Hi Scott,

Doesn't the thermostat prevent coolant from flowing to the rad if the
engine is below its target threshold?

In which case a short-circuited cooling hose or an open-flowing heater
core can't affect warmup, because (as I understand it) there's no
coolant flow out of the engine bay until the engine reaches its optimum
temperature.

I never worry about turning on the heat too soon in winter... because in
my 46 years of experience with long Canadian winters you don't get any
until the engine is ready to give it to you anyhow.

Unless you use a gas or propane furnace, that is.

Happy Trails,
