I sure wish I had found the YOUR MECHANIC site two months ago. I know that I would have saved quite a lot of money using your services on my vehicles. Jose was EXCEPTIONAL in ALL aspects and got the job completed in the estimated time, even though the original Harmonic Balancer was quite difficult to remove from my Van. He also checked numerous things about my van to make sure all was okay and that impressed me. Thank you, Jose. I have already recommended you and YOUR MECHANIC to several friends and family.

All about Alternator Replacement

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.
