Jeep won't stop overheating and burning coolant

My '02 TJ (six cylinder) will not stop burning coolant. It's getting to the point that it's burning off a topped off radiator's full of coolant nearly everyday.

Any ideas on what I can start checking to find out what I need to fix/replace?

Blown head gasket. Good luck finding a replacement gasket with that V-6 you have.

Look at your oil, is it milky like a shake? Any puddles? No way a weeping hole could make you lose that much coolant.

its an inline 6, and if its burning coolant you have a blown head gasket and will have to take it to a shop to get it repaired. are you seeing white smoke form the exhaust pipe? is youre oil milky? these are signs of a blown head gasket.

What makes you say it's "Burning coolant"? Have you pressure tested for coolant leaks?

Do a pressure test before jumping on the wagon of the blown head gasket. We need the whole story. Did you replace anything recently? Water pump, radiator, radiator fluid, thermostat?

What else could it be that would make the OP lose that much coolant? If it were a leak it would be noticeable, so there's really only one more option. Nevertheless, a pressure test wouldn't be a bad idea.
