Acura TL Alternator

Have you heard a loud whine from the engine after starting your car, especially if it turned over slowly? It could be a weak alternator, and might not have the power to keep your car's systems energized. If your Acura TL's alternator can't meet stringent demands, could find yourself in trouble on the road or unable to start the engine at all. Fortunately, a DIYer can install a new one in a couple of hours, and AutoZone provides the alternator you need to get your car up and running again.

Alternators over five years old could start to perform poorly, providing less than the 13.5 volts your battery needs to recharge. When replacing your alternator, choose one that has the same amperage, connection styles, rotation, and case shape. It's easy to find the right part when you shop with your vehicle details. Not sure which one to buy? We make it simple when you shop online and in-store.

Shop AutoZone's extensive supply of parts for virtually any car you might drive, including brake pads, batteries, fuel injectors, mufflers, and your Acura TL alternator replacement. With Free Next Day Delivery, you can enjoy the convenience of shopping from home while getting your parts quickly.

    Great job


    in a year

    I initially came in because I couldn’t get a straight answer to why my battery light kept coming on while I was driving! I had just purchased a new battery and alternator recently!!! Apparently the alternator the previous guy put in was faulty after paying him a lotta money!!!! These guys at Firestone took care of me and I am very grateful and appreciative!!!
