I'm doing this job in a few days, I'm also going to be replacing my idler pulley, is it counter clockwise to loosen?

[@dwcoffey]

Thanks for watching, Matt! I'm not 100% sure on the pulley bolt itself. The tensioner bolts are right hand thread, so yes, counter-clockwise to loosen. If you are only replacing the pulley, I _think_ the pulley bolt is also right hand threads.

Great job. Actually broke the tensioner arm on my 5.4. Thought it had more bolts and was gonna let anyone have it that could tow it (tensioner broke trying to change alternator ). For $100 I can get the new belt and tensioner. Already have the alternator. Thanks again for the video. Guess I get too pissed and give up when things don't go my way.

HI Dan, thanks for watching! Here's the link: amzn.to/3blSOL2 This is a US-made tensioner.

[@nicklorenz78]

Awesome video! Just wanted to say it was a pain in the ass lol iv built motors and because there is no room makes it super hard... need a 10mm for tensioner and 13 mm for the sensor that is in the way also added a pipe extender to breaker bar so you can get leverage. Make sure the belt is on ac and crankshaft from underneath the truck and use some loc tight for tensioner

[@dwcoffey]

Thanks for watching! Yes sir, this thing is a pain for sure!

[@isaacsalo2358]

I stuck a 2x4 across the engine bay, and used my ratchet strap to try and pull the tensioner to get the 2nd bolt lined up. Im going to break something before i even come close to bolting it on

[@Al-nt5fh]

thanks I like the zoom in on the three 10 mm bolts I wish you cold have shown more on the tension for the belt. where is the bolt? how much okay should the belt have?

[@dwcoffey]

Hi Al, There isn't a bolt as such for the tension....there is just a square hole that accepts a ratchet or breaker bar. On the longest span of the belt, there should only be maybe 3/4" of play in either direction.

I don't expect a reply as this vid is 4 years old but I'll give it a shot anyway. I'm starting to have the issue you've describe on here with my 5.4L v8 in my 2004 Ford Expedition Eddie Bauer. Is it an inexpensive fix if I have a mechanical do it? I can do a little work on my truck and I have but this seems a bit complicated and I don't have the tools to take this on. Also I'm not able to remedy this right away as my wife is battling breast cancer and I'm the only one working so my funds aren't all together there. Would riding around with this issue for about 2-3 more months as I don't travel far for work (about 18 miles round trip) and I don't do much driving in between cause any damage or is just going to be this annoying sound that's all I have to endure? Hope to hear from you

[@dwcoffey]

Thanks for watching, Dusty. I am sorry to hear about your wife, I'm praying for a full and speedy recovery for her. The situation with your Expedition depends on where the squeal is coming from. It could just be that you need a new belt....that's an easy fix and this video will show you how to do it, just be sure to follow the routing diagram under the hood of your car. If it is a pulley, like the pulley on the tensioner, that is making the noise, it will probably fail before too long. Usually when they fail, the bearing seizes, locks up the pulley, the engine will continue to drive the belt, so it will snap. Most of the time, the damage is limited to the pulley, but you'll be stranded wherever this happens. So....if I was in your situation, I'd try to determine where exactly the noise was coming from (be very careful when under the hood with the engine running that you don't let anything dangle into the fan or the belt) and go from there. If you are not comfortable or able to do that, then I'd get a shop to look at it. They will tell you whats wrong and give you a price, you can decide what to do from there. If they have to replace the belt and/or the tensioner, it should not be terribly expensive....I'd guess it'd be in the range of $150-$200 including parts.

Thank you man!

[@deanstuder1775]

I had trouble holding the piece in place and starting the first of three bolts. Mine has electric coils right on top of it. So I cut the head off of one of the three bolts and put the dowel piece in the center hole. Then when I lifted the tensioner into place, it had a home. Very eay to manage the two remaining bolts then. Im good with two out of three but if i had bought a longer bolt that was threaded all the way to the head, then I could have put a nut on that one for all three to be fastened to specs, easy as pie. Ford should have made that center one a stud. But they dont try to make it easy for us.

[@dwcoffey]

Thanks for watching, Dean! Sounds like a real pain, but also good job on getting it figured out and fixed!

[@AndreaCadelanoADVaccount]

hello i need to change the pulley in my 5.4L V8, basically is the one big in the bottom, is metallic. look like a simple job, but i'd like to know if i need to take out also the fun or not, and in the mechanic they ask me $900 cause over 9.5hrs labor.... it is easy job or not?

[@dwcoffey]

Hello Andrea, sounds like you are talking about changing the harmonic balancer. To change the harmonic balancer, you will need to remove the radiator and the fan/fan clutch. Then you need a puller for the harmonic balancer....not sure where you are in the world, but in the U.S., a person can rent these from the part store. Pull the balancer using the puller tool, then replace it. When you put the new one on, you'll want to thread up the bolt, tighten a little, then take a rubber mallet and tap all the way around to help it go on the shaft straight. Repeat that until it is fully seated. Good luck!

[@AndreaCadelanoADVaccount]

Dennis Coffey oh, looks like not an easy job... so the pro intervent look necessary?

[@AndreaCadelanoADVaccount]

Hello Dennis Coffey do you know if is normal if that the balance move a little when the engine run?

[@dwcoffey]

Well, my friend, I can't answer that for you. It all depends on ow comfortable you are working on things. This job is harder than changing a belt or an alternator, for sure.

[@dwcoffey]

The harmonic balancer should not move enough to be seen when the engine is running. If it is, most likely the rubber in the balancer is worn out and the balancer should probably be replaced.

[@ohiohunter5]

A much easier job if you could cut about three or four inches of fan shroud out of the way and just throw it away.

[@dwcoffey]

Totally agree, Dan! The way they have that engine situated far back in the bay and that ridiculous fan shroud......its frustrating. Thanks for watching!

that 1/2" tensioner trick saved my ass on alternator change then I just hung the belt up with a bungee cord "another trick I learned from another video" so it wouldn't fall off the pulleys and the entire alt job took me about an hour and a half. So I did an alt swap job with the exp of a 20 year mechanic simply by watching 3 youtube videos, then again im a pump mechanic / well driller by trade so mechanics and I go way back.
