Alternator Repair Service

How much does a alternator repair cost?

The Alternator price depends entirely on the vehicle but for most domestic vehicles the cost for an alternator is around $250 to $500 and requires between 1 to 2 hours to replace. The cost for imports ranges from $400 to $1000 and the labour times can be between 1 to 3 hours. You can replace the alternator with a brand new OEM one, or a restored one. The restored one is usually a little bit cheaper – either way the choice is yours.

What's an alternator?

The alternator is the part 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 found in the engine compartment. Your car will only stay running for as long as the battery has power stored if the alternator is not working properly. Once the battery loses power, your car will not start. Normally, a faulty alternator will turn on the battery warning light or will have a low volt gauge reading.

How do you know if need to replace your car's alternator?

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

How to replace an alternator

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

Our recommendation for alternator repair services

During every major service, ask your mechanic to inspect the condition of the charging system and should also clean and tighten the battery cables.

Why repairing your alternator is important

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

My wife’s car would start but stall at traffic lights. My best guess after checking battery and belts was that I’d require a new alternator. For the cost of a tow, the instamek mechanic diagnosed problem and got the car running. The technician Jack found a faulty sensor, cleaned the contacts and my wife is now happy once more. Very courteous and thorough service. No doubt I’ll be using them in the future.read more

Second time with InstaMek. After my alternator belt snapped, I contacted InstaMek, and with in an hour Alex was at my place with all the necessary parts. In the next hour my car was fixed and ready to go. I was impressed with communication, quick and convenient service. Good people, great service, very highly recommended.Alex was on time and inspected the car. Gave me great advice on possible fixes. The communication with the company is outstanding. It's both emails and text, and in this digital world it is very welcoming. I knew exactly when the mechanic would arrive and if there were any issues when arriving late. Absolutely outstanding and convenient service. I'm will definitely call on them again.read more

So glad I called InstaMek instead of trying to take my three little kids with me to the nearest dealership. Turns out my battery was dead and alternator needed replacing, which they couldn't repair in my carport. They referred me to their awesome partner repair shop, which built on InstaMek's diagnostic and completed the job the next day.

Had a great experience. The team was well organized, responsive, and extremely helpful. The mechanic arrived on time and was very professional and knowledgeable. My timing belt and alternator was replaced and I'm very happy with the quality of work done. The experience was truly hassle free as promised.

First time I have used InstaMek, and I must say these guys are awesome. Needed an alternator replaced. Quote was fair, lower than my regular mechanic actually. Quick to respond. Arrived early so that's always nice. The mechanic, Hany, was professional and friendly. When booking for the appointment, I accidentally gave them the wrong vehicle model, was not a problem for Hany, he's very knowledgeable and knows his stuff. Excellent service, reliable, honest, fast, no issues after replacement. I am actually glad I had car troubles and had to call these guys to come to me, or I wouldn't have experienced such great service. Would call these guys again if I am ever in trouble. Thanks guys!read more

On a weekend trip to Edmonton, my car started to smoke soon after starting up. Not knowing any mechanics in town, it was fortunate that InstaMek was open on the long weekend. Hany was knowledgeable and quickly replaced the alternator. He and Kyle were very helpful and were able to get the car ready for a safe long drive back home. Thanks InstaMek!
