Alternator/Generator Replacement

[5gn-h3t]

So in my recent supercharger adventure, I've noticed how difficult it is to remove the alternator. According to the manual, one must drain the A/C system and remove the A/C compressor to get at the alternator. I have half of the engine apart and I still don't think I could get the alternator out.

Is there a simpler way to do this?

I couldn't properly torque the intake manifold bolts with the alternator anywhere near the engine. So...

I just found a simpler way. Remove the engine lift bracket, bend the A/C line into the fan shroud, gently bend the fuel inlet on the fuel rail toward the intake. Slide the clamp on the A/C line out of the way. This gives you just enough clearance to get the alternator out.

This applies to the I5 only. The V8 is much easier.

5gn-h3t,
Yes, I ran across this helpful and informative thread when researching the web to get some ideas on upgrading my alternator/voltage regulator & seeing how no one had yet posted something like this here before. As a moderator, I had to make a judgment call on whether to post a link to another site AND to remain consistent on this issue with respect to a thread that I deleted a couple months ago that had been started by another forum member, here is what I said to the member in a pm back then, "it's generally bad internet forum ettiquette to post a link to another forum unless the link contains pertinent information that is in response to a member's request for info. that can't otherwise be found in the home forum. There may be other exceptions and there is no bright line here like at other forums where it is a bannable offense. Hope you understand. Let me know if you have any questions."

IMO, based on the highlighted language above, I feel that it's appropriate to post this link to help a forum member.

If you do decide to do this, please post up your DIY information with any additional advice, so that we can expand our knowledge & forum information available on this topic.

...but your way sounds a bit easier. Let us know how it turns out after you get the new one in there.

Thank you for the link, but I already did it. I figured it out without outside guidance. It wasn't fun. I just read the thread you posted. I got my alternator in without removing the fuse box but my battery box was out.

Great job! :thumbs:

Just an FYI, it's also possible to get the alternator out by removing the intake manifold. But I don't recommend anyone ever touching that thing.

Thanks, I'm definitely on an adventure.
