Good stuff, this thread. To reiterate a pickup & car difference:
The vehicles with an expected work load (pickup trucks, especially diesel-powered ones) have truly large coolant systems (capacities for a given displacement). In fact, that capacity is an important limiting factor while in service (defining what work is possible). Why pickups tend to be as large as they are, IOW, is the cooling system.
Getting up to op-temp quickly, solo/unladen or towing/heavy, is a
prime FE consideration (not just one of engine longevity).
A "winter front" is great, but shutters take it to a more practical level for year-round use.
