So wait.... you're saying this did not work?

Default Worked perfect! 8 year old post but worked for me. Thanks for the help.

The belt needed to be shorter and I swapped the idler pulley for one the same size but ribbed since the belt now runs over it instead of under it. The end result works so well that I can't figure why Ford went to the trouble of designing the AC/non-AC setups so differently. Here are the Gates part #'s needed to do the job.

Belt...#K080806 8 rib/81 1/8" long

Idler Pulley...#38052 8 rib/90mm dia.

The parts can be looked up here...

for all the details.

I hope this helps anyone else who encounters this all too common problem in the future. The fix is inexpensive and only takes a minute or two to swap the pulley then just change the belt bypassing the compressor and putting it over the idler instead of under it. Back on the road again

Thanks again...

Default 2008 f150

I have an 08 F 150 with the 4.6L. the AC compressor is making a terrible racket. I have already tried the serpentine belt for without AC. Following the diagram under the hood the belt was too loose. I switchedbthe side of the idler and tensioner it ran on and it was too short. If anyone has done this and know what belt to ask for I would greatly appreciate it. Thank you.
