Sounds like you need this one

Guy over on lost had the same problem. I believe he came to the conclusion that they used different tensioners throughout the years.

Yeah, it's weird that they have different part numbers, but this is what's on my mother's '05:

And I checked a couple of sites (NAPA and Checker) and they do call out the same belt for both the 3.7 and 4.7. Don't know whats going on with the different part numbers, maybe they changed the size just slightly or the belt composition?

EDIT: ok, never mind. After reading Blake's post that makes more sense, I'll check it out later. Gonna go do some Christmas shopping right now...

Do I need to spray them with anything so they go in easily? Or just squeeze/replace and call it a day? Also it looks pretty tight in there.

Just take a socket (15mm I think) and rotate the tensioner pulley to loosen the old belt, pull it off, put the new one on and life is good. Just follow the threading diagram if it's still on the metal cross-member above the radiator, if not let me know and I'll post it up.

 

[hyde]

Yeah, I remember seeing a diagram, but mine is all dirty now. Also a picture of the spot where I need to loosen would also help.

OK, here is what you'll need to replace your serpentine belt:

1 - 15mm socket on a ratchet or break-over handle. The socket I show is a deep socket but this is not critical.

1 - replacement serpentine belt, Mopar #53032037AK or equivalent.

First open the hood and find the tensioner pulley:

Then take your socket and place it on the center bolt. Rotate the handle clockwise, the tensioner will rotate up and in:

Now remove the serpentine belt from the tensioner pulley, then release the tensioner pulley. You can now remove the serpentine belt. Following the diagram:

place the new serpentine belt around the all but the tensioner pulley; the grooves in the belt will fit in the corresponding grooves in the pulleys. Rotate the tensioner pulley up and in one more time and thread the belt around the tensioner pulley then release the tensioner. Visually inspect the belt one more time to make sure it is threaded properly, then start the engine and verify that everything is turning properly. There, you've changed you serpentine belt yourself and didn't get ripped off by a dealer

And for clarification, although I specified making the tensioner the first pulley to remove the belt from (and the last to place it on), this is not completely necessary. Another good first/last location is the idler pulley located just to the right of the tensioner pulley. As long as the belt is properly threaded around all pulleys you will be fine.

Man, those 3.7l's without the bigger shrouds are empty! I bet its easy to change the oil from the top!

And I was sitting here looking at Corwyyn's pic thinking "why is his motor sitting so far back in the engine bay".........duh......then it dawns on me that I have the "monster" fan shroud too.....haha

[hyde]

I think only LTDs have it?

Kevin, thank you so much, those are great pictures.

Yeah it's not too hard to get to the filter from the top. Reminds me I need to do an oil change this week along with some other maintenance items.

No problem Huseyin, I think I may copy that over into a thread in the 'How To' section since I didn't find one already in there...

 

[Dave]

Corwyyn's pic and description should be a sticky or a how-to.

Nice write-up and pic's Corwyyn.

Dave

 

[hyde]

Yeah, look at that filter, it is right there...
Where is the oil drain plug?

 

[JeepJeepster]

Back of the engine on the bottom.

 

[hyde]

So you still need to get down under there, anyhow.

 

[Dave]

Yes, so I just do mine from the bottom since I am down there anyway.

Yeah, unfortunately that's one thing that stays the same

 

[hyde]

I think everything would probably pour right into my eye!!
So, you drain first, then replace filter? or Pull filter first then drain?

 

[Corwyyn]

I always drain first, replace the plug then move the catch basin over and pull the filter.
