serpentine belt
need some help, 99 F-150 V6 with 105,000miles, just replaced the Alternator and changed the belt. didn't loosen the tensioner just cut the belt, now can't get the belt on can't figure out how to loosen the dang tensioner, do i just pry the pulley out of the way or do I have to loosen the whole assembly and then move it back? have a haynes manual but its no help. can some body help?

If memeory serves me correctly........
Obtain the proper size socket to fit on the nut in the face of the tensioner pully. Also obtain a decent size pull bar for the socket.
It takes quite a bit of "oomph" to get the tensioner arm moved over far enough to slip the belt on. There really isn't any trick or secret. It just takes a good bit of pressure to move the pulley.
Two people makes it easier. So long as the guy with the pull bar can be trusted
edit to add: It might be that the front of the pulley has a "socket" for inserting the drive of a ratchet (1/2 or 3/8 - not sure). Either way, look at the face of the pulley and whatever you see, put something there and pull.

Serpentine belt tensioner
When I commenced my 4.2 rebuild (97), I found that the tensioner had seized/broken & the pulley remained in the last position it was placed in - in my case it was tight enough to keep enough tension on the belt to make it appear as if it was (flexing) working properly once it was rotated with a socket & breaker bar.
