            Installing Your New Chevrolet Alternator in 3 Easy Steps

            If you have some space, some background, and experience in the automotive area, chances are, you can replace your Chevrolet alternator by yourself. You can save a lot of bucks and avoid taking a trip to your local mechanic. This task can be completed in 1 to 2 hours. Just follow these easy-to-understand steps on how to replace your vehicle's alternator.

            Required skill level: Intermediate

            Tools and materials needed

            • Socket wrench
            • Screwdriver
            • Rag
            • Gloves

            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.

            Tips and warnings

            • Before starting the replacement, it is vital to first disconnect the battery. Failing to disconnect may end up causing damages as well as injuries.
            • A defective battery or starter can show similar symptoms as a broken alternator. Check first before replacing the alternator.
            • Avoid alternator with a high charge as this can cause issues on your vehicle's sensors as well as damage the battery.
            • Never disconnect battery cables while the vehicle is running, even when just making sure, if you have a defective alternator.
            • If you bought your alternator replacement from a junkyard, make sure to inspect it first before starting reassembly. Make sure it is fit to function for your application.

            Bosch Alternator

The Bosch alternator is also able to meet original equipment standards for maximum output. Increased brush life and reduced electrical interference are also some of its other benefits. There is also considerably less vibration and noise, allowing for a smooth and quiet operation. The fit of the Bosch alternator is no problem, too. And with a two-year limited warranty, there is no need to fret in case something goes wrong with it.

            AC Delco Alternator

            If there is a replacement alternator that could live up to original equipment specifications, then that would be AC Delco alternator. Manufactured to perform as if it's a part fresh from the factory that came with the vehicle, it is built with either OEM components or quality aftermarket parts. AC Delco alternators are only remanufactured with 100 percent new brushes, bearings, and bushings that are tried and tested to help in performing the overall function of alternators--to supply power to the electrical systems of the car. They also make sure that the battery is charged while the engine is running. AC Delco has also employed Failure Mode and Effect Analysis (FMEA), which is vital in the continuous process of developing and improving the product. It is to ensure that these alternators will not only stand the test of time but that it could really deliver better and better performance. All AC Delco alternators come with a one-year or 12,000-mile warranty.

            Replacement Alternator

            When the alternator starts to wear, there is no better way to replace it than with a Replacement alternator. Built from high-grade raw materials, it is proven to last long and hold out even under extreme heat or intense electrical demands. Replacement alternators are also on a par with original equipment with a product fit like that of factory parts. They are custom-built to match the specifications of the vehicle, so there is no reason for needless worrying. Replacement alternators boast of a 145-amperage output as well, making sure that they carry out power to the vehicle's electrical systems with efficiency. Replacement alternators also ensure that the battery's charge is maintained while the engine is running. They also come in with a very handy installation manual for first-time DIYers. When these alternators are purchased, they don't usually have any adapter harness with them. But with a two-year, unlimited-mileage warranty, it should be enough and worth the price.
