I don't know what insert you are referring to but it sounds like the water pump needs to be changed. Put in a new thermostat also. When refilling, open any bleeder valves on top of the engine until coolant comes out, then close it, then top it off. Then purge the cooling system from air pockets after that.

If you have a Northstar have the cooling system pressure tested and tested for exhaust gases in the coolant before you put any money in it. Sooner or later all Northstar engines blow head gaskets. If that's the case here you're looking at upwards of $3500 to fix it. Not worth it in my opinion! HTH. -Jim
