Stuck Water Pump Removed with Hammer Drill (GM Family 1)
This is a stuck water pump which is a very common issue on the GM Family 1 engine because the aluminum water pump is being installed in a shaft on the engine block with tight tolerances and corrosion overtime makes it impossible to remove.
This time i had to get the hammer drill to remove it by smashing it to pieces, no heat, prying, hammer, etc worked.
