Coolant reservoir empty and no heat from heater.

Driving the truck back home from kansas city, MO last night and heater would not get hot at all. I looked under the hood and noticed that the decant bottle was empty. I was running the 250 tune and I have head studs already. When I stoped I put 2 gallons of coolant in the truck and the heater worked like a champ agin. When I stoped for fuel the second time reservoir was empty agin and it took 1 1/2 gallons to fill it up this time. I cant find the leak but it sounds like I can hear coolant hitting something hot while driving. The temp of the truck never did get hot so I dont think its loosing enough coolant to overheat. The temp last night was 29 degrees also. Any ideas? EGR cooler?

I know of a few upper radiator hoses that have failed on our trucks. Ford actually has a "revised" upper hose that has two o rings in it instead of one. If it was leaking from the upper hose you would see coolant on the under side of your truck though.

If it was an EGR cooler you should be blowing steam out of the exhaust.

Yeah no steam out of the exhaust so thats a plus. I just took the truck to the dealer so we will see what they say. I did see some coolant under the truck when i was filling up it was right under the drivers side front tires but I couldnt see where it was comming from.

Radiators are not job specific.

I've put 'em in job 1/2/3's as well as a couple 09's also.

I have seen the upper radiator, and EGR coolant hose be the most common leaks. Lower EGR cooler rear-most coolant connection seems to be problematic. Or you have a small internal crack that is slowly burning the coolant. But with you noticing the coolant behind the front tire drivers side, i am leaning to EGR cooler or radiator hose. Seems to be losing a lot though, if you are going through that much coolant.
