    I am changing the water pump on my 2000 5.3L and having trouble with the water pump pulley spinning when trying to remove the fan nut. Does anyone have any tricks to remove the fan? Thanks in advance.

    Just take a rubber hammer and strike the fan blade nut counter clockwise with a wrench on the nut facing the engine. It'll spin off fan blade and nut together.

    Got it. Put vice grips over the belt and pulley then tapped the cresent wrench with hammer and it came off. Thanks for everyone's help. This site is great!
