Is there any difference in the serpentine belt routing of an 05 5.4L compared to an 07-08 5.4L?

Can anyone tell me which part I need to replace my serpentine belt? Or if someone could let me know where I can find all of this type of information.

I am currently looking at the Motorcraft JK61031AB V-Ribbed Belt. The notes state that it is w/ AC. I assume this is normal for the belt to include AC...?

My current belt only has about 40K miles on it but is cracking probably due to the South Texas heat. Anyone have any other tips or advice?

Need to know what engine you have

Just go to any auto parts website and type in vehicle info. It will tell you all you need to know.

Of course, sorry about that - 5.4L - its a 2006 F150 Screw Lariat.

Easiest way would be to remove the fan and shroud to give yourself a TON of room (Philips screw driver and a fan wrench), then use a 3/8 ratchet to loosen the belt tensioner and pull the belt off by hand. Easy job.

I looked on RockAuto.com and they had two choices for Motorcraft (which is what I plan on getting.)

One said w/ air conditioning and one said w/o air conditioning.

If you have AC, get the AC belt. If you don't, don't. Or get both and keep the non AC in the truck so you have a bypass belt in case your AC clutch freezes up on you on the road some day.

If you have A/C. Get that belt. Honestly, for an item as simple as the belt. I'd just go big box.

Roger - wasn't even aware they made these trucks w/o AC.. But I'm placing an order online and getting a few things so just going to get everything at once. Thanks for the help everyone!
