2004 Ford expedition 5.4 l Triton motor AutoZone duralast 780k6 works length is 77.953 you have to loosen the alternator put the belt over that last then tighten up the alternator thank you for the info
This worked on my 2008 5.4 F150, I used the 780K6 belt, it’s a tight fit and you do need to loosen the alternator to get it on but works perfectly! Thanks for the video!
Did this tonight on a 04 expedition 5.4 and the only way to get the belt on is by loosening the alternator and sliding the belt over the alternator pulley last and tightening it up, when you tighten the alternator it puts tension on the belt and works great.
MANY THANKS FOR THE GREAT TIP! FWIW to others, a belt that worked to bypass the A/C on my 2001 Ford E350 SuperDuty 5.4 Triton (w/o wasting time & $ on buying a pulley or different tensioner) is the Gates K080816 1-3/32" wide x 82-1/8" long (28mm x 2086mm)...it only takes 5 minutes to grind down the hump on the aluminum cam chain cover with a Dremel. (behind the tensioner base near the stationary idler pulley).BTW: the 81-1/8" (2061mm) Gates K080806 is too short for my 5.4. Anyway there's a pdf list online of all the 28mm wide Gates 9 rib belts with lengths & parts #'s if folks need to cross-reference different lengths.
Hi, what is the benefit of grinding that piece you mentioned? I have a 2003 e350 and got an 80.5 inch belt I got it to fit but it looks like it wants to slide off the tensioner pulley
This worked on my 2004 5.4 new style. Tensioner out of the equation all together had to take off alternator put belt around it then pry back into place with a crowbar off a piece of wood placed against fan shroud.

I'm having same problem my ac pulley seized up on me yesterday and it didn't want start... I have same year as you , Eddie bower edition same size motor.. it worked for you I need it to last till my SUV can get fixed
Thanks for the video... the belt in the video didn’t fit my 04 Lincoln Navigator. It just wasn’t long enough-too short by a few inches. I tried the 785KA duralast belt from Autozone and it fit like a glove. I ran it and it does squeak from time to time but it works...at least until my compressor gets in!!!
I used your info along with another great youtuber...... FYI your belt fits a 2011 Buick regal turbo or non turbo four banger. Works like a charm! !!!! Napa carries them! :)
beat the snot out the bearings ..... on the alt and the ps pump and the water pump.. to much tension is bad. what do you think theres a tensioner in there.. and again another video .. on this.. so now iam up to 4 diff belt sizes
Well.. Close but not quite... The expedition must have a slight variance... The belt is about a 1/2 in to short.. I can't get it to stretch enough to make it.. Im going to try the next 2 sizes up and see how it goes.. Unless there is a something else i need to loosen or do..
I'm trying to do this on a 2004 5.4 expedition, having the same problems. Anyone with a part number for a belt that works on expedition would be appreciated
Guy if you don’t want to waste your time with a pry bar, loosing your alternator and broke anything like happened to me better go to Auto Zone buy the ACDelco pulley #38009 and the belt Duralast 840K6 replace the original pulley on top of the tensioner keep the older one to later when fix your A/C then you will thanks me all your life you will only spend around 58$ both parts Good luck
This absolutely works. Anyone that says it doesn’t, didn’t loosen up the alternator. There is no tensioner with this set up so that is the only way to do it. It definitely looks like it’s an inch short, but it’s not. Take the top two bolts off the alternator mount. Loosen the bottom two bolts 3/4 of the way, tilt the alternator forward, slide the belt on, and pry the alternator back into place. Be careful, you will crack your fan shroud if you pry too hard. Works like a charm: no squeaks, silent as can be
I'm noticing it's not working for some people but for others a 785 works . With that being said if the belt is tight that I show try loosening the alternator bolts and putting it on or how I did it was manhandle it on there and I bump the engine over to get it into the grooves .
I have a question Anthony.. I am trying to bypass the AC on on 03 Expedition.. The configuration is the same yet the problem i have is the belt tensioner pulls upward (same as my 06 F150).. How did you get around that.. In the video it appears that the belt just rides under it... Thank you Jon
Mike McFadden: Watch the video on this subject posted by Kevin Thomas. The 2001 has a smooth factory idler pulley- when I tried to use an 81" belt (correct length for the existing pulleys on my 2001 F150 Supercrew with 5.4) when I used the 81" belt and wrapped it on top of the smooth pulley it did not fit correctly due to the housing behind the factory idler pulley. I watched the video by Kevin Thomas on here. I used the exact replacement idler pulley and belt he said to use and it worked perfectly. That idler pulley is very easy to switch out. One bolt to take out. I think it was a 12mm. All together it took me 10 min. to change the pulley and belt. They work on my 2001 5.4. Watch Kevin Thomas's video. All the videos are good but there are slight differences in vehicles each year. I know what worked in my 2001 5.4 and I tried 3 different belts and this is what worked. I do have a squeak in my belt, but it goes away after a min. of running. I might try some belt dressing and hope it will mesh out. One thing to remember on this fix- the new belt is 6 groove as well as the new idler pulley. The factory pulleys are 8 groove. I tried different grooves and what worked best was putting the new belt 1 groove back on the factory pulleys. Hope this helps you out.
780k is the wrong number use the 785k belt its a 1/2 inch longer...use a flat blade screw driver to pry it over the top of alternator. I got mine on 95% (grooves didn't line up correctly) of the way and to make sure I didn't mess the belt up I just bump the key over really quickly then back so it does not start and it lined it right up. Belt will rotate clockwise.
@@razorbak6783 ya I figured put the hard way lol I got er done I appreciate it... I had to loosen 2 alternator screws and bracket on top got hose over then tightened th screws back down ! Runs like a champ Now!!
*******Just to be clear, can someone let me know if i do or do NOT have to remove the ac compressor to accomplish this? Or do i need to completely remove it and then put the shorter belt?
Thanks doctor.. my 2004 ford f150 fx4 5.3 ac compressor bypass surgery was a success..

hello a question did you have to remove the ac compressor?
I took off driver side lower idler pulley listen alternator only then I could install the belt. And it works great. Thank you for the help!

Sorry I actually use the belt number 785k6 not the 780 case 6 on a 2004 Ford expedition 5.4
I have a 2003 ford expedition eddie bauer 4 wd and this looks the same as my 5.4 thanks ill find out if it works
Roger Mitchell did it work!?
This is bull. They leave out the work you need to do to get it on. Best to change the one pully
Will this work on a 5.4l 03 expedition....desperate to know!
Anthony my pickup is ghe same 2004 f150 5.4. Ac not working the right polly dont fit plz help because the idler could fit
Well.. Close but not quite... The expedition must have a slight variance... The belt is about a 1/2 in to short.. I can't get it to stretch enough to make it.. Im going to try the next 2 sizes up and see how it goes.. Unless there is a something else i need to loosen or do..
J. Rich Did you figure out which belt it was? I'm trying to do the same too.

Will this work for a 2002 expedition?
Politely, this does not work on a 2006 F150. Just a heads up.
Noup!!! It doesn't work on a 2004 Lincoln Navigator 5.4L ...
is too short!!!!
It's not working on my 2005 f150 ford can you do a video of how you put the belt on each pulley ?
I'm noticing it's not working for some people but for others a 785 works . With that being said if the belt is tight that I show try loosening the alternator bolts and putting it on or how I did it was manhandle it on there and I bump the engine over to get it into the grooves .
@@anthonynorris2818 it's real tight like it lack a inch more to fit over last pulley.
Didn’t work for me.. too short.. 2005 5.4l 4x4 f150 king ranch.. but got the right belt.. 6k790 master pro belt from O’REILLY AUTO PARTS
Do you think this would work on an 04 same model?
Anyone know what size belt to use for a 4.2 v6 2002 f150? Searched everywhere. All these specs are for a v8
Didn't work on my 08

Did you ever get that belt to bypass your a/c compressor? I too have a 03' 5.4 Expedition
is this the newer body style or older 04 was a split year right?
The belt part number is not correct it is a 785K6 the 780K6 that he is showing is too small
I just installed the 785K6 on my 2004 F-150 4X4 with 5.4
John Dougherty wits the size difference between the 2??
will the belt work on a 2001 ford expedition 5.4l

OK.. But there is enough tension to keep it tight??
Great.. Thank you very much for your time.. Much appreciated..
Can someone show me a diagram on how it routes
whats the belt size?
Don't fit I 2007 f150.... unless there is some secret way to put belts on..... I couldn't do it
780k is the wrong number use the 785k belt its a 1/2 inch longer...use a flat blade screw driver to pry it over the top of alternator.
