2005 Isuzu Ascender 4.2 six GM engine Fan clutch replacement. I believe reversable threads for removal. However the shaft it rides on spins with wrench. Can you lock and how for removal. Also fan guaud around fan tight fit. Does all have to come out at on Old timer working with newer. Was not this difficult in 1980"s helping neighbor with not a lot of money.
Thanks
