Sb01box is right. The water heats up after shutting down the engine and then exceeds the ability of some part to hold the pressure,

I did a little troubleshooting this morning and a few minutes after I shut her down she dumps some coolant so now I know the timing

It is coming from the drain built into the black top of the tank so it has to be the cap, the relief valve or some hairline crack in the top itself and not the body of the tank or it would be leaking into the trunk

The cap and relief valve are new so now that I know how long to wait for the leak i am doing another test run tomsee if I can pinpoint exactly where the fluid Is leaking

Would be simpler if I had the eq to pressurize it and look for the leak that way

Experienced owners are chuckling but maybe other novices can learn from my struggles
