How to Change Your Serpentine Belt, Jeep 4.7L

A quick tutorial on how to change your belt on a 2005-2008 Jeep Grand Cherokee with a 4.7L V8 engine. The only tool needed is a 15mm wrench.

Yeah your last line said it perfectly “never pay anyone to do this job”, most mechanics would probably charge $100+, if not even more than that, for such a quick job. My 4.7 even has a diagram under the hood showing how belt fits. Just wanted to see exactly how & this video showed it perfectly. Your 4.7 sure is looking nice and new, mine just looks like a pile of dirt and rust, but still runs perfectly with 250,000km and never left me stranded once, great, reliable motors that’ll run forever

[@CSXCONDUCTOR50]

You showed the way… PERFECT!! My 2005 Jeep Grand Cherokee Laredo just turned 100,00 miles. So the time was right to renew the belt. I purchased a DAYCO Poly Rib belt at Advance Auto for $28.00. I used a 1/2-inch drive breaker bar with the suggested 15mm socket & the job went smoothly. The longer handle of the breaker bar made moving the tensioner easier. Thanks for your help.

Great video, Just changed the belt on my 2005 Jeep 4.7 with no worries of screwing up thanks to your vid... Thanks for the teaching...

[@gd9704]

Wow, you took all the fear of this job away.....really a no-brainer. Thanks for the video!!!!!

[@Miri87]

Thank u thank u!! I was able to follow it and did it all by myself.

[@vasylvasylenko7358]

Folow what?? The only thibg he showed is how to release

[@jbrunsonjr]

Glad I could help! It is definitely a 15 minute job - even if you have never done it before. It's one of those things that after you do it for the first time, you look at it and thing, "Wow, was that it? I pay someone to do that?" : )

[@o0opizo0o]

Awesome tutorial. I used it to change the serpentine on my '95 Grand Cherokee Limited. Thanks!

[@jbrunsonjr]

Thanks - glad you found it informative! No coolant spray - I did some four wheeling in some red clay soupy type mud and it got all over EVERYTHING. Check out some of my other videos to see me slopping around in the mud and then cleaning the engine off (before and after).

[@jbrunsonjr]

I don't know about that, but I had to learn the hard way, and if I can save someone the time and energy and show them the right way to do it with as minimal tools as possible, It'll be worth it!

[@CompuDirectMyrtleBeach]

Perfect, you saved the day.

[@frankenstein04]

I'm doing it on a 96 Dakota...but I have watched a bunch and they are all the same...except for your video...your video is different. As the other videos show you how to put it on and that's it you show the wear and tare on the belt to show us what to look for. I like at the end you say "don't ever pay someone to do this its literally a 3 min job. That's very admorable....someone trying to do a bunch of strangers a favor by saving money. 5 stars and Sub'd and Shared. Thanks for the video.

[@78rsantos]

It's hilarious when I hear people say "It's a 3 minute job" and then like you said in the video, you wrestled with it for 20 min. I've never been able to put a belt on in 3 min. either. Good video though.

[@marianobruno7491]

3 min is to just put it on :D not removing the old one, pick up the tools and does not include all typical problems, like your wife asking you to cut the grass or your son complaining about the climate

[@bowtechlover1]

Thank you sir!! My jeep exactly like yours overheated tonight. It's prob my serpentine belt now I know how to do it!! Thank you bud!!

[@Poppi_Weasel]

Did changing the belt stop it from overheating?

[@jbrunsonjr]

@TimeKoder13 - All depends on the cost of the compressor - if you can score a deal on lightly used one and don't care about it lasting more than 50k miles, I would suggest do that. That 4.0 is a great little engine and can rack up some miles if you take care of her. If you aren't sure what size belt to get, you can always run a string around where the belt goes and measure it/then tell the parts guy. Anywho, keep me updated - I love all things Jeep (this is my third)!

[@alanator25]

Awesome video! You made it look easy. I'm gonna go change my belt now! If that's supposed to be replaced at 60K then I need to do mine twice since I have 120K miles on mine! Haha.

[@seanfasone]

Hey, thanks 4 showing me where the adjustment was. You won't have to wrestle with it if u go underneath and push up on it with the socket.

[@azmendozafamily]

hehe, "I'm not gonna bore you with ten minutes of me wrestling with the belt... ok, so I wrestled with the belt for 20 minutes..." Classic!

[@dp_rck_channel534]

I have a 2005 Dodge Durango with the 4.7 v8. I was able to take the belt off but didn't know how to get the new belt on. After watching this, it made it a lot easier. Also, how good are the days I polyrib belts?

[@jbrunsonjr]

@NessaR2975 You're welcome! I am glad that it helped someone!

[@wkdravenna]

Thanks for making videos partner. Help me work on my Commander.

[@jbrunsonjr]

@LerdoBurgerPimp - If I am not mistaken, that is the year they did bump up the HP. That kind of increase is definitely noticable. If I had to do it all over again, I would have just ponied up the extra couple grand for the Hemi. If the prices are the same on the 07 vs 08 4.7L, then I would definitely get the 08. The 230hp is OK, but if you are like me, you will greatly appreciate the extra 70 ponies. This is a 5600lb vehicle after all! Also check out the site wkjeeps.

[@ricardogomez7301]

Hola Jack, excelente video, muchas gracias!!

[@jbrunsonjr]

Yeah, overall it was in really good shape, but I had 60k miles on it and it was the recommended time. If it wasn't still under warranty I'd let it go longer, but knowing my luck, that would have been it! : )

[@PsionNinja]

don't forget....this is the time to check all your pulleys to make sure their bearings are good.

[@cwise7]

thanks

[@WelderDude]

My belt just disappeared on my way home today. Mile from my house and lost power steering and the battery light came on as well the Trans temp started to raise. I’m guessing I gotta start with a new belt, gonna change the oil and filter, and check trans oil. If that was low would it cause belt to break off?

[@michaelwaxter3372]

Isn't there another belt in front of this one? Alternator belt maybe?

[@jbrunsonjr]

Great point!!

[@jbrunsonjr]

OK - that is funny. Yeah, trust me, it is a $20 and 20 minute job (and that includes opening the hood, getting tools out, then putting them all backup!)....

[@YosiNaturalGuerrera]

Hi. You mind providing me the tip on how to lift up the tensioner pulley to remove the belt?? I have been doing the same thing I see on your video and it does not work, the bolt in the center is actually getting to tide up. I rented the tension tool at AutoZone. I appreciated it!

[@jbrunsonjr]

You have to remember that the pulley will rotate around the mounting bolt that bolts to the block, a lot like the earth rotates around the sun. You aren't trying to rotate the pully, but the entire assembly, which pivots further down from the pulley. I really hope that makes sense - kind of like a picture it worth a thousand words. Wish I had gotten a better shot of it when I did it.

[@YosiNaturalGuerrera]

@@jbrunsonjr You did awesome! Only your video got me figured out right after I make the comment to you lol. And after watched many tutorials lol I appreciate it!

[@ciscoortiz855]

So wait did you or did you not remove fan?

[@michaelerdakos3436]

Thanks yo.

[@adlsp]

I've got a 4.7L 2006 Grand Cherokee Limited. Does anyone know how to remove/replace the PCV? This is the NEW location (not on the oil filler tube) ... it's on the drivers side and under a cable bundle and very hard to get to. I read that it has to be unscrewed ... is this true? Someone also mentioned a "large socket" if so what size? How do you do this job? Appreciate the info/help.

[@abrahamleo3213]

great video thank you for teaching us,, and donnafabEsq is right show us more like the water pump or thermostat if you have the chance, again thank you i will try to do it on my own,

[@jbrunsonjr]

Anytime!

[@trentpearo6329]

What size belt

[@Alibabaa711]

👏

[@jbrunsonjr]

It's mud from NC that stuck like snot to it. I'll probably have to steam it to get it all off. Looks like junk, doesn't it??

[@jbrunsonjr]

@LerdoBurgerPimp I say go for the newer version of the 4.7L for it has a lot more HP. You can go on the website called WKJeeps and it will explain all the details between model years. I say get it and wheel the pee out of it!

[@doublewide420]

@78rsantos lmao when someone tells me 3 min job,i start worrying,lol.

[@ameeralhelo]

What is your opinion about 4.7L engine??

[@1glopz]

Some time late but the same 4.7 is in the ford E-150 mine is at 345688 and going strong yes I do use mobil one synthetic extended milage

[@isaakwelch3451]

I doubt that ford and jeep shared engines unless you swapped an engine.

[@gunnmarcusantonio]

I changed the belt and now my jeep won't crank. I'm hoping its the battery because the battery light came on.

[@Poppi_Weasel]

What happened...?

[@gunnmarcusantonio]

@@Poppi_Weasel it was the connectors to my starter

[@Poppi_Weasel]

@@gunnmarcusantonio thanks. Good info.

[@Poppi_Weasel]

@@gunnmarcusantonio did u have to replace the connectors separately? Or did u just knock them loose & just reconnect them?

[@gunnmarcusantonio]

@@Poppi_Weasel after several cut offs I changed the connectors. There is a problem with the starter connectors with that jeep

[@davidvillegas5304]

No mostraste nada

[@Bulletinjection]

do it on a 01 grand cherokee 4.0.... lol shit is impossible

[@donnafabEsq]

Ok, now do the water pump so I can see how. :)

[@bladerunner2434]

This is always a two person job.

[@vasylvasylenko7358]

Wtf tou didnt even show anything

[@jbrunsonjr]

Feel free to make a better video to help others, then. PS - your punctuation is amazing.
