Driving a quick 300 mile trip to west texas and my truck for the first time ever ever ovrheated. I have 545K on stock everything. I stop driving for 3 hrs let all the liquieds cool off, Re fill the coolant and it takes about 5 gallons. I did pull te termostat cut out the spring and inners and put it back in, I was not sure if i was stuck, Water pump is not leaking, The clutch fan, Well I do not know how to check that. But where is all this coolant going. No leaks as I sat under the truck for 30 mins as it cooled and found nothing.
I am lost. Can an injector cup leak to the point were the coolant can be evaporated in the combustion camber?
I can drive 60 miles then it starts to overheat so I have to pull over, Let everything cool down, Add all the water/coolant then start back on my drive home. No trailer this trip.
I'm lost. And help please.
As I said, Oil is clean, No diesel in coolant.
Could the oil get so hot ( 60 miles ) ten the coolant starts boiling and disappating?

sounds like head gaskets, that would be my guess with the miles you have on it,, the coolant is going some where and if you don't find it leaking anywhere it's going into your cylinders and been burned,, are you getting any white smoke from exhaust,,, blown head gaskets don't always cause white smoke and you won't always get coolant into your oil either ,,,, so just because you don't have coolant in your oil don't mean you don't have a blown head gasket,, does your year truck have a egr cooler trying to help best that I can
