During the winter months, the condition of the starting and charging systems in your Chevy becomes even more important, due to the extra power demands that the cold presents, and poorly working Chevy alternator could render your vehicle unable to start in the morning. Though the unit may, in rare circumstances, fail entirely in less than a second, it more typically fails over a period of days, weeks or even months, with the power available slowly declining. Within the unit are three distinct circuits, which produce three separate electrical currents in one complete rotation. If one of these circuits fails, the total amount of current produced by the Chevy alternator will be reduced by a third. This will reduce the total amount of power left to recharge the battery, after all of the accessories and lights within the vehicle get their needed amount of electricity. In addition, more demand will be placed on the other two circuits, accelerating the eventual demise of the entire Chevy alternator.

Required skill level: Intermediate
Tools and materials needed
- Socket wrench
Disconnecting the battery
Disconnect the negative battery line of the vehicle. Make sure that the battery cable stays entirely separate from the battery all throughout the replacement procedure to avoid any mishap and injury. Then, locate the tensioner pulley. You may have to shift it to slide the belt off the pulley. To easily slip off the serpentine belt from the pulley and all other related parts, use a correct size socket wrench, then; rotate the belt-tensioner counter-clockwise. When the tensioner has loosened enough, pull the belt from the pulley.
Taking out the old alternator
With the battery out of the way, get to the wiring harness that is connected to the back of the Chevrolet alternator. By pressing on the tab, detach the clamp part of the main connector. Pull the main wire away from the alternator. Take out the nut from the secondary connector. Also, pull the secondary wire away from the alternator. Label the wire and bolts, if needed, to avoid confusion and for easy reattachment later on. Then, use the correct size socket wrenches to remove the 3 mounting bolts from the alternator. Carefully raise the old alternator from the engine bay and set it aside.
Placing in the new alternator
You are almost done. To finish the replacement process, just do the removal stages in reverse. Place the new Chevrolet alternator into the support clamp. Securely tighten all the mounting bolts. Bolt in the nut on the secondary connector to reattach the secondary cable to the alternator. By pressing on the tab again from the main cable, reattach the main wire. Make sure to push the wire in until the tab secures. Again, rotate the belt tensioner counter-clockwise once. Put back in the serpentine belt and reconnect the negative battery line. Give special attention to the belt routing and tensioning.
Start the vehicle.
