agreeing with this i would reccomend going stock or heavy duty water pump and maybe try to find a dual fan set up or even try running it with the hood off. theres many things it could be. you could be either loosing coolant or possibly your coolant is flowing to fast for it to bee cooled down in the radiator i would contact an auto parts store of if u have a friend whos a mechanic just ask for suggestions
