HI!... Oh shoot, I forgot about that. My dealer had the same problem. They can't think. On their PC it shows no part # for the 5.4 no A/C belt tensioner. Go back in and tell them you want a no A/C belt tensioner for a F-150 XL with the 4.6. Belt should be mentioned once you find the right tensioner. They wanted too much for the belt at the dealer so I went to my brothers shop and got it for half the price.

The only # on the tensioner is this one on the back.



It reads XL3E-EA.

I went through all my dealer bills and can't find the tensioner invoice. Sorry.

 

Thanks, went on all data and found some part numbers. I will take your info and see if they come up with the part number that I found. Thanks for your help! If there is anything else that you think I need to know for the tear down, just let me know. Also, if there is anything I can help you with, I would be glad to. I have done a lot!
