IMPORTANT NOTE: Before you buy your replacement alternator - check to see if your original alternator has a 6-groove or an 8-groove pulley (see 12:15 in the video). Replace the Alternator on a Ford Triton 5.4 or 4.6 V8 engine. No matter what vehicle these engines are in, all installations are nearly the same. Learn to change the alternator on a 5.4L or 4.6L Ford engine. In this video, I change the alternator on a 2003 Ford F150 5.4L V8. The procedure is almost exactly the same for any 5.4L or 4.6L Ford V8.

Ditto what Von said. We did it ourselves (Okay, my husband did it, I supervised) on our '02 Expedition. We went through several videos and yours was, by far, the easiest to understand.Thank you, Dennis!

@dwcoffey 5 лет назад

Thank you so much, Vikki! I really appreciate your kind words and thanks for watching!

@Lavon8338 7 лет назад

never changed an alternator before. watched your video 1 time and changed mine on my 99 expedition in about 35 minutes.u made an intimidating task very simple. u sir deserve a go fund me because u save wannabe mechanics like us tons of money. thank u so much Dennis

@dwcoffey 7 лет назад

Wow...thank you so much for your comment! This is exactly what makes it joy to do videos....I'm humbled and thankful that this video helped you and I'm so glad to hear that you were successful changing the alternator! You should be very proud of yourself for tackling the job and getting it done!

Just changed the alternator on a 97 Expedition. I was watching another video but they did not show how to release belt tension. I found your video and it walked me through it step by step. Thank you for your help, greatly appreciated.

@dwcoffey 7 лет назад

Yes sir! Thank you Bill. I'm glad it helped and thanks for watching!

@genemccormick7567 4 года назад

Your right the voltage regulator stops overcharging battery. I picked up a Alternator at auto wrecker for $50 and it works well.

@dwcoffey 4 года назад

That's great! Thanks for watching, Gene!

I see your video has been out a couple of years but I would like to add a couple of comments. I see that someone has already commented that you should always disconnect the negative terminal first and you won’t get a spark or short out anything. Also it is a good idea to invest in a computer memory saver. I have one that plugs into the ALDL data plug (for the OBD-2 diagnostics). It came with a long wire that accepts alligator clamps or cigarette lighter plug to connect to an adjacent car, both included. I’ve used it doing alternators, starters, replacing vehicle batteries and didn’t have to worry about the engine running smoothly or the tranny not shifting properly after I had the job done. I keep an old small 12 volt back-up battery from my homes phone system that I put on the floor of the vehicle and clamp right onto it. Keep up the good work, your videos are very useful.

Where is the busbar located my alternator only had two wires plug-in the new one has three wires 1 is hot one is ground that my white wires supposed to go to the bus bar where is the bus bar? Or do I need it?

@bobhayes8750 7 лет назад

Thanks Dennis, replaced the alternator in my 2001 F150 5.4L all OK, your video is a great help. Your admonition to double check the belt seating before starting up was critical - I closely double checked and discovered the belt was not seated properly on one of the lower pulleys! Used a new DB Electric 130A ($77!) we'll see how it does. Thanks again.

@dwcoffey 6 лет назад

Thanks Bob! I should have mentioned the pulley at the beginning of the video so folks would know ahead of buying the replacement.....I did put in a comment about it in the video description. Thanks again for watching!

@huascardesullorqui7313 6 лет назад

Safety first: never disconnect the positive first, make sure you start with the negative terminal , disconnect it and then wrap the terminal cable with a towel When training safety gloves and googles are a must

@dwcoffey 6 лет назад

All good points and duly noted Alex. Thanks very much!

@Blktxdom2004 5 лет назад

Had the unfortunate experience with buying the wrong alternator. I’m getting a replacement alternator ordered.

@dwcoffey 6 лет назад

Thanks for watching Chad! How did the replacement go? I hope you were able to get it done and save some time and money! Thanks again!

@genemccormick7567 4 года назад

Best video ever. Should you replace the attached voltage regulator since that could be the problem rather then the whole alternator?

@dwcoffey 4 года назад

Thank you for watching, Gene! That could have possibly fixed me up, but I knew the alternator I replaced was a rebuilt one. Since the remanufacturers don't normally replace the voltage regulators, I opted to replace the whole thing with a new one. :)

@playroomcreative 6 лет назад

Nice video but I wish you had mentioned the part about making sure it is a 6 groove pulley instead of an 8 groove at the beginning of the video. Of course they sold me the wrong thing and now its already installed.

@dwcoffey 6 лет назад

I hope you got that all worked out...thanks for mentioning it. I added a note at the beginning of the description for the video to point out the pulley issue.....I agree, I wish I had thought to mention it at the beginning. Thanks for watching!

@wyrtwister4260 7 лет назад

I would think if the parts store determined the correct belt ( width ) for the application , they could tell the pulley ( 6 0r 8 ) groove ? Thanks , :-) Wyr God bless

@dwcoffey 7 лет назад

Good point and you would think so, but normally they will ask you if you need a 6 or 8 groove belt. I think the issue is that belts are typically inventoried by belt length........both widths are the same length, so unless you are holding the alternator in your hand (so they can see the pulley), they don't have a good way to tell which width belt you need. Thanks for watching and commenting! I really appreciate it.

@MrPuroylan 8 лет назад

Good video! Is it the same for a 2004 Ford Expedition 5.4 L? Thanks

@dwcoffey 8 лет назад

Thank you! Yes, it should be identical. All of the modular 5.4L engines are very similar, with just a few minor variations in alternator mounting brackets. An Expedition, should be exactly the same as my F150.

@MrPuroylan 8 лет назад

Thank you! I will change my Expedition's alternator next weekend. I will let you know how it goes. Cheers!

@MrPuroylan 8 лет назад

Hey Dennis, forgot to tell you that I changed my 2004 Expedition's alternator without any issue. It only took me 45 minutes to do it with the help from your video. Just want to say thank you very much! Keep posting helpful videos! Cheers!

@dwcoffey 8 лет назад

I'm glad the hear it went well! Thanks for letting me know.

@getmymail2676 7 лет назад

Excellent video! What editing software did you use?

@dwcoffey 7 лет назад

Thank you very much! I appreciate you watching and commenting. When I did this video, I used a program called Wondershare. I've since changed to their latest called Filmora. It makes video editing very easy and it has lots of built in features.

@jayb7282 5 лет назад

Is this the same on an 02 f250 superduty??

@dwcoffey 5 лет назад

Hey Johari, thanks for watching! If you have a 5.4L or a 4.6L modular, it will be the same or very nearly the same. All the 5.4 and 4.6 modular engines are nearly identical. If you have a different engine, the alternator mounting and belt routing etc will probably be different. The wiring will be nearly the same though.

@jayb7282 5 лет назад

@@dwcoffey ok thanks for such an information video 👍👍

@scidav87 7 лет назад

What socket sizes? I have to do one on the hwy

@dwcoffey 7 лет назад

As I mention in the video, my truck takes 10mm to remove the intake cowling, the alternator mount bolts and the hot lead lug. My truck is a 2003 F150. If yours is a different vehicle, it might be slightly different. I would take my socket set and a set of wrenches if I had to do one on the side of the road.

@Command37 8 лет назад

YEAR. YEAR. YEAR. Year of the truck on video title please.

@dwcoffey 8 лет назад

+Command37 The modulars are all the same, that's why there's no reference to the year.

@snap-off5383 3 года назад

If you have the 5.4 iron block 4 valve that comes in the Lincoln Navigator the manifold is different and an obstacle. Hope you don't mine me pasting a link to a video example of that one specifically: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RkNtwd-wdTI.html
