I have a 2005 f250 6.0diesel. It recently started using alota antifreeze. I've checked the oil for water, there's no leaks that I can see. The exaust isn't blowing water out either. Was wondering if any one had a problem like this? If so please give suggestions!!

Hi,
Best guess is that though you see no symptom other than the antifreeze level, is that you have a blown head gasket. If it blows in certain places, the only thing you will notice is that the fluid level(s) drop.
Peace,

Start by pulling your egr valve out and check for soot, also check for any moisture, because it sound to me that you egr cooler is leaking. The coolers main function is to cool exhaust gases for emissions.
