Mekanik Posted February 20, 2006 Share Posted February 20, 2006 I need to replace an alternator ( single alternator on top ) on a 04 F Series tomorrow. Are there any shortcuts getting to the belt tensioner or do I have to remove the fan stator? Quote Link to comment Share on other sites More sharing options...
G. Bedford Posted February 20, 2006 Share Posted February 20, 2006 As part of the tensioner there is a small lever that will hold the tensioner so the belt is slack. Feel around below the pulley with your hand to find it. While standing at the pass. fender pull the belt towards you with your left hand, this will collapse the tensioner. Now with your right hand, reach under the tensioner pulley and flip the lever up and hold it there. Now slowly release your hold on the belt(while holding the lever up) and the lever will jam against the tensioner holding it slack. Flip the belt off the alternator pulley and change the alternator out. When you get your new alt. on, just yank the belt at the center span you held earlier and the lever will drop and the tensioner will be tight. Sounds harder than it is.

Torqued_Up Posted February 21, 2006 Share Posted February 21, 2006 What JiM said... I find that taking that air deflector off of the fan shroud gives you more room to work and you can also find that little tin lookin lever he mentioned. Oh I also get a little barbaric with the belt because for some reason I cant wok my ratchet in the sensioner so I use a long prybar against the head and push the belt out from just under the alternator until the tensioner is fully extended.

Keith Browning Posted February 21, 2006 Share Posted February 21, 2006 I don't remember why I made this but I am glad I saved it! Picture 1 shows the "little tin thingy." If you release the tensioner all the way you an push that lock into the position shown and release the tensioner. The lock will wedge in the tensioner HOLDING it in the released position.
