Thanks for the reply! My understanding was that the thermostat tries to keep the coolant at a certain temperature. The coolant going above that temp can obviously be problematic but keeping the coolant too cool is also not ideal. If your cooling system is not allowing your engine to reach or maintain the normal operating temperature then that is when "you would want to reduce it." At least that is what I've concluded. Let me know if I'm misunderstanding something.

Really? I admit I'm no expert on this stuff but it seems kind of intuitive that a high CFM would meaningfully increase the system's ability to cool compared to little or no airflow. My thinking is that if a high rate of airflow through the radiator makes it cool the fluid significantly more, then wouldn't that result in the thermostat reducing the flow of coolant compared to the same scenario with low airflow? Or does rate or airflow simply not have much affect the radiator's ability to cool the fluid?

, What have you been reading to make you think otherwise? |
My apologies if I'm misunderstanding but it sounds like maybe we're saying the same thing in two different ways?
I was talking about the thermostat reducing coolant flow when the full cooling capacity of the system isn't needed. Isn't that the same as your point about thermostats having "varying degrees of open"? Like "more open = more flow" and "less open = reduced flow"?
