Added one step. Bubbles rise, so the higher the front end, the better. Bleed screw or radiator cap will work. I've never been able to loosen my bleed screw, so I stick with the cap method. Plus with the cap off, you can see the bubbles as they rise and when they cease.

1a - Jack the front end high as you can get it.
1b-remove the radiator/reservoir cap when the engine is cold
2-start the engine and let idle
3-turn the heater on max
4-keep coolant on hand and add it as needed
5-some coolant may gush out with the air
6-keep doing this until the engine is at operating temperature and the heater is hot
7-after the coolant settles down and the engine is warm,,install the cap
This may take as long as 20-30 minutes

ive been told by multiple people to bleed it at the air screw and not the other way and then I’ve been told the opposite and not use the bleed screw

Has your truck always run hot at highway speeds since you have had it?
Do you have an expansion tank installed?
