Hi Jamie,

        I’ve heard of this happening to some folks.  Some part of the system contracting and letting out coolant. 

        I’m one of the least Savvy on the list, but one thing I might try is to pressurize the system.  You could do this outside when things are colder, but even in your garage it might work.  This might at least help you track down the source of the leak. 

I have a little device from GW that goes on the Reservoir and you can pump up.  I usually go to about 15 PSI, Bentley will have the pressure ranges. 

Then I have sighted help or listen to see if I can find the leak source. 

Let us know how it goes.
