Water is leaking from my engine. it looks like it is coming underneath and out of the bottom crank shaft pulley, however, as it leaks out fast it Over Heats and often the water pump makes that scheehing sound.
It began over heating a few days back. I'd add water and it would be fine. but it got worse to the point where water pours out now faster than I can add it.
Question,before I start pulling it apart, does it sound like the water pump, thus remove it, or is there another reason why water could leak from the bottom crank shaft pulley area?

It is your water pump. Next time, when it overheats, do not pour cold water into the radiator. Doing so will eventually warp the cylinder head and may crack the block. Just wait until it cools down before adding coolant.
