2002 4.7 overheating
I am new here so I hope that I am posting in the correct place. If not please direct me to the correct spot for my question.
Ok I have a 2002 4.7 magnum 1500 single cab pick up. I love my truck but for the past few weeks i have been having issues with overheating. I do not have any experience with mechanics but I am very mechanically inclined so I started a bit of research and just kinda started to trying to eliminate possibility. First I pulled the thermostat to see if that was keeping coolant from getting through but still had over heated. Next I replace the water pump cause the weep hole looked like it might have had a bit of coolant coming out, still no success. then I noticed that the fan was not speeding up when I would pull the throttle. so I replaced the fan clutch, now It is cooling much better and I can get around town but if I am on the interstate or moving for a extended amount of time it starts to over heat. I have not allowed it to get to redline but it gets close. I have burped the engine twice by starting it cold with the rad cap off and letting it warm up also squeezing the upper rad hose. and letting it run like this for about 30to 40 min. also replaced the rad cap just to be safe. Ive checked the oil and it does not apear to have any coolant in it and I am blowing no white smoke.. no smoke at all for that matter. I am at my wits end and to broke to bring it to a garage. Any one have any thoughts or suggestions on what might be going on?

would cool spots on the radiator be a sign that the radiator is bad?
Also I just remembered one of the times I drained the system I got a bunch of sand looking crap in the drain pan. But I have drained it again since and have not gotten that again.
Thank you for your response.

Did you buy this truck new? If not, how long ago did you buy it? I ask because of the material you say (sand like) came out of the rad and into your pan. maybe someone used something like top leak?
As for cool spots, the indicate a spot in the rad where it is blocked and coolant not flowing through it
