Sorry to say also sounds like a head gasket but there is something you can try with no promises and at this point it is worth a try. Bars cooling system stop leak. If it does not work first time do not continue to add more hoping it will work that is when you can clog up the cooling system.

Actually 2 applications of Bars Leak is fine. I needed a second one to seal up the leaks in my '03 GP. If your gaskets are not leaking too badly that may well work and save you a ton of money. I solved my coolant loss problem with Bars Leak 5 years ago and so far have not had to change the gaskets.
