2003 Honda Civic Alternator

Alternators power interior and exterior accessories when the engine is running that include power seats and windows, heated seats, radios, headlights, and gauges. When alternators fail, car batteries drain rapidly and interior and exterior accessories start to have problems. The good news is that AutoZone has what you need to replace a 2003 Honda Civic alternator.

While alternators will last that long, it's best to replace your alternator between 125,000 miles and 150,000 miles to avoid unnecessary electrical problems. If your vehicle's electrical components are having electrical problems when the engine is running, that's also a sign that it's time to replace your alternator.

              About 2003 Honda Civic Alternator

              Replacing a 2003 Honda Civic Alternator

              You can replace a 2003 Honda Civic alternator at home if you have the right tools and parts. To ensure you have the right parts, make sure you sort by year, make, model, and engine size. Once you have what you need, start by disconnecting the battery. Then, disconnect the serpentine belt and other wires or harnesses from the alternator. Next, remove the old alternator and install the new one. The last step is to connect everything you disconnected.

              Duralast products fit pretty good

              in 7 months

              I liked that that product was to OEM specs for a 2003 Honda Accord V6 but I installed it into my 2003 Honda Civic because I needed a bigger alternator for my build but could not find one that was a bigger & oem. Autozonehas had everything I've ever needed for my custom build and at the most affordable prices with OEM quality.

              in a year

              It was fairly easy to install, there just wasn't much room to work it. But took about 2 hour or so.

              Not throughly tested

              Rebecc

              in 2 years

              My husband put this part in and it didn't even last a month (i had only driven the car a couple of times) and we kept thinking it was something else since he was advised the part had been tested 3 times. However, the customer service was excellent in dealing with the staff and getting the part changed out. (this time we got the new one since it was in stock) DT at the store off of Capitol Circle was AWESOME - he was very helpful and friendly!! I would recommend dealing with him any day
