have you had this truck for a long time? Did you just get it? has it ran just fine for years? I think your flushing the heater core has flushed a whole lot of crap into the radiator. (you have done more than just remove the air conditioning) We also need more information, about what you did. Did you go back fairly recently and look at the post about engine overheating. Like 6 pages, and then the fella just disappeared. Usually just about the time we finally get one person all set on THEIR overheating problem, 2 days later some one else poses the same question.
