Re: Water Pump Hole?

Not to worry, that is a weep hole that is to allow any water that should happen to get past the seal to not get into the bearing. That way the pump is still failing, but not as quickly!

Miraculously, at 80K+ miles my 51 200 still has its factory installed water pump still pumping silently. An important key to happy water pumps is not to span the fanbelt any more than necessary. I always run mine quite loose: when I was just your age I cranked the fanbelt on my old 50 Super down nice and tight and ruined my new waterpump in just a couple weeks. Making just $1.65 an hour on weekends the expense scarred me for life, and I still run my fanbelts quite loose.
