Ok so, any help one could give would be grateful. I have to attempt to install my serpentine belt, since mine came off in downtown mid rush hour somehow.. anyone have any advice for me? Like where I could possibly find a diagram? Its a 2005 Jeep Grand Cherokee Laredo, 2wd 3.7L v6 with AC

Often there is a label under the hood. Otherwise, try reading the owners manual.

as stated , the routing label is under the hood . If your belt just broke , i would check your free spinning idler pulleys and make sure one isn't siezed .you will need a basic socket set and a breaker bar helps too if you can fit one in there with a socket on the tensioner bolt.Your not undoing a nut , the tensioner will move in an arch under spring tension .I think its almost center of the engine to the right f the AC. also put your socket on and make sure the tensioner moves freely before you start. I like to route the belt first by sticking an end loop of belt down and around the big crank pulley then hold one side of the rest of the loop in each hand .follow the routing label untill i end up at one of the smooth idler pulleys so i can just pull down with one hand to keep tension on the belt while i put the socket on the tensioner . rotate the tensioner and slide the last bit of belt under the smooth pulley . That's the best i could do for instructions . I assume since your asking , you've probably never done one so i tried to be as descriptive as possible .
Good luck

All good advice! Thank you! Unfortunately under my hood has no diagram, but the package my new belt came in did. I checked my pulleys and one of them is stuck. Thankful I had that advice before I put the belt on. Would the tensioner be the really big pulley that spins when the motor is running?

no, that one is your main pully that makes everything else turn when the belt is attached.

if you don't have a belt and you start it. The only thing that will turn is your main. If you have a belt. Everything turns.

Alright, once I finally got the pulley to replace and actually got motivated to get to work this was less than a 5 minute job. Thanks for all of the help, im sure I would have struggled for a while wihout it. Especially trying to put the belt on! This is why I love JeepForum! I plan on doing the lift soon I pretty much guarantee ill be referring to my previous post for help lol.
Thanks again, everyone.
