My wife has a 2003 Jeep Liberty with a 3.7 V6. I have needed to add a quart or more of coolant every week for the past month. I can't find the leak.

- I have had the system pressured checked by a shop. It held pressure okay.
- No drips on the ground.
- I have looked all over the engine while it was running at operating temp and no signs of a leak.
- Hoses are in good shape.
- No water in the oil.
- Check the heater core, no leaks.
- Tried a can of Bar Stop leak stop gunk - no luck.

Hoping it's not a head gasket. (I thought the pressure check would show something like this) Is there a way to check for that?

Does anyone have any suggestions what else to check?
