Awesome, thanks for the info. Haven't really looked under the hood to check yet. Car is in for inspection and they called me and mentioned a coolant leak at one of the elbows. Also said it could take them 2hours because the supercharger. But they seem to be full of s***. Looks like well less than an hour to me. Will tell them to leave it be and I will fix it myself.

I will finally flush and switch to the green coolant while I am it. Get rid of that sloshing hopefully, too.
