What is the process for changing serpentine belts on
2014 xjl supercharged 3.0
thanks

 

timatayo, you will need a decently sized 1/2" drive breaker bar. From there, if you look on the tensioner, there should be a square on the arm. Insert the breaker bar into the hole and move the breaker bar such that the pulley on the arm moves away from the belt. WIth the tensioner arm backed off, find a near pulley and slide the belt off of it. You can now release the breaker bar slowly. From there, you can remove the old belt. Having a second person for the next part is helpful, but not required. You are going to take the new belt and route it like the old best was, leaving the belt off of that pulley that is easy to grab. Have the second person keep tension on the belt to make sure that the belt doesn't slide off of any other pulleys. Now you are going to again use the breaker bar to move the tensioner pulley away from the belt. Use the second person to slide the belt on to that last pulley. Release the break bar slowly.

If you are having to do this by yourself, finding a pulley that the belt will hang near but that you can also reach as you are pushing on the breaker bar is the trick. I have found that using some tape to hold the belt in place can be helpful.

 

Top Tip!

Take a photo before you remove the old one! It gives you a fighting chance at routing the new one correctly. I messed up once on the XK8 and snapped the new belt within seconds.

Concur with Thermo, it is possible to do it on your own but two pairs of hands is way easier.
