on the dashboard.
Additionally, a car starter may fail due to problems originating in the alternator or the vehicle’s electrical system as a whole, as they’re all interconnected. A failing alternator can prevent a charged battery from starting the vehicle by not properly charging it; as such, by maintaining the charge in batteries, alternators ensure starters have a reliable source of power any time the vehicle is driven.
A Closing Thought
Maintenance of alternators and starters is key to a properly functioning motor vehicle, and by looking for the signs mentioned above, you can keep your alternator working for as long as possible.
