2012 Chevy Sonic 1.8 - "Chocolate Milkshake" in Coolant Reservoir

It won't take much. Give it maybe a 1/4 cup. Yes, then a couple of rinse cycles.
I've done this on big Caterpillar engines and poured in the entire bottle.

That Opel was kind of a cool little engine. In fact, the entire car was actually cool. It had the four cam six, four wheel independent suspension with four wheel disc brakes and 16" alloy wheels. I think it was an L300. It survived a bunch of years with my wife and both of her kids getting their licenses.

How long do you run it with the Cascade? Half an hour or so? At least long enough to get the thermostat open I figure.

Exactly.
