How did you test the water pump? Is your radiator fan coming on? They usually kick in just under 210 but every vehicle is different. Make sure the radiator fins aren't clogged with bugs/ dirt or that there aren't alot of bent fins. There is always the possibility that the radiator is restricted internally also.

thanks - i tested the water pump by having it run the bleed cycle in accessory position temp up to hi and fan on low then you hold gas pedal down for 10 seconds then the pump kicks on and runs a 7 yo 12 minute bleed cycle which it does without a problem so i am taking that as proof that the pump is working OK. radiator is clean and has no dents or damage. any other thoughts?
