My 1999 Cadillac Deville was leaking coolant from the bottom of the water pump housing. It has a Northstar Engine and uses a special removal tool to remove the pump. I bought a replacement pump which consists of a two piece movable inner vaned shaft within a fluted collar. I've managed to use the removal tool to expose the vanes of the old pump but can't get the fluted collar out of it's housing. How can I do this without stripping the inner housing threads?

Drain cooling system. Move engine torque strut for access. Remove air cleaner. Remove water pump belt cover (4 bolts). Remove water pump drive belt, by-pass hose, lower hose and pump cover. Using Remover/Installer (J-38816), rotate water pump assembly clockwise, and remove from vehicle
