OK, then I'll answer it: First, the heater core is always "on", meaning it has circulation even when the AC is running, but that circulation pathway changes during warm up. The M96 has a bypass coolant circuit that allows some low level volume of coolant to circulate while the thermostat is fully closed. This circuit is actually there to help prevent head cracking as they get hot very quickly. As soon as the stat begins to open, much warmer coolant begins to flow at a much higher volume rate, giving the driver much more heat.
