replaced the water pump, thermostat, and flushed it all out. still running hot. ran good for a day, now not so good. did i miss something?

 

Get it warmed up and feel the hoses going to your heater core,if they are not the same temperature then you have a blocked heater core.

 

crack in the radiator possibly? same thing was happening to me and that was the problem.

 

heater core. i do think thats my problem. thank you.
