    Cooling down when moving tells us that either the radiator or fan isn't up to scratch.
    I don't recall if you replaced the rad on this, but if not it could probably do with being taken to a shop for rodding out to clear the tubes.
    You will probably find that 30 percent of the tubes are gummed up.

    Also check that your fan is still in one piece, i.e. it hasn't lost any of its blades, and that the clutch is activating. I.e is it turning at a good speed at idle when the truck has warmed up? If not you may need a new fan clutch, or swap to an electric unit

    I just fisished flushing the radiator. It didnt look too bad and not a lot of junk came out but the ac condenser was packed with dust and bugs. So it got sprayed out really good. In the process of putting it back now.

    See how it goes. The stuff that gets stuck in the tubes wont come out from a flush. But if the condenser was packed full it would have a noticeable effect

    Radiator seems to have good flow thru it. And it it ran cooler after cleaning. But I'll have to see how it does on a warm day again it had cooled down quite a bit from earlier today.
