Alternators

Keeping your Subaru's alternator in good condition is extremely important for the operation of your vehicle as a whole. There are many different electrical components in your car that rely on the operation of your alternator. Your battery doesn't have enough power on it's own to supply to these systems, and your battery actually relies on your alternator to keep it functioning as well. The alternator works to recycle your battery power and recharge it throughout the day. This is why having a quality alternator under the hood of your Subaru is so important. When it comes to how your alternator is performing, there are several things you can look for that might indicate you need to get a replacement. They are parts that tend to fail gradually, so there are usually signs of wear and tear that occur. Difficulty starting your vehicle can be a major symptom. Headlights and dashboard lights also might start to dim and flicker as a result of an alternator that isn't operating properly. Since many of the symptoms of a failing alternator are the same as a failing battery, it's important to get both components checked to ensure you know where the problem lies. Get a replacement alternator here when you need it at Subaru Part Source.
