The alternator is essential to keeping the vehicle battery charged and the car powered. The procedure for removing and replacing an alternator on a 2002 Hyundai Santa Fe can vary depending on the engine type. In any case, you need an exact duplicate of the old alternator to install in its place, with the exact same size and location of the terminals and the same identification numbers imprinted on it. It's best to remove the old alternator first and then get the new one.

Disconnect the vehicle's negative battery cable, loosening its cable clamp nut with a wrench.

Unplug the electrical connectors for the alternator.

Step 3

Loosen the upper adjusting mount bolt and the lower mount bolt with your wrench, then turn the adjusting bolt counterclockwise to loosen the drive belt. Remove the drive belt.

Step 4

Remove the alternator's two mounting bolts and remove the alternator.

Step 5

Install the replacement alternator and attach the mounting bolts.

Step 6

Reinstall the alternator drive belt and then tighten the upper and lower adjusting mount bolts.

V6 Engine

Step 1

Disconnect the battery cable as described above.
