Thanks so much! I have a 2001 ford f150 and it has the same alternator as yours. It has the exact same set up as yours. I followed your video step by set and had the new one in in a few hours. No complaints here! Great!

Thank you! Very clear and helpful. I'll be doing this tomorrow morning on my work truck. Now I know exactly what I'll need: 10mm, 13mm, 15mm and blue loctite. Done!

Did mine today thanks to this video. No need to remove the radiator hose, its not really in the way you can work around it easily. The old bolts had silver anti sieze on them so this job was done before by someone, so they came out easy, I dont think they need loctite

I wish more people did this. Thanks for the info!

Thank You, its so hard to find 4.2 engine info, I appreciate Your Video !!!

Thank you sir. @2:10 That trick on the tension for the serpentine belt would have taken me days to figure out. i had the thing done in 18 minutes at best. Big thumbs up.

I left the radiator hose in place. I levered it out of the way with either a pry bar or a piece of wood. My F150 has no A/C, so my alternator was much more accessible. The routing of the serpentine belt on my F150 is different without AC. I bought a 25 inch breaker bar 1/2 drive at HarborFreight on sale. This was particularly handy at the junk yard where I got a used alternator from a junked Ford Explorer. I had to use a lot of leverage to remove the old alternator & actually broke a cheap socket early on. I needed a better socket anyway. I found I didn't have to relieve the serpentine belt tension to remove the old alternator. After the top bolt and the lower front bolt were removed from the old alternator, the old alternator could rotate clockwise. This relieved the serpentine belt tension so much it just fell off the alternator pulley. I took my junk yard alternator to an Advance Auto Parts store, where they tested it for free to confirm it was functioning OK. The junk yard has a 30-day free replacement policy -- no refunds but you can exchange what you salvaged for another you salvage. F150s are one of the most popular vehicles, and most junk yards have quite a few to choose from. I found about 80% of the junked F150s already had their alternators scavenged by previous customers. I was told by a mechanic that Lincoln Continentals and Ford Crown Victorias also have the same model alternators installed. One odd thing was that the bolts on the Explorer were 13mm hex heads while the bolts on the F150 were 15 mm hex heads. The alternators were otherwise exactly alike.

Very informative video Dan. I did this to my 2003 F-150 and it worked out perfectly. Thank you for helping me. I'm a musician and know nothing about truck mechanics. You made me very happy.

Awesome video! This is the first video I found that has the exact same alternator setup as my truck, Thanks for the help!

Haha " if I'm doin it wrong, I don't wanna hear it." Classic Dan.... thanks for the video bud.

Great video! Just want you to know that, after watching a half dozen other alternator videos, it was your video here that answered all my questions. Successful replacement job done in about 90 minutes - first-timer as well. Nice job, sir.

thanks this video has been a big help. you did a good job of showing how it's done. once again thank you

Thanks so much!!! Very clear and helpful. This is the only video I could find for my type4.2l and I actually had the same looking alternator.

Great video, used it to swap out the alternator on my 4.2L 2006. The 2006 has an additional mounting nut for the megafuse on the alternator (I assume that's what it is) and mine has AC lines in the way that were not present in this video. I did not disconnect the cooling line and was able to easily wiggle the old alternator out without removing tubes/hoses for any other systems.

Thanks, this was tremendous help, had to change mine out today. Mine took a crap at the boat ramp today.

Thank you for doing this, I grabbed a 15,13, and a 10, swapped the new one in and took the core back to the store in 20 minutes.

Did mine today and followed your steps and was done in no time, your instructions were on point and extremely easy to follow 15mm 13mm 10mm. Thank you!!! you saved me!!! and I didn't have to give my money away.

Thanks for the video, done with mine in less than an half of hour.

Came hear for an idea of what I was going to get into tomorrow for my girlfriends parents F-150. They wouldn't know the difference between a wrench and a ratchet. Thanks for indicating the size of the sockets! Much help.

just had to do the same exact thing on my truck yesterday, found it easier to disconnect the wires on the back of the alternator after it is removed, and installing them on the new one before installing it.

I copied you and it was really quick! Thanks many !!

Awesome ! I have to do this first thing in the morning in the dang walmart parking lot. This is the best informative video. Socket sizes, everything. Thanks.

My 19 year old truck f150 4.2 was not recharging. put in a 130 and a new belt by following your steps. Nice)))

The old alternator is out, could have used some deep mm sockets, but I got the sob out. Thank you many times over for posting this video, it helped me a lot man.

I love this guy I wish he did all repair videos lol if u don't like the way I do it I don't want to hear about it fanfreakingtastic love ya guy

Only difference on mine is , between the two bottom bolts on the alternator in that center hole a push in keeper is there that holds a wiring harness. Agree with you on getting that radiator hose out of the way. Gonna do mine next week and you made a very good video. Thanks!

That's exactly the video I needed! Worked like a champ.

Thanks for the Vid, gonna do this my self instead of paying someone to do it, and save myself some money.

Thank you. You saved me some time and frustration. Good job.

Thank you for this video! I couldn't find anything out there either. I appreciate this very much!

Crazy thing is I understood this video more than most I'm from Texas and damn if he didn't sound like my grandpa teaching me something growing up

Thanks, I changed the factory at 145K 10/2006. about to change again at 279880 miles Alternator 130amp is good the bearing are screaming.. purchased a life time warranty, getting it new one free... Go O'Reilly auto parts.. UPDATE, was the idler pulley right under the Alt. the bearing were falling out when removing the pulley.. $35.99 plus tax..

Great video. One of the best diy vids I have seen. Going to Auto zone tomorrow for a new alternator!

Thank you! You walked me right through it.

Your video gave me all the info i needed thankyou brother

Great video. Very helpful. Thank you.

Thanks for the how to, worked great!

I did mine today, thanks for the video ......

FINALLY a video with the same kind of alternator that I have.

This is for 2007 f150 4.2 as well, thank you sir

Thank you for making this video. Crazy that you posted this yesterday and its helping today, one day later!!

Thank you... I have the same truck... I need to fix it.

Great Video. Good info.

I have the same engine my altenater went out and this video helps alot

Thanks! Just what I needed!

Great video sir thanks I'm doing the same job this weekend!

Great video changed it out in 45 mins ..

Hey guy thank you so much.

Great tutorial - thank you!

Thank you sir more than appreciated

I don't know or care if it was right, but I did it the same way and it worked. I didn't find the radiator hose to be in the way, so I left it connected.

Thx man b8g help. And away I go..

.....I don't wanna hear it. Love it! Very good video.

Fue de mucha ayuda gracias

Excelente thank you

Thank you

Easiest ever! I didn't even bleed!!

All I did was spend 5 bucks at advanced auto for new brushes. Alternator is working perfectly again.

Looked good and I can hear it whining so ya know its putting out.

You sound like a guy who knows a thing or two. Why did you decide to install the “new” alternator with lock tight thread lock if the OEM alternator didn’t have any on the bolts? The video was great! Job 👍 well done. Keep up the great videos

Dan, what kind of indication were you getting that your alternator needed to be replaced?

thanks

hi sir Dan,i cant get the nut off of the air condition Line bolt its rusted,what do I do,i got a 13mm deep socket to,been so long since it was changed,i got a new battery and found out the alternator wasn't charging the battey,ok like to hear your reply thanks,hav a good one Dan.

A 1/2inch standard is close enough to a 13MM that you can use them interchangeably. I've only had one instance in which this would not work.

How is it holding up?

Thank you gotta 2001 V 6 ford 150 Xl

Was this on a manual transmission model?

Take alternator in before you buy. The dimensions or width of alternator matter.

Fucking excellent! Mine just shit the bed and your video was straight to the point. My only two concerns, did you unhook the battery and I'm mildly concerned about finding the bolt to loosen and tighten the belt. Other then that, I'm gonna give it a whirl

Aye man GOOD SHIT ON THE VIDEO!!!! me and my boy got that bitch out in no time thanks bro 🤘🏽🤘🏽🤘🏽🤘🏽🤘🏽😎

Just a tidbit of advice for anyone replacing or rebuilding your alternator.. When installing it back into the vehicle:: "DO NOT PUT LOCTITE ON THE MAIN MOUNTING BOLTS"... The next time you have to remove the alternator you will snap the bolts. They can be tightened without fear of them ever coming loose without the need of loctite... If you've ever snapped bolts off inside an alternators mounting holes you know it's a miserable job to get them out... Just saying.

Good video. One comment. Dont pull something by its wire. Like holding a cat by the tale. Just gonna fuck shit up. Thanks for the video tho.

But what if I think you did an excellent job explaining it? Because I do. Hehehehe

My hands are to big for this shit
