    I have a 2005 Grand Cherokee Limited, 4.7 liter. Over the past several months it started losing coolant but I have been under it, over it from every angle possible and see no sign of leaks anywhere. No water in my oil or oil in my water. Is it possible to have a blown head gasket and only lose coolant through the exhaust but no other symptoms?

    Might not see a lak, if its loosing coolant while driving. Do you smell coolant while driving, or when parked?

    try this - rent beg and or some how borrow a cooling system pressure tester, and get a bottle of UV dye for coolant...
    the pressure tester allows you to really move about the engine easily and safely as you use a black light to find the UV leak trail or evidence- look at the evaporator drain, the carpet on passenger side, head gasket sealing area, inspecting spark plugs MAYBE some dye on them or a single plug may have a steam cleaned appearance compared to the others, a tell tale symptom.

    I don't smell any coolant, one of the differences between Mopar coolant and Prestone type coolant is Mopar doesn't smell, at least I can't smell it. No staining or wet spots on passenger floor board, I was thinking along them lines too, heater core. I never heard of a pressure tester for cooling systems but perhaps a local mechanic would know or have one. I spent a half hour under and above it yesterday, with it running after a 50 minute drive, skid plate removed and a very bright light. There is no indication of leaks anywhere.
