This guide provides instructions on how to replace the alternator on a Hyundai vehicle.
The photos and video clips in this guide are from a 2016 Hyundai Elantra. These instructions should still help you change the alternator on most Hyundai vehicles equipped with the 4 cylinder engine, including Hyundai Sonata, Accent, Santa Fe, Veloster, Tucson, Kona, etc.
Park your Hyundai, set the parking brakes, turn off the ignition and open the hood.
Locate the battery in the engine bay. Disconnect the negative battery terminal before you start work on the alternator.
Locate the alternator on the engine.
Disconnect the alternator electrical cables by pressing on the electrical connector then pulling it.
Next, remove the 12 mm bolt that secures the alternator main harness.
Next, you need to remove the serpentine belt. Loosen the two alternator bolts. There is a 12 mm and a 14 mm bolt that needs to be removed. Loosen the bolt that tightens the serpentine belt. Now, you can push the alternator down and remove the serpentine belt.
Remove the alternator. The electrical connector should be disconnected at this point.
Install the new alternator in reserve order.
Tighten the alternator bolts to twenty lb-ft. Remember that you need to adjust the alternator so that the serpentine belt is tight before you torque the bolts. The alternator is the mechanism used to tighten the serpentine belt. If you start the car and hear squeaks, that means that you didn't tighten the serpentine belt properly, and you need to retighten the belt.
