Forget what I just said I clicked send to quick. I meant clockwise to loosen. I have been using the factory tool but I put a hex bolt into the end to accommodate my impact wrench

Prior to that step I use pb blaster

Next step is to tap around the outside of the housing with a flat punch and hammer in the area where the water pump cover sits

Next step is Mapp gas around the outside of the housing.

Finally the special merc tool with impact wrench.

This seems to be successful in most cases
