So I was raised in a place where heat was much more of an issue than cold, so I grew up hearing that you can use the heater for the passenger compartment to cool the engine, effectively using the heaterbox as a second radiator. Now that I am living in a place that snows, I am being told that on cold mornings, the fastest way to bring the engine safely to temperature is to blast the heat, because the thermostat will run the engine hotter to bring the passenger compartment warmer air.
I have no doubts that modern cars can do that, but I am curious about how the engines bring it up to higher temps. Do they just idle at a higher rpm? How would being driven affect having more heat requested?
on a side note, I am immensely amused that my car is not listed as an option XD I have a '17 Mazda CX-3. Quite a few websites do not list my model car, which is a shame, it’s a darling little car that I could not be happier with.
