So I was under the hood of my 05 Grand Cherokee yesterday, checking oil, etc.
I notice the radiator overflow tank is empty. Filled it back up to between the "add" and the "full" line. Pull the radiator cap, and add about a quart to get it back up to the top.
Drove it to church and dinner last night, maybe 40 minutes driving total.
This morning I go back out and check it, the overflow tank is completely empty, open the radiator and add about 2 quarts, then refill the overflow.
There is no sign of any leaks on the ground, or under the chassis that I can see. Not blowing any white smoke out the tailpipe, which should be happening if its got a blown head gasket and its burning antifreeze.
It's got to be going somewhere, but I'm lost
