Okay so I have replaced the t-stat the temp sensor and the clutch fan. After I replaced the clutch fan it stopped over heating for a few days then bam it overheated with a vengeance kinda weird so so I flushed the radiator with hopes but no change I checked the oil and it looks good not milky or watered down in any way and when I run the truck with out the cap I can see the coolant cycling through so I don't think there are any problems with the water pump I have no clue where to go from here

When you drain the coolant, does the coolant flow easily down thru the radiator core? Look into the radiator at the core passages to see if there is any build up in them. Is the exterior of the radiator (the fins) clear of debris and not all bent up? Is the fan shroud in place? Did you replace the EFI temp sensor, or the guage sending unit sensor?

Are you losing any coolant. Just because the water pump is cycling the fluid doesnt mean its not bad. Multiple components inside there. Just my two cents. Check the weep hole make sure theres not any residue.

The sensor that you replaced, were was it located ?, i would also pull the radiator and have it checked out (cleaned), or if it looks original just replace it.

The sensor I replaced was right under thermastat housing and has one wire running to it that if I were to remove the gauge just drops. Is there another sensor I should be looking for? This week on my day off imma replace the radiator and the pump and the hoses cause they all look pretty old if not original parts

losing coolant with no evidence of any leaks
Okay so I replaced the entire cooling system and it was okay for a while still running hot but not over heating so six months later I'm out of coolant okay so I fill it and two days later I'm out of coolant again puzzling cause there are no evidence of a leak, could it be a steam leak and if so where would be a good place to start looking?
