Coolant Disapears

[kwats1928]

I keep adding coolant to my reservoir about a gallon a week. I checked the heater core and it is not leaking. Also not getting a lot of condensation out of exhaust. Any ideas? 2003 Ram 1500 with 4.7 engine.

A gallon a week? You HAVE to be burning it. I would do a compression test. See if there are any cylinders that are low (chances are there will be at least 2 next to each other).
