[Shotimes] t-stat temp dumb Q

[bjshov8]

The difference is just that, the temperature that the thermostat
theoretically opens at.  The engine will run a bit hotter or cooler
depending on what thermostat you have.  Cars these days are calibrated to
run at certain temperatures, change the thermostat significantly and it can
affect the operation of the engine management system.  Otherwise it isn't
rocket science, and I think one car maker's guess as to the right
temperature might be just as much a random guess as another car maker's
guess.  In a non-computerized engine, it doesn't make all that much
difference.

As for warming up time, it will take just as long for the engine to warm up
to reasonable temperature with one thermostat as another.  Obviously it will
take longer for an engine to reach 190 as it will to reach 180, but this
doesn't really matter.  Most cars bypass the thermostat with water going to
the heater, so the heater will work when hot water is available no matter
what the thermostat is.
