Build your ait right up , turn truck off.
Turn your key on , don't start.
Open hood , grab a 3 foot or whatever bar and a hammer . It should not take much.
Smack the fan clutch a few times and you should hear it release .
It should free turn by hand .


Make sure before you do this you make sure you are getting air to the clutch first .

The truck starts twice a year now and doesn't stick.
