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.

Any help on a 2001 Cherokee Sport 4.0L? Just bought a dayco w/o AC serpentine belt til I can afford a compressor. Don't know if I wanna go the used route. Got a 120K miles on my truck already.

@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)!

Sweet, Is their a great deal of difference between the 07 and 08 4.7? One has 230 hp and other has 305 hp. Looking to get a used commander, gas prices r at 3.00 per gallon in California, no hemi, but the 4.7 looks like a good choose. What do you think thanks bro

[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.

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

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.

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.

@jbrunsonjr Sweet, I think you are right, 70 hp is a great deal of power.

@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!
