Had my car serviced today; an alternator replacement, in which I supplied the part. I would've given him 5 stars, but as soon as I opened the hood, he upsold me for a whole extra hour of labor. Still, it was cheaper and more convenient than having it towed and worked on in a shop.

Overall I was very impressed with Tinashe and his service. He showed up 20 minutes early and completed the job in a quick fashion. He took time to explain the issue and the process to replace my alternator.

Colin was absolutely wonderful. He showed up promptly to my appointment and got right to work. He was very kind and extremely funny. He alerted me to some of my fluids being low and explained everything I should do as a next step to keep my car running smoothly. I would definitely recommend him to anyone.

Patrick is awesome. He used to work for Nissan, so my Xterra was familiar territory for him. He took the time to inspect the car for other possible issues that might have caused problems with the charging system but was able to narrow it down to the alternator. Most shops wouldn't do that, let alone let you stand there and witness the repair. Once the alternator was replaced, the battery voltage went back to normal readings and those pesky warning lights magically vanished! Highly recommended, thanks again Patrick!

Alternator Repair Service

How does an alternator help your car run?

The alternator is the component that charges the battery in your car. When you use electrical components in your car (stereo, lights, etc.), the battery loses power. The alternator recharges the battery, replenishing the lost battery power. The alternator is located in the engine compartment. If the alternator is not working properly, your car will only stay running for as long as the battery has power stored. Once the battery loses power, your car will not start. Normally, a malfunctioning alternator will turn on the battery warning light or will have a low volt gauge reading.

Alternator

Before repairing the alternator:

The mechanic should check the entire charging system before installing a new alternator, including checking battery cables for corrosion and the condition of the battery.

Steps when replacing an alternator:

  • Inspect entire charging system (battery, cables, alternator).
  • Inspect the drive belts.
  • Test alternator output.
  • Remove and replace alternator if found to be faulty.
  • Re-test alternator output.

Our recommendation for alternator replacements:

Ask your mechanic to inspect the condition of the charging system during every major service. The mechanic should also clean and tighten the battery cables during every major service.

What common symptoms indicate you may need to replace the Alternator?

  • Dead battery or battery will not hold a charge.
  • Dim lights.
  • Battery warning light is on.

Why repairing your alternator is important:

Your alternator charges your battery, which powers the electronics in your vehicle, such as the radio and the air conditioning. The battery is also needed to turn on your vehicle. A malfunctioning alternator will not charge your car’s battery, and your vehicle will eventually run out of battery life and not be able to start.
