Puking coolant and running hot while climbing

[gblauf]

I have an 06 f350, i was climbing up a very mild grade pulling a very small trailer with 2 dirtbikes on it, 4% grade for 10 miles at 60 mph, outside temp was in the 40's. coolant puked all over the place, and the fan kept kicking on. My temp gauge never moved. But it must be getting hot.

I have replaced my degas cap, egr cooler, thermostat and coolant.. I do not believe that headgaskets play a role in this.

Any ideas???

You really need to see what your pcm is seeing. You need a scanner or monitor.
The dash gauges are just about useless. You could have serieous problems to just overfilling the coolant bottle. The newest updated full line is just below the minimum line on the bottle.

agreed^^^^ never trust your factory gauge mine climes to 230 once on my sct livewire and the factory was smack dab in the middle, and dannyboy is correct only fill to one inch below the correct level line or it will puke, also i have heard from many it only takes one or two times to fry the de-gas cap so make sure you get a new updated cap from the stealership which most do not know that there is one...
