I have a coolant leak and its the water pump, how hard is it to change the water pump on a 97 blazer 4.3 vortec? Is there any how to videos? Thanks

 

Go to forum index and in DIY look for thread on this.

Also this is a pretty good video on the general procedures:

I'm not real sure about the bolt thread direction on the idler pulley though.. be aware!

BTW: Why does a body lift require spacers between upper and lower fan shroud?!!!! Doesnt make sense to me

Added:
D'oh! {facepalm}

 

think about it, body lift raises radiator, fan remains at same level....

 

Thanks ill be sure to watch it!
