I have a 1990 F150 Ford pickup.
Water is leaking from the water pump because some idiot drilled holes
in the pump near where the fan attaches to the shaft. There is a hole
on the top and the bottom in the pump casting. Leave it to Ford to
design junk like this. I can only guess that these holes are there
from the casting process and they forgot to patch them afterwards.
I'm going to try to fill the holes with JB Weld, but first I got to
get out all the coolant.
