4.6 alternator tutorial ???

[dmulc]

Can anyone provide a "how to" for changing an alternator on a '09 sedan with a 4.6? I'm helping my son next weekend and can't find any info on it.
Thanks

I don't think many have failed. Be careful that you replace it with a reman OEM or new OEM . I think it is a 150 amp alternator. Do not us a lower amp. The car has a lot of electronics to power.

I got it done and it wasn't as bad as it looks. Took about 2 hours. The alternator has to be unbolted from the bracket and then the bracket unbolted from the engine. The alternator and bracket can then be lowered and removed through the bottom of the car. I took a couple pics of the bracket. The first two 14mm bolts are easy to see (from under the car). The 3rd and 4th are concealed by the alternator. The alternator needs to be moved forward towards the radiator to get at them.
(Not pictured - there is also a 12mm bolt on the front of the bracket- towards the radiator)

Good pics. Curious, did you end up using an OEM or aftermarket unit? Mine is in the shop now for the same problem, dealer told me it would take several days to get an OEM unit, so I might have no choice but to use an aftermarket one supplied by my indy mechanic.

I put in a new OEM from Hyundai. It was $341 delivered to my home in 2 days.

Nice price, my dealer wanted $429 (I'm definitely trying to get it online next time; by then I'm more than certain I'll have a garage toy I can use as a backup).

Good idea. Those online sites are run by Hyundai Dealers and sell the exact same OEM parts.

Could we not go ahead and put in an aftermarket HI Output car audio one? If I pay that much again for an alternator (I JUST put in an OEM Honda Accord in my 08 accord for that PRICE) I think that is the route I go!
HI Output Alt
Now the site does not have our car BUT I think the Mustang 3.8 has the same structure as ours. For the price of a 150 OEM one why not get a 240 AMP for the same price??? Would it hurt us?

The mount is different than the one in your link.

Here's a quick pic of what ours looks like...

Thanks for the pic. Maybe I can reach out to check the availability and maybe make a sticky.

And that's what is crazy about it too, there was over $100 difference between online and my dealer! Same part!

You guys said to push the alternator forward after removing alternator bolts. I cant get the thing to budge at all to get to the other 2 bracket bolts
