Since you just did some work on system, make sure all air is bled out. The system should bleed air out on its own, but may need some extra coaxing (park facing uphill so radiator is highest point in system, run engine, and make sure reservoir remains full). Then move on to other items: Check the radiator cap, it may not be holding adequate pressure or seal has cracks. Feel radiator for uniform heat, any cool spots indicate blockages reducing its cooling capacity (an IR thermometer works great for this). Also check that cooling fans are turning on when they should. (it not, could indicate a problem with engine coolant temp sensor, fan module(s) or fans.)
