You probably need to let the car fully cool, start it and look right away. You probably only have a leak until things expand and that plugs it, so it's only when it first starts up. I have seen this before where hose connections are. Good luck!! Dan
You should not be seeing any "rusty" water if you have coolant in the system. Are you seeing the Dexcool orange, or actual rusty water?
If you don't have coolant in the system, that could be part of the problem.
If you are smelling coolant, check to make sure your radiator tank cap is holding pressure, and there is not any fluid deposits around the weep hole on the water pump.

It is probably the seal on the front of water pump. Hard to see, hard to get to, behind the pully, but if you wipe it with your finger you can prove if it is coming from there.
Also, you have low or no pressure on the system when the car is cold and just started. When it is fully warmed up you have full pressure on the coolant and the leak will be seen.
