Coolant missing
Anyone having a problem with coolant going away and no signs of a leak, have had it at the dealer know for 3 days under pressure for over 24 hrs. & lost only 2 psi., it's just a real slow leak, could it possibly going strait out the exhaust.

this happened to me also, while looking under the hood one day after an oil change i noticed the hose that goes to my overflow tank from the radiator was bent at a 90 degree angle blocking any thing from going to the overflow or radiator. the bend was butted up against the radiator shroud which looks like that's what caused it, almost like a design flaw. they rerouted and replaced it with a stronger hose and since i have had no problems with low coolant.

Loosing coolant
Every time I drive for about 20 miles or so, I find that my coolant recovery tank is 1/2" lower after the engines totally cools down. I removed the recovery tank and checked it for leaks. Replaced the coolant recovery clamps, and both clamps on the middle radiator cap connection.
I cannot smell any coolant or see any dripping. I park with a piece of cardboard under the car, and not drips.
Has anyone had problems with a radiator cap leaking? Or some hoses in the back side of the engine near the firewall?
Mine is an 08 SS with 41,000 miles.

I had a super slow leak at the heater core connections through the firewall.
I ended up having to use worm clamps to seal it up, the GM clamps wouldn't hold closed tight enough under boost and I would get a super slow leak.
The only way I knew I had a leak is there was some down on the rear Motor mount bolt area when I changed my DP out.
If you are positive all hoses are sealed up tight, you could have a possible porous block. There has been a few LNF's with it.

Sleeper,
The oil dipstick has only light golden colored oil on it. No white paste etc present. Same for the oil fill cap, clean.
HHRSSouth,
I am going to re-inspect the heater hoses and the hoses around the thermostat housing. My goal is te eleminate any weak hose clamps before having the problem evaluated by a dealer.
