How old is the water pump. I have actuly had the fins on the pump errode so bad that the pump moved very little water, but enough to circulate just not enought to keep it cool. Also are the fans coming on, could be the sensor. Just one out of the box thoughts to go with the obvious, t stat, head gasket ideas. Relatively new to the sub motors , but have been around a few others for a bit. Good luck with it, hope it works out.
