I thought I understood the coolant reservoir but maybe I'm missing something.

My Civic got pretty hot a couple times recently. It vented coolant into the reservoir but it seems to stay there unless I pour it back into the radiator myself. Isn't it supposed to get sucked back in automatically??

Does it mater whether I vent it later after it cools a bit by loosening the radiator cap?

If you're wondering why it got hot (227 deg F this morning!!), it was due to too much grill block and me not paying attention to the ECT display in ScanGauge. Yakking with carpool buddy. My bad.
