2003 Ford Ranger Alternator

Your vehicle's charging system consists of a battery, a voltage regulator, and an alternator. They all play a role in providing electricity to your pickup, but it's the alternator's job to convert mechanical energy into electricity using alternating current. Simply put, without an alternator, your car will quickly deplete the battery, leaving you stranded. You can find a 2003 Ford Ranger alternator at the right price at AutoZone.

Some vehicles will light up a battery warning light on the dash, indicating that the battery is either not charging or that there's a wider issue with the electrical system. On older vehicles, there are other dead giveaways that it's time to replace your alternator, such as extremely bright or dim lights, growling noises coming from the engine, or frequent stalling when driving. All of these could mean that you need to look for a replacement 2003 Ranger alternator.

                  About 2003 Ford Ranger Alternator

                  How to Replace a 2003 Ford Ranger Alternator

                  To replace the alternator on your Ranger, you'll need to disconnect the battery first and remove any potential electrical hazards. You can then proceed by removing the air cleaner outlet tube and the accessory drive belt. You can then loosen the alternator bolts and pull the alternator towards you, giving you space to pull the drive belt off the pulley. Lastly, disconnect all the electrical leads on the back of the alternator and finish unscrewing the bolts.
