Replacing the water pump
For reference to others - If you hold an open end wrench on the fan nut vertically and give it two whacks with a hammer straight down, it generally knocks it loose and it'll spin off. Need the belt on for that, works 90% of the time.
I just ended up having my friends hold a strap wrench on the pulley while i took a few wacks at an adjustable wrench. You dont need to completely hold the pulley from moving, just enoigh to shock it loose.
I know the rotation of the fan/pump is supposed to be ccw.
If I am understanding this, you immobilize the pully and turn the nut on the end 'lefty loosey'?
I may just be overthinking this.
That really helped me out.
As a note to anyone that may be searching these threads later:
You don't need to completely stop the turn of the pulley, just slow it enought that the hammer is able to break free the 'nut' on the fan.
