How do you replace the alternator on 2002 Kia Sedona?

Answer 1

There is a metal pulley between the alternator and the crankshaft. Loosen the nut in the center of the pulley and adjust the tension with the bolt just under the pulley. This is best done from under the automobile.

But.... even though you you do all that, the alternator bolts have to be taken out which you cant cause of the frame of the mini-van you have to loosen the motor mounts and lift up the engine till the alternators bolts are clear from the frame and A/C lines

warning* oil pan is very delicate and you will have to push up the engine to its extremes

That is the wrong way.

The correct way (and this is straight from a Kia dealer tech)

First, set aside between 2 to 3 hours depending on your mechanical ability and tool selection.

1. Unhook the battery terminals.

2. Loosen the idler pulley, remove the belt.

3. Remove the top radiator support metal structure that the hood latch, the horn, etc are attached to.

4. Remove the cooling fan.

5. Loosen the radiator and condenser if a/c equipped.

6. Remove the O2 sensor.

7. You can finally get to the alternator and see that you'll have to slide it out from the front of the engine.

8. Now the bottom bolt is a little too long to remove but it will still allow you to remove the alternator with it out as far as it will go.

9. The alternator also has compressed retainers where the bolts go in to help it to stay in place. Using a small cold chisel or screw driver you can easily push them back in.

10. Remove the alternator, use a piece of cardboard so you don't brush against the radiator.

11. Reinstall new one as removed.

12. Follow mfgrs directions on alternator hookup so as not to void warranty. (you do NOT want to do this again if it fails).

I have personal installed 5 alternator using this method on my own 2002 Sedona. So spend the money and get a good one so you don't have to do it more than once.
