I guess it helps to be 6'5 and 350lbs, I pull th belt with left hand and pop the clip in place with my right hand. in a pinch if not strong enough you can unbolt the alternator and then let it tilt forward to get belt off and on.

 

You guys ever try the belt in a 6.0 Inside an Econoline Van.

It seems like a different deal. Than the same engine a pick-up!
