The overflow tank is full and bubbling out out the the holes in the cap.So when you open the hood when its overflowing, is the overflow tank at the "high" mark or at the "cold" mark still? Make sure that tube on the outlet of the rad going into the overflow tank is clear and not plugged. If the tank isn't cycling fluid then it's most likely the rad cap.
Travelled that highway a lot towing my trailer and quads!!! It’s a beast!Yes, in Medford, Oregon. 89 miles north & 32 miles north of state line. Three hard pulls between here and there.
You have too much fluid in it then. When the truck is cold, is the level on the cold mark? Otherwise you might have another issue as well.The overflow tank is full and bubbling out out the the holes in the cap.
being full and bubbling. two things come to mind. clog or air. since its been driven a while now, im guessing we can rule out air.You have too much fluid in it then. When the truck is cold, is the level on the cold mark? Otherwise you might have another issue as well.
Fluid level is within cold range markings on the reservoir when it's cold. Stays pretty close to that level even after driving it for a while unless I turn it off.You have too much fluid in it then.

Have no idea what the maintenance history or usage of the truck prior to my ownership so a clog wouldn't be ruled out.being full and bubbling. two things come to mind. clog or air. since its been driven a while now, im guessing we can rule out air.
I would definitely try a new radiator cap! The cap is rated for a certain PSI of pressure which keeps the coolant from boiling and pushing passed the cap to the reservoir, if the cap is old with a weak spring and or bad gasket it will cause what sounds like your problem. "The radiator cap acts as a release valve set to open at the maximum pressure point. Usually this is set at a density of 15 pounds per square inch (psi). When the fluid pressure inside the radiator exceeds 15 psi, it forces the valve open, allowing heat to escape and excess coolant fluid to overflow into the tanks on either side of the radiator."Have no idea what the maintenance history or usage of the truck prior to my ownership so a clog wouldn't be ruled out.
I agree. I would have replaced the radiator cap immediately. Inexpensive first attempt at symptoms.I would definitely try a new radiator cap!
