Is it possible to change the alternator belt on my Roush-charged 2008 F-150 (5.4 engine) without first removing the supercharger bracket assembly? Guess I really ought to change both of them, now that I've passed 100,000 miles. The s/c belt is easy enough to change, but the alternator belt has me worried.

 

Nope. If you have the OE caged lower you need to pull it before the belt can be installed.
