Along with a new water pump should have come four new studs that first need to be screwed into the fan hub plate on the water pump using the double-nut tightening technique.
Careful not to over-tighten/twist-off any of them.
If you don't have the new ones, you should be able to remove those from the old water pump, again using the double-nut technique, but doing so might not be that easy. Loctite may have been used on them, so penetrating oil and/or heating might help.
This all sounds too basic though, so how about a photo(s) of your problem parts?
